An international collaboration called BioRescue has taken a step forward in bringing back the Northern White Rhino with the creation of three embryos, which it hopes to bring to term in a surrogate in the coming months.

The BioRescue team, including researchers based at the Leibniz Institute for Zoo and Wildlife Research, Germany, extracted egg cells from the ovaries of the last two remaining northern white rhino females. They then artificially fertilized the eggs using sperm taken from now-deceased male rhinos and stored the embryos in liquid nitrogen. The team managed to create two embryos in September 2019 and has recently created a third.

Before the BioRescue team came, no one had ever created an embryo from a northern white rhino except for the rhino itself, Steven Seet, Head Public Relations & International Affairs at the Leibniz Institute for Zoo and Wildlife Research, told me. This species is functionally extinct. Nevertheless, we have achieved the production of a third embryo now. This is incredible.

As the last two females are unable to become pregnant, the plan now is to implant the embryos into surrogate female southern white rhinos, a distinct subspecies, in the coming months. Every additional embryo increases the probability of getting a pregnancy The more, the better! Seet said.

There are many technical challenges remaining before the team can save the Northern White Rhino from extinction. First of all, it will need a lot more than three embryos to rebuild a healthy population. To meet this challenge, the team is developing technology to transform stem cells from northern white rhino skin tissue into egg and sperm cells. Our Japanese cooperation partner succeeded in doing so in a mouse model, Seet said. We are adapting this to the rhinos.

A second challenge may lie in implanting a northern white rhino embryo into a surrogate southern white rhino mother, which might have compatibility issues.

It might be that there are epigenetic components involved as the biological system of the southern rhinos might differ from the northern, Seet told me. A possible assessment of this could be conducted when we have the first calves on the ground. This is further research then.

Also involved in the BioRescue project was the German big pharma Merck KGaA, which donated a specialized incubator where the egg cells could be fertilized with monitoring by HD cameras.

Merck has donated access to its innovative fertility technologies to Project BioRescue to give this challenge the best possible chance of success and protect the Northern White Rhino from extinction, Jan Kirsten, Mercks Head of Global Business Franchise for Fertility, told me. While there is a long way to go on this journey, we hope these steps will pave the way for this technique to potentially be used in other species.

According to Kirsten and Seet, the biotechnology industry will likely play a strong role in the conservation of endangered species in the coming years. However, argued Seet, reproductive medicine and stem cell technology should remain a last resort to save a species.

It would be better to react much earlier to avoid using the BioRescue technology, he said. Humans must learn from this best practice project and evaluate biodiversity and conserve it.

WASHINGTON - Scientists in the United States created the first living robots using stem cells, which can move toward a target and heal themselves after being cut. A study published on Monday in Proceedings of the National Academy of Sciences described the living, programmable organism, a completely new biological machine designed from ground up. Scientists at the University of Vermont ran an evolutionary algorithm on a supercomputer to screen out a design to be composed of single frog skin and heart cells.

Then, scientists at Tufts University transferred the in silico design into life with stem cells harvested from embryos of African frogs. They used tiny forceps and electrode to assemble the single cells into a close approximation of the computer designs.

They found that the skin cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion, allowing the robots to move on their own.

Those millimeter-wide reconfigurable organisms were shown to be able to move and explore their watery environment for days or weeks, according to the study.

They could move around in circles, collectively pushing pellets into a central location. Its a step toward using computer-designed organisms for intelligent drug delivery, said Joshua Bongard, a computer scientists at the University of Vermont.

We can imagine many useful applications of these living robots that other machines cant do, said Michael Levin at Tufts University, like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque.

In another test, the scientists cut the living robots and watched what happened. We sliced the robot almost in half and it stitches itself back up and keeps going, said Bongard.

Right now, your bodys stem cells are working hard replacing your skin every two weeks, creating new red and white blood cells and completing thousands of other tasks essential to life. They are your own personalized fountain of youth.

Scientists generally agree that a stem cell should be able to do both of the following:

One theory of ageing suggests that between the ages of 30 and 50, our stem cells reach a turning point and start to decline in number and function. This results in the typical features associated with ageing.

There does not seem to be a single discoverer of stem cells. Accounts date back to the 1800s and even further, but the first successful medical procedure was a bone marrow transfusion in 1939. Advances in immunology led to donor matching, initially via siblings and close relatives. Unrelated donor matching flourished in the 1970s, alongside donor registries.

In the 1980s, scientists identified embryonic stem cells in mice, leading to the 1997 cloning of Dolly the Sheep. This created immense interest for human and medical applications and a backlash in the US as federal R&D funding was essentially halted in 2001.

In 2012, a Nobel Prize was awarded for the earlier discovery of induced pluripotent stem cells (iPS). Essentially, they return potency and self-renewal properties to mature non-stem cells, essentially making them act like stem cells again.

In the decade between 2010 and 2019, the first wave of stem cell start-ups emerged, alongside R&D programmes at many large pharmaceutical companies, leading to innovation and the first human clinical trials for iPS and other related therapies.

According to Q3 2019 data from the Alliance for Regenerative Medicine, there are 959 regenerative medicine companies worldwide sponsoring 1,052 active clinical trials; 525 of these companies are in North America, 233 in Europe and Israel, and 166 in Asia. In aggregate, $7.4 billion has been invested in regenerative medicine companies in 2019; $5.6 billion of which has been dedicated to gene and gene-modified cell therapy, $3.3 billion in cell therapy, and $114 million in tissue engineering.

Overview of the cancer stem cells market

Perhaps most excitingly, curative therapies are hitting the market and the results are astonishing: 60% of Acute Lymphoblastic Leukemia patients taking Novartis Kymirah showed a complete response (no traces of cancer) and were declared in full remission. Meanwhile, 75% of patients with Transfusion-Dependent -Thalassaemia treated with bluebird bios Zynteglo achieved independence from transfusions. Perhaps most astonishingly, 93% of spinal muscular atrophy patients treated with Novartis Zolgensma were alive without permanent ventilation 24 months after treatment. We should expect more medical breakthroughs in the coming years.

New science, new start-ups: several companies in the sector have gone public or been acquired. These exits led to the recycling of talent and capital into new companies. Because the science and commercial systems have also advanced, the companies in the next wave are pursuing bigger challenges, driving innovation, with even greater resources.

Patients are eager: the current market for stem cell therapies is growing at 36% per year, though it will rapidly expand when a breakthrough occurs toward the treatment of a non-communicable disease (such as cancer, diabetes, heart disease) or a lifestyle factor (for example, growing hair in the correct places, expanding cognitive abilities or increasing healthy lifespan).

New R&D models: funding is flowing into the sector from large companies, VC funds, and institutions such as the California Institute for Regenerative Medicine (CIRM) and New York State Stem Cell Science programme (NYSTEM). Some of the leading university R&D platforms include the Center for the Commercialization of Regenerative Medicine in Toronto, the Stanford Institute for Stem Cell Biology and Regenerative Medicine, the Oxford Stem Cell Institute, and most notably, the Harvard Stem Cell Institute (HSCI).

Founded in 2004, HSCI has established a phenomenal track record. It provided the first $200,000 in funding to Derrick Rossis lab, which inspired the largest biotech IPO to date. HSCI scientists were also co-founders or principals in the three most prominent gene-editing companies (CRISPR Tx, Intellia and Editas), the combined $1.55-billion True North/iPierian acquisitions and the recent $950-million acquisition of Semma Tx, Frequency Tx, Fate Tx, Epizyme Inc., and Magenta Tx.

For the casual investor, Evercore ISI is building a Regenerative Medicine Index, which may be the simplest way to build a portfolio. For institutions and those with deeper pockets, regenerative medicine funds are forming, including the Boston-centric Hexagon Regenerative Medicine Fund, which aims to create companies out of the Harvard Stem Cell Institute.

Caveat emptor. Though patients needs are immediate, those seeking treatments should think very carefully about the risks. There are many dubious clinics touting expensive stem cell treatments and some patients have experienced horrifying complications. Dr. Paul Knoepfler of UC-Davis has written a practical and scientifically accurate guide, a strongly recommended read if you or a family member are considering treatment or a clinical trial.

The leading causes of death in 1900 were mostly infectious/communicable diseases. While the prevalence of most causes has diminished, the largest increases include heart disease (+40%) and cancer (+300%). Granted, this is partly due to doubling life expectancy and a lack of death from other causes. However, given time and resources, scientists and physicians may cure these challenging diseases.

Total disease burden by disease or injury

Today, six of the seven leading causes of death are non-communicable diseases (heart disease, stroke, lung diseases, cancer, Alzheimers disease and diabetes). Based on the early promise mentioned above, regenerative medicine may be our best hope to solve the great non-communicable diseases of our time, and perhaps the single most transformative medical innovation in a century.

Why stem cells could be the medical innovation of the century - World Economic Forum

Skin Stem Cells Comments Off on Why stem cells could be the medical innovation of the century – World Economic Forum | January 17th, 2020

What happens when you take cells from frog embryos and grow them into new organisms that were "evolved" by algorithms? You get something that researchers are calling the world's first "living machine."

Though the original stem cells came from frogs the African clawed frog, Xenopus laevis these so-called xenobots don't resemble any known amphibians. The tiny blobs measure only 0.04 inches (1 millimeter) wide and are made of living tissue that biologists assembled into bodies designed by computer models, according to a new study.

These mobile organisms can move independently and collectively, can self-heal wounds and survive for weeks at a time, and could potentially be used to transport medicines inside a patient's body, scientists recently reported.

Related: The 6 Strangest Robots Ever Created

"They're neither a traditional robot nor a known species of animal," study co-author Joshua Bongard, a computer scientist and robotics expert at the University of Vermont, said in a statement. "It's a new class of artifact: a living, programmable organism."

Algorithms shaped the evolution of the xenobots. They grew from skin and heart stem cells into tissue clumps of several hundred cells that moved in pulses generated by heart muscle tissue, said lead study author Sam Kriegman, a doctoral candidate studying evolutionary robotics in the University of Vermont's Department of Computer Science, in Burlington.

"There's no external control from a remote control or bioelectricity. This is an autonomous agent it's almost like a wind-up toy," Kriegman told Live Science.

Biologists fed a computer constraints for the autonomous xenobots, such as the maximum muscle power of their tissues, and how they might move through a watery environment. Then, the algorithm produced generations of the tiny organisms. The best-performing bots would "reproduce" inside the algorithm. And just as evolution works in the natural world, the least successful forms would be deleted by the computer program.

"Eventually, it was able to give us designs that actually were transferable to real cells. That was a breakthrough," Kriegman said.

The study authors then brought these designs to life, piecing stem cells together to form self-powered 3D shapes designed by the evolution algorithm. Skin cells held the xenobots together, and the beating of heart tissue in specific parts of their "bodies" propelled the 'bots through water in a petri dish for days, and even weeks at a stretch, without needing additional nutrients, according to the study. The 'bots were even able to repair significant damage, said Kriegman.

"We cut the living robot almost in half, and its cells automatically zippered its body back up," he said.

"We can imagine many useful applications of these living robots that other machines can't do," said study co-author Michael Levin, director of theCenter for Regenerative and Developmental Biologyat Tufts University in Massachusetts. These might include targeting toxic spills or radioactive contamination, collecting marine microplastics or even excavating plaque from human arteries, Levin said in a statement.

Creations that blur the line between robots and living organisms are popular subjects in science fiction; think of the killer machines in the "Terminator" movies or the replicants from the world of "Blade Runner." The prospect of so-called living robots and using technology to create living organisms understandably raises concerns for some, said Levin.

"That fear is not unreasonable," Levin said. "When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences."

Nevertheless, building on simple organic forms like the xenobots could also lead to beneficial discoveries, he added.

"If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules," Levin said.

The findings were published online Jan. 13 in the journal Proceedings of the National Academy of Sciences.

World's First 'Living Machine' Created Using Frog Cells and Artificial Intelligence - Livescience.com

Skin Stem Cells Comments Off on World’s First ‘Living Machine’ Created Using Frog Cells and Artificial Intelligence – Livescience.com | January 16th, 2020

Scientists have created the worlds first living robots out of frog stem cells, according to new research. These tiny new lifeforms can be programmed to move around or carry and deliver miniature payloads that could one day be medicines inside a patients body, the Guardian reports.

The scientists knit skin and heart cells scraped from the embryos of African clawed frogs (Xenopus laevis) into 3D shapes designed by artificial intelligence to accomplish certain tasks.

These are entirely new lifeforms. They have never before existed on Earth, study co-author Michael Levin told the Guardian. They are living, programmable organisms.

The living robots, called xenobots after the clawed frogs Latin name, measure 0.04 inches and have enough energy inside them to keep moving for seven to 10 days before calling it quits.

The squishy robots dont have the strength and durability of plastic or metal machines, but biology affords them some unique advantages. They can heal themselves if wounded, and when their biological engines run out of fuel the xenobots simply fall apart and decay. This last part is crucial when it comes to potential medical or environmental applications in which leaving behind shards of plastic or metal presents obvious problems.

The researchers said we cant know for sure what applications await the soft-bodied bots, but imagined uses including cleaning up microplastics in the ocean, digesting toxic materials at polluted sites or scooping plaque from inside human arteries. Apart from scooting around in petri dishes, the researchers also say tinkering with these living machines could help scientists better understand the software of life.

The first generation of xenobots are tiny, but the scientists say the plan is to scale up perhaps even to living robots with blood vessels and nervous systems that can live on dry land.

If the voice of Jeff Goldblums character from Jurassic Park is beginning to echo in the back of your mind, youre not alone: When youre creating life, you dont have a good sense of what direction its going to take, Nita Farahany, who studies the ethics of new technologies and was not involved in the study, told Smithsonian. Any time we try to harness life [we should] recognize its potential to go really poorly.

For their part, the creators of the xenobots acknowledged the potential ethical implications, but say its up to society and policymakers to decide what those might be.

I think theyd acquire moral significance only if they included neural tissue that enabled some kind of mental life, such as the ability to experience pain, ethicist Thomas Douglas told the Guardian. But some are more liberal about moral status. They think that all living creatures have interests that should be given some moral consideration. For these people, difficult questions could arise about whether these xenobots should be classified as living creatures or machines.

SCIENCE

Newswise A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need.

Now a team of scientists has repurposed living cells--scraped from frog embryos--and assembled them into entirely new life-forms. These millimeter-wide "xenobots" can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient)--and heal themselves after being cut.

"These are novel living machines," saysJoshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism."

The new creatures were designed on a supercomputer at UVM--and then assembled and tested by biologists at Tufts University. "We can imagine many useful applications of these living robots that other machines can't do," says co-leader Michael Levin who directs theCenter for Regenerative and Developmental Biologyat Tufts, "like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque."

The results of the new research were published January 13 in theProceedings of the National Academy of Sciences.

BESPOKE LIVING SYSTEMS

People have been manipulating organisms for human benefit since at least the dawn of agriculture, genetic editing is becoming widespread, and a few artificial organisms have been manually assembled in the past few years--copying the body forms of known animals.

But this research, for the first time ever, "designs completely biological machines from the ground up," the team writes in their new study.

With months of processing time on the Deep Green supercomputer cluster at UVM'sVermont Advanced Computing Core, the team--including lead author and doctoral student Sam Kriegman--used an evolutionary algorithm to create thousands of candidate designs for the new life-forms. Attempting to achieve a task assigned by the scientists--like locomotion in one direction--the computer would, over and over, reassemble a few hundred simulated cells into myriad forms and body shapes. As the programs ran--driven by basic rules about the biophysics of what single frog skin and cardiac cells can do--the more successful simulated organisms were kept and refined, while failed designs were tossed out. After a hundred independent runs of the algorithm, the most promising designs were selected for testing.

Then the team at Tufts, led by Levin and with key work by microsurgeon Douglas Blackiston--transferred the in silico designs into life. First they gathered stem cells, harvested from the embryos of African frogs, the speciesXenopus laevis. (Hence the name "xenobots.") These were separated into single cells and left to incubate. Then, using tiny forceps and an even tinier electrode, the cells were cut and joined under a microscope into a close approximation of the designs specified by the computer.

Assembled into body forms never seen in nature, the cells began to work together. The skin cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion as guided by the computer's design, and aided by spontaneous self-organizing patterns--allowing the robots to move on their own.

These reconfigurable organisms were shown to be able move in a coherent fashion--and explore their watery environment for days or weeks, powered by embryonic energy stores. Turned over, however, they failed, like beetles flipped on their backs.

Later tests showed that groups of xenobots would move around in circles, pushing pellets into a central location--spontaneously and collectively. Others were built with a hole through the center to reduce drag. In simulated versions of these, the scientists were able to repurpose this hole as a pouch to successfully carry an object. "It's a step toward using computer-designed organisms for intelligent drug delivery," says Bongard, a professor in UVM'sDepartment of Computer ScienceandComplex Systems Center.

LIVING TECHNOLOGIES

Many technologies are made of steel, concrete or plastic. That can make them strong or flexible. But they also can create ecological and human health problems, like the growing scourge of plastic pollution in the oceans and the toxicity of many synthetic materials and electronics. "The downside of living tissue is that it's weak and it degrades," say Bongard. "That's why we use steel. But organisms have 4.5 billion years of practice at regenerating themselves and going on for decades." And when they stop working--death--they usually fall apart harmlessly. "These xenobots are fully biodegradable," say Bongard, "when they're done with their job after seven days, they're just dead skin cells."

Your laptop is a powerful technology. But try cutting it in half. Doesn't work so well. In the new experiments, the scientists cut the xenobots and watched what happened. "We sliced the robot almost in half and it stitches itself back up and keeps going," says Bongard. "And this is something you can't do with typical machines."

CRACKING THE CODE

Both Levin and Bongard say the potential of what they've been learning about how cells communicate and connect extends deep into both computational science and our understanding of life. "The big question in biology is to understand the algorithms that determine form and function," says Levin. "The genome encodes proteins, but transformative applications await our discovery of how that hardware enables cells to cooperate toward making functional anatomies under very different conditions."

To make an organism develop and function, there is a lot of information sharing and cooperation--organic computation--going on in and between cells all the time, not just within neurons. These emergent and geometric properties are shaped by bioelectric, biochemical, and biomechanical processes, "that run on DNA-specified hardware," Levin says, "and these processes are reconfigurable, enabling novel living forms."

The scientists see the work presented in their newPNASstudy--"A scalable pipeline for designing reconfigurable organisms,"--as one step in applying insights about this bioelectric code to both biology and computer science. "What actually determines the anatomy towards which cells cooperate?" Levin asks. "You look at the cells we've been building our xenobots with, and, genomically, they're frogs. It's 100% frog DNA--but these are not frogs. Then you ask, well, what else are these cells capable of building?"

"As we've shown, these frog cells can be coaxed to make interesting living forms that are completely different from what their default anatomy would be," says Levin. He and the other scientists in the UVM and Tufts team--with support from DARPA's Lifelong Learning Machines program and the National Science Foundation-- believe that building the xenobots is a small step toward cracking what he calls the "morphogenetic code," providing a deeper view of the overall way organisms are organized--and how they compute and store information based on their histories and environment.

FUTURE SHOCKS

Many people worry about the implications of rapid technological change and complex biological manipulations. "That fear is not unreasonable," Levin says. "When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences." A lot of complex systems, like an ant colony, begin with a simple unit--an ant--from which it would be impossible to predict the shape of their colony or how they can build bridges over water with their interlinked bodies.

"If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules," says Levin. Much of science is focused on "controlling the low-level rules. We also need to understand the high-level rules," he says. "If you wanted an anthill with two chimneys instead of one, how do you modify the ants? We'd have no idea."

"I think it's an absolute necessity for society going forward to get a better handle on systems where the outcome is very complex," Levin says. "A first step towards doing that is to explore: how do living systems decide what an overall behavior should be and how do we manipulate the pieces to get the behaviors we want?"

In other words, "this study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences," Levin says--whether in the rapid arrival of self-driving cars, changing gene drives to wipe out whole lineages of viruses, or the many other complex and autonomous systems that will increasingly shape the human experience.

"There's all of this innate creativity in life," says UVM's Josh Bongard. "We want to understand that more deeply--and how we can direct and push it toward new forms."

Summary

Scientists at the Sloan Kettering Institute have discovered that the ability of cancers to metastasize to other organs is dependent upon their ability to coopt natural wound-healing pathways. The findings provide a new way of looking at metastasis and its possible treatment.

Metastasis the spreading of cancer to other regions in the body is responsible for 90% of cancer deaths. Yet not much is known about what makes cancer cells capable of metastasizing. Now a major study from investigators at the Sloan Kettering Institute concludes that metastasis-initiating cells employ a devilish trick to spread: They co-opt the bodys natural wound-healing abilities.

The new findings, published January 13 in the inaugural issue of the journal Nature Cancer, provide a novel framework for thinking about metastasis and how to treat it.

We now understand metastasis as the regeneration of the wrong tissue the tumor in the wrong place distant vital organs, says Joan Massagu, Director of the Sloan Kettering Institute and the corresponding author on the paper. This is not just a metaphor. It is literally true in molecular and physiological terms.

There were previously clues that cancers might make use of wound-healing pathways to support their growth. Back in the 1980s, researcher Harold Dvorak dubbed tumors wounds that do not heal. But the new findings present the first detailed picture of how this process works on the level of cells and molecules and there are plenty of surprises.

This is not just a metaphor. It is literally true in molecular and physiological terms.

Though metastasis is deadly, its not something that cancer cells can do easily. To spread, cancer cells must successfully detach from their neighbors, break through tissue layers separating them from the circulation, swim or crawl to a new location in the body through blood or lymph fluid, exit these vessels, then take root and start growing in the new location.

At each step in this process, the majority of loose cancer cells die off. Fewer than 1% of all cancer cells shed from a tumor will ultimately form measurable metastases. But those that do will have proven themselves to be unusually hearty.

Once cancer cells learn how to survive the stress of living in a foreign environment, theyre very difficult to get rid of, says Karuna Ganesh, a physician-scientist in the Molecular Pharmacology Program at SKI and the papers first author. They are a completely different entity from the tumor that they started off in. But not, it seems, because they have different mutations.

Dr. Ganesh and her colleagues wanted to understand what enables some cells to survive this stressful journey. They homed in on a molecule called L1CAM, which previous studies from the Massagu lab had shown is necessary for numerous types of cancer cells to successfully metastasize to organs. Normal healthy tissues do not typically make L1CAM, but advanced cancers often do. Exactly what triggers the expression of L1CAM has so far been a mystery.

From looking at human tumor tissues under a microscope, it was clear to the researchers that dividing cells with L1CAM were more common in areas where an epithelial layer was disrupted that is, wounded. This led the scientists to wonder whether L1CAM is required for normal wound repair, such as occurs in the intestine following colitis. Using a mouse model of colitis, they found that indeed this was the case.

Next, they wanted to know exactly what it is about the wounding process that causes cells to switch on L1CAM. To find out, they turned to a recently developed technology called tissue organoids. These three-dimensional structures are grown from human cells and in many ways resemble human organs. Working with MSK colorectal cancer surgeon Julio Garcia-Aguilar, Dr. Ganesh was able to obtain fresh samples of metastatic colorectal tumors, which she then grew in jelly until they formed three-dimensional tumor organoids.

Using these tumor organoids, she and her colleagues were able to show that simply separating cells from their neighbors was enough to trigger L1CAM production. Whats more, the organoids enabled the researchers to work out in detail the molecular signals that switch on L1CAM.

Why would metastasis-initiating cells share a marker of wound healing? Fundamentally, wounds are a breach in the integrity of the epithelial layer of our skin: Cells that are normally linked tightly to each other to form a protective barrier are suddenly separated from their neighbors. Similarly, in metastasis, cells detach from their neighbors and adopt a migratory behavior to reach new locations. The researchers suspect that the wound repair program equips both types of cells to survive this anchorless state. In the first case, it allows cells to move into the breach and make new tissues, which is a good thing; in the second, it enables metastatic cells to detach and colonize new destinations, which is very bad.

Metastasis is wound healing gone wrong, Dr. Ganesh says.

What Is Metastatic Cancer? Answers to Six Common Questions

Learn about MSKs approach to treating cancer that has spread from the original tumor to other parts of the body.

Since previous researchers had linked cancer growth to wound healing, the SKI scientists asked whether cells that produce L1CAM are necessary to initiate the growth of a primary tumor. Using a mouse model, they found somewhat surprisingly that they were not; tumors formed fine without it. However, these L1CAM-making cells were necessary for tumors to metastasize. This led the researchers to conclude that the stem cells that form primary tumors are different from the ones that form metastases.

Scientists are increasingly interested in cancer stem cells the subset of cells within a tumor than can regrow a tumor. A crucial lesson from these findings is that cancer models that rely on the growth of primary tumors are not adequate for understanding metastasis or for testing medicines that might treat it. Thats because the stem cells that generate primary tumors are fundamentally different from those that generate metastases.

The SKI scientists think that this newly identified connection between metastasis-initiating cells and wound healing will open up promising avenues of research. They are currently looking for drugs that might block L1CAM and thereby rob cancer cells of their ability to metastasize. They plan to continue collaborating with MSK colleagues to bring these insights to the patients in the clinic.

There is such astrong translational environment at MSK, Dr. Ganesh adds. Everybody is eager to collaborate on work that might improve outcomes for patients with metastatic cancer.

Poblano peppers (Capsicum annuum) are a type of chili pepper native to Mexico that can add zing to your meals.

Theyre green and resemble other varieties of peppers, but they tend to be larger than jalapeos and smaller than bell peppers.

Fresh poblanos have a mild, slightly sweet flavor, although if they are left to ripen until theyre red, they taste much hotter.

Dried poblano peppers that are fully ripe and deep red are known as ancho chiles, a popular ingredient in mole sauces and other Mexican dishes.

This article provides a complete overview of poblano peppers, including their possible benefits and uses.

Poblanos are low in calories and rich in fiber and several micronutrients.

In fact, 1 cup (118 grams) of chopped raw poblano peppers provides (1):

Poblanos are particularly rich in vitamins A and C. These two nutrients act as antioxidants in your body and help fight underlying damage from free radicals, which may lead to disease (2).

Dried poblano peppers, or ancho chiles, have higher amounts of vitamins A and B2 and other nutrients, compared with fresh poblanos (3).

Poblano peppers are rich in fiber, vitamins A and C, and several other nutrients.

Due to their high amounts of nutrients and beneficial plant compounds, poblano peppers may provide health benefits.

However, there is no substantial research on the health effects of eating poblanos in particular.

Poblanos and other peppers in the Capsicum annuum family are rich in antioxidants, such as vitamin C, capsaicin, and carotenoids, some of which turn into vitamin A in your body (4).

Antioxidants help fight oxidative stress caused by excess free radicals.

Free radicals are reactive molecules that lead to underlying cell damage, which in turn may increase your risk of heart disease, cancer, dementia, and other chronic conditions (5).

Therefore, eating antioxidant-rich poblanos may help prevent illness related to oxidative stress (6, 7).

Capsaicin, a compound in poblanos and other peppers that imparts a spicy taste, may exert anticancer effects.

Specifically, capsaicin may influence genes involved in the spread of cancer and promote cancer cell death, though its role in this process is not fully understood (8).

Test-tube studies suggest that capsaicin may exert anticancer activity against human lung and colorectal cancer cells (9, 10).

However, a review of 10 observational studies in humans found that low capsaicin intake was associated with protection against stomach cancer, while medium-high intake may increase the risk of this disease (11).

More research is needed to fully understand whether eating poblano peppers and other foods with capsaicin has anticancer effects.

Capsaicin may also fight inflammation and help alleviate pain.

Some studies suggest that it binds to nerve cell receptors and, in turn, decreases inflammation and pain (12, 13).

There is limited research on the effects of dietary capsaicin, especially from poblano peppers, on pain. Still, studies in humans and rats suggest that capsaicin supplements may fight inflammation (14, 15).

One study in 376 adults with inflammatory bowel diseases and other gastrointestinal issues found that capsaicin supplements prevented stomach damage (14).

Still, be sure to consult your healthcare provider before taking capsaicin supplements to treat a medical condition.

Poblano peppers are loaded with vitamin C, a water-soluble nutrient thats vital to immune function. Not getting enough vitamin C can lead to an increased risk of developing an infection (16).

Whats more, the capsaicin in poblano peppers has been linked to optimal immune function.

Several animal studies have shown that capsaicin may influence genes involved in the immune response and help protect against autoimmune conditions (17, 18).

While theres no substantial research on the health effects of eating poblanos specifically, studies on the compounds in these peppers suggest that they may have anticancer effects, help fight inflammation, and even boost immunity.

Poblano peppers can be used in a variety of ways.

They can be enjoyed raw in salsas and other dips, as well as added to chilis, taco meat, or sauces.

To prepare a poblano pepper for these dishes, halve the pepper lengthwise, remove the stem and seeds, and then dice it into pieces.

You can also roast poblano peppers whole and then remove the skin, stem, and seeds.

One of the most popular ways to enjoy poblanos is stuffed with ground meat, beans, rice, spices, corn, and tomatoes.

To make stuffed poblanos, halve the peppers, remove the seeds, and roast them in the oven at 350F (177C) for 1015 minutes.

Stuff each pepper half with filling and sprinkle cheese on top, then put them back in the oven for a few more minutes.

You can enjoy poblano peppers in salsas and tacos, or make stuffed poblanos by filling them with meat, beans, tomatoes, corn, and cheese and baking them in the oven.

Poblano peppers are a mild variety of chili peppers that are highly nutritious and equally delicious.

Theyre rich in vitamins A and C, carotenoids, capsaicin, and other compounds that may act as antioxidants, have anticancer activity, and fight inflammation.

Poblano peppers can be added to soups, tacos, or salsas, or stuffed with meat, beans, rice, and cheese.

Days after shaking hands with German regulators over the launch and coverage of its beta-thalassemia gene therapy, bluebird bio has wooed a Celgene exec to lead its European operations.

Nicola Heffron, a biopharma vet with stints across Eli Lilly, GSK and Shire, jumps from a brief tenure overseeing marketing for Celgenes myeloid portfolio in Summit, NJ. She will now be based in Zug, Switzerland.

Shes replacing Andrew Obenshain as he joins CEO Nick Leschly and the leadership team in Boston, according to Bloomberg, which first reported the news. Obenshains new title is chief of wings.

On Monday bluebird announced that Germany will be the first country to commercially offer Zynteglo, their procedure encoding A-T87Q-globin gene in CD34+ cells extracted from patients. Under their value-based payment scheme, the $1.8 million price is divided into five installments. After an initial payment is made at the time of infusion, the payers wait and see and only pay if the patients continue to be transfusion-free.

Multiple statutory health insurances have signed onto the plan, bluebird said, and University Hospital of Heidelberg will host the first qualified treatment center.

The biotech has been busy sorting out manufacturing specs and talking to individual countries since the EU issued an historic OK last June. Its sanctioned for a specific group of beta-thalassemia patients those who are 12 years and older, transfusion dependent, do not have a 0/0 genotype and for whom hematopoietic stem cell transplantation is appropriate but a donor is not available.

For patients with TDT, lifelong chronic blood transfusions are required in order to survive, bluebird chief commercial officer Alison Finger emphasized in a statement. Their one-time infusion promises to do away with the transfusions for good.

A rolling BLA submission to the FDA has begun, bluebird added.

What happens when you cross stem cells from a frog heart and frog skin? Not muchthat is, until you program those cells to move. In that case, you've created a xenobot, a new type of organism that's part robot, part living thing.

And we've never seen anything like it before.

Researchers from Tufts University, the University of Vermont, and Harvard University have created the first xenobots from frog embryos after designing them with computer algorithms and physically shaping them with surgical precision. The skin-heart embryos are just one millimeter in size, but can accomplish some remarkable things for what they are, like physically squirming toward targets.

"These are novel living machines," Joshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research, said in a press statement. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism."

By studying these curious organisms, researchers hope to learn more about the mysterious world of cellular communication. Plus, these kinds of robo-organisms could possibly be the key to drug delivery in the body or greener environmental cleanup techniques.

"Most technologies are made from steel, concrete, chemicals, and plastics, which degrade over time and can produce harmful ecological and health side effects," the authors note in a research paper published in the scientific journal Proceedings of the National Academy of Sciences. "It would thus be useful to build technologies using self-renewing and biocompatible materials, of which the ideal candidates are living systems themselves."

Xenobots borrow their name from Xenopus laevis, the scientific name for the African clawed frog from which the researchers harvested the stem cells. To create the little organisms, which scoot around a petri dish a bit like water bearsthose tiny microorganisms that are pretty much impossible to killthe researchers scraped living stem cells from frog embryos. These were separated into single cells and left to incubate.

They differentiated the stem cells into two different kinds: heart and skin cells. The heart cells are capable of expanding and contracting, which ultimately aids the xenobot in locomotion, and the skin cells provide structure. Next, using tiny forceps and an even smaller electrode, the scientists cut the cells and joined them together under a microscope in designs that were specified by a computer algorithm.

Interestingly, the two different kinds of cells did merge together well and created xenobots that could explore their watery environment for days or weeks. When flipped like a turtle on its shell, though, they could no longer move.

Other tests showed whole groups of xenobots are capable of moving in circles and pushing small items to a central location all on their own, without intervention. Some were built with holes in the center to reduce drag and the researchers even tried using the hole as a pouch to let the xenobots carry objects. Bongard said it's a step in the right direction for computer-designed organisms that can intelligently deliver drugs in the body.

Sam Kriegman, UVM

While these xenobots are capable of some spontaneous movement, they can't accomplish any coordinated efforts without the help of computers. Really, xenobots couldn't fundamentally exist without designs created through evolutionary algorithms.

Just as natural selection dictates which members of a species live and which die offbased on certain favorable or unfavorable attributes and ultimately influencing the species' characteristicsevolutionary algorithms can help find beneficial structures for the xenobots.

A team of computer scientists created a virtual world for the xenobots and then ran evolutionary algorithms to see which potential designs for the xenobots could help them move or accomplish some other goal. The algorithm looked for xenobots that performed well at those particular tasks while in a given configuration, and then bred those microorganisms with other xenobots that were considered "fit" enough to survive this simulated natural selection.

In the video above, for example, you can see a simulated version of the xenobot, which is capable of forward movement. The final organism takes on a similar shape to this design and is capable of (slowly) getting around. The red and green squares at the bottom of the structure are active cells, in this case the heart stem cells, while the blueish squares represent the passive skin stem cells.

All of this design work was completed over the course of a few months on the Deep Green supercomputer cluster at the University of Vermont. After a few hundred runs of the evolutionary algorithm, the researchers filtered out the most promising designs. Then, biologists at Tufts University assembled the real xenobots in vitro.

Anything dealing with stem cells is bound to meet at least some flack because detractors take issue with the entire premise of using stem cells, which are harvested from developing embryos.

That's compounded with other practical ethics questions, especially relating to safety and testing. For instance, should the organisms have protections similar to animals or humans when we experiment on them? Could we, ourselves, eventually require protection from the artificially produced creatures?

"When youre creating life, you dont have a good sense of what direction its going to take," Nita Farahany, who studies the ethical ramifications of new technologies at Duke University and was not involved in the study, told Smithsonian Magazine. "Any time we try to harness life [we should] recognize its potential to go really poorly."

Michael Levin, a biophysicist and co-author of the study from Tufts University, said that fear of the unknown in this case is not reasonable:

At its heart, the study is a "direct contribution to getting a handle on what people are afraid of, which is unintended consequences," Levin said.

These Are the First Living Robots: Machines Made from Frog Stem Cells - Popular Mechanics

Adult bone repair relies on the activation of bone stem cells, which still remain poorly characterized. Bone stem cells have been found both in the bone marrow and in the outer layer of tissue, called periosteum, that envelopes the bone. Of the two, periosteal stem cells are the least understood.

Having a better understanding of how adult bones heal could reveal new ways of repair fractures faster and help find novel treatments for osteoporosis. Dr. Dongsu Park and his colleagues at Baylor College of Medicine investigate adult bone healing and recently uncovered a new mechanism that has potential therapeutic applications.

Previous studies have shown that bone marrow and periosteal stem cells, although they share many characteristics, also have unique functions and specific regulatory mechanisms, said Park, who is assistant professor of molecular and human genetics and of pathology and immunology at Baylor.

It is known that these two types of bone stem cells comprise a heterogeneous population that can contribute to bone thickness, shaping and fracture repair, but scientists had not been able to distinguish between different subtypes of bone stem cells and study how their different functions are regulated.

In the current study, Park and his colleagues developed a method to identify different subpopulations of periosteal stem cells, define their contribution to bone fracture repair in live mouse models and identify specific factors that regulate their migration and proliferation under physiological conditions.

The researchers discovered specific markers for periosteal stem cells in mice. The markers identified a distinct subset of stem cells that showed to be a part of life-long adult bone regeneration.

We also found that periosteal stem cells respond to mechanical injury by engaging in bone healing, Park said. They are important for healing bone fractures in the adult mice and, interestingly, they contribute more to bone regeneration than bone marrow stem cells do.

In addition, the researchers found that periosteal stem cells also respond to inflammatory molecules called chemokines, which are usually produced during bone injury. In particular, they responded to chemokine CCL5.

Periosteal stem cells have receptors molecules on their cell surface called CCR5 that bind to CCL5, which sends a signal to the cells to migrate toward the injured bone and repair it. Deleting the CCL5 or the CCR5 gene in mouse models resulted in marked defects or delayed healing. When the researchers supplied CCL5 to CCL5-deficient mice, bone healing was accelerated.

The findings suggested potential therapeutic applications. For instance, in individuals with diabetes or osteoporosis in which bone healing is slow and may lead to other complications resulting from limited mobility, accelerating bone healing may reduce hospital stay and improve prognosis.

Our findings contribute to a better understanding of how adult bones heal. We think this is one of the first studies to show that bone stem cells are heterogeneous, and that different subtypes have unique properties regulated by specific mechanisms, Park said. We have identified markers that enable us to tell bone stem cell subtypes apart and study what each subtype contributes to bone health. Understanding how bone stem cell functions are regulated offers the possibility to develop novel therapeutic strategies to treat adult bone injuries.

Regenerative medicine has emerged as new paradigm in human health. It has the potential to resolve unmet medical needs. Rapid growth in the interdisciplinary field of regenerative medicine is altering the health care domain by converting fundamental science into a variety of regenerative technologies. Stem cell is an undifferentiated mass of cell that has the ability to divide indefinite times. It can be further differentiated into specialized cells such as blood cells, skin cells, neurons, heart cells, chondrocytes, and osteocytes under specific conditions. Unspecialized nature, self-renewal capability, and dedifferentiation are the unique features of stem cells. Thus, these cells are useful in different applications in pharmaceutical research and medical fields.

Experts from the Mayo clinic warned that spots on the skin may signal a blood cancer. In connection with what experts suggest as soon as possible to go to the doctor when the symptom of.

Leukemia is a cancer primarily occurs in the bone marrow as a result of mutations in blood stem cell. The consequence is the loss of the descendants of the mutated cells ability to differentiate to Mature blood cells. The danger of the disease is that the symptoms are not specific, often among the signs unexplained weight loss, fever and chills. The experts considered it important to warn you that spots on the skin can indicate cancer of the blood that allows an early identification is a deadly health hazard. Among the other important symptoms of blood cancer: swollen lymph nodes, enlarged liver or spleen, frequent nosebleeds, excessive sweating, especially at night, bone pain, constant fatigue, recurrent infections.

With regard to treatment, the experts from Mayo clinic said: chemotherapy is the main form of treatment. Biological therapy works by using methods that help the immune system to recognize cancer cells and attack them. Among the methods of struggle with a deadly disease and radiation therapy, which destroys leukemia cells and stop their growth. Among the solutions and stem cell transplantation is bone marrow transplantation. The essence of the procedure is that the blood stream is filled with healthy blood cells, which often helps to restore normal functioning of the hematopoietic system.

Also, I think we're all trying to be kinder to the environment with our lifestyle choices, and unlike most sheet masks on the market, it's made with100 per cent natural cotton fibres that will biodegrade six months after use. The packaging itself is recyclable too.

If you've ever watched one of those videos of a baby smiling with glee after they try chocolate for the first time, that was me with chemical exfoliation. Unlike scrubs which use psychical exfoliation to buff away at dead skin, chemical exfoliants like AHAs, glycolic acid and lactic acid dissolve dead skin and sebum which can cause breakouts and dull skin.

And when it comes to products which do just that, this cult-favouritemask is one of my personal picks.

Not only does it kind of smell, and look, like theinside of a pumpkin pie, the wonderful combo of glycolic acid, fruit stem cells, Vitamin C, Manuka honey andantioxidant-rich pumpkin puree works to give you the deliciously radiant skin you crave.

In terms of tingliness, there was less sensation than the CannaCell Glow Mask but the results were equally as impressive. My pores appeared tighter, and the texture of my skin felt smoother, brighter and just... better.

In 2019, Massive Science covered some ground. We wrote about climate change killing off biodiversity, galaxies eating one another, parakeet mate selection, and on and on. We polled the Massive staff for their favorite stories of the year, both in what we worked on and in the outside world. But first, our top five most popular articles of the year:

#5

After another devastating intergovernmental report on wildlife loss, Cassie Freund wrote this urgent call for action. It's the very real end of the world, why isn't anyone acting?

#4

Neuroscience is Massive's bread-and-butter, so Claudia Lopez-Lloreda's story on fish giving up and the brain cells responsible checked a lot of boxes. Next time you quit on something, you'll know who's at fault.

#3

"Unexpected science" is another angle our writers have gotten serious mileage out of, and Darcy Shapiro's article on gorilla teeth, snacks, and how that changes human history is a classic of the genre.

#2

Definitely another "unexpected science" entry, Molly Sargen's story combined math, bridge building, and breakfast food. Now we know our audience likes that and more breakfast food science will be coming in 2020.

#1

It's got it all: space and a vague sex angle. What more could you want? You might say that Mackenzie Thornbury's article went viral. We won't though.

Sometimes though, what we think is cool and what you all think is cool doesn't match up. We're not mad about though, we know disagreement is natural. Not mad at all. Here are our personal faves that we think you should give a second shot. No pressure though!

Or, as it was more affectionately known in the Slack channel: Babies...in...SPAAAAAAACE.

Another Cassie Freund work on the actual human effort to get around conservation efforts that other humans are employing to save the planet.

"Connecting brains" is a sub-genre of our normal neuroscience work and Jordan Harrod wrote one of the best ones we've ever seen.

Yeah, the science is cool, the writing is great, but you know what really spiced up Luyi Cheng's debut article? The gifs.

We love all Our Science Heroes equally, but there's something about du Chtelet. If a man had had her adventurous, influential life that included standing on Newton's shoulders and having Voltaire as a kept man, there'd be movies made about that man's life. This is our pitch for a du Chtelet biopic. Hollywood, please call us.

Cheap, re-purposed cancer drugs, negative carbon-emissions technology, calculating how fast the universe is expandingand huge leaps forward in quantum computing.

Will one of these be the biggest scientific breakthrough of 2020?

We asked a handful of New Zealand's top scientists what "Eureka!" moments might be on the cards next year but even with their formidable combined brain power and expertise, some found it hard to answer and hinted it was difficult to sheet home specific advances to any one year.

And, as one scientist says, 2020's most ground-breaking discovery may come as a total surprise, made accidentally by a student in a lab late one night.

2020's most ground-breaking discovery may come as a total surprise, made accidentally by a student in a lab late one night.

Wellington's Gillies McIndoe Research Institute is carrying out cutting-edge research into ways of treating cancer without radiotherapy, chemotherapy or surgery.

The institute's founder and executive director, Dr Swee Tan, believes significant steps will be made in 2020 towards "re-purposing" existing drugs for cancer treatment.

Tan, a plastic surgeon and medical researcher who has received international recognition for dealing with life-threatening and disfiguring conditions, saiddrugs licensed and marketed for a particular treatment often had other benefits.

"They can be re-purposed for another condition, for the treatment of cancer. This is usually with drugs that have been around for some time they are off-patent, so they become generic, which means they cost next to nothing.

"Another advantage is their safety profile is well understood."

Wellington's Gillies McIndoe Research Institute's founder and executive director, Dr Swee Tan, believes significant steps will be made in 2020 towards "re-purposing" existing drugs for cancer treatment.

Globally, 18 million new cancer cases are diagnosed each year, resulting in nearly 10 million deaths.

"In New Zealand alone, new cancer cases are about 25,000 a year, and on top of that there are 11,000 non-melanoma skin cancers.

"The incidence of cancer is predicted to increase by 50 per cent by 2035, which is just around the corner. We are completely unprepared for that."

The increased incidence of cancer largely bowel, breast, prostate and lung cancers, and melanoma is mostly because people are living longer and due to lifestyle and diet, Tan says.

"Part of the problem now is the expense of treatment. In New Zealand, we spend $1 billion a year to treat cancer, and that is just the fiscal cost, that doesn't count emotional or personal.

"The cost is escalating because of the novel cancer drugsand, at some point, we are not going to be able to afford treatment for cancer.

"This creates disparity in access to treatment because some of these drugs are not funded and, if you have the means, you can buy it, but I don't think that is a good way to run a society. I think a society should allow people to access healthcare, regardless of personal circumstance."

New Zealand is as vulnerable as all countries to the global growth in antimicrobial resistance that is making some diseases untreatable. Dr Siouxsie Wiles, a microbiologist from the University of Auckland, a Royal Society Te Aprangi Councillor and an expert adviser on the report on antimicrobial resistance produced by Royal Society Te Aprangi explains why it is such a big issue for us.

The institute has been undertaking a clinical trial based on drug re-purposing to control cancer stem cells, the proposed origin of cancer.

"It consists of a combination of low-cost, off-patent, oral medications to control cancer stem cells. We believe this would be more effective than using a single drug.

"For the cost of the drug itself, it costs about $4000 a year a patient, compared with the average cancer treatment, which is about $50,000 per patient.

"You have to prove it is effective first. The big issue with drug re-purposing is 'big pharma' is not interested because there is no money in it. The only way that we can realise the potential is for philanthropy and government to support initiatives like this."

Propranolol, a beta-blocker, had been added to the treatment for melanoma and angiosarcoma.

During 2020, GMRI would also be working on treatments for disfiguring keloid scars.

"They can cause quite significant issues with quality of life. They affect about 2 per cent of the general population, but in dark-skinned races, especially from the African continent, incidence can be up to 16 per cent.

"Treatment is really quite unsatisfactory, hence the reason why we are researching a solution. If you do surgery to remove it, almost every single one returns. Sometimes surgery is followed by radiotherapy to prevent recurrence. Topical chemotherapy is also used.

"What we have found is stem cells as the underlying problem. We are doing further work, which may allow us to develop a simpler, more effective, low-cost treatment taken by mouth, or by applying to the keloid lesion directly."

University of Auckland molecular biologist Dr Hilary Sheppard, a specialist in developmental and stem-cell biology, thinks there will be more emphasis next year on the gene-editing of adult cells.

University of Auckland microbiologist,associate professor Siouxsie Wiles, a specialist in infectious diseases and antimicrobial resistance, says there are "desperately" needed breakthroughs in her field next year and beyond, including:

- Rapid "bedside" diagnostic tests that are cheap and can tell the medical practitioner if the patient has a bacterial or viral infection "a bonus if it can tell, if bacterial, what antibiotics would kill the bacterium responsible".

- Effective vaccines for tuberculosis, gonorrhoea, Staphylococcus aureus, Group A and B Streptococci, giardia "I could go on and on".

- Drugs that can kill carbapenemase-producing Enterobacteriaceae "a very scary group of organisms that are becoming untreatable".

"The other breakthroughs we need aren't scientific, they are political," she says.

"[We need] a global agreement on tackling antimicrobial resistance, which would include incentives to bring the pharmaceutical industry back in to antimicrobial development.

"Failing that, nationalisation of pharmaceutical companies so that development of drugs isn't a for-profit initiative."

University of Auckland microbiologist, associate professor Siouxsie Wiles, says a global agreement on tackling antimicrobial resistance is desperately needed.

University of Auckland molecular biologist Dr Hilary Sheppard, a specialist in developmental and stem-cell biology, thinks there will be more emphasis next year on the gene-editing of adult cells.

"We have seen some major breakthroughs this year, such as the versatile tool which allows for gene-editing with increased precision over existing tools so the technique is becoming more reliable and safer. Hopefully, next year, we will see these newer techniques being tested in clinically relevant cells.

"As part of that, I hope we will see a community-wide discussion about the ethics of gene-editing with a particular focus on adult cells. Personally, I do not think we should be editing germline cells or embryos at least not for the next five years, while the ethical issues are debated.

"Part of gene-editing is knowing what DNA sequence needs to be edited, so I think I hope this could be the year where personalised medicine and individual genotyping takes off.

"Our research focuses on patients with a fragile skin condition called epidermolysis bullosa (EB). We are pushing to get patients with EB genotyped so that we can perform gene-editing on their skin cells we can't do anything useful without this information.

"Currently, we are paying for the genotyping out of our research budgets. Of course, genotyping raises its own ethical and societal issues, so I hope we will see more discussion about this."

In 2020, results should start rolling in from clinical trials using edited T-cells against melanoma and edited bone-marrow cells to treat patients with sickle-cell anaemia, Sheppard says.

"These are very exciting times. I'm sure we'll see more clinical trials targeting previously untargeted disorders soon perhaps for conditions like Duchenne muscular dystrophy and cystic fibrosis."

In this podcast, The Detail's Sharon Brettkelly talks to Auckland University physics professor Shaun Hendy about his no-flying mission for the whole of last year.

While Tan, Sheppard and Wiles are looking for discoveries on the tiniest of scales, other scientists are grappling with the biggest question in the universe.

Theoretical cosmologist and University of Auckland professor of physics Richard Easther is among those hoping for a resolution of what has become known as "Hubble tension" a growing disagreement in calculations of how fast the universe is expanding, which has repercussions on its likely age.

The Hubble Constant the number that tells us how fast the universe was expanding has always been hard to measure, he says.

"There was a period of time when a whole different bunch of approaches to measuring it had converged on a single value, which is fascinating. But just over the last couple of years, it seems like there are now two different sets of numbers you get and they've pulled apart a little bit.

"You know, there's this joke that science isn't so much about people saying 'Eureka!' but about someone looking at something and going, 'well, you know, that's funny'.

"This is increasingly resembling one of those moments.

"The numbers are clustering around two values one that would put it in the early to mid-70s [kilometres per second per megaparsec], and one that would put it in the mid- to late 60s, and the uncertainty in the measurements is such that they don't really overlap with each other.

"As the individual measurements get more accurate, the sharpness of the disagreement is growing."

University of Auckland physicist, professor Shaun Hendy, is expecting leaps ahead in clean energy in 2020.

Does it matter? Of course, Easther says.

"There are different physical assumptions that go into the different measurementsandso, if there is a real discrepancy, it would tell us there's something about the expansion of the universe that we don't understand.

"It's hinting at that. The implication seems to be that the story is one step more complicated than current models of the expanding universe might recognise.

"One thought is, that in one set of numbers, there's something that got missed and kind of got away. The other possibility is, there's something kind of physical, that isn't included in our current thinking of the expanding universe.

"The idea that there is something interesting going on is something that cosmologists over the course of the last year have grown substantially more willing to entertain."

Chris Skelton/STUFF

Nicola Gaston is an Associate Professor in the Department of Physics at the University of Auckland and Co-Director of the MacDiarmid Institute for Advanced Materials and Nanotechnology.

At the University of Otago, associate professor Mikkel Andersen, a physicist in the university's Dodd-Walls Centre for Photonic and Quantum Technologies, has been making astounding international discoveries and controlling the movement of individual atoms in a world-first laboratory experiment.

Such control opens up possibilities for a "second quantum technology revolution" and quantum supremacy, something Andersen says will creep closer in 2020.

The first quantum revolution was made possible by the discovery of quantum mechanics in the 1920s, leading to the development of transistors and lasers, the building blocks of all computers.

In the second, he says quantum computers of fewer than 100 atoms will ultimately be able to out-compete "the world's combined conventional computing power".

"Reaching quantum supremacy means that a quantum computer will be able to do calculations that cannot be done on the world's conventional computers. I do not know if it will happen next year, but it will happen eventually.

"In recent years, Google, IBM, Microsoft and a lot of others have invested enormously in development of quantum computers. Quantum supremacy is likely still some years away, but it is one of those things that would clear all the headlines if it happened in 2020."

University of Auckland physicist,professor Shaun Hendy, agrees.

"Google declared quantum supremacy last month they demonstrated that a quantum computer could beat a conventional computer, albeit at a very niche task.

"We'll see more of this next year, as quantum computers start to stretch their legs just don't expect to see one on your phone any time soon."

Ross Giblin

Victoria University of Wellington's professor James Renwick hopes to see breakthroughs in climate change science which reduce greenhouse gas emissions.

Hendy is also expecting leaps ahead in clean energy in 2020.

"We will continue to see the cost of solar and battery technologies fall, to the extent that they will start to disrupt other energy systems. We have seen this already in Australia, where it has become a defining political issue.

"It will play out differently in New Zealand, because our grid is already more than 80 per cent renewable, while many of our industrial energy systems are not. Expect to see some of our big industrial corporates Fonterra, NZ Steel etc moving to greener industrial processes."

Victoria University of Wellington's Professor James Renwick, head of the school of geography, environment and earth sciences, hopes to see breakthroughs in climate change science which reduce greenhouse gas emissions.

He points to work being done at the Cawthron Institute in Nelson into the benefits of using the seaweed Asparagopsis armata as cattle feed. Chemicals in the red seaweed reduce microbes in the stomachs of cattle that make them burp when eating grass.

Renwick is also excited about the use of artificial intelligence (AI) and machine learning to help with severe weather prediction.

"Weather forecasters are totally inundated with information these days, volumes of radar data and satellite data coming through every 10 minutes. So, AI can help in making sense of all that, and what is the most important in determining where, for example, a severe storm will happen."

University of Otago associate professor Mikkel Andersen believes a "second quantum technology revolution" and quantum supremacy will creep closer in 2020.

Auckland University of Technology senior lecturer Dr Mahsa Mohaghegh also foresees huge steps forward in AI and its applications next year and beyond.

"In the medical sector, AI is being used to speed up symptom recognition and diagnosis. Early warning signs can be easily detected, allowing fast reaction.

"Environment and climate monitoring using AI can assist with weather-cycle predictions, frost warnings, and harvest alerts. Automated irrigation is possible using moisture and temperature sensors."

There are also uses in New Zealand's burgeoning space industry, in traffic management and in the "smart home" of the future, she says.

"New Zealand is a leader and frontrunner in the development of AI and related fields. The next 10 years of technology development are set to be exciting."

David White

Auckland University of Technology senior lecturer Dr Mahsa Mohaghegh foresees huge steps forward in AI and its applications next year.

University of Auckland physicist, associate professor Nicola Gaston, co-director of the Victoria University of Wellington-hosted MacDiarmid Institute for Advanced Materials and Nanotechnology, told Stuff scientific discovery did not happen "one year at a time".

"Discoveries that impact on our lives next year will be built on work that has been going on for decades. The biggest discoveries of next year will be the ones that impact on our lives in a decade or two.

"But there is no competition between this fundamental scientific work of discovery and the development of technologies. The two go in tandemand, perhaps in 2020, we can try to appreciate that."

That may be finding a way of moving to negative emissions technologies, or changing the chemistry of materials so they are recyclable and avoid environmental pollution.

"The most important breakthrough of 2020 will be one that none of us sees.

"It'll be a dedicated student or post-doc in a lab somewhere, or up late at night on a computer, who solves the last remaining piece of one of the puzzles that underpin so much of what we hope technology can do for us in the future."

Highlights

Skin stem cells and the mechanism of skin repair: illustrating how skin stem cells are involved in the skin repair process.

Cell products for skin repair: the history of skin repair products and newly emerging medications applying stem cell biology.

Drug reviewing issue of skin cell products: the disputations of dermatological drug development and critical recommendations.

Stem cell products and its clinical applications have been widely discussed in recent years, particularly when the Japanese induced pluripotent stem cells founder Dr. Yamanaka was awarded as Nobel Prize laureate in 2013. For decades, major progresses have been achieved in the stem cell biology field, and more and more evidence showed that skin stem cells are involved in the process of skin repair. Stem/progenitor cells of the epidermis are recognized to play the most essential role in the tissue regeneration of skin. In this review, we first illustrated basic stem cell characteristics and various stem cell subtypes resided in the skin. Second, we provided several literatures to elucidate how stem/progenitor cells collaborate in the process of skin repair with the evidence from animal model studies and invitro experiments. Third, we also introduced several examples of skin cell products on the pharmaceutic market and the ongoing clinical trials aiming for unmet medical difficulties of skin. Last but not least, we summarized general reviewing concerns and some disputatious issues on dermatological cell products. With this concise review, we hope to provide further beneficial suggestions for the development of more effective and safer dermatological stem/progenitor cell products in the future.

Skin Stem Cells Comments Off on Stem cell therapy on skin: Mechanisms, recent advances and … | January 10th, 2020

Cara Gormallys pregnancy was shadowed by grief. As a queer woman wanting to have a baby, the biology professor had figured finding a sperm donor would be the only obstacle she and her partner faced. But thanks to Gormallys organizational skills and love of making lists, the couple landed on a donor with relative ease.

Then, Gormally struggled to conceive. Each month brought fresh disappointment and loss.

So much of the process depended on random, heart-breaking chance, she says. The emotional and financial roller coaster was exhausting.

But it wasnt the hardest part. The couple had accepted that, as much as they wanted a baby, their child wouldnt be biologically related to Gormallys spouse.

I grieved that our child wouldnt be genetically related to both of us, Gormally says. I longed for the biologically impossible.

But now, a new set of technologies have the potential to change whats possible allowing same-sex partners to have kids who share their genetic material, just like straight couples.

In mammals, pretty much every cell in the body carries two sets of genetic material. One set comes from mom and the other from dad. Eggs and sperm are the only exceptions; they have just one set. Then, when a sperm fertilizes an egg, those two sets combine, restoring the usual number to two sets per cell.

Gormally and other same-sex partners are currently barred from their dreams by a phenomenon called genomic imprinting. It uses a distinct tag from each parent to mark the DNA that mammals pass on to their offspring. The process ensures that, for a small percentage of genes, we only express the copy of genetic material provided by our mother or our father. When this imprinting process goes awry, kids can end up with inactive gene regions that cause miscarriages, developmental defects and cancer.

During this genomic imprinting, moms distinct collection of tags typically turns off certain genes, so that just dads copy is expressed. And dad imparts his own marks that leave only the maternal copy on. (Most imprints silence gene expression, but some activate it.) Thats a problem for same-sex couples who want to have a baby. If both sets of an offsprings genes come from maternal DNA, for example, then both copies of imprinted genes will be off. So, the embryo cant make any of the genes products.

We dont get the full set of [gene] products that we need to undergo proper development unless we have both a maternal and paternal contribution to a fertilized egg, says Marisa Bartolomei, a geneticist at the University of Pennsylvania in Philadelphia, who discovered one of the first imprinted genes in mice.

Scientists discovered genomic imprinting in mammals about 30 years ago. During experiments in the mid-1980s, researchers removed either the maternal or paternal genetic contributions from newly fertilized mouse eggs. Then, they transferred in a second set of genes from another mouse to create embryos with either two sets of female genetic material or two sets of male genetic material. A surrogate mouse was able to gestate the embryos, but none survived. The finding showed normal development requires genetic material from both a father and the mother. More than that, the outcomes revealed that maternal and paternal genetic material differ from each other in meaningful ways.

Later experiments revealed mice developed differently depending on whether they happened to receive both copies of certain regions of DNA from one parent (rather than one copy from each parent).

Mice with hairpin-shaped tails were telling examples. When researchers deleted the gene region responsible for a hairpin tail from a mothers genome, mice embryos grew large and died partway through gestation. In contrast, deleting the same region from the paternal genome had no effect on the rodents growth or development.

In the three decades since, researchers have found more imprinted genes (they suspect there are between 100 and 200 such genes) and the molecular tags that silence them. Scientists have also taken strides connecting imprinting defects to developmental disorders in humans. But all along, researchers have known that imprinting prevents same-sex parents from having children.

In October 2018, researchers overcame this impossibility in mice. By deleting imprinted regions, Wei Li and a team at the Chinese Academy of Sciences in Beijing produced healthy mice from two moms. The researchers also created mouse pups from two dads for the first time. However, the offspring died just a few days after birth.

Despite the loss, Li is optimistic. This research shows us what is possible, he says.

To overcome the imprinting barrier, Li and his fellow researchers turned to CRISPR, a gene-editing technique thats made altering genomes easier than ever. They used the tool to delete gene regions from embryonic stem cells from mice mothers. The researchers then injected these modified stem cells into the egg of a female mouse and then used a third surrogate female mouse to carry the fetus to term.

The team had already seen some success two years earlier when they created mouse pups with two genetic mothers by deleting two imprinted regions. Although these bimaternal mice also grew to adulthood and produced pups of their own, they developed growth defects. On average, the bimaternal mice were 20 percent lighter than their hetero-parental counterparts. In their latest study, Li and his team also deleted a third region from the mothers genes, which restored the animals growth to normal.

But the scientists had to clear a few more hurdles to generate mice with two genetic fathers. They found, through a process of trial and error, that they needed to remove twice as many imprinted regions in the bipaternal mice as the bimaternal mice. In total, the team deleted seven imprinted regions to successfully create mice from two dads.

Still, the numbers were not in their favor. Only two and a half percent of embryos made it to term and less than half of one percent lived for two days. None made it to adulthood.

The produced bipaternal mice are not viable, which implies more obstacles are needed to cross to support their postnatal survival, if possible, Li says. The lower birth rate, on the other hand, implies the existence of an unknown barrier hindering the development of bipaternal embryos.

In contrast, the bimaternal mice fared much better. These mice grew to adulthood and were healthy enough to have pups of their own by mating with typical male mice. They also behaved the same as the control mice. As far as the researchers could tell, the bimaternal mice appear as healthy and normal as any other laboratory mice.

It does not mean that they are normal in every aspect, Li cautions. One cannot investigate all the aspects under restricted experimental conditions with a limited number of animals.

Despite the researchers success, Li says the technique is not ready for use in humans. It is never too much to emphasize the risks and the importance of safety before any human experiment, he says, particularly in regard to the bipaternal offspring, which currently are severely abnormal and cannot survive to adulthood.

The bimaternal offspring hold more promise. The team is now working to translate their findings to monkeys. And that work could bring the impossible one step closer to feasible for humans.

Lis research is encouraging but its a long way from helping Gormally and her spouse. However, its also not the only shot for same-sex couples. Another new technology called in vitro gametogenesis, or IVG, may be an alternative potential path for same-sex couples to have their own kids.

Scientists use the technique to make eggs and sperm from other cells in the body. To do so, biologists first reprogram adult skin cells to become stem cells. Then, they stimulate the skin-derived stem cells to develop into eggs or sperm.

Researchers from Japan have now perfected the technique in mice. And in groundbreaking work, Katsuhiko Hayashi and Mitinori Saitou and their team generated functional eggs from mice tail cells.

The researchers then fertilized the eggs with sperm from male mice and implanted the embryos into surrogate mothers. The offspring grew up healthy and fertile. In principle, this approach could allow a womans skin cells to be engineered into sperm and used to fertilize her partners egg.

IVG could transform same-sex couples ability to have their own children. If it had been possible at the time, we definitely wouldve have tried to do it, says Gormally, who is now a proud parent to a toddler thanks to her and her spouses sperm donor. [Its] a total game-changer.
