The Future of Stem Cells: Opportunities at the Cutting Edge of Science
By raymumme
Stem cell technology representsone of the most fascinating and controversial medical advances of the past several decades. By now the enormous controversy which surrounded the use of federal funds to conduct scientific research on human stem cells during the George W. Bush administration has largely blown over. Five years have passed since President Obama lifted federal funding restrictions, and amazing progress has already been made in the field.
One can make a good case for stem cells being the most fascinating and versatile cells in the human body. This is precisely due to their stem role. In their most basic form, theyre capable of both replicating themselves an unlimited number of times and differentiating themselvesinto a huge number of other cell types. Muscle cells, brain cells, organ cells, and many others can all be created from stem cells. If youre interested, the NIH has an awesome introductionon stem cells on their website.
The question which has arisen since the discovery of thisamazing cell type has been how to harness their power and versatility. This is the primary focus of research today: how can we precisely control stem cells to perform whatever tasks we need them to do? Of course, other important issues, such as figuring out thebest places from which to harvest stem cells,exist.
Because of their role in the body, the number of potential applications for stem cells are truly stunning. From building custom cell clusters with 3D printers to curing a variety of diseases through bone marrow transplants, growingorgans for transplants, andeven growing edible meat, research is progressing at a frantic pace.
There are two particular areas of research which seem to hold the greatest promise at this point. The first is organs. Anyone who has ever been involved in an organ transplant knows how incredibly complex and difficult the process is. But difficulties like finding the right donor, preserving the organ, and finding enough supply to meet the incredible demand could all be overcome if we could simply use stem cells to grow a custom organ for each transplant from scratch.
Besides this perhaps science-fiction-sounding process of growing organs, theres also incredible excitement surrounding the potential of bone marrow transplants to cure diseases like HIVand Leukemia. This is done by implanting stem cells containing genetic mutations which confer immunity to a variety of diseases into a patients bone marrow, where they can begin naturally replicating and affecting the immune system.
Thisprocedurealso covers transplants designed simply to reintroduce healthy stem cells to help tackle a wider variety of ailments. Often, referred to as regenerative medicine as itinvolves stimulating the bodys preexisting repair mechanisms to help the healing process,thisprocedurealso offer great promise.
Naturally, the speed at which advances are being made in the field has led to problems as well. One recent well-publicized study which seemed to point to the possibility of achieving stimulus-triggered acquisition of pluripotency (essentially demonstrating a new type of stem cells) is now believedto have beenfraudulent.

New Rochelle, NY, January 12, 2014--A promising new therapeutic approach to treat a variety of diseases involves taking a patient's own cells, turning them into stem cells, and then deriving targeted cell types such as muscle or nerve cells to return to the patient to repair damaged tissues and organs. But the clinical effectiveness of these stem cells has only been modest, which may be due to the advanced age of the patients or the effects of chronic diseases such as diabetes and cardiovascular disease, according to a probing Review article published in BioResearch Open Access, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers . The article is available on the BioResearch Open Access website.
Anastasia Yu. Efimenko, TN Kochegura, ZA Akopyan, and YV Parfyonova, Moscow State University (Russia), analyze how aging and chronic diseases might affect the regenerative potential of autologous stem cells and explain the differences between the promising results reported in preclinical studies using stem cells derived from healthy young donors and the more modest success of clinical studies in aged patients. The authors propose strategies to test for and enhance to regenerative properties and therapeutic potential of stem cells in the article "Autologous Stem Cell Therapy: How Aging and Chronic Diseases Affect Stem and Progenitor Cells".
"This review discusses a very important issue in regenerative medicine, how aging and chronic pathologies such as cardiovascular diseases and metabolic disorders affect adult stem/progenitor cells," says BioResearch Open Access Editor Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland. "Future therapies are discussed by the authors in terms of overcoming or correcting the limitations of these cells in order to enhance their therapeutic potential."

MEN Comment: Join Jason Manford in donating to Anthony Nolan donor scheme
By Dr. Matthew Watson
Proud new dad Jason Manford has shared his baby joy over the weekend after welcoming his fifth child into the world.
But the birth has also given the comic and his girlfriend Lucy the opportunity to save a life.
The couple decided to take the unusual step of donating the umbilical cord and placenta to the Anthony Nolan Trust after meeting its team at St Marys Hospital.
The charity helps people with blood cancers matching them with donors if they need a stem cell, bone marrow or cord blood transplant.
It runs an umbilical cord and placenta collection programme in eight hospitals across the country, including St Marys.
Specialists collect the umbilical cord and placenta from donors after the birth and, instead of throwing them away, extract blood from them.
Stem cells in cord blood are adaptable which makes finding matches for donors easier and, as they are stored in a bank, they are available straight away.
Its a fantastic scheme and Jason has done a great service by raising awareness of it. Wed encourage any expecting parents to follow in his footsteps and find out more.

Bedford clinic seeks stem cell match for man with leukemia
By raymumme
If youre between 17 and 35 years old, you may be able to save Chris LeBruns life.
LeBrun, 48, was diagnosed with leukemia last May. The accountant and father of two learned last fall that he needs a stem cell donation to beat the disease.
But the donor cant be just anyone. It has to be someone who is a match for the genetic markers in the proteins of LeBruns white blood cells.
That sounds complicated, but the test to find a genetic match is quite simple. Just by swiping the inside of the mouth with a cotton swab, enough cells are collected to determine whether a match has been found.
Donors between 17 and 35 are accepted, and males are preferred, as transplants from men tend to be more successful.
On Saturday in Bedford, 36 people joined the stem cell registry through Canadian Blood Services to try to help LeBrun and others with certain forms of cancer, bone marrow deficiency diseases, anemia and other immune system and metabolic disorders.
LeBrun lives in Cambridge, Ont., but has deep ties to Nova Scotia, says his longtime friend, Barb Leighton.
Leighton describes her friend as a community leader who volunteers tirelessly for causes that are important to him.
Hes very quiet, very humble, very modest, not at all for attention. Complete, pure altruism, she says.
It seems that LeBruns community spirit runs in the family. His great-uncle, Gerald LeBrun, was a well-regarded Bedford doctor who regularly made house calls long after that practice fell out of fashion. Saturdays stem cell clinic was held at the LeBrun Recreation Centre, which was named after the doctor.

Bedford clinic seeks stem cell match for man with leukemia
By NEVAGiles23
The first bone marrow donors inspired by toddler Margot Martini have donated their stem cells.
Margot, who lost her battle with leukaemia last year after a worldwide search for a donor, inspired thousands of people in the UK to join the stem cell register.
The two-year-old's father, Yaser, has just learnt the donor drive has now flagged up its first two matches with people in need of bone marrow donation.
Mr Martini said: "The response to Margots donor appeal saw more than 35,000 people joined the UK register as potential stem cell donors. As a result, statistically this means that over the next 10 years, more than 500 people will now have the option of a potentially life saving bone marrow transplant.
"Delete Blood Cancer UK inform us that the first of the Team Margot registrants has actually donated their stem cells to a patient in need, which heralds Margots legacy.
"And it gets better: the second Team Margot donor is scheduled to give bone marrow later this month.
"Thank you so much to everyone who has registered and to all those who are encouraging just one more to do the same."
Margot's mother Vicki grew up in Essington and has family across Wolverhampton.

Skin cancer: New mechanism involved in tumor initiation, growth and progression
By Sykes24Tracey
Squamous cell carcinoma (SCC) represents the second most frequent skin cancer with more than half million new patients affected every year in the world. Cancer stem cells (CSCs) are a population of cancer cells that have been described in many different cancers, including skin SCCs and that feed tumor growth, could be resistant to therapy thus being responsible for tumor relapse after therapy. However, still very little is known about the mechanisms that regulate CSCs functions.
In a new study published and making the cover of Cell Stem Cell, researchers led by Pr. Cdric Blanpain, MD/PhD, professor and WELBIO investigator at the IRIBHM, Universit libre de Bruxelles, Belgium, report the mechanisms regulating the different functions of Twist1 controlling skin tumour initiation, cancer stem cell function and tumor progression.
Benjamin Beck and colleagues used state of the art genetic mouse models to dissect, the functional role and molecular mechanisms by which Twist1 controls tumor initiation, cancer stem cell function and tumor progression. In collaboration with Dr Sandrine Rorive and Pr Isabelle Salmon from the department of Pathology at the Erasme Hospital, ULB and the group of Jean-Christophe Marine (VIB, KUL Leuven), they demonstrated that while Twist1 is not expressed in the normal skin, Twist1 deletion prevents skin cancer formation demonstrating the essential role of Twist1 during tumorigenesis. "It was really surprising to observe the essential role of Twist1 at the earliest step of tumor formation, as Twist1 was thought to stimulate tumor progression and metastasis" comments Benjamin Beck, the first author of this study.
The authors demonstrate that different levels of Twist1 are necessary for tumor initiation and progression. Low level of Twist1 is required for the initiation of benign tumors, while higher level of Twist1 is necessary for tumor progression. They also demonstrate that Twist1 is essential for tumor maintenance and the regulation of cancer stem cell function. The researchers also uncovered that the different functions of Twist1 are regulated by different molecular mechanisms, and identified a p53 independent role of Twist1 in regulating cancer stem cell functions.
In conclusion, this work shows that Twist1, a well-known regulator of tumor progression, is necessary for tumor initiation, regulation of cancer stem cell function and malignant progression. "It was really interesting to see that different levels of Twist1 are required to carry out these different tumor functions and that these different Twist1 functions are regulated by different molecular pathways. Given the diversity of cancers expressing Twist1, the identification of the different mechanisms controlled by Twist1 are likely to be relevant for other cancers" comments Cdric Blanpain, the last and corresponding author of this study.

Skin cancer: New mechanism involved in tumor initiation, growth and progression
Quadriplegic veteran to receive stem cell treatments
By raymumme
LAWTON, Okla._A stem cell surgery procedure, not yet approved by the FDA, could give a local paralyzed veteran the use of his arms again.
Two years ago, retired Senior Airman Ted "TJ" Williams was left as a quadriplegic when his Humvee rolled over in a freak accident while on duty in Montana. He spent several weeks in a coma.
Now, he and his wife have found a surgery that may improve his physical abilities. They're dipping into their funds to pay for the procedure, since it's not covered by insurance, but they've set up a GoFundMe account to raise $7,500 to cover travel expenses out of the country to get the treatment.
Williams is able to move his left wrist and arm more, and has even gained more core control, thanks to therapy. But, he still needs his wife's help for simple tasks like getting dressed and using the restroom.
Williams sits next to his wife in his wheelchair and watches TV. Years ago, he would've been running outside, but one accident changed everything.
"I just remember leaving base and then waking up 2 or 3 weeks later, wondering where am I. I couldn't move anything. It was just shocking seeing my family around my bed. I was just like, Wow. What's going on,'" recalled Williams.
On November 29, 2012, Williams was on duty with his security forces team. He was in the back seat when his Humvee suddenly swerved to miss a herd of deer, rolling several times. He was ejected from the vehicle and was later found 60 feet away.
Williams was rushed to the hospital. When he woke up from the coma, doctors told him he had broken the vertebrae in his neck and lost function from the chest down.
"I was really upset and scared. Me and my wife are young. We haven't had children yet or anything. It scared me not knowing what the future was to hold," said Williams.
He was sent to a VA hospital in San Antonio for in-patient rehab. Once he was finished, he met a physical trainer in who specializes in exercises for those who are suffering from spinal cord and other neurological injuries, which was just what he needed.

Quadriplegic veteran to receive stem cell treatments
Bacteria could contribute to development of wound-induced skin cancer
By JoanneRUSSELL25
Researchers at King's College London have identified a new mechanism by which skin damage triggers the formation of tumours, which could have important therapeutic implications for patients suffering with chronic ulcers or skin blistering diseases.
The study, published today in Nature Communications, highlights an innate sensing of bacteria by immune cells in the formation of skin tumours. This molecular process could tip the balance between normal wound repair and tumour formation in some patients, according to researchers.
Although an association between tissue damage, chronic inflammation and cancer is well established, little is known about the underlying cause. Epidermolysis Bullosa (EB), for instance, is one of several rare inherited skin conditions associated with chronic wounding and increased risk of tumours.
However, this study - funded primarily by the Medical Research Council (MRC) and the Wellcome Trust - is the first to demonstrate that bacteria present on the skin can contribute to the development of skin tumours.
Researchers found that when mice with chronic skin inflammation are wounded they develop tumours at the wound site, with cells of the immune system required for this process to take place. They discovered that the underlying signalling mechanism involves a bacterial protein, flagellin, which is recognised by a receptor (Toll-like receptor 5) on the surface of the immune cells.
Although the direct relevance to human tumours is yet to be tested, researchers have shown that a protein called HMGB1 - found to be highly expressed in mice with chronic skin inflammation - is increased in human patients with Epidermolysis Bullosa (EB). The study found a reduction in HMGB1 levels in mice when the TLR-5 receptor was removed from immune cells. This raises the possibility of future treatments aimed at reducing levels of the flagellin bacterial protein on the skin surface, or targeting the TLR-5 receptor.
Professor Fiona Watt, lead author and Director of the Centre for Stem Cells and Regenerative Medicine at King's College London, said: 'These findings have broad implications for various types of cancers and in particular for the treatment of tumours that arise in patients suffering from chronic ulcers or skin blistering diseases.
'In the context of chronic skin inflammation, the activity of a particular receptor in white blood cells, TLR-5, could tip the balance between normal wound repair and tumour formation.'
Professor Watt added: 'Our findings raise the possibility that the use of specific antibiotics targeting bacteria in wound-induced malignancies might present an interesting clinical avenue.'

CSU research on horse injuries, stem-cell recovery, may help humans
By raymumme
Doctors, nurses and anesthesiologist's care for a horse that will be receiving stem cells to help repair a meniscal tear in the stifle at the CSU Veterinary Teaching Hospital in Fort Collins. (Joe Amon, The Denver Post)
Stem-cell research by Colorado State University staffers using bone marrow from horses to heal joint injuries on the same animal is making strides, and researchers have great hope that the project will lead to human medical applications.
A team with CSU's Equine Orthopaedic Research Center reports that adding stem-cell therapy to traditional arthroscopic surgery on horses has significantly increased success rates.
Horses that had follow-up, stem-cell treatment were twice as likely to return to normal activity as those that did not, said David Frisbie, an associate professor of equine surgery with CSU and part of the research team.
"We've doubled it, conservatively," in treating cartilage damage in the knee, Frisbie said.
The team had results of its work published last year in the journal Veterinary Surgery.
Some lesions in the meniscus of horses that could not be treated by surgery have been successfully mended using stem cells alone.
"Western performance horses, reining and cutting horses, and barrel horses are very prone to meniscal injuries," Frisbie said.
Beyond meniscus damage, researchers also have focused on tendon lesions in the lower leg, which typically strike race horses.
Horses that suffered a tendon lesion had about a 66 percent chance of reinjury after surgery. Add stem-cell treatment and the reinjury rate drops to 21 percent, Frisbie said.

Circadian rhythms regulate skin stem cell metabolism and expansion, study finds
By NEVAGiles23
UC Irvine scientists studying the role of circadian rhythms in skin stem cells found that this clock plays a key role in coordinating daily metabolic cycles and cell division.
Their research, which appears Jan. 6 in Cell Reports, shows for the first time how the body's intrinsic day-night cycles protect and nurture stem cell differentiation. Furthermore, this work offers novel insights into a mechanism whereby an out of synch circadian clock can contribute to accelerated skin aging and cancers.
Bogi Andersen, professor of biological chemistry and medicine, and Enrico Gratton, professor of biomedical engineering, focused their efforts on the epidermis, the outermost protective layer of the skin that is maintained and healed by long-lived stem cells.
While the role of the circadian clock in processes such as sleep, feeding behavior and metabolism linked to feeding and fasting are well known, much less is known about whether the circadian clock also regulates stem cell function.
The researchers used novel two-photon excitation and fluorescence lifetime imaging microscopy in Laboratory of Fluorescence Dynamics in UCI's Department of Biomedical Engineering to make sensitive and quantitative measurements of the metabolic state of single cells within the native microenvironment of living tissue.
They discovered that the circadian clock regulates one form of intermediary metabolism in these stem cells, referred to as oxidative phosphorylation. This type of metabolism creates oxygen radicals that can damage DNA and other components of the cell. In fact, one theory of aging posits that aging is caused by the accumulative damage from metabolism-generated oxygen radicals in stem cells.
The Andersen-Gratton study also revealed that the circadian clock within stem cells shifts the timing of cell division such that the stages of the cell division cycle that are most sensitive to DNA damage are avoided during times of maximum oxidative phosphorylation.
Other studies in animals have linked aging to disruption of circadian rhythms, and Andersen said that accelerated aging could be caused by asynchrony in the metabolism and cell proliferation cycles in stem cells.
"Our studies were conducted in mice, but the greater implication of the work relates to the fact that circadian disruption is very common in modern society, and one consequence of such disruption could be abnormal function of stem cells and accelerated aging," he said.
Andersen adds that it is possible that future studies could advance therapeutic insights from this research.

Gamida Cell's NiCord gets FDA and EMA orphan drug status
By JoanneRUSSELL25
Published 07 January 2015
Gamida Cell, a leader in cell therapy technologies and products for transplantation and adaptive immune therapy, announced that orphan drug designation has been granted by The US Department of Health and Human Services, The FDA Office of Orphan Products Development (OOPD) for the investigational medicinal product NiCord for the treatment of acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin lymphoma and myelodysplastic syndrome (MDS).
The FDA orphan drug designation coincides with the positive opinion of the European Medicines Agency's (EMA's) Committee for Orphan Medicinal Products (COMP) regarding NiCord as a treatment for AML. Gamida Cell intends to file for NiCord orphan drug status with the EMA for other indications as well.
"Receipt of orphan drug status for NiCord in the US and Europe advances Gamida Cell's commercialization plans a major step further, as both afford significant advantages. We very much appreciate the positive feedback and support of the FDA and EMA and look forward to continuing what has been a very positive dialogue with these important agencies," said Gamida Cell president and CEO Dr. Yael Margolin.
The FDA and EMA grant an orphan drug designation to promote the development of products that demonstrate promise for the treatment of rare diseases or conditions. Orphan drug designation provides for various regulatory and economic benefits, including seven years of market exclusivity in the U.S. and 10 years in the EU.
NiCord is derived from a single cord blood unit which has been expanded in culture and enriched with stem cells using Gamida Cell's proprietary NAM technology.
It is currently being tested in a Phase I/II study as an investigational therapeutic treatment for hematological malignancies such as leukemia and lymphoma. In this study, NiCord is being used as the sole stem cell source.

Stem Cell Treatment for Spinal Cord Injuries SCI Therapy
By JoanneRUSSELL25
Stem Cell Therapy for Spinal Cord Injuries
SCI or Spinal cord injuries usually occur with a sudden & traumatic injury or blow to the spinal cord that dislocates or fractures the vertebrae. The damage of SCI begins at the point of impact when the displaced disc material,bone fragments, or ligaments either bruise or tear the spinal cord tissue. Most SCI injuries do not sever the spinal cord completely. The SCI is likely to cause minor compressions or fractures of the vertebrae, that crush and destroy the signal carriers called axons. Axons carry electric signals up and down our spinal cords and act as a messenger between our brains and the rest of our bodies. SCI generally cause damage to some,many, or in some cases all the axons.
Some SCI victims can accomplish a complete recovery. Others however,will be left with complete paralysis.SCI are classified in two categories, complete or incomplete. A complete SCI is indicated by the total lack of all sensory and motor functions below the area of injury. An incomplete SCI means that the patient has the ability to convey some messages to &/or from the brain but often in a limited capacity. Most People with incomplete SCI injuries can retain minor sensory and/or motor function below the point of injury. Those who survive SCI will most likely suffer for medical complications like bowel and bladder dysfunction and often have chronic pain. Partial SCI patients also have an increased susceptibility to heart & respiratory problems. Successful recovery usingstem cells to treatspinal cord Injuries depends largely on how well systematic failures and chronic conditions are handled day-to-day.
Cell Therapy for injured Spinal Cordsfocuses on regeneration of the connections between your brain and body that have been broken or severely hampered. Stem cellscan help regain motor functions and regain bowel and bladder dysfunction, regain loss of sensations, help minimize chronic pain,cramps and its associated depression. Conventional treatments for SCI today are focused mainly on providing rehabilitation and the prevention of secondary damage. Recent advancements in spinal cord cell treatments offer hope for thousands of victims around the world who are often left with little or no hope for recovery. Stemcell treatments for spinal cord injury can help support and promote the bodies natural regeneration cycle by stimulating the rapid repair of damaged cells and tissue. The regenerative treatmentgoes well beyond the traditional approach of symptomatic treatments and can help you improve and regain some of the previously lost or impaired physical functions. Cell death normally occurs when our cells are injured. These dead cells are surrounded by both damaged and healthy cells. Stem cells stimulate the healing of these injured cells via the secretion of cytokines and other cells such as NGF or nerve growth factors to trigger the body into self-healing mode.
Thai Medical offers a uniquespinal cordtreatment protocol usinga multi-pronged approach. First, adult stem cells are injected directly into the damaged areas of the spine via the accuracy and precision guidance of a CT-guided intra-spinal injection. The treatment is then supplemented even further with another injection using an LP or lumbar puncture and/or IV drip injections.
CT-guided intra-spinal stem cell treatments are considered the gold standard in the field of Stem Cell treatment for spinal cord injury and spinal injury stem cell research for Stem Cell Treatments in Thailand. The precision of CT guidance allows the neurosurgeon to precisely aim the stem cells inside the healthy spinal cord tissues directly adjacent to the injury and lesions. The CT-guided intra-spinal stem cell treatments avoids the requirements of open spine surgeries of yesteryear. CT-guided intra-spinal stem cell treatments also avoid the risks, pain and subsequent healing time associated with cell treatment for SCI (spinal cord injury.)
The objectives of the enrichedcell treatments for spinal cord injuries is to help repair the injured areas on the cellular level near the point of impacts and lesions. The resulting therapy will generally lead to improved quality of life and improved symptoms primarily in physical function,movements and abilities. The majority of patients who are accepted into the program have show dramatic improvements usually after the first or second treatments and continue to improve and regenerate 6 months to a year after treatment. The results are permanent barring new injuries.

Stem Cell Treatment for Spinal Cord Injuries SCI Therapy
Cord Blood Banking Leader, Cryo-Cell International, Continues to Support the Advancement of Regenerative Medicine
By Sykes24Tracey
Tampa, FL (PRWEB) January 06, 2015
One million Americans experience acute myocardial infarctions, commonly known as a heart attack, each year and of those, approximately 300,000 to 500,000 individuals develop heart failure. A heart attack occurs when blood stops flowing properly to a part of the heart and the heart muscle is injured and can die because it is not receiving enough oxygen.
Cryo-Cell International has agreed to provide the Center with cord blood collections that have previously been donated to Cryo-Cell International by parents and designated for research use to advance regenerative medicine. These cord blood collections will allow the Centers scientists to continue to investigate the mechanisms whereby stem cells can be beneficial in limiting damage from heart attacks. A team at the Center, led by researcher and cardiology specialist, Robert J. Henning, M.D., has demonstrated in research animals that stem cells obtained from human umbilical cord blood can release a large number of biologically active growth factors and anti-inflammatory chemicals that can limit the substantial heart inflammation, cell injury and cell destruction that occurs with acute heart attacks, significantly reducing the effects of heart attacks, even when administered up to 24 hours after the heart attack.
We are making good progress in our studies thanks to the cord blood stem cells contributed by Cryo-Cell International, reports Henning.
Cryo-Cell International and others have demonstrated that human umbilical cord blood stem cells can be preserved for more than 20 years without loss of cell viability or potency. Consequently, parents who have the foresight to use cord blood banking services upon their babys birth can potentially use these cord blood stem cells years later to provide a regenerative treatment for a family member if an acute heart attack occurs. The Centers scientists hope to bring umbilical cord blood stem cell therapy to the treatment of patients who have experienced heart attacks within the next five years.
Heart disease is still the number one leading cause of death in the United States. We feel very fortunate that we can provide a valuable and consistent source of cord blood banked stem cells to the Center for Cardiovascular Research, said David Portnoy, Chairman and Co-CEO of Cryo-Cell International.
About Cryo-Cell International
Founded in 1989, Cryo-Cell International, Inc. is the world's first and most highly accredited private cord blood bank. More than 500,000 parents from 87 countries trust Cryo-Cell International to preserve their family members' stem cells.

Bogi Andersen, professor of biological chemistry and medicine, and Enrico Gratton, professor of biomedical engineering, focused their efforts on the epidermis, the outermost protective layer of the skin that is maintained and healed by long-lived stem cells.
While the role of the circadian clock in processes such as sleep, feeding behavior and metabolism linked to feeding and fasting are well known, much less is known about whether the circadian clock also regulates stem cell function.
The researchers used novel two-photon excitation and fluorescence lifetime imaging microscopy in Laboratory of Fluorescence Dynamics in UCI's Department of Biomedical Engineering to make sensitive and quantitative measurements of the metabolic state of single cells within the native microenvironment of living tissue.
They discovered that the circadian clock regulates one form of intermediary metabolism in these stem cells, referred to as oxidative phosphorylation. This type of metabolism creates oxygen radicals that can damage DNA and other components of the cell. In fact, one theory of aging posits that aging is caused by the accumulative damage from metabolism-generated oxygen radicals in stem cells.
The Andersen-Gratton study also revealed that the circadian clock within stem cells shifts the timing of cell division such that the stages of the cell division cycle that are most sensitive to DNA damage are avoided during times of maximum oxidative phosphorylation.
Other studies in animals have linked aging to disruption of circadian rhythms, and Andersen said that accelerated aging could be caused by asynchrony in the metabolism and cell proliferation cycles in stem cells.
"Our studies were conducted in mice, but the greater implication of the work relates to the fact that circadian disruption is very common in modern society, and one consequence of such disruption could be abnormal function of stem cells and accelerated aging," he said.

Health Beat: Stem cells: A weapon for Huntington's?
By Sykes24Tracey
SAN FRANCISCO -
Mike Hinshaw and Katie Jackson have been a couple since college, but they've known each other much longer.
"We've been together forever. I've actually known Mike since I was five years old," Jackson said.
A marriage and three kids later, they've been through good times and bad. The worst came nine years ago when Hinshaw found out he had Huntington's disease.
"My father had it. He died from it," Hinshaw explained.
Huntington's causes uncontrollable movements and mental decline. There's no cure.
"Unfortunately, it ends in death. It's a fatal disease," said Dr. Vicki Wheelock, neurologist, health sciences clinical professor of neurology and director of HDSA Center of Excellence at UC Davis.
Now, researchers are gearing up for a new trial in humans. Patients will have special bone marrow stem cells injected directly into their brains.
"We've engineered them to make a growth factor that's like a fertilizer for the neurons," said Dr. Jan Nolta, professor and director of the Institute for Regenerative Cures at UC Davis.
That growth factor, BDNF, restored healthy brain cells and reduced behavior deficits in mice. Researchers hope the stem cells will also be the answer to slowing the disease in humans.

'CRISPR' science: Newer genome editing tool shows promise in engineering human stem cells
By Sykes24Tracey

A powerful "genome editing" technology known as CRISPR has been used by researchers since 2012 to trim, disrupt, replace or add to sequences of an organism's DNA. Now, scientists at Johns Hopkins Medicine have shown that the system also precisely and efficiently alters human stem cells.
In a recent online report on the work in Molecular Therapy, the Johns Hopkins team says the findings could streamline and speed efforts to modify and tailor human-induced pluripotent stem cells (iPSCs) for use as treatments or in the development of model systems to study diseases and test drugs.
"Stem cell technology is quickly advancing, and we think that the days when we can use iPSCs for human therapy aren't that far away," says Zhaohui Ye, Ph.D., an instructor of medicine at the Johns Hopkins University School of Medicine. "This is one of the first studies to detail the use of CRISPR in human iPSCs, showcasing its potential in these cells."
CRISPR originated from a microbial immune system that contains DNA segments known as clustered regularly interspaced short palindromic repeats. The engineered editing system makes use of an enzyme that nicks together DNA with a piece of small RNA that guides the tool to where researchers want to introduce cuts or other changes in the genome.
Previous research has shown that CRISPR can generate genomic changes or mutations through these interventions far more efficiently than other gene editing techniques, such as TALEN, short for transcription activator-like effector nuclease.
Despite CRISPR's advantages, a recent study suggested that it might also produce a large number of "off-target" effects in human cancer cell lines, specifically modification of genes that researchers didn't mean to change.
To see if this unwanted effect occurred in other human cell types, Ye; Linzhao Cheng, Ph.D., a professor of medicine and oncology in the Johns Hopkins University School of Medicine; and their colleagues pitted CRISPR against TALEN in human iPSCs, adult cells reprogrammed to act like embryonic stem cells. Human iPSCs have already shown enormous promise for treating and studying disease.
The researchers compared the ability of both genome editing systems to either cut out pieces of known genes in iPSCs or cut out a piece of these genes and replace it with another. As model genes, the researchers used JAK2, a gene that when mutated causes a bone marrow disorder known as polycythemia vera; SERPINA1, a gene that when mutated causes alpha1-antitrypsin deficiency, an inherited disorder that may cause lung and liver disease; and AAVS1, a gene that's been recently discovered to be a "safe harbor" in the human genome for inserting foreign genes.
Their comparison found that when simply cutting out portions of genes, the CRISPR system was significantly more efficient than TALEN in all three gene systems, inducing up to 100 times more cuts. However, when using these genome editing tools for replacing portions of the genes, such as the disease-causing mutations in JAK2 and SERPINA1 genes, CRISPR and TALEN showed about the same efficiency in patient-derived iPSCs, the researchers report.

Scientists Develop Pioneering Method to Define Stages of Stem Cell Reprogramming

Newswise In a groundbreaking study that provides scientists with a critical new understanding of stem cell development and its role in disease, UCLA researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research led by Dr. Kathrin Plath, professor of biological chemistry, have established a first-of-its-kind methodology that defines the unique stages by which specialized cells are reprogrammed into stem cells that resemble those found in the embryo.
The study was published online ahead of print in the journal Cell.
Induced pluripotent stem cells (known as iPSCs) are similar to human embryonic stem cells in that both cell types have the unique ability to self-renew and have the flexibility to become any cell in the human body. iPSC cells, however, are generated by reprogramming skin or blood cells and do not require an embryo.
Reprogramming is a long process (about one to two weeks) and largely inefficient, with typically less than one percent of the primary skin or blood cells successfully completing the journey to becoming an iPSC. The exact stages a cell goes through during the reprogramming process are also not well understood. This knowledge is important, as iPSCs hold great promise in the field of regenerative medicine, as they can provide a single source of patient-specific cells to replace those lost to injury or disease. They can also be used to create novel disease models from which new drugs and therapies can be developed.
This research has broad impact, because by deepening our understanding of cell reprogramming we have the potential to improve disease modeling and the generation of better sources of patient-specific specialized cells suitable for replacement therapy, said Plath. This can ultimately benefit patients with new and better treatments for a wide range of diseases.
Drs. Vincent Pasque and Jason Tchieu, postdoctoral fellows in the lab of Dr. Plath and co-first authors of the study, developed a roadmap of the reprogramming process using detailed time-course analyses. They induced the reprogramming of skin cells into iPSC, then observed and analyzed on a daily basis or every other day the process of transformation at the single-cell level. The data were collected and recorded over a period of up to two weeks.
Plaths team found that the changes that happen in cells during reprogramming occur in a sequential stage-by-stage manner, and that importantly, the stages were the same across all the different reprogramming systems and different cell types analyzed.
The exact stage of reprogramming of any cell can now be determined, said Pasque. This study signals a big change in thinking, because it provides simple and efficient tools for scientists to study stem cell creation in a stage-by-stage manner. Most studies to date ignore the stages of reprogramming, but we can now seek to better understand the entire process on both a macro and micro level.

Plath's team further discovered that the stages of reprogramming to iPSC are different from what was expected. They found that it is not simply the reversed sequence of stages of embryo development. Some steps are reversed in the expected order; others do not actually happen in the exact reverse order and resist a change until late during reprogramming to iPSCs.
"This reflects how cells do not like to change from one specialized cell type to another and resist a change in cell identity," said Pasque. "Resistance to reprogramming also helps to explain why reprogramming takes place only in a very small proportion of the starting cells."
