Qatar- HMC to introduce regenerative therapy to treat foot and ankle illnesses – MENAFN.COM
By daniellenierenberg
(MENAFN - Gulf Times) The Foot and Ankle sub-specialty at Hamad General Hospital (HGH), part of Hamad Medical Corporation (HMC), will soon introduce the latest medical procedure, BMAC, to treat various illnesses related to foot and ankle.'Bone marrow aspirate concentrate (BMAC) is a regenerative therapy procedure that uses stem cells from a patient's bone marrow to initiate healing for a number of orthopaedic conditions, such as tendinopathy, osteoarthritis and cartilage injuries, said Dr Mohamed Maged Mekhaimar, senior consultant and orthopaedic surgeon at HGH.'This will help treating patients with tendon inflation. It can also be used to treat inflammation on the bottom of the foot as well as for traumatic conditions of the ankle. These services will soon be available at Hamad General Hospital, explained Dr Mekhaimar.Foot and ankle services were started at HGH in 2012. 'Now, there is a great demand for these services in the country as more and more people are approaching us for various issues. The centre provides treatment for several problems such as flat foot problems, among other issues. We also provide treatment for diabetic foot people, he continued.The centre currently performs about five surgeries per day and takes care for all different injuries, including sport injuries.According to the official, the centre also makes use of PRP (Platelet Rich Plasma) machine by which blood is taken from people and then separated. 'Using the PRP machine, we can inject the blood particles to the joints. This facility is available in HGH and the Bone and Joint Center, part of HMC, he noted.'Our clinics are at the Bone and Joint Center. All our patients come through the Bone and Joint Center. We are also in the process of introducing the weight-bearing CT scan machine. With this, we can scan the foot and ankle of the patient while he or she is standing on it. This can give better impression of the condition of the patients, he highlighted.'Some deformity can be better measured through this CT scan machine. It will also be used for treating the knee joint as it is one of the most advanced treatment options available now, he added.

If youre troubled by ache within the nerves, comply with the following tips, know – Sahiwal Tv
By daniellenierenberg
Many folks all over the world will be seen troubled by ache within the veins. And many occasions, even after an excessive amount of therapy, this ache shouldnt be relieved. But within the coming days youll be able to do away with neuralgia utterly, that too with none unwanted side effects. Researchers on the University of Sydney have used human stem cells for excessive ache reduction in mice. Now, theyre shifting in the direction of human trials.
Greg Nelly, senior researcher on the Charles Perkins Center, stated that at occasions, extreme stress on the nerves causes them to get broken. For instance, carpal tunnel syndrome is the median nerve within the fingers ( median nerve ) Due to extreme stress.
->As youll be able to think about, nerve accidents can result in insufferable neuropathic ache. There can also be no efficient therapy to alleviate ache in most sufferers.
Therefore, Nelly and colleagues on the University of Sydney developed an efficient remedy. Researchers have been in a position to create pain-relieving neurons utilizing human stem cells.
Nelly stated that this success implies that for some sufferers affected by nerve ache, we are able to carry out pain-relieving implants from our cells, which might cease the ache.
In the research, researchers collected stem cells from grownup blood samples. Then, used human-induced pluripotent stem cells (iPSCs) from the bone marrow to create pain-relieving cells within the laboratory.
To check the efficacy of the therapy, the group injected neurons that abolished spinal ache in mice affected by extreme neuropathic ache. It was revealed that this therapy supplied full reduction from ache to the mice with none unwanted side effects.
Co-senior creator Dr. Leslie Caron stated that because of this transplant remedy is prone to be an efficient and long-lasting therapy for neuropathic ache.
After shut therapy in mice, the University of Sydney group is shifting ahead for extra intensive research in pigs. Within the following 5 years, theyll check people who are suffering from power ache.
Researchers stated {that a} move check in people will probably be a giant success. This could point out the event of latest non-opioid, non-addictive ache administration methods for sufferers.

Scientists Think They Know How Stress Causes Gray Hair – Healthline
By daniellenierenberg
Sorry Mom and Dad: It turns out you might not have been exaggerating when you told us your children made your hair turn gray.
Stress may play a key role in just how quickly hair goes from colored to ashen, a study published this past week in the journal Nature suggests.
Scientists have long understood some link is possible between stress and gray hair, but this new research from Harvard University in Massachusetts more deeply probes the exact mechanisms at play.
The researchers initial tests looked closely at cortisol, the stress hormone that surges in the body when a person experiences a fight or flight response.
Its an important bodily function, but the long-term presence of heightened cortisol is linked to a host of negative health outcomes.
But the culprit ended up being a different part of the bodys fight or flight response the sympathetic nervous system.
These nerves are all over the body, including making inroads to each hair follicle, the researchers reported.
Chemicals released during the stress response specifically norepinephrine causes pigment producing stem cells to activate prematurely, depleting the hairs reserves of color.
The detrimental impact of stress that we discovered was beyond what I imagined, Ya-Chieh Hsu, PhD, a lead study author and an associate professor of stem cell and regenerative biology at Harvard, said in a press release. After just a few days, all of the pigment-regenerating stem cells were lost. Once theyre gone, you cant regenerate pigments anymore. The damage is permanent.
But stress isnt the only or even the primary reason that most people get gray hair.
In most cases, its simple genetics.
Gray hair is caused by loss of melanocytes (pigment cells) in the hair follicle. This happens as we age and, unfortunately, there is no treatment that can restore these cells and the pigment they produce, melanin, Dr. Lindsey A. Bordone, a dermatologist at ColumbiaDoctors and an assistant professor of dermatology at Columbia University Medical Center in New York, told Healthline. Genetic factors determine when you go gray. There is nothing that can be done medically to prevent this from happening when it is genetically predetermined to happen.
That doesnt mean environmental factors such as stress dont play a role.
Smoking, for instance, is a known risk factor for premature graying, according to a 2013 study. So kick the habit if you want to keep that color a little longer.
Other contributing factors to premature graying include deficiencies in protein, vitamin B-12, copper, and iron as well as aging due in part to an accumulation of oxidative stress.
That stress is prompted by an imbalance between free radicals and antioxidants in your body that can damage tissue, proteins, and DNA, Kasey Nichols, NMD, an Arizona physician and a health expert at Rave Reviews, told Healthline.
And some degree of oxidative stress is a natural part of life.
We would expect increasing gray hair as we advance in age, and we see about a 10 percent increase in the chance of developing gray hair for every decade after age 30, Nichols said.
Changes you can pursue to delay premature grays include eating a diet high in omega-3 fatty acids such as walnuts and fatty fish, not spending too much time in the skin-damaging and hair-damaging ultraviolet light of the sun, and taking vitamin B-12 and vitamin B-6 supplements.
That said, if you are going gray prematurely, it wouldnt hurt to go have a checkup just in case natural genetic factors arent the sole culprit.
The new Harvard research is only a mouse study, so replicating the same results in a human study would be necessary to strengthen the findings.
But the Harvard research has implications far beyond graying hair, with the hair color change merely one obvious sign of other internal changes as a result of prolonged stress.
By understanding precisely how stress affects stem cells that regenerate pigment, weve laid the groundwork for understanding how stress affects other tissues and organs in the body, said Hsu. Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress.
Might that also mean someday halting and reverting the march of premature gray hair? Its too soon to tell.
We still have a lot to learn in this area, Hsu said.

Roll play: Jade rollers and gua sha stone are making waves in skincare – Times of India
By daniellenierenberg
If you havent chanced upon a gua sha stone facial or a jade roller video on your social media, are you even on it? The ancient Chinese technique of face massaging is gaining traction thanks to beauty bloggers sharing their basic kneads. If you have stumbled upon these videos but have no clue whats going on, read on. Dermatologist Dr Nirupama Parwanda says that the basics come from traditional Chinese wisdom: improper blood circulation and stagnant blood flow is one of the main reasons behind various diseases. To improve circulation and drain toxins, you can try jade rollers and gua sha an alternative therapy that involves massaging your skin using special tools. Parwanda says, Our bodies have a source of energy known as chi flowing through it. And to ensure good health and prosperity, we must balance it. Dr Rinky Kapoor, dermatologist and dermato-surgeon, explains, Both rollers and gua sha are made of stones such as quartz, jade, rose quartz and amethyst known for their healing properties. Gua sha is also known as coining, skin scrapping or pressure stroking. FLOW AND GLOWBoth work on the principle of improving blood flow under the skin and enhancing lymphatic drainage. This helps carry the oxygen to the skin cells, which in turn makes the skin tissues healthy, and reduces fine lines and wrinkles. Parwanda says that gua sha is also called natural botox as it helps in controlling signs of ageing. The proven benefits are: pain reduction in muscles and joints; reduction in perimenopause symptoms like anxiety, insomnia, hot flashes; improved blood circulation, removal of toxins. It also treats musculoskeletal disorders and reduces wrinkles.
TOO GOOD TO BE TRUE?Kapoor cautions that just looking at videos online doesnt mean you know the proper way to use it. You need to follow the process to reap the maximum benefits. Also, theres not one simple process for both jade roller and gua sha. Think of it as driving while the basics of accelerator, brake and clutch remain the same, driving styles are different, she says. Start both facials from the neck and then move upwards and with upward strokes. Rollers are simpler to use as you can just start massaging on the outward and upward direction from one point, except for the neck, where the massaging motion is downwards. Gua sha facials require more technique. Tip: you can learn from a practitioner.

Alopecia: What causes the hair loss condition? – foxwilmington.com
By daniellenierenberg
Everyone sheds about 100 hairs each day as part of the normal hair growth cycle, but excess loss is usually a distressing development.(iStock)
Hair loss is typically considered the domain of aging men, but this equal-opportunity condition which has many causes can affect virtually anyone.
Alopecia is the medical term for hair loss, and it doesnt only happen on the scalp. Some illnesses and medications can trigger balding over the entire body, though genetics account for most cases on the head, according to theCleveland Clinic.
PARTY DRUG MDMA A STEP CLOSER TO LEGALIZATION FOR PTSD THERAPY
Everyone sheds about 100 hairs each day as part of the normal hair growth cycle, but excess loss is usually a distressing development. Americans spend more than $3.5 billion each year trying to treat it, according to theAmerican Hair Loss Association.
Most peoples hair grows about a half-inch per month, and about 90 percentof your hair is actively growing at any given time, with the other 10 percentin dormant phase. After two or three months, this dormant hair falls out and its follicles begin growing new hair as other follicles begin a dormant phase.
Shedding hair is different from hair loss, when a hair falls out and doesnt grow back. People often shed hair during stressful events, such aschildbirth, a breakup or divorce or during times of grief.
It still doesnt feel good, and it takes the hair [awhile] to reach a certain length where you perceive its presence, said Doris Day, a board-certified dermatologist New York City and an attending physician at Lenox Hill Hospital, also in New York. So it feels like a hair loss, but its not a hair loss.
Aside from heredity, noticeable hair loss can be caused by wide variety of factors, including:
Harsh hairstyles or treatments: Hairstyles that consistently use rubber bands, rollers or barrettes, or pull hair into tight styles such as cornrows, can inflame and scar hair follicles. So can incorrectly used chemical products such as dyes, bleaches, straighteners or permanent wave solutions. Depending on the degree of damage, resulting hair loss can be permanent.
Hormone imbalances: In women, hormonal shifts from birth control pills,pregnancy, childbirth, menopause or hysterectomy can induce more hair follicles than normal to enter the dormant phase.
Illness or surgery: The stress from sickness or surgery may prompt the body to temporarily cease nonessential tasks such as hair production. Specific conditions can also trigger it, including thyroid disorders,syphilis, iron deficiency,lupusor severe infection. An autoimmune condition called alopecia areata, which has no cure, causes rapid body-wide hair loss.
Medications and vitamins: Cancer chemotherapy, which attacks hair follicles in its attempt to kill all fast-growing cells around the body, is a well-known reason for hair loss. Other medications side effects include hair shedding as well, such as some that treat high blood pressure andgout(a painful joint condition caused by a buildup of uric acid). Excessive levels of vitamin A also contribute.
Nutritional deficits: Heavy dieting or eating disorders such asbulimiaandanorexiacan temporarily stun hair follicles to cease growth. This can also occur from insufficient protein, vitamin or mineral intake.
Aging: A natural effect of growing older is slowed hair growth.
Women usually dont go completely bald, but lose hair on the top of the head or the temples. Men tend to lose hair on their temples, and are more likely than women to go completely bald, Day said.
Dermatologists will examine the persons scalp and take a history of medical or stressful events to see whats been going on in their life and their world, Day said.
HELICOPTER-SHARING APP BLADE PAIRS WITH NYU LANGONE TO SPEED TRANSPLANT ORGANS
The dermatologist may take a biopsy a small patch of skin that includes the hair follicle and send it to a pathologist to determine if an autoimmune disease, such as lupus, is the cause of the hair loss.
Examining the hair and follicle can also determine whether someone has a bacterial or fungal infection, Day said.
Hair loss remedies range from the mild to the extreme and the inexpensive to the costly. Much depends on how much hair is gone and how high a priority it is to mask its absence or replace it.
According to the Cleveland Clinic, treatments include:
Hair weaves or wigs: Typically expensive, wigs and hair weaves either completely cover the head or add to existing hair, restoring the appearance of a full head of hair. They are especially practical for cancer patients and those whose hair loss is temporary.
Topical creams and lotions: Over-the-counter minoxidil (also known as the brand name Rogaine) can restore some hair growth, especially in those with hereditary hair loss. It is applied directly to the scalp. Prescription-strength finasteride (Propecia) comes in pill form and is only for men. According to theAmerican Academy of Family Physicians(AFP), it may take up to six months to tell if these medications are working.
Anti-inflammatory medications: Prescription steroid-based creams or injections can calm follicles damaged or inflamed by harsh chemicals or excessive pulling.
Surgery: Men tend to be better candidates for surgical hair-replacement techniques because their hair loss is often limited to one or two areas of the scalp. Procedures include grafting, which transplants from one to 15 hairs per disc-shaped graft to other locations. Scalp reduction removes bald skin from the scalp so hair-covered scalp can be stretched to fill in the bald areas. Side effects include swelling, bruising and headaches.
Hair-growth laser treatment can also help stimulate hair follicles and improve growth, Day said. People often see results when they combine laser treatment with another intervention, she said. Treatments range in price from $30 and up for Rogaine to about $3,000 for laser treatment, she added.
According to theNational Institute of Arthritis and Musculoskeletal and Skin Diseases(NIAMSD), alternative therapies may not help hair regrow and many are not supported by medical research. However, other treatments that reportedly improve alopecia areata include Chinese herbs, acupuncture, zinc and vitamin supplements, evening primrose oil and aroma therapy.
Viviscal, a natural supplement, has also shownmore hair growthin men compared to those who took fish extract in clinical trials, Day said.
The NIAMSD recommends discussing any alternative treatments with physicians before use.
The drug Tofacitinib is approved to treat adults witharthritis, but a growing number of cases suggest that it can also treat alopecia universalis, a condition in which people lose all of the hair on their body because theirimmune systemattacks hair follicles,Live Science previously reported.
The finding occurred after doctors prescribed a 25-year-old man with alopecia universalis the drug because they had heard it had treated a similar condition in mice,according to a statement from Yale University. After three months of treatment, the man had completely regrown the hair on his scalp, and he had visible eyebrows, eyelashes, facial hair, as well as hair elsewhere on his body.
Its exciting, said Day, who did not treat this particular patient. There seems to be a real effect here.

Its unclear how Tofacitinib (brand name Xeljanz) works, but researchers hope to determine its mechanism soon. This data may help them learn which biological pathways lead to hair loss.
There are now clinical trials taking place around the country to test the safety and efficacy of the drug for hair loss conditions. One such study lasting 3 months gave Tofacitinib to 66 people with alopecia areata (an immune system condition that causes hair to fall out in patches). Half of the people regrew some hair, and one-third had more than 50 percentof the hair on their scalp grow back, according to the 2016 study, published in the journalJCI Insight.
However, researchers are still working to determine the best dose needed, whether the results are lasting, and whether they can develop a topical form of the drug, Day said. She added that patients should be aware that Tofacitinib has side effects. Its already associated with an increased risk of serious infections, as well as stomach and intestinal tears, according to Pfizer, the manufacturer.
Besides investigating Tofacitinib, researchers are also looking at ways to clone hair or use stem cell therapy to treat alopecia, Day said.

Scientists prove link between stress and prematurely greying hair – Newstalk ZB
By daniellenierenberg
Marie Antoinette's hair suddenly turned white before the ill-fated French queen was taken to the guillotine to have her head chopped off, according to some historical accounts.
More modern reports refer to hair turning prematurely white in survivors of bomb attacks during World War II, while an Australian airline pilot saw his hair go grey in the months after landing a plane following a failure of all four engines in the early 1980s.
While there's been plenty of anecdotal evidence suggesting premature greying can be caused by extreme stress -- whether this is true and how this happens isn't widely understood.
Now, Harvard University scientists think they have the answer -- at least in mice.
The group of researchers believe it's down to the animal's sympathetic nervous system -- which is best known for activating our "fight or flight" response to danger, they say.
"Under stress, our sympathetic nerve becomes highly activated," said Ya-Chieh Hsu, associate professor of stem cell and regenerative biology at Harvard, in an email. "And actually, activation of the sympathetic nervous system under stress is supposed to be a good thing."
Its activation triggers the "fight or flight" response through the neurotransmitter norepinephrine, or noradrenaline, explained Hsu, a senior author of the study published Wednesday in the scientific journal Nature. "Noradrenaline raises our heartbeat and allows us to react quickly to danger without having to think about it," he said.
"However, it is the same noradrenaline that turns out to be bad for melanocyte stem cells at a high level, and triggers their loss."
Melanocyte stem cells are found in hair follicles and determine hair colour. In people, the pool of these cells deplete as they age, turning hair grey as pigment depletes. Their loss from excessive noradrenaline could be causing this to happen prematurely, the team suggest.
Loss of pigment
The team had thought that acute stress might trigger an immune attack on pigment-producing stem cells or that the blame lied with the hormone cortisol because cortisol levels are elevated under stress. Hsu said they went through many different possibilities before focusing on the sympathetic nervous system.
"We were really surprised to find that it was the culprit, because it is normally seen as a beneficial system, or at least transient and reversible," she said.
The team put mice under three different types of stress through what Hsu described as established standard protocols. These included a single injection of a chemical to activate the mouse's pain fiber, cage tilting and rapid changes between light and dark.
Changes were observed in all mice but there was some variability, with white hair only coming out after all the stem cells are gone.
"Some hair follicles have reduced levels of melanocyte stem cells so they can still make pigment, while others have lost all stem cells and can't make pigment anymore, so the hair becomes white," she said.
Pigment-producing stem cells and the sympathetic nervous system are very similar in mice and humans, explained Hsu who was hopeful that the mechanisms would be related. But future studies would be needed to provide definitive evidence, she said.
"Everyone has an anecdote to share about how stress affects their body, particularly in their skin and hair the only tissues we can see from the outside," Hsu said in a news release.
"We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with and besides, we were genuinely curious to see if stress indeed leads to hair greying."
Hsu said the findings may also help shed light on the effects of stress on various organs and tissues, and pave the way for new studies that seek to modify or block the damaging effects of stress.
In an accompanying article, Shayla Clark and Christopher Deppmann, researchers from the Neuroscience Graduate Program at the University of Virginia, who were not involved in the study, said it was interesting to consider what possible evolutionary advantage might be conferred by stress-induced greying.
"Because grey hair is most often linked to age, it could be associated with experience, leadership and trust. Perhaps an animal that has endured enough stress to 'earn' grey hair has a higher place in the social order than would ordinarily be conferred by that individual's age," they wrote.

How I Went From Managing Complexity to Becoming a U.S. Ambassador and CEO – SWAAY
By daniellenierenberg
With so many groundbreaking medical advances being revealed to the world every single day, you would imagine there would be some advancement on the plethora of many female-prevalent diseases (think female cancers, Alzheimer's, depression, heart conditions etc.) that women are fighting every single day.
For Anna Villarreal and her team, there frankly wasn't enough being done. In turn, she developed a method that diagnoses these diseases earlier than traditional methods, using a pretty untraditional method in itself: through your menstrual blood.
Getting from point A to point B wasn't so easy though. Villarreal was battling a disease herself and through that experience. I wondered if there was a way to test menstrual blood for female specific diseases," she says. "Perhaps my situation could have been prevented or at least better managed. This led me to begin researching menstrual blood as a diagnostic source. For reasons the scientific and medical community do not fully understand, certain diseases impact women differently than men. The research shows that clinical trials have a disproportionate focus on male research subjects despite clear evidence that many diseases impact more women than men."
There's also no denying that gap in women's healthcare in clinical research involving female subjects - which is exactly what inspired Villarreal to launch her company, LifeStory Health. She says that, with my personal experience everything was brought full circle."
There is a challenge and a need in the medical community for more sex-specific research. I believe the omission of females as research subjects is putting women's health at risk and we need to fuel a conversation that will improve women's healthcare.,"
-Anna Villarreal
Her brand new biotech company is committed to changing the women's healthcare market through technology, innovation and vocalization and through extensive research and testing. She is working to develop the first ever, non-invasive, menstrual blood diagnostic and has partnered with a top Boston-area University on research and has won awards from The International Society for Pharmaceutical Engineering and Northeastern University's RISE.
How does it work exactly? Proteins are discovered in menstrual blood that can quickly and easily detect, manage and track diseases in women, resulting in diseases that can be earlier detected, treated and even prevented in the first place. The menstrual blood is easy to collect and since it's a relatively unexplored diagnostic it's honestly a really revolutionary concept, too.
So far, the reactions of this innovative research has been nothing but excitement. The reactions have been incredibly positive." she shares with SWAAY. Currently, menstrual blood is discarded as bio waste, but it could carry the potential for new breakthroughs in diagnosis. When I educate women on the lack of female subjects used in research and clinical trials, they are surprised and very excited at the prospect that LifeStory Health may provide a solution and the key to early detection."
To give a doctor's input, and a little bit more of an explanation as to why this really works, Dr. Pat Salber, MD, and Founder of The Doctor Weighs In comments: researchers have been studying stem cells derived from menstrual blood for more than a decade. Stem cells are cells that have the capability of differentiating into different types of tissues. There are two major types of stem cells, embryonic and adult. Adult stem cells have a more limited differentiation potential, but avoid the ethical issues that have surrounded research with embryonic stem cells. Stem cells from menstrual blood are adult stem cells."
These stem cells are so important when it comes to new findings. Stem cells serve as the backbone of research in the field of regenerative medicine the focus which is to grow tissues, such as skin, to repair burn and other types of serious skin wounds.
A certain type of stem cell, known as mesenchymal stem cells (MenSCs) derived from menstrual blood has been found to both grow well in the lab and have the capability to differentiate in various cell types, including skin. In addition to being used to grow tissues, their properties can be studied that will elucidate many different aspects of cell function," Dr. Salber explains.
To show the outpour of support for her efforts and this major girl power research, Villarreal remarks, women are volunteering their samples happily report the arrival of their periods by giving samples to our lab announcing de-identified sample number XXX arrived today!" It's a far cry from the stereotype of when it's that time of the month."
How are these collections being done? Although it might sound odd to collect menstrual blood, plastic cups have been developed to use in the collection process. This is similar to menstrual products, called menstrual cups, that have been on the market for many years," Dr. Salber says.
Equally shocking and innovative, this might be something that becomes more common practice in the future. And according to Dr. Salber, women may be able to not only use the menstrual blood for early detection, but be able to store the stem cells from it to help treat future diseases. Companies are working to commercialize the use of menstrual blood stem cells. One company, for example, is offering a patented service to store menstrual blood stem cells for use in tissue generation if the need arises."

Weekly pick of brain tumour research news from around the world – Brain Tumour Research
By daniellenierenberg
The first symposium of the South West Brain Tumour Centre was held on Thursday at Derriford Hospital in Plymouth. During a fascinating and very well attended event, topics covered included the mechanism of tumour development, new drug targets, new biomarkers and brain tumour imaging. The South West Brain Tumour centre is of course one of the UK Centres of Excellence funded by Brain Tumour Research.
A really big cancer wide story this week is here Immune discovery 'may treat all cancer' applicable to some solid tumours but not yet brain it really shows the direction of travel toward immunotherapy I have recommended this book before but if interested please do read The Breakthrough by Charles Graeber it is available on Amazon and you can read reviews here - http://www.charlesgraeber.com.Researchers uncover novel drug target for glioblastoma by revealing a cellular pathway that appears to contribute to glioma stem cell spread and proliferation. This pathway shows that glioma stem cells ability to access key nutrients in their surrounding microenvironment is integral for their maintenance and spread. Finding a way to interrupt this feedback loop will be important for treating glioblastoma.
An intelligent molecule could significantly extend the lives of patients with glioblastoma, research finds. The molecule, called ZR2002, which can be administered orally and is capable of penetrating the blood-brain barrier, could delay the multiplication of glioblastoma stem cells resistant to standard treatment. According to scientists in the Metabolic Disorders and Complications Program at the Research Institute of the McGill University Health Centre (RI-MUHC) the ZR2002 molecule is designed to kill two birds with one stone: on top of attacking the tumour, it destroys its defence system.
Researchers find clues to drug resistance in medulloblastoma subtype.US scientists have identified specific types of cells that cause targeted treatment to fail in a subtype of medulloblastoma. They found while the majority of cells responded to treatment, diverse populations within the tumour continue to grow leadingto treatment resistance. They concluded that the diversity of cells within tumours allow them to become rapidly resistant to precisely targeted treatments," and that due to this tumour cell diversity, molecularly precise therapies should be used in combinations to be effective."
Nanoparticles deliver 'suicide gene' therapy to paediatric brain tumours growing in mice So-called "suicide genes" have been studied and used in cancer treatments for more than 25 years. Researchers report here that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a ''suicide gene'' to paediatric brain tumour cells implanted in the brains of mice.
According to a study that uncovers an unexpected connection between gliomas and neurodegenerative diseases a protein typically associated with neurodegenerative diseases like Alzheimers might help scientists explore how gliomas become so aggressive. The new study, in mouse models and human brain tumour tissues, was published in Science Translational Medicine and found a significant expression of the protein TAU in glioma cells, especially in those patients with better prognoses. Patients with glioma are given a better prognosis when their tumour expresses a mutation in a gene called isocitrate dehydrogenase 1 (IDH1). In this international collaborative study led by the Instituto de Salud Carlos III-UFIEC in Madrid, Spain, those IDHI mutations stimulated the expression of TAU. Then, the presence of TAU acted as a brake for the formation of new blood vessels, which are necessary for the aggressive behaviour of the tumours.
'Innovative research award' helps Colorado scientists block brain cancer escape routes Cancers used to be defined by where they grow in the body - lung cancer, skin cancer, brain cancer, etc. But work in recent decades has shown that cancers sharing specific genetic changes may have more in common than cancers that happen to grow in an area of the body. For example, lung cancers, skin cancers, and brain cancers may all be caused by mutation in a gene called BRAF. Drugs targeting BRAF have changed the treatment landscape for melanoma, an aggressive form of skin cancer, and are also in use against lung cancers and brain cancers with BRAF mutations. It is really worth clicking through to read more on this and the ultimate goal of identifying new potential targets for combination therapy and new agents that could be added to BRAF inhibiting drugs in brain cancer to keep the cancer from developing resistance.

When I educate women on the lack of female subjects used in research and clinical trials, they are surprised and very excited at the prospect that LifeStory Health may provide a solution and the key to early detection."
To give a doctor's input, and a little bit more of an explanation as to why this really works, Dr. Pat Salber, MD, and Founder of The Doctor Weighs In comments: researchers have been studying stem cells derived from menstrual blood for more than a decade. Stem cells are cells that have the capability of differentiating into different types of tissues. There are two major types of stem cells, embryonic and adult. Adult stem cells have a more limited differentiation potential, but avoid the ethical issues that have surrounded research with embryonic stem cells. Stem cells from menstrual blood are adult stem cells."
These stem cells are so important when it comes to new findings. Stem cells serve as the backbone of research in the field of regenerative medicine the focus which is to grow tissues, such as skin, to repair burn and other types of serious skin wounds.
A certain type of stem cell, known as mesenchymal stem cells (MenSCs) derived from menstrual blood has been found to both grow well in the lab and have the capability to differentiate in various cell types, including skin. In addition to being used to grow tissues, their properties can be studied that will elucidate many different aspects of cell function," Dr. Salber explains.
To show the outpour of support for her efforts and this major girl power research, Villarreal remarks, women are volunteering their samples happily report the arrival of their periods by giving samples to our lab announcing de-identified sample number XXX arrived today!" It's a far cry from the stereotype of when it's that time of the month."
How are these collections being done? Although it might sound odd to collect menstrual blood, plastic cups have been developed to use in the collection process. This is similar to menstrual products, called menstrual cups, that have been on the market for many years," Dr. Salber says.
Equally shocking and innovative, this might be something that becomes more common practice in the future. And according to Dr. Salber, women may be able to not only use the menstrual blood for early detection, but be able to store the stem cells from it to help treat future diseases. Companies are working to commercialize the use of menstrual blood stem cells. One company, for example, is offering a patented service to store menstrual blood stem cells for use in tissue generation if the need arises."

Scientists zero in on exact reason behind the link between stress and graying of hair – International Business Times, Singapore Edition
By daniellenierenberg
It is not uncommon to hear people say that stress causes one's hair to gray. Many famous American Presidents such as George W. Bush and Barrack Obama grayed drastically by the end of their taxing presidencies. Yet, the real exact behind the process has eluded scientists... Until now.
Researchers from Harvard University have finally uncovered the precise mechanism that causes graying using mice. Stress triggers nerves that are closely involved in the fight-or-flight response. This, in turn, causes irreversible damage to pigment-regenerating stem cells that are found in the hair follicles.
"We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with and besides, we were genuinely curious to see if stress indeed leads to hair graying," said Chieh Hsu, senior author of the study, in a statement.
Stress affects the entire body. Therefore, the researchers had to first ascertain which system of the body was responsible for linking hair colour to stress. The first hypothesises that was formulated was that stress leads to an immune attack against pigment-producing cells. However, the scientists found that in spite of lacking immune cells, some mice continued to exhibit graying of hair. This prompted the researchers to assess the hormone cortisolwhich also did not prove to be the real culprit.
Citing the increase in the levels of cortisol as a response to stress, the team assumed that hormone played a role in the graying processonly to learn that it did not. "But surprisingly, when we removed the adrenal gland from the mice so that they couldn't produce cortisol-like hormones, their hair still turned gray under stress," Hsu said.
Following the striking down of immune response and cortisol levels from a list of possible causes, the researchers began systematically eliminating the various possibilities. Finally, they set their sights on the sympathetic nerve system, which is attributed to controlling the body's fight-or-flight response.
Sympathetic nerves branch into every hair follicle on the skin. What the authors discovered was that stress promotes the release of the chemical norepinephrine by these nerves. The released chemical is absorbed by the pigment-regenerating stem cells that are situated nearby.
Specific stem cells within the hair follicle act as a reservoir of pigment-generating cells. During the regeneration of hair, some of the stem cells are converted into pigment-producing cells that give hair its color.
The team found that the norepinephrine produced by the sympathetic nerves causes uncontrolled activation of the stem cells. All the stem cells now turn into pigment-producing cells, which in turn lead to the premature depletion of the reservoir.
"Acute stress, particularly the fight-or-flight response, has been traditionally viewed to be beneficial for an animal's survival. But in this case, acute stress causes permanent depletion of stem cells," said Bing Zhang, lead author of the study. Therefore, the study highlights the damaging side effects of a generally beneficial evolutionary response that is often considered vital for survival.
In order to make the connection between stress and graying, the researchers began with a complete-body response and gradually focussed on individual organ systems, cell-to-cell interactions, and finally, down to molecular dynamics. A range of research tools was employed for this process, including techniques to manipulate cell receptors, nerves and organs.
For the intrinsic study that focussed on various macro and micromechanisms of the body, the researchers collaborated with scientists across various disciplines. One such collaborator was Isaac Chiu, assistant professor of immunology at Harvard Medical School.
Pointing out that the current study learned beyond the various known capacities of neurons, Chiu said, "With this study, we now know that neurons can control stem cells and their function, and can explain how they interact at the cellular and molecular level to link stress with hair graying."
The researchers say that these findings may further the understanding of broad-ranging effects of stress on various types of tissues and organs. This knowledge will provide a new foundation to study and develop ways to block or modify the effects of stress.
"Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress. We still have a lot to learn in this area," concluded Hsu.

When Marie Antoinette was captured during the French Revolution, her hair reportedly turned white overnight. In more recent history, John McCain experienced severe injuries as a prisoner of war during the Vietnam War and lost color in his hair.
For a long time, anecdotes have connected stressful experiences with the phenomenon of hair graying. Now, for the first time, Harvard University scientists have discovered exactly how the process plays out: stress activates nerves that are part of the fight-or-flight response, which in turn cause permanent damage to pigment-regenerating stem cells in hair follicles.
The study, published in Nature, advances scientists knowledge of how stress can impact the body.
Everyone has an anecdote to share about how stress affects their body, particularly in their skin and hair the only tissues we can see from the outside, said senior author Ya-Chieh Hsu, the Alvin and Esta Star Associate Professor of Stem Cell and Regenerative Biology at Harvard. We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with and besides, we were genuinely curious to see if stress indeed leads to hair graying.
Narrowing down the culprit
Because stress affects the whole body, researchers first had to narrow down which body system was responsible for connecting stress to hair color. The team first hypothesized that stress causes an immune attack on pigment-producing cells. However, when mice lacking immune cells still showed hair graying, researchers turned to the hormone cortisol. But once more, it was a dead end.
Stress always elevates levels of the hormone cortisol in the body, so we thought that cortisol might play a role, Hsu said. But surprisingly, when we removed the adrenal gland from the mice so that they couldnt produce cortisol-like hormones, their hair still turned gray under stress.
After systematically eliminating different possibilities, researchers honed in on the sympathetic nerve system, which is responsible for the bodys fight-or-flight response.
Sympathetic nerves branch out into each hair follicle on the skin. The researchers found that stress causes these nerves to release the chemical norepinephrine, which gets taken up by nearby pigment-regenerating stem cells.
Permanent damage
In the hair follicle, certain stem cells act as a reservoir of pigment-producing cells. When hair regenerates, some of the stem cells convert into pigment-producing cells that color the hair.
Researchers found that the norepinephrine from sympathetic nerves causes the stem cells to activate excessively. The stem cells all convert into pigment-producing cells, prematurely depleting the reservoir.
When we started to study this, I expected that stress was bad for the body but the detrimental impact of stress that we discovered was beyond what I imagined, Hsu said. After just a few days, all of the pigment-regenerating stem cells were lost. Once theyre gone, you cant regenerate pigment anymore. The damage is permanent.
The finding underscores the negative side effects of an otherwise protective evolutionary response, the researchers said.
Acute stress, particularly the fight-or-flight response, has been traditionally viewed to be beneficial for an animals survival. But in this case, acute stress causes permanent depletion of stem cells, said postdoctoral fellow Bing Zhang, the lead author of the study.
Answering a fundamental question
To connect stress with hair graying, the researchers started with a whole-body response and progressively zoomed into individual organ systems, cell-to-cell interaction and, eventually, all the way down to molecular dynamics. The process required a variety of research tools along the way, including methods to manipulate organs, nerves, and cell receptors.
To go from the highest level to the smallest detail, we collaborated with many scientists across a wide range of disciplines, using a combination of different approaches to solve a very fundamental biological question, Zhang said.
The collaborators included Isaac Chiu, assistant professor of immunology at Harvard Medical School who studies the interplay between nervous and immune systems.
We know that peripheral neurons powerfully regulate organ function, blood vessels, and immunity, but less is known about how they regulate stem cells, Chiu said.
With this study, we now know that neurons can control stem cells and their function, and can explain how they interact at the cellular and molecular level to link stress with hair graying.
The findings can help illuminate the broader effects of stress on various organs and tissues. This understanding will pave the way for new studies that seek to modify or block the damaging effects of stress.
By understanding precisely how stress affects stem cells that regenerate pigment, weve laid the groundwork for understanding how stress affects other tissues and organs in the body, Hsu said. Understanding how our tissues change under stress is the first critical step towards eventual treatment that can halt or revert the detrimental impact of stress. We still have a lot to learn in this area.
The study was supported by the Smith Family Foundation Odyssey Award, the Pew Charitable Trusts, Harvard Stem Cell Institute, Harvard/MIT Basic Neuroscience Grants Program, Harvard FAS and HMS Deans Award, American Cancer Society, NIH, the Charles A. King Trust Postdoctoral Fellowship Program, and an HSCI junior faculty grant.

Kyoto University team gets OK from ministry for plan to transplant iPS-derived cartilage into knee joints – The Japan Times
By daniellenierenberg
KYOTO An expert panel of the health ministry on Friday approved a clinical research program proposed by a Kyoto University team to transplant cartilage made from induced pluripotent stem (iPS) cells to damaged knee joints.
Professor Noriyuki Tsumaki and other members of the team are planning to create cartilage with a diameter of 2 to 3 millimeters using iPS cells stored at the universitys Center for iPS Cell Research and Application (CiRA).
The team aims to carry out the first transplant this year. After a clinical trial by Asahi Kasei Corp., which supports the project, it hopes to put the technology into practical use in 2029.
Four people between the ages of 20 and 70 will undergo transplant operations using iPS cell-derived cartilage for their damaged knee joints, with the area of damage ranging from 1 centimeter to 5 centimeters. The team does not plan to seek additional patients for the program.
The team will monitor the four patients for one year after the operations to keep an eye out for possible development of tumors. If the operations succeed, the transplanted material will fuse with existing cartilage.
There are many patients experiencing inconvenience due to damaged cartilage, Tsumaki told a news conference at the Kyoto University Hospital on Friday. Well work hard so that we can offer therapy methods.
The team will also aim to apply the therapy to patients with osteoarthritis.
In 2014, Riken, a Japanese government-affiliated research institute, transplanted retina cells made from iPS cells as a treatment for an incurable eye disease, in the worlds first transplant of iPS-derived cells.
Later, similar transplant operations were conducted by Kyoto University for Parkinsons disease and by Osaka University for corneal disease.

KYOTO A panel of experts from the Ministry of Health approved a clinical research program proposed by a team from the University of Kyoto on Friday for the transplantation of cartilage from induced pluripotent stem cells [iPS] into damaged knee joints.
Professor Noriyuki Tsumaki and other members of the team are planning to produce 2 to 3 millimeter diameter cartilage using iPS cells, which will be stored at the Universitys Center for iPS Cell Research and Application [CiRA].
The team plans to perform the first transplant this year. According to a clinical study by Asahi Kasei Corp., which supports the project, the technology should be put into practice in 2029.

Immunosuppressors are not used in the transplant because cartilage usually does not show an immune response.
The team will monitor the four patients for possible tumor development for a year after the operation. If the operations are successful, the transplanted material melts into the existing cartilage.
There are many patients who experience discomfort from cartilage damage, said Tsumaki at a press conference at Kyoto University Hospital on Friday. We will work hard to offer therapy methods.
The team will also try to apply the therapy to patients with osteoarthritis.

El Paso scientists team up for heart research project at the International Space Station – KVIA El Paso
By daniellenierenberg
EL PASO, Texas -- Biomedical research scientists from Texas Tech University Health Sciences Center El Paso and The University of Texas at El Paso are partnering up to send "artificial mini-hearts" to the International Space Station to better understand how microgravity affects the function of the human heart.
The three-year project, funded by the National Science Foundation (NSF) and the space station's U.S. National Laboratory, brings together TTUHSC El Paso faculty scientist Munmun Chattopadhyay, Ph.D., and UTEP biomedical engineer Binata Joddar, Ph.D. The researchers will collaborate in their Earth-bound labs to create tiny (less than 1 millimeter thick) heart-tissue structures, known as cardiac organoids, using human stem cells and 3D bioprinting technology.
By exposing the organoids to the near-weightless environment of the orbiting space station, the researchers hope to gain a better understanding of a health condition known as cardiac atrophy, which is a reduction and weakening of heart tissue. Cardiac atrophy often affects astronauts who spend long periods of time in microgravity. A weakened heart muscle has difficulty pumping blood to the body, and can lead to problems such as fainting, irregular heartbeat, heart valve problems and even heart failure. Cardiac atrophy is also associated with chronic disease.
The first year of the project, which began in September, will focus on research design. During this phase, Dr. Joddar will use 3D printing to fabricate the cardiac organoids by coupling cardiac cells in physiological ratios to mimic heart tissue. The second year will be centered on preparing the organoid payload for a rocket launch and mission in space. The third and final year of the research will involve analyzing data from the experiment after the organoids are returned to Earth.
The project will also provide an educational opportunity for the El Paso community, with a workshop for K-12 students to learn about tissue engineering projects on the space station. It will also include a seminar for medical students, interns and residents about the benefits and challenges of transitioning research from Earth-based laboratories into space.

If you want to ban fetal tissue research, sign a pledge to refuse its benefits – USA TODAY
By daniellenierenberg
Irving Weissman and Joseph McCune, Opinion contributors Published 7:00 a.m. ET Jan. 24, 2020
Severe Trump administration restrictions mean millions of Americans of all political and religious stripes won't benefit from fetal tissue research.
Last summer the Trump administration curtailed federal funding of medical research using human fetal tissue; the new rulestook effect Oct. 1. More recently, the administration addedrestrictions that are even more severe.
Immediately, important work at two NIH-supported labs in Montana and California that are fighting the AIDS epidemic stopped because they were testing new medications against HIV using mice with human immune systems derived from human fetal tissue. In the near term, all National Institutes of Health (NIH) funding of research using fetal tissuewill likely cease.
More than 30years ago, we invented SCID-hu mice for biomedical research on diseases affecting humans, by implanting human fetal blood-forming and immune system tissuesinto mice whose immune systems had been silenced. The implanted immune tissues came from an aborted fetus, and allowed our otherwise immune-deficient mice to exist and be vulnerable to viruses that infect humans.
Tissues from living infants would not have worked;they are too far along in development and nearly impossible to obtain. This mouse model (and later versions of it) became the only living system, outside of a human, in which advanced therapies for diseases like AIDS and other viral infections could be evaluated before they were given to people.
Our work with human fetal tissue proceeded with the highest level of caution and vigilance. We received advice from bioethicists, clergyand government officials, which led to the establishment of strict guidelines that are still used today. No woman was asked or paid to terminate a pregnancy, the termination process was unaltered, and the women were asked for donation of the organs only after they had decided to terminate the pregnancy. Thus, obtaining the fetal tissue for medical research had no impact on ending pregnancies.
Since then, mice with transplanted human fetal tissues have been successfully used by scientists to identify blood stem cells and to devise treatments now availableor in clinical trialsfor cancer, various viral infections, Alzheimers disease, spinal cord injuries, and other diseases of the nervous system. Such diseases kill or cripple many Americans including pregnant women, fetusesand newborn infants. Many of them have only a short window of opportunity wherein a new therapy can treat them, and a delay can be fatal.

The Trump administration's new rules are tantamount to a funding ban. In academic labs, the experiments are done by students and fellows in training, and the new rules block any NIH-funded students or fellows from working with human fetal tissue. Those who imposed the banmust bear responsibility for the consequences: People will suffer and die for lack of adequate treatments.
Americans pay the price:Trump administration's 'scientific oppression' threatens US safety and innovation
At a December 2018 meeting at NIH,after hearing scientific evidence about alternative research methods such as the use of adult cells, experts concluded that the use of fetal tissue is uniquely valuable. Nonetheless, the administration severely restricted the use of fetal tissue, thereby denying millions of Americans the fruits of such research Americans of all political stripes, since deadly viruses and cancers do not care who you vote for.
These restrictions subvert the NIH mission, which is to advance medicine and protect the nations health. To the extent that it was motivated by the religious beliefs of those in charge, it bluntly transgresses the American principle of separation of church and state. As a result, both believers and non-believers will die.
Of course, all who take the Hippocratic Oathto "do no harm,"which includes all medical doctors, will always offer and deliver all types of therapies that are available.
Restricting science: Trump EPA's cynical 'transparency' ploy would set back pollution science and public health
However, we believe that thoseresponsible forthis de facto ban, and perhapsthose who agree with them, should personally accept its consequences. We challenge them tobe true to their beliefs. They should pledge to never accept any cancer therapy, any AIDS medication, any cardiac drug, any lung disease treatment, any Alzheimers therapy, or any other medical advance that was developed using fetal tissue including our mice. Its a long list, one that you can learn about from us here. Should this apply to you, be faithful and be bold: Take the pledge.

Watch | Stem cell banking and its benefits – The Hindu
By daniellenierenberg
The blood collected from the umbilical cord of the newborn is a rich source of stem cells. This blood is collected and sent to a cord blood bank, where the stem cells are separated, tested, processed, and preserved in liquid nitrogen. Technically, there is no expiry date and these stem cells can be preserved for a lifetime. Scientifically, evidence exists that they can be stored for about 20 years. The stem cells can treat around 70 blood related disorders and genetic disorders including thalassemia, sickle cell anaemia, leukaemia, and immune related disorders.
Stem cells taken from umbilical cord blood are like those taken from bone marrow, capable of producing all blood cells: red cells, platelets and immune system cells. When used, stem cells are first concentrated, then injected into the patient. Once transfused, they produce new cells of every kind.
They're capable of producing all types of blood cells: red cells, platelets and immune system cells. The stem cells can treat around 80 blood related illnesses like leukaemia, lymphomas, several genetic conditions and immune related disorders. But given the present state of medicine, they are effective only for around a dozen of them

Europe’s guardian of stem cells and hopes, real and unrealistic – Yahoo News
By daniellenierenberg
Poland has emerged as Europe's leader in stem cell storage, a billion-dollar global industry that is a key part of a therapy that can treat leukaemias but raises excessive hopes.
Submerged in liquid nitrogen vapour at a temperature of minus 175 degrees Celsius, hundreds of thousands of stem cells from all over Europe bide their time in large steel barrels on the outskirts of Warsaw.
Present in blood drawn from the umbilical cord of a newborn baby, stem cells can help cure serious blood-related illnesses like leukaemias and lymphomas, as well as genetic conditions and immune system deficits.
Polish umbilical cord blood bank PBKM/FamiCord became the industry's leader in Europe after Swiss firm Cryo-Save went bankrupt early last year.
It is also the fifth largest in the world, according to its management, after two companies in the United States, a Chinese firm and one based in Singapore.
Since the first cord blood transplant was performed in France in 1988, the sector has significantly progressed, fuelling hopes.
- Health insurance -
Mum-of-two Teresa Przeborowska has firsthand experience.
At five years old, her son Michal was diagnosed with lymphoblastic leukaemia and needed a bone marrow transplant, the entrepreneur from northern Poland said.
The most compatible donor was his younger sister, Magdalena.
When she was born, her parents had a bag of her cord blood stored at PBKM.
More than three years later, doctors injected his sister's stem cells into Michal's bloodstream.
It was not quite enough for Michal's needs but nicely supplemented harvested bone marrow.
As a result, Michal, who is nine, "is now flourishing, both intellectually and physically," his mum told AFP.
A cord blood transplant has become an alternative to a bone marrow transplant when there is no donor available, with a lower risk of complications.
Stem cells taken from umbilical cord blood are like those taken from bone marrow, capable of producing all blood cells: red cells, platelets and immune system cells.
Story continues
When used, stem cells are first concentrated, then injected into the patient. Once transfused, they produce new cells of every kind.
At the PBKM laboratory, "each container holds up to 10,000 blood bags... Safe and secure, they wait to be used in the future," its head, Krzysztof Machaj, said.
The bank holds around 440,000 samples, not including those from Cryo-Save, he said.
If the need arises, the "blood will be ready to use without the whole process of looking for a compatible donor and running blood tests," the biologist told AFP.
For families who have paid an initial nearly 600 euros ($675) and then an annual 120 euros to have the blood taken from their newborns' umbilical cords preserved for around 20 years, it is a kind of health insurance promising faster and more effective treatment if illness strikes.
But researchers also warn against unrealistic expectations.
- Beauty products -
Haematologist Wieslaw Jedrzejczak, a bone marrow pioneer in Poland, describes promoters of the treatment as "sellers of hope", who "make promises that are either impossible to realise in the near future or downright impossible to realise at all for biological reasons."
He compares them to makers of beauty products who "swear their cream will rejuvenate the client by 20 years."
Various research is being done on the possibility of using the stem cells to treat other diseases, notably nervous disorders. But the EuroStemCell scientist network warns that the research is not yet conclusive.
"There is a list of almost 80 diseases for which stem cells could prove beneficial," US haematologist Roger Mrowiec, who heads the clinical laboratory of the cord blood programme Vitalant in New Jersey, told AFP.
"But given the present state of medicine, they are effective only for around a dozen of them, like leukaemia or cerebral palsy," he said.
"It's not true, as it's written sometimes, that we can already use them to fight Parkinson's disease or Alzheimer's disease or diabetes."
EuroStemCell also cautions against private blood banks that "advertise services to parents suggesting they should pay to freeze their child's cord blood... in case it's needed later in life."
"Studies show it is highly unlikely that the cord blood will ever be used for their child," the network said.
It also pointed out that there could be a risk of the child's cells not being useable anyway without reintroducing the same illness.
Some countries, such as Belgium and France, are cautious and ban the storage of cord blood for private purposes. Most EU countries however permit it while imposing strict controls.
- Rapid growth -
In the early 2000s, Swiss company Cryo-Save enjoyed rapid growth.
Greeks, Hungarians, Italians, Spaniards and Swiss stored blood from their newborns with the company for 20 years on payment of 2,500 euros upfront.
When the firm was forced to close in early 2019, clients were left wondering where their stem cells would end up.
Under a kind of back-up agreement, the samples of some 250,000 European families were transferred for storage at PBKM.
The Polish firm, founded in 2002 with two million zlotys (around 450,000 euros, $525,000), has also grown quickly.
Present under the FamiCord brand in several countries, PBKM has some 35 percent of the European market, excluding Cryo-Save assets.
Over the last 15 months, outside investors have contributed 63 million euros to the firm, PBKM's chief executive Jakub Baran told AFP.
But the company has not escaped controversy: the Polityka weekly recently published a critical investigative report on several private clinics that offer what was described as expensive treatment involving stem cells held by PBKM.

UAB scientist studies aging through gray hair, says hair could be rejuvenated – AL.com
By daniellenierenberg
Gray hair got you down? Scientists may have a cure for that.
Okay, maybe not a cure. But, more information about why youre going gray, and what can be done about it.
Dr. Melissa Harris, an assistant professor at the University of Alabama at Birminghams Department of Biology, has spent the last ten years studying melanocyte stem cells and what happens when they fail.
Harris runs a molecular biology lab at UAB and uses CRISPR gene editing tools, single-cell sequencing studies, and network analysis algorithms. She uses gray hair as a model for aging, because she doesnt always need a microscopeshe can see the state of your melanocyte stem cells right away. If hair is all one color, Harris said, the melanocyte stem cells are healthy; but if there are grays mixed in, something isnt right.
Gray hair isnt always an inevitable part of aging, the university said. Through Harris research, shes learned that age isnt the only reason these cells fail, and now Harris is working with gray-haired mice to show there could be a way to bring the cells- and hair pigments- back to life. Shes doing that by working with a biotech startup to study an experimental compound that appears to restore hair color long-term in those mice.
Harris work applies to autoimmune diseases and to melanoma, but she said her primary goal is to understand why somatic stem cells (those found in muscles, bones, and organs that are responsible for tissue regeneration, immune defense, hair color and more) start to fail as a person ages. Most of those stem cell populations are hard to work with in the lab, Harris said, but melanocyte stem cells are an exception.
Does hair graying cause you to die? Harris said. No, you can watch melanocyte stem cells from birth to the end. But, she added that the same cant be said for cells like hematopoetic stem cells, which pump red blood cells in bone marrow. You cant live long without them, Harris said.
Her research will reveal more about the bodys aging process and the life cycles of those stem cells.
Harris is often known as the gray-hair lady in the lab, but she stresses that her gray hair research has bigger implications. Everyone gets gray hair It is considered a vanity science, she said. I am not an abnormally vain person My lab has picked the model that is the most appropriate method to investigate what happens to stem cells as we age.
The work has earned her a grant from the NIHs National Institute of Aging. A paper published by her lab in 2018 showed that MITF, a certain protein that is the master regulator turning on pigmentation genes also represses the innate immune system, according to UAB. The university said when Harris worked with the MITF-deficient mice with a virus, the melanocyte stem cells suffered and the mice got gray hair. The study was globally recognized, and featured in several publications.
Perhaps, in an individual who is healthy yet predisposed for gray hair, because they produce less MITF, getting an everyday viral infection is just enough to cause the decline of their melanocytes and melanocyte stem cells, leading to premature gray hair, Harris told UAB News.
Harris started working with the biotech startup when she was contacted by them last year. They were developing an experimental compound that would regrow hair, and they wanted to know if she would test it on her mice. Harris said she was skeptical, but she conducted a small trial.
It worked. Harris said when she tests gray-haired mice with the compound, she sees hair color come back.

And we can take these same mice, pluck the hair and when new hairs grow out they retain the higher level of pigmentation, suggesting this is permanent, she said. This compound is reprogramming the stem cells, taking them to a younger state, allowing them to start up again.
Harris and Joseph Palmer, one of her doctoral students, are also studying a theory that the melanocyte stem cells spend most of their time in a dormant state, and that the cells can possibly be stimulated.
(Spanish doctors in a study) suggested that some melanocyte stem cells are retained in gray hairs, Harris said. We thought that once you go gray the stem cells are all lost theres no going back. But presumably they can be reactivated. That study means, according to Harris, there may be therapies to reactive the cells, and the compound shes working with alongside the startup could be a promising way forward, according to UAB.
We have an opportunity with this company to find out what are the potential ways we can fix a broken system, Harris said. Were always looking at whats broken and rarely do we get to go in the other direction, towards tissue rejuvenation. So this is exciting.

Get rid of the ache within the nerves discovered with the following pointers, learn – Sahiwal Tv
By daniellenierenberg
Many folks around the globe will be seen troubled by ache within the veins. And many occasions, even after an excessive amount of therapy, this ache just isnt relieved. But within the coming days you possibly can do away with neuralgia fully, that too with none unwanted effects. Researchers on the University of Sydney have used human stem cells for excessive ache aid in mice.
->Now, theyre shifting in direction of human trials.
Greg Nelly, senior researcher on the Charles Perkins Center, stated that at occasions, extreme strain on the nerves causes them to get broken. For instance, carpal tunnel syndrome is the median nerve within the arms ( median nerve ) Due to extreme strain. As you possibly can think about, nerve accidents can result in insufferable neuropathic ache. There can also be no efficient therapy to alleviate ache in most sufferers.
Therefore, Nelly and colleagues on the University of Sydney developed an efficient remedy. Researchers have been capable of create pain-relieving neurons utilizing human stem cells.
Nelly stated that this success implies that for some sufferers affected by nerve ache, we are able to carry out pain-relieving implants from our cells, which might cease the ache.
In the examine, researchers collected stem cells from grownup blood samples. Then, used human-induced pluripotent stem cells (iPSCs) from the bone marrow to create pain-relieving cells within the laboratory.
To check the efficacy of the therapy, the staff injected neurons that abolished spinal ache in mice affected by extreme neuropathic ache. It was revealed that this therapy supplied full aid from ache to the mice with none unwanted effects.
Co-senior creator Dr. Leslie Caron stated that which means that transplant remedy is more likely to be an efficient and long-lasting therapy for neuropathic ache.
After shut therapy in mice, the University of Sydney staff is shifting ahead for extra in depth research in pigs. Within the subsequent 5 years, theyll check people that suffer from power ache.
Researchers stated {that a} move check in people can be an enormous success. This might point out the event of latest non-opioid, non-addictive ache administration methods for sufferers.
