Development of new stem cell type may lead to advances in regenerative medicine
A team led by UT Southwestern has derived a new "intermediate" embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture dish. The findings, published online this week in Cell Stem Cell, could lead to a host of advances in basic biology, regenerative medicine, and reproductive technology.

CRISPR gene editing makes stem cells 'invisible' to immune system
UC San Francisco scientists have used the CRISPR-Cas9 gene-editing system to create the first pluripotent stem cells that are functionally "invisible" to the immune system, a feat of biological engineering that, in laboratory studies, prevented rejection of stem cell transplants. Because these "universal" stem cells can be manufactured more efficiently than stem cells tailor-made for each patient—the individualized approach that dominated earlier efforts—they bring the promise of regenerative medicine a step closer to reality.

Stem cell breakthrough could help cure type 1 diabetes
Scientists have edged one step closer to a major treatment for (and possibly cure for) type 1 diabetes. A UCSF team has claimed it's the first to turn human stem cells into the mature, insulin-producing cells that type 1 patients don't have. The key was to acknowledge a reality in the development of islets, or clusters of healthy beta cells (which generate insulin) in the pancreas. They separated partly differentiated pancreatic stem cells into islets, jumpstarting their development and leading to responses to blood sugar that more closely represented mature cells. Even alpha and delta cells grew more effectively, UCSF said.

Stem Cell Dental Implants Grow New Teeth In 2 Months!
A new groundbreaking discovery might make implants and dentures a thing of the past. This could change the lives of millions of people around the world. Most people who have dentures or implants have experienced some level of irritation or discomfort, pain, difficulty eating, or infections from their dental technology.

Lab-grown mini kidneys keep spawning rogue brain Cells
Brain cells are not something you want to find growing where you don’t expect them. But that’s the surprise that awaited a team from Washington University in St. Louis (WUSTL) when it analyzed the mini kidneys researchers have been growing from stem cells in the lab. Thankfully, the WUSTL team also found a way to prevent most of the brain cells from turning up in lab-grown mini kidneys — and the technique could prevent rogue cells from developing in other mini organs, too.

Lab-Grown Mini Kidneys 'Go Rogue,' Sprout Brain and Muscle Cells
Miniature lab-grown kidneys have been hiding something from the scientists who grew them. Instead of developing into different varieties of kidney cells, some of the cells took a different path and became brain and muscle cells. These simple mini kidneys — also known as kidney organoids — are grown from stem cells that are encouraged to develop into clusters of specific kidney cells. But it turns out that the "recipes" that encourage the development of specialized kidney cells were also cranking out cells from other organs, according to a new study.

Scientists Grow Full-Sized, Beating Human Hearts From Stem Cells
Of the 4,000 Americans waiting for heart transplants, only 2,500 will receive new hearts in the next year. Even for those lucky enough to get a transplant, the biggest risk is the their bodies will reject the new heart and launch a massive immune reaction against the foreign cells. To combat the problems of organ shortage and decrease the chance that a patient’s body will reject it, researchers have been working to create synthetic organs from patients’ own cells.

A man who received a stem-cell transplant for multiple sclerosis can walk and dance again after suffering from the disease for a decade
A man from Gloucester, England, can walk and dance for the first time in 10 years after receiving a revolutionary stem cell transplant for his multiple sclerosis, CBS News reported on Wednesday. Roy Palmer, a 49-year-old man who used a wheelchair, opted to undergo the treatment known as hematopoietic stem cell transplantation after watching a BBC program that showed the results of the treatment.

Test-tube rhinos? Experiment aims to save a vanishing species
Scientists say they’ve used human test-tube baby techniques to try to save the nearly extinct northern white rhino. In an improbable experiment, they are trying to resurrect an entire subspecies using dead males, two infertile remaining females, and some closely related southern white rhinos. And they say they also plan to use stem-cell technology to try to create a population of pure northern white rhinos in the lab.

Goodbye Dental Implants, Dentist Grows New Teeth in Just 9 Weeks
Dr. Jeremy Mao and his team from Columbia University were able to regrow teeth using stem cells as a ‘scaffold’ for the new tooth to grow over. Dr. Mao goes on to explain, “The missing tooth is replaced with stem cells from your body, and the tooth starts merging to the surrounding tissue on its own. This boosts the regeneration process and results in regrowth of the tooth in record time.” Essentially, this could mean the end of expensive dental surgeries used to replace damaged or missing teeth in the near future.

A new way to activate stem cells to make hair grow
UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.

Clues to aging found in stem cells' genomes
Little hints of immortality are lurking in the stem cells of fruit flies. Stem cells that produce sperm use a genetic trick to stay perpetually young across generations, researchers at the University of Michigan Life Sciences Institute have discovered. Certain sections of the fruit fly genome get shorter with age. But remarkably, some reproductive cells can repair the shrinkage, the researchers report in the journal eLife.
