How a Silly Putty ingredient could advance stem cell therapies
The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.
Scientists smash barrier to growing organs from stem cells
(Phys.org) —Scientists at the University of Virginia School of Medicine have overcome one of the greatest challenges in biology and taken a major step toward being able to grow whole organs and tissues ...
Researchers discover ancient virus DNA remnants necessary for pluripotency in humans
Planaria deploy an ancient gene expression program in the course of organ regeneration
As multicellular creatures go, planaria worms are hardly glamorous. To say they appear rudimentary is more like it. These tiny aquatic flatworms that troll ponds and standing water resemble brown tubes equipped ...
Japan lab says stem cell research falsified (Update 3)
The finding that a lead researcher falsified data in a widely heralded stem-cell research paper is a setback for Japan's efforts to promote its advanced research, but also a symptom of the pressure for breakthroughs ...
Major breakthrough in stem cell manufacturing technology
Scientists at The University of Nottingham have developed a new substance which could simplify the manufacture of cell therapy in the pioneering world of regenerative medicine.
Embryonic stem cells: Reprogramming in early embryos
An Oregon Health & Science University scientist has been able to make embryonic stem cells from adult mouse body cells using the cytoplasm of two-cell embryos that were in the "interphase" stage of the cell ...
New technique for identifying gene-enhancers
An international team led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a new technique for identifying gene enhancers - sequences of DNA that act to amplify the ...
Proteins that control energy use necessary to form stem cells
Proteins that regulate energy metabolism are essential for stem cell formation, University of Washington researchers find.
Surprise: Lost stem cells naturally replaced by non-stem cells, fly research suggests
Johns Hopkins researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: When a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out ...
Only 1 in 7 Japanese scientists are women: study
Just a seventh of scientists in Japan are female, government figures show—a record high rate for the country, despite being the lowest rate of any developed nation.
Japan stem cell scientist stands by 'phoney' research (Update)
A young female scientist accused of fabricating data made a tearful apology live on Japanese television Wednesday for "mistakes" in her research, but insisted her ground-breaking conclusions on stem cells were accurate.
Analyzing living cells quickly and accurately
In order to investigate inflammation, tumors or stem cells, medical practitioners analyze living cells. Non-invasive optical procedures such as Raman spectroscopy accelerate this procedure. Researchers have ...
A safe, cheap and effective method for slow-freezing human stem cells
Human pluripotent stem cells (hPSCs) show great potential and versatility in regenerative medicine and new therapeutic approaches to fight disease. Patient-specific, individualized treatments using stem cells ...
