  • Nature STAP stem cell studies retracted after more errors found

    Nature STAP stem cell studies retracted after more errors found

    Following months of controversy, editors at the scientific journal Nature have retracted two high-profile studies that purported to demonstrate a quick and simple way of making flexible stem cells without destroying embryos or tinkering with DNA. “Several critical errors have been found in our...

  • Scientists use cloning to make stem cells matched to two adults

    Scientists use cloning to make stem cells matched to two adults

    Scientists replicate a study that produced the world's first cloned human embryos and used them to make stem cells.

  • Scientists report another embryonic cloning success

    Scientists report another embryonic cloning success

    Scientists have taken skin cells from a woman suffering from type 1 diabetes, reprogrammed them into embryonic stem cells, and then converted those cells into insulin-producing cells in mice, according to a new study. The announcement, which comes soon after another stem cell success involving...

  • Researchers claim stem cell advance

    Researchers claim stem cell advance

    As new revelations further discredit a highly publicized Japanese study on the use of acid to create so-called STAP stem cells, scientists in the U.S. have quietly announced a research breakthrough that involves a more traditional means of producing the amazingly versatile cells. In a paper published...

  • Scientists use stem cells, mouse body to make a real human liver

    Scientists use stem cells, mouse body to make a real human liver

    Scientists trying to use stem cells to grow organs in the lab have been going about it the wrong way, Japanese researchers say. Instead of trying to make a fully functional organ to transplant into a patient, they should create an immature version and let it grow inside the patient’s body. The...

  • Team reportedly grows 'better quality' stem cells in live mice

    Team reportedly grows 'better quality' stem cells in live mice

    Researchers have reprogrammed cells inside living mice -- and have discovered that the pluripotent stem cells created in the process are even more flexible than those derived from embryos or grown in laboratory dishes. Someday the achievement might help scientists devise ways to treat human disease...

  • New method makes stem cells in about 30 minutes, scientists report

    New method makes stem cells in about 30 minutes, scientists report

    In a feat that experts say is a significant advance for regenerative medicine, scientists have discovered a surprisingly simple method for creating personalized stem cells that doesn’t involve human embryos or tinkering with DNA. Two studies published Wednesday in the journal Nature describe a...

  • Haruko Obokata says she created STAP stem cells "more than 200 times"

    Haruko Obokata says she created STAP stem cells "more than 200 times"

    The Japanese stem cell scientist who was accused of misconduct by her own research institution apologized Wednesday for making careless mistakes but insisted that her STAP stem cells are real. Haruko Obokata told reporters at a news conference that she “produced the STAP cells successfully more...

  • Scientist accused of manipulating data in STAP stem cell study

    Scientist accused of manipulating data in STAP stem cell study

    Research that made international headlines with a purported breakthrough in the creation of highly valuable stem cells has been found to contain falsified and manipulated data, according to a panel of Japanese investigators. At a news conference in Tokyo on Tuesday, the government's RIKEN research...

  • Pig bladders help wounded humans regrow damaged muscle, scientists say

    Pig bladders help wounded humans regrow damaged muscle, scientists say

    They had each lost slabs of muscle to bomb blasts or other physical traumas, then struggled to regain even partial function of their mangled legs. Some even considered amputation. After exhausting all conventional treatments, the five men volunteered for an experimental and seemingly outlandish...
