stem cells

A report reveals that using bone marrow stem cells to treat heart disease is less promising than a decade of research has let on.

An acellular matrix can help guide stem cells to injury sites and regrow muscles in both mice and humans, a study finds.

Study confirms that somatic cell nuclear transfer, an alternate method of creating patient-specific pluripotent stem cells, can be used to reprogram adult cells.

An international team has created human embryonic stem cells from adult skin cells for the first time.

Researchers successfully transplant engineered esophagi into living rats.

Implanted into mice, lab-reared muscle made from stem cells can heal itself after an injury.  

Undergraduate students are more likely to enroll in engineering and biology since the last economic downturn, a survey finds.

An investigating committee at Japan’s RIKEN research center finds evidence of falsification and fabrication in two recent Nature papers that touted a new way to induce pluripotency.

A stem-cell researcher claims to have reproduced stimulus-triggered acquisition of pluripotency by following a revised protocol posted online last week.

Researchers work to improve the efficiency of cell therapy manufacturing, while developing procedures to ensure consistent quality.    
 

Stem cells supposedly derived by the new method of stimulus-induced acquisition of pluripotency may have come from mouse strains other than those claimed.

Scientists generate a new crop of stem cells that show therapeutic potential in mouse models of autoimmune diseases.

Researcher claims his failed attempt to reproduce stimulus-triggered acquisition of pluripotency was rejected for publication.

Nearly two months after researchers published papers showing that they could induce pluripotency with an external stressor, the work’s validity is still being challenged.

Questions of whether the stimulus-triggered acquisition of pluripotency papers will be retracted linger as RIKEN makes public its initial investigation, finding no evidence of scientific misconduct.

The stiffness of a culture substrate affects the fates of stem cells.  

One of the scientists behind the stimulus-triggered acquisition of pluripotency studies, which independent groups have had trouble reproducing, has requested that the papers be pulled from the literature.
