Highly Cited Stem Cell Paper Pulled
Kerry Grens | Aug 5, 2014
The authors of a 2008
paper have retracted it after new data watered down the conclusions.
Light-Sensing Retina in a Dish
Anna Azvolinsky | Jun 10, 2014
From human induced pluripotent stem cells, researchers grow 3-D retinal tissue that can sense light.
Misconduct Found in STAP Case
Jef Akst | Apr 2, 2014
An investigating committee at Japan’s RIKEN research center finds evidence of falsification and fabrication in two recent
papers that touted a new way to induce pluripotency.
STAP Confusion Abounds
Jef Akst | Mar 31, 2014
Stem cells supposedly derived by the new method of stimulus-induced acquisition of pluripotency may have come from mouse strains other than those claimed.
STAP Drama Continues
Jef Akst | Mar 24, 2014
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.
A Twist of Fate
Jonathan Slack | Mar 1, 2014
Once believed to be irrevocably differentiated, mature cells are now proving to be flexible, able to switch identities with relatively simple manipulation.
Bird, Fish, and Fly Cells Reprogrammed
Kerry Grens | Sep 5, 2013
Using mouse genes, researchers partially transform differentiated, non-mammalian cells into pluripotent stem cells.
Long and Rocky Roads
Mary Beth Aberlin | Nov 1, 2012
From basic research to beneficial therapies
Karen Hopkin | Oct 1, 2012
Unwilling to accept the finality of terminal differentiation, Helen Blau has honed techniques that showcase the flexibility of cells to adopt different identities.
MicroRNAs Prevent Cell Reprogramming
Cristina Luiggi | Oct 24, 2011
A group of microRNAs can inhibit the formation of induced pluripotent stem cells, and may provide a target for more efficient reprogramming of somatic cells.
