Cardiomyocytes made from iPSCs aboard the International Space Station had upregulated mitochondrial functioning.

Several early-stage clinical trials indicate that implanting patients with the cells is safe. But whether they can alleviate neurological problems remains to be seen.

New, unpublished results show some of the cells produce new neurons for up to 90 days, much longer than a previously identified set of neural stem cells that only generate neurons for a month or two.

Extended pluripotent stem cells from mice can self-organize to form blastocyst-like structures called blastoids that enable a closer look at early mammalian development.

A new method helps neural stem cells form synaptic connections, thereby restoring lost brain function.

The new policy will increase scrutiny and pressure on stem cell clinics, according to industry experts.

A Chicago-based center that has long operated a clinical trial program for stem cell therapies, has stopped recruiting further patients as its chief, Richard Burt, leaves for a research sabbatical.

The researchers aim to grow transplantable human organs from primate embryos.

So far, the only evidence that treatments like this one work is anecdotal.
