While regeneration has long been the domain of colonial tunicates, a solitary species of sea squirt was able to regenerate into multiple, fully functional individuals within a month of being cut up.

Researchers insert functioning cone photoreceptors into the retinas of mice with advanced eye disease, improving their vision.

Human stem cells injected into early monkey embryos proliferate and contribute to multiple cell lineages over 20 days of embryonic development.

From his student days in veterinary medicine in Ethiopia to running a lab on metastasis at MD Anderson Cancer Center, Debeb has a passion for understanding how living things work.

Two new papers describe the generation of so-called blastoids, which could avoid the use of embryonic cells and make studying early human development much more accessible.

Researchers determined that when introduced into damaged mouse or donated human livers, these lab-grown tissues could integrate into bile ducts and function normally.

The state will take on additional debt to finance CIRM, which will now continue to fund stem cell research, training, and clinical trials.

Infusions of donor T cells to fight the cancer often fail, but sodium bicarbonate can counter lactic acid produced by leukemia cells, potentially improving remission rates in mice and humans.

Cancer therapies could potentially be more effective if their development took into account the cells that give rise to tumor-fighting cells.

Better understanding the CD8+ T cells already present in tumors could be key to making immunotherapies work for more patients.

As the first clinical data become available on treating coronavirus patients with the cells, scientists are equivocal about the rationale for the intervention.

The controversial oogonial stem cells eluded a team of Swedish researchers who mapped high-quality tissue samples of the human ovary, prompting more questions about the cells’ existence.  

The Trump administration’s changes to policy involving material donated from abortions have led scientists to adjust their research projects or seek alternative sources of funding.
