Using stem cells and a bioreactor, researchers generated living embryos that survived for more than a week and began to develop internal organs.

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.

The members of a new advisory board to the NIH met for the first time and will weigh in on federal funding for grants that rely on donated tissue from abortions.

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.

External researchers funded by US federal grants can continue their experiments under tighter scrutiny.

The bipaternal pups died soon after birth, but mice with two mothers grew into fertile adults.

With just a molecular nudge, aggregates of embryonic stem cells take shape as a “gastroloid,” bearing the genetic hallmarks and spatial organization of early development.

The organ’s blood-pumping capacity improved with the infusion of cells, a study shows.

A trio of papers provide new insight into embryo development.

For the first time, a transplant of replacement tissue grown from stem cells has been shown to be feasible for patients with macular degeneration.

Scientists issue a call to reconsider the rules governing the creation of tissues, organs, and other structures made possible by recent advances in synthetic biology. 

Researchers report growing a mouse embryo using two types of early stem cells.

Report finds that pathologist involved in anonymous defamation case committed multiple acts of misconduct; growing eggs from stem cells; neutrophils’ role in metastasis; convergent evolution in birds

Researchers devise a technique for creating gametes from murine embryonic stem cells.

A look at the contributions of some of the prominent researchers who died this year

Researchers isolate an easy-to-manipulate, stable, and spatially distinct pluripotent cell type.  

Leroy Stevens, who discovered pluripotent embryonic stem cells in mice, has passed away at age 94.

Through cellular reprogramming, researchers have produced a novel pluripotent mouse stem cell in vitro.
