A new model of tiny human ovary organoids, or ovaroids, has been developed from stem cells, according to research presented ...

The Many Paths to Stem Cell-Based Embryo Models For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, ...

Today there are still logistical, ethical and legal limitations to using human embryos for research purposes, so scientists use alternative models including stem cell-based and animal models.

Destructive Human Embryonic Stem Cell Research—The term “destructive human embryonic stem cell research” means any research that involves the disaggregation of any human embryo for the ...
