Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Knoepfler is a professor of cell biology and human anatomy at UC Davis School of Medicine. Researchers are racing to engineer highly realistic human embryo models using stem cells in the lab. Some of ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

Human cell models may never be as good as the real thing, but we need these models to be as close as possible to understand how diseases develop and progress, and whether treatments are effective.

Development of patient-specific human organoids models for heart, liver, and kidney tissues ...

Animal models have long shaped how biomedical research is conducted. They have influenced how diseases are studied, how risks are assessed, and how potential treatments move from early discovery ...
