Welcome to Lab Dish, a First Opinion column on regenerative medicine from Paul Knoepfler. Twenty years ago, the use of human embryonic stem cells in research was among the most fiercely debated topics ...

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 ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Two of the first physical structures to form in the embryo are ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...
