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, ...

Scientists have long dreamed of plucking those naive cells from a young human ... clinics and establishing the world's first human embryonic stem cell line, he and other scientists got a lot ...

These are found in an early embryo. These cells are able to divide continuously. Embryonic stem cells are pluripotent. This means that all of the genes in an embryonic stem cell can be expressed ...
