The US biomedical funding agency also hints at future restrictions on research involving human embryonic stem cells.

Although embryonic stem cells (ESCs) have been successfully derived from mice and rats, efforts to establish chimeric and germline-competent ESC lines in species beyond rodents have been unsuccessful.

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 ...

Senescence. It’s a beautiful-sounding word whose tones suggest it should be a perfume or an essential oil. But that’s not even close. Senescence is the loss of a cell’s power to divide and grow, thus ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

If infants are deprived of oxygen during delivery, they can experience brain damage that may have serious, lasting consequences. But a new stem cell treatment could prevent those neurological problems ...

Scientists at the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have discovered a previously unknown function of immune cells in the bone marrow. Embryonic macrophages—specialized ...

Most people have heard of stem cells. They are often described as "miracle" cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...
