Stem cell plasticity A fertilized egg cell is totipotent and can produce both all the cells of the new individual as well as the tissues outside of the embryo, such as the placenta. The cells that ...

Stem cells can be unipotent, multipotent, pluripotent or totipotent, depending on the number of cell types to which they can give rise. Here the authors unveil the essential role of MCL-1 for ...

Some biologists see the beauty in their work. More than a few artists draw inspiration from the natural world. But stem cell researcher and artist linkurl:Ariel Ruiz ...

Our blood consists of many cell types that develop through different stages from a precursor type -- the blood stem cell. An international research team has now investigated the developmental pathways ...

After a sperm fertilizes an egg, the totipotent cell divides into a zygote ... up to seven days post fertilization. While stem cell-based embryo models greatly extend the ability to study this period ...

Stem cell research is still a new field within biology ... a two-cell sea urchin embryo are able to develop into a complete sea urchin, demonstrating the totipotency of these cells. Pluripotency of ...

Activating stem cells via molecular programming, rather than relying on random cell transplants, significantly enhances the success of regenerative treatments.

Not long ago, it was assumed that mammalian hearts were so differentiated that regeneration of cardiac tissue was not possible, but now an increasing amount of information suggests that the ...
