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 ...

In an advance for treating male infertility, researchers transplanted a patient with his own sperm-forming stem cells that ...

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 ...

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 ...

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 ...
