How do a couple of universally expressed proteins in stem cells and developing embryos influence an individual cell's ultimate fate—whether it ultimately becomes, for example, a retinal cell, a heart muscle cell, or a stomach ...

A matter of concentration

Plants can grow whole new organs with the help of pluripotent stem cells throughout their entire lives. When necessary, these stem cells can develop into any type of cell within an organism. The biologist Prof. Dr. Thomas ...

How intestinal cells renew themselves

The intestine must be able to renew itself to recover from environmental insults like bacterial infections. This renewal is made possible by a small number of intestinal stem cells which divide and produce daughter cells ...

Complete skin regeneration system of fish unraveled

Fish and amphibians such as newts can perfectly regenerate tissue without scar tissue in the event that they lose organs such as their limbs. Studying the mechanisms of regeneration and homeostasis of tissues has potential ...

Structure of a stem cell niche

Stem cells—specialized cells that can self-renew and generate functional cells—maintain adult tissues. They reside in a specialized microenvironment, known as a niche, that regulates their self-renewal and activities. ...
