RNA key in helping stem cells know what to become
Look deep inside our cells, and you'll find that each has an identical genome -a complete set of genes that provides the instructions for our cells' form and function.

In regenerative medicine, scientists aim to significantly advance techniques that can control stem cell lineage commitment. For example, mechanical stimulation of mesenchymal stem cells (MSCs) at the nanoscale can activate ...
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 ...
