Embryonic stem cells have the potential to differentiate into any type of cell in the human body. Once differentiated though, the newly minted somatic cells live out the rest of their days as that specific cell type and never ...

A process called sporulation that helps the dangerous bacterium Clostridium difficile (C. difficile) to survive inhospitable conditions and spread is regulated by epigenetics, factors that affect gene expression beyond the ...
