Understanding interactions between the immune system and stem cells could pave the way for successful stem cell–based regenerative therapies.

The cells of the mammalian immune system do more than just fight off pathogens; they are also important players in stem cell function and are thus crucial for maintaining homeostasis and recovering from injury.

From DNA damage to cellular miscommunication, aging is a mysterious and multifarious process.

Tuberculosis bacteria find shelter from drugs and the body’s defenses in bone marrow stem cells.

The widespread bacteria known to manipulate host reproductive output can do so by ramping up stem cell division and consequent egg production in Drosophila.
