Hematopoietic stem cells (HSCs) are essential for the lifelong production of blood cells. Our research demonstrated that specific molecular signals, like Vitamin A, keep HSCs in a sleep-like, dormant state protecting them from exhaustion and maintaining their long-term differentiation potential. As a reaction to stress, such as blood loss or infections, dormant HSCs are activated in order to regenerate the blood system in a quick manner. We are investigating the mechanisms responsible for the resting state to develop new therapeutic approaches for the treatment of blood-related diseases.
