Current Research
Stem cell fates have a profound impact on health and disease progression. They are absolutely essential for their function in tissue development, maintenance, and disposition. The Scimè lab is focused on understanding the molecular, cellular, and physiological aspects for how metabolism controls stem cell fate choices, particularly in muscle and adipose tissue. This has implications for disorders such as type II diabetes, obesity, cancer, sarcopenia, and muscular dystrophy. At the cellular level adult stem cell fate choices of quiescence, activation, differentiation, and self-renewal are bio-energetically balanced through several metabolic pathways. We have found that altering these pathways impacts fate decisions. Ongoing studies are 1) to determine the role of cellular metabolism on stem cell fate choices in various tissue types, 2) to assess the role of whole-body stressors, such as exercise and diet on stem cell behavior, 3) to find the influence of altered metabolism on cancer stem function, and 4) to develop stem cell efficacy for regenerative medicine.
