Quiescent satellite cells (SCs) display heterogeneous expression of Pax3 which has been shown to play a role in proliferation and myogenic determination. p53 is known to be involved in the regulation of quiescence, self-renewal, cell fate, and cellular senescence. SCs from the diaphragm lose their myogenic fate at a much higher rate than SCs from the hindlimb. Early results show that p53 displays differential activity in the diaphragm versus the limb SCs. Indeed, when Pax3 is overexpressed in C2C12 cells p53 is destabilized.

The Balmain labs' main research interests have been the elucidation of the molecular mechanisms of multistage carcinogenesis, with particular emphasis on mouse models of chemically induced skin tumor development.

Palmer Lab Summary: Neural precursor cells (NPC) possess the ability differentiate into mature neurons. Transplantation of NPCs may help to alleviate conditions of diminished neurogenesis and neurodegenerative
disease by providing a source of new neurons. My work is focused on understanding how the immune system reacts to transplanted NPCs in a murine model.

The Denbesten lab focuses on whole‐tooth regeneration, both for direct clinical application and as a model for organogenesis in general. A major hindrance to the goal of tooth regeneration is that Ameloblasts (the cells
responsible for secreting proteins which direct the formation of tooth enamel) are no longer present after teeth have erupted. My lab is currently engaged in efforts to identify the factors capable of promoting Ameloblast differentiation from human embryonic stem cells.
