31. These studies also hope to expand research into regenerative medicine models and stem cell differentiation . 32. GATA-3 was shown to directly regulate luminal cell differentiation in mouse models of breast cancer. 33. The Wnt pathway plays a key role in embryonic development, cell differentiation and cell proliferation. 34. However, Pax7 is expressed prominently after satellite cell differentiation . 35. Probably Hsp27 among other chaperones is involved in the process of cell differentiation . 36. In this context Shh acts as a morphogen-it induces cell differentiation dependent on its concentration. 37. Members of the protein tyrosine phosphatase superfamily cooperate with protein kinases to regulate cell differentiation . 38. This indicates the possibility of TMEM143 participation in lipid metabolic pathways and lipid cell differentiation 39. In the PNS ( where NGF, NT-3 and cell differentiation and function rather than survival. 40. Numb s primary function in cell differentiation is as an inhibitor of DSL family ligands.
