Differences in susceptibility to apoptotic stimuli depending on cell differentiation status and direction were shown in muscle-derived stem cells. The results prove that protein kinase Akt and ERK, p38, MAPK promote survival of differentiated cells during apoptotic treatments. The role of JNK kinase in apoptosis may depend on cell differentiation stage and type of apoptotic stimuli. We have proved that JNK has a potential to regulate pro- and antiapoptotic Bcl-2 family protein level in this cells.
