Change of protein expression for transplantation effect of human CD34+ hair follicle cells. Control mouse and transplantated mouse have the same expression level of total p38, pp38, ERK and AKT. But pERK expression levels were significant increased in transplantated mouse. Moreover, anti-apoptosis proteins, Bcl-2 was significant increased in transplantated mouse whereas proapoptosis proteun, Bax was significant decreased in transplantated mouse compared with control mouse.
