Identification and characterization of ABCB1-mediated and non-apoptotic sebum secretion in differentiated hamster sebocytes

►Sebocyte differentiation results in the augmentation of sebum secretion. ►Differentiated sebocytes exhibit apoptosis-independent PS exposure. ►Increase in ATP level and transporter activity in differentiated sebocytes. ►ABCB1 expression is augmented in differentiated sebocytes. ►Involvement of ABCB1 in sebum secretion in differentiated sebocytes.
