Cell death and apoptosis analysis of LPS stimulated HaCaTs, HDMECs and L929 alone or co-cultured with TCs by Annexin V -FITC/PI double staining in 48 h. a Representative pictures of cell apoptosis phases for LPS stimulated HaCaTs, HDMECs and L929 alone or co-cultured with TCs. b–e The comparison of death, early apoptosis, late apoptosis, and whole apoptosis in LPS stimulated HaCaTs, HDMECs and L929 alone or co-cultured with TCs. ^*P < 0.05 compared with vehicle; ^#P < 0.05 compared with LPS treated group; ^nsP > 0.05, LPS treated group compared with vehicle or TCs-cocultured group compared with LPS-induced group. Data are expressed as the mean ± SEM
