The expression of COX-2 involved in the transplanted keloid tissues after ADSC-CM treatment. (a, b, c, d) Digital photographs were taken for immunohistochemistry with COX-2 in the transplanted keloid tissues after being treated (magnification in a and c, ×200; in b and d, ×400). (e) The mRNA expression of COX-2 was detected by RT-PCR in transplanted keloid tissues after being treated. (f) The protein expression of COX-2 was examined by western blotting in transplanted keloid tissues after being treated. ^**p < 0.01, ^***p < 0.001 (ADSC-CM vs DMEM/F12), n = 6. ADSC-CM conditioned medium of adipose-derived stem cells, COX-2 cyclooxygenase-2, DMEM Dulbecco’s modified Eagle’s medium, F12 Ham’s F-12
