Fig. 1From: Identification of a new plant extract for androgenic alopecia treatment using a non-radioactive human hair dermal papilla cell-based assayRT-PCR showing the expression of 5α-R and AR in HHDPCs. A 1 % agarose gel showing, from the top, the expression of 5α-R1 (5α-reductase type 1, 380 bp), AR (androgen receptor, 811 bp), 5α-R2 (5α-reductase type 2, 440 bp) and β-actin (584 bp) within passages 2, 4, 5 and 6 of HHDPCs. The 1-kb DNA ladder (L) shows the band sizes of 1 kb and 750, 500 and 250 bp from top downBack to article page
