Effects of UV treatment and ALN immersion on cellular differentiation in HGFs in the M, MUV, MAN, and MUVAN groups. RT-PCR data indicate the relative mRNA expression of (a) integrin-β1, (b) type I collagen, (c) type III collagen, (d) fibronectin, and (e) laminin5 after 24 h of culture. Data are expressed as means ± S.E.M. (n = 5). *P < 0.05 for comparisons among the groups. The asterisks indicate statistically significant differences between the groups.
