ABSTRACT
Objective@#To investigate the effects of PRX-2 gene on phenotype changes in epidermal stem cells differentiating into sweat gland cells.@*Methods@#Epidermal stem cells and sweat gland cells separated and cultured from healthy foreskin and adult full-thick skin respectively, were identified by immunofluorescence staining. Lentiviral vector-mediated overexpression and knockdown of PRX-2 gene in epidermal stem cells were performed respectively, with empty vector-mediated epidermal stem cells as a control group. Overexpression、blank control and knowdown group′s PRX-2 expressions in gene and protein levels were detected using RT-PCR and Western blot technology. The ESCs of each group were co-cultured with sweat gland cells through transwell plate, and the expressions of CEA and β1 integrin in epidermal stem cells were determined by flow cytometry before and after co-culturing.@*Results@#Epidermal stem cells and sweat gland cells were in line with their respective specific antigens. Before co-cultured, epidermal stem cells highly expressed β1 integrin (98.69±0.67)%, hardly expressed CEA (6.20±3.15)%. After co-cultured, β1 integrin expression levels were showed as knockdown group (19.30±0.53)%<blank control group (65.77±2.32)% <overexpress group (92.63±10.97)%, and CEA expression levels as knockdown (95.43±2.36)%> blank control group (51.20±0.79)%> overexpress group (45.91±0.93)%. There had significant differences between those of each two groups.@*Conclusions@#PRX-2 gene can inhibit the phenotypic change of Epidermal Stem Cells differentiating into Sweat Gland Cells and improve the ability to maintain their own specific antigens.
