Abstract (original English)
Constant levels of homeobox transcription factor Prox1 expression are required throughout the life of lymphatic endothelial cells (LECs) to maintain their differentiated identity. Recent studies have demonstrated that using human LECs for cell transplantation therapy may improve secondary lymphedema in a nude rat model. However, the application is currently limited by the low yield of LECs. In this study, Prox1 was overexpressed in human adipose tissue-derived stem cells (hADSCs) by using the transfection of lentiviral vectors to induce the differentiation of hADSCs to LECs. After 14 days of Prox1 overexpression, flow cytometry analysis found that the expression of LEC-specific markers such as Podoplanin and VEGFR3, along with the endothelial cell (EC) marker CD31, on Prox1-overexpressed hADSCs was significantly increased; however, the expression of mesenchymal stem cell markers, such as CD29, CD44, and CD90, was substantially reduced. In addition, the mRNA levels of the LEC-specific markers, such as Prox1, Podoplanin, LYVE1, and VEGFR3, in Prox1-overexpressed hADSCs were significantly increased at day 7 and maintained a continuously increased expression level for 28 observation days, according to real-time reverse transcriptase-polymerase chain reaction results. Western blotting and immunofluorescence staining results further confirmed that overexpression of Prox1 in hADSCs si
