摘要: Mesenchymal stem cells (MSCs) have a great capacity for self-renewal while still maintaining their multipotency, and can differentiate into variety of cell types. The delivery genes to site injury is current interesting field gene therapy. In the present study, we describe nonviral carrier, glycol chitosan-methyl acrylate-polyethylenimine (GMP) polymer targeted towards human adipose-derived mesenchymal (AD-MSCs). Transfection efficiency, using luciferase (Luc) pDNA encoding enhanced green fluorescent protein (EGFP), along with cytotoxicity assays, were performed in AD-MSCs. results show that transfection efficiency GMP was similar PEI25kD, lower. Moreover, AD-MSCs treated polymer/pDNA polyplex its cellular uptake distribution analyzed by flow cytometry confocal microscopy. Furthermore, endosomal escape analysis LysoTracker Red, found conjugated could from endosome cytosol. Human maintained potential osteogenic differentiation phenotypic expression based on analysis. study demonstrates be used as targeted-delivery carrier effective delivery.
