Abstract (original English)
Mesenchymal stem cells (MSCs) usually lose their stemness during in vitro expansion as they are deprived of their niche environment. Cell-extracellular matrix (ECM) interaction is known to play important roles in preserving the stemness of the cells in their stem cell niche environment. Previously, coating with bone marrow MSC (BMSC)-derived ECM was found able to maintain the differentiation potential of in vitro cultured MSCs. This study aimed to determine if this ECM coating could also maintain the stemness of cultured murine adipose-derived stem cells (ASCs) using a regular culture flask as a control. Cells were expanded in ECM-coated and ECM-noncoated flasks for two and four passages and then harvested for various analyses. The results showed that ASCs exhibited fibroblast-like spindle morphology in ECM-coated flasks, whereas ASCs gradually spread and enlarged in the ECM-noncoated flasks. After three and five passages, both groups of cells exhibited similar cytokinetics in the MSC culture medium (MesenPRO RS™ Medium). However, when cultured in Dulbecco's modified Eagles medium (DMEM) plus 10% fetal bovine serum, coating group cells exhibited more potent proliferation than control group cells with a significant difference in both passages 3 and 5 (p<0.01). When seeded at low density (500 cells/10-cm dish), coating group cells formed significantly more and larger sized cell c
