Multipotent porcine mesenchymal stem cells (pMSC) are indispensable for research and therapeutic use. Derivation and culture media might affect the selection of MSC subpopulation and thus the differentiation potential of cells. In this study we evaluated the effects of MEM, aDMEM, M199, MEM/M199, aDMEM/M199 and MEM/aDMEM media on porcine bone marrow MSC derivation; pre-differentiation expression of ALP, COL1A1, SPP1 and BGLAP osteogenic marker genes at passage 5 and 10 pMSC; and differentiation potential of passage 5 pMSC. Morphological changes and matrix formation in osteogenic cells were evaluated by microscopical examination and calcium deposit in osteocytes was confirmed by Alizarin Red S staining. Results indicated media independent selection of different bone marrow MSC subpopulations with different surface marker gene expressions. Many pMSC subpopulations in different media had CD14+ expressing cells. We also observed basal media dependent changes in osteogenic markers expression and differentiation potential of pMSC. The MEM/aDMEM media grown pMSC showed best osteogenic differentiation potential. We thus recommended the testing of MEM/aDMEM mixed media in other species for pre-differentiation MSC culture that are intend...Continue Reading
