Task: Intent Identification
Input (English): Mesenchymal stromal cells (MSCs) have great potential for use in cell-based therapies for restoration of structure and function of many tissue types including smooth muscle.', 'We compared proliferation, immunophenotype, differentiation capability and gene expression of bone marrow-derived MSCs expanded in different media containing human serum, plasma and platelet lysate in combination with commonly used protocols for myogenic, osteogenic, chondrogenic and adipogenic differentiation. Moreover, we developed a xenogenic-free protocol for myogenic differentiation of MSCs.', 'Expansion of MSCs in media complemented with serum, serum + platelet lysate or plasma + platelet lysate were multipotent because they differentiated toward four mesenchymal (myogenic, osteogenic, chondrogenic, adipogenic) lineages. Addition of platelet lysate to expansion media increased the proliferation of MSCs and their expression of CD146. Incubation of MSCs in medium containing human serum or plasma plus 5% human platelet lysate in combination with smooth muscle cell (SMC)-inducing growth factors TGFβ1, PDGF and ascorbic acid induced high expression of ACTA2, TAGLN, CNN1 and/or MYH11 contractile SMC markers. Osteogenic, adipogenic and chondrogenic differentiations served as controls.
