Fig 1: Isolation and phenotypic characterization of nine porcine tissue-derived mesenchymal stromal cells (pMSCs). a Representative phase contrast images (50 × magnification) of Passage-0 cells, 10 days after isolation from the different porcine integumentary and connective tissues as specified. For all figures, Ab Abdominal, HL Hind limb, Hoof Hoof-associated superficial flexor tendon, Molar Molar-associated periodontal ligament, Muscle Gastrocnemius muscle b Phenotypic characterization of the pMSCs by gene transcripts of MSC (CD90, CD44, CD29, CD105), hematopoietic (CD11b) and endothelial (CD31) markers in Passage-2 cells cultured in growth media. ß-Actin was used for normalization of gene expression. Data presented as mean ± SEM (n = 3; *p < 0.05)
