Figure Lengend Snippet: Expression of cell surface makers in porcine embryonic fibroblasts (pEFs) from different breeds. (A) Chromogen immunocytochemistry staining (ICC) representative of pEFs from each breed. Scale bar represents 100 μm. Arrows mark positively labeled cells. (B) Representative immunocytochemical staining of SSEA-4 positive (+) cells in Danish Landrace and Yucatan pEFs. Scale bar represents 100 μm. (C) Mean cell populations (%) of SSEA-1, SSEA-4 and CD105 fibroblasts for pEFs from all breeds.

Figure Lengend Snippet: This data are based on 5 biologic replicates (A) The significantly differentially expressed Genes from the Volcano Plot built by comparing “SSEA-1+ vs SSEA-1-neg,” using Multiple Testing Correction: Benjamini and Hochberg False Discovery Rate. Differentially expressed genes were defined by Fold Difference: 1.2 and a P-value Cutoff: 0.05. (B) A gene condition tree heat map clustering of all genes was built by comparing “SSEA-1+ vs SSEA-1-neg.” Similarity Measurement, Distance. The clustering algorithm was performed using average linkage. (C) Gene condition tree heat map clustering of all genes built by comparing “SSEA-1+ vs SSEA-1-neg.” Discarded genes with no gene symbol annotation from the starting conditions. Rows are centered; unit variance scaling is applied to rows. Both rows and columns are clustered using correlation distance and average linkage.

Figure Lengend Snippet: Differentiation of magnetic sorted SSEA-1+ and SSEA-1neg D1 porcine embryonic fibroblasts (pEFSs) reveals enhanced differentiation into osteocytes and chondrocytes for SSEA-1+ populations. (A) Schematic representation of differentiation into mesenchymal cell lineages. (B) Both SSEA-1+ and SSEA-1neg cell fractions could undergo osteogenic and chrondrogenic differentiation following differentiation for 28 d. (C) Quantification of osteogenic differentiation was performed by reading absorbance levels of Alizarin red and revealed a higher propensity of differentiation in the SSEA-1+ cell fraction compared with the SSEA-1neg cell fraction. (D) Quantitative analyses of Alcian Blue revealed SSEA-1+ cells differentiated more proficiently than SSEA-1neg cells.
