Fig. 3From: GMP-compatible and xeno-free cultivation of mesenchymal progenitors derived from human-induced pluripotent stem cellsExpression of pluripotency markers. Immunohistochemical analysis showing lack of expression of pluripotency markers in induced pluripotent stem cell-derived mesodermal progenitors (line 1013A and BC1) cultured in different media at passages 6, 10, and 15. The nuclei are stained with 4′,6-diamidino-2-phenylindole (DAPI; blue). Scale bar = 20 μm. Abbreviations: MP, mesodermal progenitors; FBS, fetal bovine serum; HPL, human platelet lysate; P, passageBack to article page
