Cytoskeletal proteins. Cell painting showing the production of the cytoskeletal proteins F-actin and vimentin 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 (blue). Scale bar = 20 μm. Abbreviations: MP, mesodermal progenitors; FBS, fetal bovine serum; HPL, human platelet lysate; P, passage. Additional data are shown in Additional file 4: Figure S3
