Differentiation of hOB-iPSCs into trilineages. (a) hOB-iPSC embryoid bodies (EBs) labeled with antibodies for cytoplasmic germ-layer markers, β-III tubulin (β-III; ectoderm), AFP (endoderm), and SMA (mesoderm). (b) hOB-iPSC EBs labeled with antibodies for germ-layer transcription factors, HAND1 (mesoderm), Sox1 (ectoderm), and Sox17 (endoderm). (c) Undetectable staining for pluripotent cells with TRA-1-60. Scale bars = 40 μm.
