A, Schematic of the experimental design. B, Confocal immunofluorescence illustrates that the generation of CSCs from iPSCkit involves migration of CSCs from the embryoid bodies (EBs, solid line). C-D, high magnification of the area delineated by the inset in panel B, illustrates co-localization of EGFP with Nkx2.5 in the migrated CSC derivatives. E-F Gene-expression analysis during differentiation of iPSCkit to CSCs shows a dramatic upregulation in SDF1α and CXCR4. n=3; Scale bars, 100μm.
