Generation and characterization of iPS cell lines and differentiation into neurons. (A) Timeline of reprogramming skin fibroblasts to iPS cells. (B–E) Expression of pluripotency markers SSEA-4 and Sox2 in patient and control iPS cells and group means (+/− SEM). (D) Flowcytometry based analysis of control and patient cells. (F,G) Embryoid body cells expressing three germ layer markers: β III-tubulin (ectoderm), brachyury (mesoderm), GATA4 (endoderm). (H) Timeline of iPS cell differentiation to forebrain neurons. Brain-derived neurotrophic factor (B), ascorbic acid (A), glial cell-derived neurotrophic factor (G), DAPT (D), and dibutyryl cAMP (C). (I) Expression of neuronal differentiation markers and quantification of neurons immuno-labeled for β III-tubulin and FOXG1 expression. Scale bar: 50 microns.
