Differentiation induction of the intermediate HDDPCs. (a) Time-line for differentiation induction of the HDDPC line P05 (13 days after the single transfection with Yamanaka’s four reprogramming factors) into neurogenic or osteoblastic lineage. (b) Neuronal cell induction 7 days after incubation in neurogenic medium. Nissl staining demonstrated that Nissl bodies are clearly discernible around the nucleus in the transfected cells (arrowed) in (iii), whereas no such bodies are discernible in the untransfected cells in (i). Bar = 500 μm (i) and (iii), 50 μm (ii) and (iv). (c) Osteoblastic cell induction 15 days after incubation in osteogenic medium. Von Kossa staining in (i) and (iii), and staining with Alizarin red-S in (ii) and (iv). Bar = 500 μm.
