Abstract:
Reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) by overexpression of the transcription factors OCT4, SOX2, KLF4, and c-Myc holds great promise for the development of personalized cell replacement therapies. In an attempt to minimize the risk of chromosomal disruption and to simplify reprogramming, several studies demonstrated that a reduced set of reprogramming factors is sufficient to generate iPSC. We recently showed that a reduction of reprogramming factors in murine cells not only reduces reprogramming efficiency but also may worsen subsequent differentiation. To prove whether this is also true for human cells, we compared the efficiency of neuronal differentiation of iPSC generated from fetal human neural stem cells with either one (OCT4; h i P S C 1 F - N S C ) or two (OCT4, KLF4; h i P S C 2 F - N S C ) reprogramming factors with iPSC produced from human fibroblasts using three ( h i P S C 3 F - F I B ) or four reprogramming factors ( h i P S C 4 F - F I B ). After four weeks of coculture with PA6 stromal cells, neuronal differentiation of h i P S C 1 F - N S C and h i P S C 2 F - N S C was as efficient as i P S C 3 F - F I B or i P S C 4 F - F I B . We conclude that a reduction of reprogramming factors in human cells does reduce reprogramming efficiency but does not alter subsequent differentiation into neural lineages. This is of importance for the development of future application of iPSC in cell replacement therapies.
