Affect of iPSC Passage Number on Neuronal Differentiation

Project description:Induced pluripotent stem cells (iPSCs) are a valuable resource for neurological disease-modeling and drug discovery, due to their ability to differentiate into neurons reflecting the genetics of the patient from which they are derived. iPSC-derived cultures, however, are highly variable due to differences in culture conditions. We investigated the effect of iPSC passage number on differentiation to optimize the generation of functional, mature sensory neurons (iPSC-dSNs). Three iPSC lines were differentiated into iPSC-dSNs at passage numbers within each of the following ranges: low (LP; 5-10), middle (MP; 20-26), and high (HP; 30-38). Morphology and pluripotency of the parent iPSCs were assessed prior to differentiation at each passage number. iPSC-dSNs were evaluated based on electrophysiological properties and expression of key neuronal markers. All iPSC lines displayed the same morphology and were similarly pluripotent across passage numbers. iPSC-dSNs were also morphologically comparable across passage numbers. However, the expression levels of neuronal markers and an analysis of sodium channel function indicated greater maturity in LP iPSC-dSNs. Our results demonstrate that lower passage numbers may be better suited for differentiation into peripheral sensory neurons. Further studies are warranted to elucidate factors that may contribute to the variability associated with iPSC passage number.

Lineage conversion induced by pluripotency factors involves transient passage through an iPSC stage

Project description:Brief expression of pluripotency-associated factors such as Oct4, Klf4, Sox2 and c-Myc (OKSM), in combination with differentiation-inducing signals, has been reported to trigger transdifferentiation of fibroblasts into other cell types. Here we show that OKSM expression in mouse fibroblasts gives rise to both induced pluripotent stem cells (iPSCs) and induced neural stem cells (iNSCs) under conditions previously shown to induce only iNSCs. Fibroblast-derived iNSC colonies silenced retroviral transgenes and reactivated silenced X chromosomes, both hallmarks of pluripotent stem cells. Moreover, lineage tracing with an Oct4-CreER labeling system demonstrated that virtually all iNSC colonies originated from cells transiently expressing Oct4, whereas ablation of Oct4+ cells prevented iNSC formation. Lastly, an alternative transdifferentiation cocktail that lacks Oct4 and was reportedly unable to support induced pluripotency yielded iPSCs and iNSCs carrying the Oct4-CreER-derived lineage label. Together, these data suggest that iNSC generation from fibroblasts using OKSM and other pluripotency-related reprogramming factors requires passage through a transient iPSC state.

Pluripotency factor-induced lineage conversion involves transient passage through an iPS cell stage

Project description:Brief expression of pluripotency-associated factors such as OCT4, KLF4, SOX2 and c-MYC (OKSM), in combination with differentiation-inducing signals, was reported to trigger transdifferentiation of fibroblasts into alternative cell types. Here, we show that OKSM expression gives rise to both induced pluripotent stem cells (iPSCs) and iNSCs under conditions that were previously shown to induce only NSC transdifferentiation. Fibroblast-derived iNSC colonies silenced retroviral transgenes and reactivated silenced X chromosomes, both hallmarks of pluripotent stem cells. Moreover, lineage tracing via an Oct4-CreER labeling system demonstrated that virtually all iNSC colonies originate from cells transiently expressing Oct4, whereas ablation of Oct4-positive cells prevented iNSC formation. Lastly, use of an alternative transdifferentiation cocktail that lacks OCT4 and was reportedly unable to support induced pluripotency, yielded iPSCs and iNSCs carrying the Oct4-CreER-derived lineage label. Together, these data suggest that iNSC generation using OKSM and related reprogramming factors requires passage through a transient iPSC state. 5 samples were anlyzed in total, 2 induced pluripotent stem cells (iPSCs), 1 neural stem cells (NSCs) and 2 induced NSCs (iNSCs)
