(Submitter supplied) Pro-neural transcription factors and small molecules can induce the transdifferentiation of fibroblasts into functional neurons; however, a molecular mechanism detailing the immediate-early events that catalyze this conversion has not been well defined. We previously demonstrated that NEUROG2, forskolin (F), and dorsomorphin (D) can induce functional neurons with high-efficiency. Here, we used this model to define the genetic and epigenetic events that initiate an acquisition of neuronal identity. more...

(Submitter supplied) Direct lineage reprogramming represents a remarkable conversion of cellular and transcriptome states. However, the intermediates through which individual cells progress are largely undefined. Here we used single cell RNA-seq at multiple time points to dissect direct reprogramming from mouse embryonic fibroblasts (MEFs) to induced neuronal (iN) cells. By deconstructing heterogeneity at each time point and ordering cells by transcriptome similarity rather than time we reconstructed a continuous reprogramming path. more...

(Submitter supplied) Human fibroblasts can be directly converted into cholinergic neurons by Neurogenin 2 (Neurog2 or NGN2) under the treatments of small molecules. Genome-wide analysis of gene expression was performed to examine the similarity of converted neurons to samples from human brain or spinal cord.

(Submitter supplied) Basic helix-loop-helix (bHLH) pioneer transcription factors Myod1 and Ascl1 are biochemically related but produce fundamentally different outcomes when expressed in fibroblasts: Myod1 produces muscle cells and Ascl1 induces neurons. Here, we sought to investigate the molecular mechanisms explaining the differential activity. Surprisingly, we found a large overlap in the overall binding patterns of Ascl1 and Myod1 in fibroblasts, with both transcription factors accessing both neuronal and myogenic targets. more...

(Submitter supplied) Reprogramming offers the possibility to study cell fate acquisitions otherwise difficult to address in vivo. By monitoring the dynamics of gene expression during direct reprogramming of astrocytes into different neuronal subtypes via the activation of Neurog2 and Ascl1, we demonstrate that these proneural factors control largely different neurogenic programs. Among the cascades induced, however, we identified a common subset of transcription factors required for both Neurog2- and Ascl1-induced reprogramming, and combinations of these factors comprising NeuroD4 were sufficient to generate functional neurons. more...

(Submitter supplied) Neuronal microRNAs miR-9/9* and miR-124 (miR-9/9*-124) direct cell-fate conversion of adult human fibroblasts to post-mitotic neurons and work in concert with additional transcription factors to enable the generation of discrete neuronal subtypes. Previously, the molecular events underlying the neurogenic switch mediated by microRNAs during neuronal reprogramming were unknown. Here, we systematically dissected the neurogenic state induced by miR-9/9*-124 alone. more...
