(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) 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) Normal differentiation and induced reprogramming require the activation of target cell programs and silencing of donor cell programs. In reprogramming, the same factors are often used to reprogram many different donor cell types. As most developmental repressors, such as RE1-silencing transcription factor (REST) and Groucho (also known as TLE), are considered lineage-specific repressors, it remains unclear how identical combinations of transcription factors can silence so many different donor programs. more...

(Submitter supplied) How transcription factors (TFs) reprogram one cell lineage to another remains unclear. Here, we define chromatin accessibility changes induced by the proneural TF Ascl1 throughout conversion of fibroblasts into induced neuronal (iN) cells. Thousands of genomic loci are affected as early as 12 hours after Ascl1 induction. Surprisingly, over 80% of the accessibility changes occur between days 2 and 5 of the 3-week reprogramming process. more...

(Submitter supplied) Direct reprogramming from fibroblasts to neurons induces widespread cellular and transcriptional reconfigurations. In this study, we characterized global epigenomic changes during direct reprogramming using whole-genome base-resolution DNA methylome (mC) sequencing. We found that the pioneer transcription factor Ascl1 alone is sufficient for inducing robust non-CG methylation (mCH) accumulation in reprogrammed cells, but co-expression of Brn2 and Mytl1 was required to establish a global mCH pattern reminiscent of mature cortical neurons. more...

(Submitter supplied) Forced expression of ASCL1, Nurr1, Lmx1a, miRNA-124 and p53shRNA (ANLmp) in fibroblasts reprograms fibroblasts to induced dopaminergic neurons (iDA). While human lung fibroblasts can be converted rapidly and efficiently, iDA of dermal fibroblast is very unefficient and incompleted. To address this issue,  we performed time series RNAseq on both lung and dermal fibroblasts during the first several days of ANLmp induced neuron convertion. more...

(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...
