Novel Direct Conversion of Microglia to Neurons.

Direct cell reprogramming, the process by which a somatic cell is converted to another cell type, can potentially circumvent epigenetic changes and proliferative stages resulting from de-differentiation. Recently, Matsuda et al. (Pioneer factor NeuroD1 rearranges transcriptional and epigenetic profiles to execute microglia-neuron conversion; Neuronin in press) demonstrated that expression of transcription factor NeuroD1 can convert mouse microglia to neurons, both in vitro and in vivo.
