title: Differentiation of reprogrammed human adipose mesenchymal stem cells toward neural cells with defined transcription factors.
abstract: Somatic cell reprogramming may become a powerful approach to generate specific human cell types for cell-fate determination studies and potential transplantation therapies of neurological diseases. Here we report a reprogramming methodology with which human adipose stem cells (hADSCs) can be differentiated into neural cells. After being reprogrammed with polycistronic plasmid carrying defined factor OCT3/4, SOX2, KLF4 and c-MYC, and further treated with neural induce medium, the hADSCs switched to differentiate toward neural cell lineages. The generated cells had normal karyotypes and exogenous vector sequences were not inserted in the genomes. Therefore, this cell lineage conversion methodology bypasses the risk of mutation and gene instability, and provides a novel strategy to obtain patient-specific neural cells for basic research and therapeutic application.
