Conclusion
This study showed human dermal mesenchymal fibroblasts taken from schizophrenic patients can be reprogrammed to hiPSCs, with potential to transformation to three germ layers with sufficient expression of relate molecular markers. This is the first steps to produce SCZ specific neural stem cells, which can be used in the assessment of cellular changes in schizophrenia and possible effects of antipsychotic agents. .
Methods
In the present study, we directly reprogrammed the isolated human ear dermal fibroblasts (HDFs) from schizophrenic patients into hiPSCs using some episomal agents in Matrigel-coated plates. The existence of pluripotency markers was confirmed by the immunocytochemistry (ICC) test and alkaline phosphatase protocol. We performed karyotype analysis to ensure the maintenance of the normal chromosomes.
Results
Analysis of colonies exhibited intense alkaline phosphatase engagement and Oct4, SSEA4, Nanog, and Tra-1-60. HiPSCs showed normal karyotypes and were potent to differentiate into ectoderm, endoderm, and mesoderm.
