简介:
Overview
This study presents a protocol for reprogramming human skin-derived fibroblasts into induced Neuronal Progenitor Cells (iNPCs) and their differentiation into induced Astrocytes (iAs). The method allows for rapid and reproducible generation of iNPCs and iAs, facilitating the study of neurological and neurodegenerative diseases.
