Abstract

The protracted timing required for oligodendrocyte differentiation from human pluripotent stem cells (hPSCs) has limited their use in disease modeling, drug screening, and cell therapy. In particular, the signals that drive oligodendrocyte specification and maturation after neural induction and ventral patterning remain poorly understood. Here, we present a protocol to derive human oligodendrocytes from hPSCs that is based solely on extrinsic cues, and we identify dual inhibition of BMP and Notch signaling as critical drivers of oligodendrocyte commitment and maturation. By day 42 of differentiation, up to 70% of the cells are positive for the oligodendrocyte marker O4, with minimal astrocyte contamination, and show robust expression of mature myelin markers including MBP, MOG, and MAG. These hPSC-derived oligodendrocytes closely match the molecular identity of primary fetal human oligodendrocytes as assessed by single-cell RNA sequencing and are functional as shown by in vitro myelination assays. In addition to the rapid generation of myelinating oligodendrocytes, the new protocol can be modularly adapted for the efficient production of PDGFR+ oligodendrocyte precursors or mixed glial populations containing AQP4+ astrocytes, thereby providing a cellular toolbox for the study of human glial lineages in translational applications.
