Abstract

Astrocytes, once considered passive support cells, are increasingly appreciated as dynamic regulators of neuronal development and function, in part via secreted factors. The extent to which they similarly regulate oligodendrocytes or proliferation and differentiation of oligodendrocyte progenitor cells (OPCs) is less understood. Here, we generated astrocytes from human pluripotent stem cells (hiPSC-Astros) and demonstrated that immature astrocytes, as opposed to mature ones, promote oligodendrogenesis in vitro. In the PVL mouse model of neonatal hypoxic/ischemic encephalopathy, associated with cerebral palsy in humans, transplanted immature hiPSC-Astros promoted myelinogenesis and behavioral outcome. We further identified TIMP-1 as a selectively upregulated component secreted from immature hiPSC-Astros. Accordingly, in the rat PVL model, intranasal administration of conditioned medium from immature hiPSC-Astros promoted oligodendrocyte maturation in a TIMP-1-dependent manner. Our findings suggest stage-specific developmental interactions between astroglia and oligodendroglia and have important therapeutic implications for promoting myelinogenesis.
