Barbar et al. identify CD49f as a novel surface marker expressed by human astrocytes that can purify hiPSC-astrocytes and primary fetal astrocytes. CD49f+ hiPSC-astrocytes respond to pro-inflammatory stimuli and become A1 reactive astrocytes, which are dysfunctional and secrete neurotoxic factors that induce apoptosis in human and rodent neurons.
