Single-Cell Sequencing of Human Neural Organoids in a Model of Intracerebral Hemorrhage Reveals Temporally Dynamic Responses to Blood

Blood exposure induces transcriptomic changes in a temporal and cell type-specific manner, particularly mediated by astrocyte reactivity, angiogenesis, and impairment of neurogenesis. Early and complete removal of blood after 6 hours of blood exposure mitigates secondary neurotoxicity seen in 24-hour exposure to blood. Transcriptomic signatures of blood-mediated neurotoxicity may potentially be reversed by antiadrenergic, dopamine agonist, and vasodilatory mechanisms.
