abstract = {Germinal matrix hemorrhage (GMH) is a devastating
neurodevelopmental condition affecting preterm infants, but
why blood vessels in this brain region are vulnerable to
rupture remains unknown. Here we show that microglia in
prenatal mouse and human brain interact with nascent
vasculature in an age-dependent manner and that ablation of
these cells in mice reduces angiogenesis in the ganglionic
eminences, which correspond to the human germinal matrix.
Consistent with these findings, single-cell transcriptomics
and flow cytometry show that distinct subsets of CD45+ cells
from control preterm infants employ diverse signaling
mechanisms to promote vascular network formation. In
contrast, CD45+ cells from infants with GMH harbor activated
neutrophils and monocytes that produce proinflammatory
factors, including azurocidin 1, elastase and CXCL16, to
disrupt vascular integrity and cause hemorrhage in
ganglionic eminences. These results underscore the brain's
innate immune cells in region-specific angiogenesis and how
aberrant activation of these immune cells promotes GMH in
preterm infants.},
