GLI1⁺ perivascular cells in angiogenesis and vascular remodeling: mechanisms and disease relevance
Glioma-associated oncogene family zinc finger 1 (GLI1) encodes a major transcriptional effector of Hedgehog (HH) signaling. In adult tissues, GLI1 expression also marks perivascular mesenchymal populations with progenitor-like and injury-responsive properties. Over the past decade, lineage-tracing and single-cell stu...
