Genes expected to be absent, or expressed at a notably low level, in these cells, and whose absence supports the assignment of this cell annotation.

Rationale
Perivascular cells (pericytes) were identified and annotated by Austin Reed based on RGS5+/PDGFRB+/ACTA2+ expression. These mural cells surround blood vessel endothelium and regulate vascular tone. The label 'Perivascular' was used by original contributing studies; CL:4033054 is the matched ontology term.
