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
PDGFRA and DCN (decorin) are general ASPC/stromal markers broadly expressed across adipose stromal and progenitor cell populations. PPARG (peroxisome proliferator-activated receptor gamma) shows enriched expression in this specific subpopulation, distinguishing PPARG⁺ ASPCs from other ASPC subtypes. Together these markers identify a distinct ASPC subpopulation within the broader stromal compartment.
