We previously derived a doxycycline-inducible (Tet-On) lineage-tracing model that allows for the indelible labeling of Pdgfrb-expressing perivascular cells in adipose tissue of adult mice (PdgfrbrtTA; TRE-Cre; Rosa26RmT/mG; herein, “MuralChaser mice”). Prior to exposing animals to doxycyline, all cells within the stromal-vascular fraction (SVF) of adult gonadal WAT (gWAT) express membrane tdTomato from the Rosa26 locus. Following 9 days of exposure to doxycycline-containing chow diet, Cre-mediated excision of the loxP-flanked tdTomato cassette occurs in Pdgfrb-expressing cells, and membrane-bound GFP (mGFP) expression is constitutively activated. We set out to test the hypothesis that Pdgfrb-expressing perivascular cells in gonadal visceral WAT of adult mice are heterogeneous, with subpopulations harboring functionally distinct phenotypes. To this end, we performed single cell RNA-sequencing of mGFP+ cells isolated from gWAT of lean (chow fed) 8 weeks-old male MuralChaser mice following 9 days of doxycycline exposure. Overall design: We pooled tdTomato- GFP+ cells from gonadal white adipose tissue (WAT) from 5 MuralChaser mice. Single cell library preparation was performed using the 10X Genomics Single Cell 3' v2 according to the manufacturer's instructions.
