Extended Data Figure 1. Cellular composition of developing eWAT.

a) Cell clusters of merged transcriptional profiles of eWAT stromal-vascular cells harvested at P3 (n= 11553), P7 (n= 14538) and Adult (5-weeks old, n= 10442). Unsupervised clustering identifies distinct lineages corresponding to mesenchymal stromal cells (MSC), mesothelial cells, immune cells, endothelial cells, and committed preadipocytes (Preads).

b) Cell clusters from a) at each developmental stage.

c) Expression of selected signature genes defining each cell cluster depicted in a) and b).
