ⅠII. Results
3.1 Under homeostatic conditions, ASC clusters in IAT and EAT display distinct
molecular properties and consist of three adipogenic stages 17
3.2 The adipogenic potential of ES1 and IS1 ASCs is primarily determined by their
intrinsic factors 27
3.3 In EAT, obesogenic stimuli enhance ES1 ASC proliferation through FGF and TGFβ
signaling, leading to de novo adipogenesis · 33
3.4 In obesity, EAT-specific SDC1+ regulate fibrosis and inflammation in a depot-
specific manner 39
3.5 During obesity, IAT specific CXCL14+ ASCs exert a suppressive effect on
monocyte infiltration 45
3.6 BST2high ASCs specific to IAT serve as precursors for beige adipocytes, and their
biogenesis is under the regulation of lymph nodes (LNs) 53
