Fig. 4B illustrates depot-specific expression of genes at days 0, 4, and 7. We did not find any statistically significant difference in gene expression between OM and SC at these time points. We then compared expression of FAP, DPP4, MMP1 and TGFβ1 in OM and SC adipose tissues, preadipocytes and DFAT cells. Except for MMP1, all genes were expressed in adipose tissues and all four were expressed in preadipocytes. Fig. 4C shows expression in DFAT cells at day 12. This evidence concerns the gene DPP4 and ocular melanoma.
