The transcript levels of Sdc4 (syndecan 4), involved in ECM interactions and vasculogenesis, are increased, whereas those of F4/80 (or Adgre1), characteristic of macrophage infiltration, are decreased in the HF-fed LFABP−/− iWAT relative to WT (Figure 8c). This evidence concerns the gene ADGRE1 and hydrops fetalis.
