When we performed Masson’s trichrome staining to detect fibrotic areas, the level of fibrosis was significantly higher in the HF-ODX group than in the HD-Naïve (1.52 fold, p < 0.05) and HD-ODXT (3.00 fold, p < 0.05) groups, similar to the TGF-β mRNA levels (Figure 2D). The gene discussed is TGFB1; the disease is hydrops fetalis.
