Elevated fat content increases lipid droplets, but did not alter intestinal mucosal epithelium in zebrafish fed a HFD, MFD and LFD. TEM micrograph showing large lipid droplets accumulation in the apical epithelium of enterocytes and intraepithelial macrophages in HFD-C fed fish (A). Intact brush border in HFD-C fed fish, (B). Macrophages in MFD-C fed fish in contact with the cell membrane of infiltrated lymphocytes and granulocytes (C). Intraepithelial macrophages with typical features of phagocytic cells in LFD-C fed fish (D). Magnification of intra-epithelium granulocytes in MFD-C fed fish (E). L?=?lymphocyte; G?=?granulocyte; Asterisk?=?macrophage. Scale bars: A?=?5?µm, B?=?1?µm, C?=?10?µm, D?=?5?µm, E?=?2?µm.
