Figure 7. The internal structure of BM-MSC and RPE cell phagocytic activity on transmission electron microscopy. (Row 1) Bone marrow mesenchymal stem cells (BM-MSCs) phagocytizing the photoreceptor outer segment (POS) at 24 h at different magnifications. (Row 2) BM-MSCs phagocytizing POS for 48 h. The layer-like substance was smaller than at 24 h. (Row 3) RPE cells phagocytizing the POS for 48 h. The layer-like substance was less and more loose at 48 h than at 24 h.
