ARPE-19 cell phagocytosis on young, old and re-engineered BM. Phagocytosis was higher on young BM (123.6 ± 9.9 arbitrary units) versus older BM (54.9 ± 6.2 arbitrary units) (bar 1 versus bar 2; P < 0.001). Cleaning of old BM surface with detergent and sodium citrate (57.2 ± 8.5 arbitrary units) did not increase phagocytosis (bar 2 versus bar 3; P = 0.45). However, re-engineering of old BM by cleaning and coating with ECM proteins increased phagocytosis (83.5 ± 6.5 arbitrary units) compared with old BM (bar 2 versus bar 4; P = 0.009). Nevertheless, BM re-engineering did not improve phagocytosis in a manner similar to the high levels observed with young BM (bar 1 versus bar 4; P = 0.008). Det, detergent cleaning; ECM, addition of laminin, vitronectin, and fibronectin.
