SLAMF1 and B-cell chronic lymphocytic leukemia: In contrast, in the csCD150+ CLL cases a low degree of CD150 colocalization was detected with markers of the ER (R = 0.23±0.05, R[r] = 0.19±0.10, n = 8), Golgi complex (R = 0.29±0.07, R[r] = 0.28±0.03, n = 8), endosomes (R = 0.30±0.03, R[r] = 0.29±0.05, n = 8) and lysosomes (R = 0.20±0.05, R[r] = 0.19±0.04, n = 8) (Fig 3B).
