Abstract

After a brief exposure to agents that provoke phagocytosis, monocytic cells from patients with acute leukemia exhibit pentalaminar and septate membranous complexes. These structures connect plasma membranes of adjacent cells and join surfaces of approximating pseudopodia on the same cell; they also appear to be present in cortical areas of the cytoplasm.
