Following digestion, that only occurs in the phagolysosome (DV-III),
the membrane of these DVs undergoes extensive tubulation. These
tubules are ~45nm in diameter and arise from the cytosolic surface of
the DV-III in clumps of 3 to 6 tubules per clump. The tubules contain
a glycocalyx-like lining in their lumens which leaves only a 10nm
diameter opening in the center of the tubule (see Allen and Fok, J.
Cell Biol. 99:1955-1959, 1984). EM taken on 4/13/79 by R. Allen with
Hitachi HU11A TEM. Neg. 14,750X. Bar = 0.25µm.
