A ciliary junction following treatment with 10 Mg/ml cytochalasin A. The two cilifers making up the junction are attached by tufted junctional cilia. Bar = 1 nm. Transmission electron microscopy showed two additional effects of the cyto- chalasins on the J-cilia: the electron-dense band underlying the membrane of each J-cilium, on the side apposed to its mate, disappeared (Fig. 9); and the microtubules were poorly defined, and almost muddy in appearance following the administra- tion of either cytochalasin A or E (Fig. 10). The disruption of the microtubules occurred only at relatively high doses of cytochalasin A or E (about 15 /ig/ml),.
