Fig. 6. DIC microscopy micrographs of untreated L929 fibroblasts (a), L929 fibroblasts incubated for 3 hours at 37°C in the presence of 2.5 µg/ml nocodazole (b), and L929 fibroblasts incubated for 3 hours at 37°C in the presence of 2.5 µg/ml nocodazole and subsequently treated with 50 µM DLPC (<2% of endogenous phospholipids) for 3 minutes (c). Cells were then fixed for microscopic observations. Bars, 10 µm.
