Fig. 3. Confocal analysis of ß-catenin and N-cadherin distribution in subconfluent and confluent T98G and U373MG cells. The cells were plated onto poly-L-lysine-coated glass coverslips, fixed in 4% paraformaldehyde and immunostained. The arrows indicate ß-catenin- and N-cadherin-enriched spots in the T98G cells and lamellae and lamellipodia-like structures connecting adjacent cells in the U373MG cells. The arrowheads indicate filopodia-connecting neighbouring cells. Bar, 10 µm.
