Fig. 2From: Potential role of p21 Activated Kinase 1 (PAK1) in the invasion and motility of oral cancer cellsEffect of serum growth factors on PAK1 localization and its potential role in regulating actin cytoskeletal structures. HSC4 cells were serum starved for 48 h and treated with or without medium containing 10 % FBS for varying intervals of time. One set of plates were subjected to localization studies (a) while the second set was stained with Phalloidin 488 (b)Back to article page
