Intact U2OS or RPE1 cells (b) or the cells treated with EDTA to acquire a spherical morphology (c) were subjected to immunostaining and confocal microscopy. A single optical section is shown for the cells in (c). ¦ÂII spectrin served as cell cortex marker. Arrows point to typical regions positive for both proteins. Nuclear DNA was visualized by DAPI. d Subcellular localization of GFP-abLIM1 in U2OS cells. Arrows indicate regions apparently positive for GFP-abLIM1, ¦ÂII spectrin, and F-actin. Note that highly expressed GFP-abLIM1 displayed colocalization with actin bundles. e Overexpressed GFP-abLIM1 colocalized with cortical actin bundles. Shown are confocal micrographs of a representative RPE1 cell. The two dimensional (2D) images were projected from all optical sections or just Paxillin-free top sections. The 3D reconstructed image is shown as the top view, accompanied with side views of the indicated positions. Paxillin signals mark the bottom side of the cell. f GFP failed to show associations with F-actin in RPE1 cells. Note that the cell is also abundant in cortical actin bundle %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6056535/
