Observation of filamentous actin (F-actin) in the presence (lower) or absence (upper) of SPATC1L. F-actin in pEGFP vector-transfected control cells (mock; upper, green) and cells overexpressing SPATC1LΔC (lower, green) was visualized by staining using Phalloidin (red). White bar shows the length of transfected cell. Scale bar = 50 μm.
