Still images from representative movies of MDA-MB-231 cells expressing MT1-MMPpHLuorin (green)treated with control or RagC siRNA cultured on fluorescently labeled type I collagen (red). Right panels are galleries from video sequences (Video S1) documenting dynamics of exocytosis of MT1-MMPpHLuorinvesicles (inverted gray LUT, red arrows) on the collagen fibers (red). Double arrowheads, vesicle-to-plasma membrane connecting tether.
