Fig. 6. Distributions of percentages of time in which 900 LAMP1-GFP-positive organelles within wild-type (open bars) or pale ear (closed bars) fibroblasts moved at instant speeds of 0.78 µm/second or faster, in any direction (A), towards the nucleus (B), or away from the nucleus (C). Insets, comparable distributions obtained for 600 organelles labeled with the LAMP1-mGFP variant construct expressed in wild-type (open bars) or pale ear (closed bars) fibroblasts. Numbers on the x-axis denote bin limits; the last bin on the right of each panel includes all values greater than 24%.
