Phosphatidyl-serine+ cargo transfer from Muller glia to microglia-Example I. 3-dimensional projection made from z-stacks shows the appearance of an apoptotic cell (YFP+) in the outer retina (yellow cell, white arrow). The cell is enwrapped by Muller cell processes (turquoise) but is transferred to a microglia cell (red) for terminal engulfment. Scale bar = 20 μm. Pertains to Figure 2A.
