Cumulative proliferation assay based on the BrdU incorporation during seven days after injury.

<p><b>A.</b>Low magnification image showing the Star Track clonal labeling. <b>B.</b> Same image showing immunohistochemistry against GFP (grey) and BrdU (red). C–F. High magnification of areas highlighted in insets of A–B. <b>G–L.</b> Additional sections labeled with Star Track and GFP/BrdU immunohistochemistry. <b>G–H.</b> Images at low magnification showing the Star Track labeling. <b>I–L.</b> High magnification images of regions highlighted in insets. For each image, cells that are part of the same clone are encircled. Thick circles represent those cells that incorporated BrdU. Scale: A–B, G–H 400 µm; C–F, I–L 50 µm.
