Migration of BMDMSCs to the bleomycin-injured lungs.

<p><i>A</i>, Parabiont consisting of GFP-positive (GFP+) and wild-type (GFP-) mouse is shown. <i>B</i>, Flow cytometry analysis of leukocytes from the three sets of pooled blood of three parabionts (experiment using 9 parabiont pairs) showing roughly half of the cells show green fluorescence consistent with GFP positivity. <i>C</i>, Flow cytometry analysis of 200,000 cells prepared from three lungs of bleomycin- (black) or saline-treated (white) parabionts at day-21 are shown. Graphs compare percent of total cells that is GFP+(left) and percent of GFP+cells that is CD45-/CD44+/CD105+ (right). Error bars represent standard error of the mean (SEM).
