Abundance of CD73 and CD39 on leukocytes in blood and heart under basal conditions.

<p><b>A</b>: CD73⁺ and CD39⁺ cells per leukocyte population in cardiac tissue. <b>B</b>: CD73/CD39 surface density on CD73⁺/CD39⁺ cells per leukocyte population in cardiac tissue. <b>C</b>: CD73⁺ and CD39⁺ cells per leukocyte population in blood. <b>D</b>: CD73/CD39 surface density on CD73⁺/CD39⁺ cells per leukocyte population in blood. Only positive gated CD73 or CD39 cells (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0034730#pone-0034730-g003" target="_blank">Fig. 3A, 3C</a>) were considered for the calculation of antigen density. Values are means ± SD of n = 5 experiments. n.d. = not detectable.
