Flow cytometric analysis of the first outgrowth collection from cardiac tissue.

<p>(A) A comparison of the proportion of the initial human and WK rat outgrowth cells expressing markers of CPC (c-Kit), endothelial (CD31, CD34) and mesenchymal (CD90) origin. (B) Flow cytometry dot plot of the initial cellular outgrowth harvested from WK rat tissue demonstrating co-segregation of mast cell antigen AA4 with CPC marker c-Kit. (C) Flow cytometry dot plots of the initial outgrowth harvested from WK rat tissue demonstrating the co-segregation and abundance of c-Kit and CD45.
