Human engraftment in the heart of NOD/SCID β2m null mice with AMI four weeks after transplantation of ALDH^hi Lin^- sorted human UCB cells. NOD/SCID β2m null mice with AMI were transplanted with ALDH^hiLin^- sorted human UCB cells. The lineage of human engrafting cells in selected organs was assessed by double staining for human specific β2m and CD45 (A-D) or CD31 (E-H) four weeks post transplantation. Nuclei: blue, CD45 and CD31: green, β2m: red. Scale bar represents 25 μm.
