Hypothesis

CD34 could be used for identification and isolation of functional EPCs from mouse bone marrow.

Conclusion

Mouse CD34+ cells may represent a functional EPC population in bone marrow, which could benefit the investigation of therapeutic EPC biology.

Supporting Evidence

  • CD34+ cells showed the lowest EPC colony forming activity but exhibited the highest mRNA expression levels of endothelial markers.
  • CD34+ cells demonstrated a dramatic increase in immediate recruitment to the myocardium after myocardial infarction.
  • Cell retention and incorporation into the vasculature of the ischemic myocardium was significantly higher in the CD34+ cell-injected group.

Takeaway

Scientists found that a specific type of cell called CD34+ cells from mouse bone marrow can help heal the heart after injury by turning into blood vessel cells.

Methodology

CD34+ cells were isolated from mouse bone marrow using fluorescent activated cell sorting, and their properties were analyzed in vitro and in vivo.
