The effect of Angiotensin I-converting enzyme (ACE) inhibitors on their own and in combination with the peptide AcSDKP on the proliferation of hematopoietic stem cells has been investigated. Hematopoietic stem cells from murine bone marrow induced into cell cycle following exposure to 2 Gy gamma-irradiation were incubated in vitro for up to 24 h in the presence of medium, captopril/lisinopril, AcSDKP, and AcSDKP with either ACE inhibitor. Hematopoietic stem cells were monitored using the high proliferative potential-colony forming cell-1 (HPP-CFC-1) population cloned in the presence of human IL-1 beta, murine IL-3, and murine M-CSF. No significant inhibitory effect was observed in the presence of AcSDKP on its own and AcSDKP in combination with lisinopril. However, there was a significant inhibition of stem cell cycling when AcSDKP and captopril were combined. This suggests that captopril inhibits AcSDKP breakdown better than lisinopril. The combination of AcSDKP and captopril also had an inhibitory effect on cell recruitment into S phase. The fact that a combination of AcSDKP and captopril switches cycling hematopoietic stem cells out of cycle indicates the importance of the N-active catalytic site of ACE in AcSDKP hydrolysis in vitro. Thus, AcSDKP in combination with appropriate ACE inhibitors may be of use in regulating the proliferation of hematopoietic stem cells in vitro.
