“…On the other hand, BM constitute a rich source of EPC (Hristov et al, 2003). EPCs can initiate neovascularization (Asahara et al, 1997(Asahara et al, , 1999Schatteman and Awad, 2004) and their intraoperative isolation at high yields from BMAC is feasible (Kolvenbach et al, 2010;Essl et al, 2013). In addition, BMAC promotes in vivo bone regeneration by bringing platelets and growth factors such as PDGF-BB and VEGF to the injury site (Hernigou et al, 2005;Holmes et al, 2007;Zhong et al, 2012;Gary et al, 2013).…”
