ABSTRACT
AIM:
To study the effect of mobilization of stem cells by exogenous recombinant human granulocyte-colony stimulating factor (rhG-CSF) on the repairing process of reendothelialization and neointima hyperplasy on ballon injured rat carotid arteries.METHODS:
Male Wistar rats were randomly divided into rhG-CSF group and NS+injury group. The animals were injected daily with 30 ?g/kg rhG-CSF or 0.9% NaCl for 7 days, then underwent balloon angioplasty of the common carotid arteries which were harvested and processed for scanning electron microscopy (SEM), Evans blue staining, morphometric analysis of endothelialization and neointimal formation at 1 h, 3 d, 5 d, 7 d, 14 d after injury. Immunohistochemistry for proliferation cell nuclear antigen (PCNA) and RT-PCR for eNOS mRNA were also conducted for evaluating the proliferation of cells of the vessel wall and the possible mechanism of the repairing.RESULTS:
SEM and Evan’s blue staining showed increased reendothelialization of the denuded vessels in rhG-CSF-treated animals compared with that NS+injury animals [(60.6?7.3)% vs (41.6?3.3)%,P
