Abstract:  The objective of this study was to simultaneously isolate and culture smooth muscle progenitor cell (SPC) and endothelial progenitor cell (EPC) from rabbit peripheral blood for use as cell sources in tissue engineering
of bladder and vascularization. In this study , SPC and EPC were simultaneously isolated and cultured from the peripheral blood of New Zealand Rabbit , and rabbit bladder smooth muscle (BSMC) were cultured and used as
smooth muscle cell positive control. The cells were cultured on coverslips and applied for uptake of Dil -AcLDL and binding of FITC -UEA - 1. Indirect immunofluorescent staining was performed to characterize the cultured cells using
monoclonal antibodies against smooth muscle actin (SMA) , Desmin , KDR , eNOS and vWF. Cell proliferation assay was also used to investigate the mitogenic effect of PDGF 2 BB and VEGF on both the SPC and EPC. Both the SPC
and EPC clones emerged after one week of culture. The SPC displayed fusiform shape with different size. The EPC showed the cobblestone morphology typical of endothelial cells. The BSMC cultured from rabbit exhibited the
elongated shape and hill and valleys pattern before confluence. The cluster of SPC and EPC were isolated and ubcultured using cloning cylinders , after which the highly purified SPC and EPC had been obtained. The SPC
display no ability of uptake of Dil -AcLDL and binding of FITC -UEA - 1 , while the EPC took - up Dil- AcLDL and showed FITC-UEA -1 binding affinity. In indirect immunofluorescent staining , the SPC demonstrated positive
staining for SMA , Desmin and KDR , while negative staining for eNOS and vWF. The EPC showed positive staining for KDR , eNOS and vWF , while negative staining for SMA and Desmin. The BSMC stained only positive for SMA
and Desmin. PDGF-BB had dose-dependent mitogenic effect on SPC , and VEGF had dose -dependent mitogenic effect on EPC. In conclusion , the highly purified SPC and EPC had been simultaneously isolated and cultured from rabbit
peripheral blood , and can be used as cell sources for tissue engineering of bladder and vascularization.
