Methods Eukaryotic expression plasmid pCMVCD was constructed , and identified by re2 striction endoenzyme digestion. CD gene was transfected into NSCs from new2born Wistar rats using Lipofec2tamine2000. Positive clones (named NSCs/ CD cells) were screened by G418 presence. 52Fluorocytosine (52FC) ad2ministration of different concentrations were incubated with NSCs/ CD cells. NSCs/ CD cells viability ratios were mea2 sured by MTT assay.
