Morphologic analysis of the NEC and CD34+ sorted subfractions from previously frozen maternal and nongravida PB samples. Fractions were sorted by FACS and cytocentrifuged at 500 rpm for 5 minutes onto slides and differentially stained with May-Grünwald-Giemsa. No less than 100 cells were analyzed by light microscopy to give a differential. The mean values from three and four independent experiments from maternal and nongravida PB, respectively, are presented.
