Expression of SP-C and CCSP in CD34pos cells. (A) Dot blot analysis from a representative animal (lamb #1744) showing the expression of SP-C and CCSP in the majority (>90%) of the CD34pos cells. (B) Combined results from 10 lambs showing the enrichment of SP-Cpos/CCSPpos cells in the CD34-selected cell fraction. The data are shown as the mean (± SD). **: p < 0.01. Before: before CD34 sorting; After: after CD34 sorting. (C) Expression of SP-C, CCSP, CD34, BMI1, OCT4, NANOG and GAPDH mRNAs in the unselected and in the CD34-selected cells measured by RT-PCR.
