Proteomic Profiling of Ex Vivo Expanded CD34-Positive Haematopoetic Cells Derived from Umbilical Cord Blood

Figure 2

Principal component analysis (PCA) of CD34⁺ cells, showing that the three time points are distinct. Based on protein expression data, the largest variance was observed between day 0 and day 3; compared to this, the variation between day 3 and day 7 is smaller. Only little variances were observed between the three different cord blood donors.
