In addition, both IUGR- and Normal-MSCs expressed the classical MSC markers, CD44, CD90, and CD105 which levels were not statistically different (Figure 1D and Supplementary Table 1; P = 0.8, 0.4, 0.9, respectively), while the hematopoietic cell marker CD45 was not detected in either cell type. Here, CD44 is linked to fetal growth restriction.
