BM-MSC from SCD and NS patients displayed typical mesenchymal markers equally positive for CD29, CD90, and CD105 (Figure 4(c)) while lacking expression of hematopoietic markers (HLA-DR, CD14, CD34, and CD45) (data not shown) over the first six passages, in accordance with the minimal criteria for BM-MSC [37]. This evidence concerns the gene CD34 and Schnyder corneal dystrophy.
