Comparative analysis of expression of mesenchymal CD73, hematopoietic CD34, pluripotent Nanog, and Oct4 markers in bovine fetal BM-MSC and AT-MSC. High proportion of BM-MSC and AT-MSC expressed CD73, Nanog and Oct4. BM-MSC expressed higher levels of CD34 compared to AT-MSC. (a–c) Indicate significant (P < 0.05) difference between cell types and marker expression. BM-MSC: Bone marrow-derived mesenchymal stem cells; AT-MSC: adipose tissue-derived mesenchymal stem cells.
