ICA had no influence on the characteristics of postthawed NPMSCs cryopreserved with DMSO and ICA. (a) The MSC-associated surface markers (CD105, CD73, CD90, CD34, and HLA-DR) were analyzed by flow cytometry. (b) Histological appearances with Alizarin Red staining (bar = 100 μm). (c) Histological appearances with Oil Red O staining (bar = 100 μm). (d) Histological appearances with Toluidine Blue staining (bar = 50 μm).
