Fig. 2From: Preclinical study of human umbilical cord mesenchymal stem cell sheets for the recovery of ischemic heart tissueCharacterization of isolated hUC-MSCs. A Morphology of hUC-MSCs in passage 5 attached on the polystyrene culture dishes; A The differentiation capability of hUC-MSCs was confirmed by Oil Red O staining for adipogenesis, Alizarin Red S staining for osteogenesis and Alcian blue staining for chondrogenesis; C Immunophenotypic characteristics obtained from flow cytometric analysis indicate that the isolated hUC-MSCs expressed mesenchymal markers such as CD73, CD90 and CD105 but negative for hematopoietic lineage markers CD11b, CD19, CD34, CD45 and HLA-DRBack to article page
