PubMed PubMed Product Detail The highly glycosylated 75-120 kD antigen CD34 is possibly an adhesion molecule with a putative role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. It could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. CD34 is thought to have a role in presenting carbohydrate ligands to selectins. The intracellular chain of the CD34 antigen is a site of phosphorylation by activated protein kinase C, suggesting a putative role in signal transduction. Two isoforms of CD34 have been reported to be generated by alternative splicing. CD34 is highly expressed on hematopoietic progenitors, as well as on endothelial cells, brain, and testis. Staining for CD34 has been used to measure angiogenesis, which reportedly predicts tumor recurrence.
Function:
Possible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins.

间充质Stem cells(mesenchymal stem cells,MSC)也是Stem cells家族的重要成员,来源于发育早期的中胚层和外胚层。MSC最初在骨髓中发现,因其具有多向分化潜能、造血支持和促进Stem cells植入、免疫调控和自我复制等特点。如间充质Stem cells在体内或体外特定的诱导条件下,可分化为血管内皮、脂肪、骨、软骨、肌肉、肌腱、韧带、神经、肝、心肌、等多种组织细胞。Product Picture Sample:
