Mouse cluster Of differentiation 34,CD34 ELI

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 (By similarity).
