Allogeneic Umbilical Cord Blood-derived CXCR4-enriched T-regulatory Cells CK0804

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A preparation of allogeneic T-regulatory cells (Tregs) derived from umbilical cord blood (UCB) and enriched with C-X-C chemokine receptor type 4 (CXCR4), with potential immunomodulatory activity. Upon administration, allogeneic UCB-derived CXCR4-enriched Tregs CK0804 may promote immunologic homeostasis and modulate immune responses. CXCR4 enrichment promotes the traffic of the Tregs to the bone marrow and its retainment in the bone marrow, as bone marrow expresses the CXCR4 ligand stromal cell-derived factor 1 (CXCL12).

**Synonyms:** - Allogeneic UCB-derived CXCR4-enriched Tregs CK0804 - CK 0804 - CK-0804 - CK0804
