Description

Iba and colleagues define a conserved population of vessel-lining stem cells marked by the protein CD157, in 2026 vascular biology research. Endothelial cells carrying CD157 help renew and maintain blood vessels, but their identity was vague. Comparing gene profiles from mouse and human tissues, the team found these cells share a transcriptional signature enriched for growth genes. The signature is organized by a regulatory network in which the NFAT signaling pathway helps build vessel networks.

Matching human cell clusters sat in the lining of vessels and expressed markers alongside CD157. CD157-positive cells from muscle proliferated more vigorously than their negative counterparts in culture, evidence of stem character. Analysis suggested these cells communicate with neighbors through the CXCL12-CXCR7 signaling axis, a known vessel guidance pathway. Iba proposes the shared signature as a handle for harnessing the vessel's repair crew in regenerative medicine.
