The upregulation of CREB3L4 in gastic cancer cells increased cell viability, promoted cell proliferation, reduced apoptosis, enhanced cell migration and invasion, and induced the formation of tubule-like endothelial structures, whereas CREB3L4 knockdown impeded tumor cell growth, attenuated cell motility, and prevented human umbilical vein endothelial cells from forming tubule-like structures.

The in vivo results showed that FGF21 efficiently improved blood perfusion and ischaemic angiogenesis in both type 1 and type 2 diabetic mice, and these effects were accompanied by enhanced endothelial progenitor cells mobilization and infiltration into ischaemic muscle tissues and increases in plasma stromal cell–derived factor‐1 concentration.

The authors determined that Tspan18, a member of the Tetraspanin family, was expressed in developing vessels but not in mature vasculature in zebrafish and mouse wound healing. Reduction at Tspan18 level resulted in aberrant vascular patterning, impaired vessel stability and defective arterial–venous specification.
Scientists assembled five groups of chosen endothelial progenitor cells (EPCs)-related genes/factors using PubMed literature and Gene Ontology databases. This shortened database of EPC factors was fed into publically published transcriptome matrix to compare their expression between endothelial colony-forming cells, HUVECs, and two adult endothelial cell types from the skin and adipose tissue.
