Blood proteins steroid hormones. Globulins make up 38% of blood proteins and transport ions, hormones, and lipids assisting in immune function. Fibrinogen comprises 7% of blood proteins; conversion of fibrinogen to insoluble fibrin is essential for blood clotting. The remainder of the plasma proteins (1%) are regulatory proteins, such as enzymes, proenzymes, and hormones. All blood proteins are synthesized in liver except for the gamma globulins. Separating serum proteins by electrophoresis is a valuable diagnostic tool as well as a way to monitor clinical progress. Current research regarding blood plasma proteins is centered on performing proteomics analyses of serum/plasma in the search
Angiocrine growth factors Angiocrine growth factors Angiocrine growth factors are molecules found in blood vessels' endothelial cells that can stimulate organ-specific repair activities in damaged or diseased organs. Endothelial cells possess tissue-specific genes that code for unique growth factors, adhesion molecules and factors regulating metabolism. The discovery emerged after the entirety of active genes in endothelial cells was decoded, resulting in an atlas of organ-specific blood vessel cells. The atlas documented hundreds of already-known genes that had never been associated with these cells. Organs dictate the structure and function of their own blood vessels, including the repair molecules they secrete. Each organ produces
