Fetal bovine serum serum and animal derived products through proper origin traceability, truth in labeling and appropriate standardization and oversight.” Fetal bovine serum Fetal bovine serum (FBS) comes from the blood drawn from a bovine fetus via a closed system of collection at the slaughterhouse. Fetal bovine serum is the most widely used serum-supplement for the in vitro cell culture of eukaryotic cells. This is due to it having a very low level of antibodies and containing more growth factors, allowing for versatility in many different cell culture applications. The globular protein, bovine serum albumin (BSA), is a major component of fetal bovine
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
