Bovine brain and purification of two different growth factors and characteristics
Analysis indicates that purified from bovine brain HGF-z and purified from bovine hypothalamus of the HGF-z is the same that most of their amino acids and has proved the composition and molecular weight and from bovine brain were isolated by multi-step chromatography of acidic Fibroblast growth factor (aFGF) the same as In; HGF is clearly different from H0F_. Isolated with the pituitary basic fibroblast growth factor (bFGF) is basically the same These results suggest that the nervous tissue of cattle is an acid anion H mitogen ,[link widoczny dla zalogowanych], while HGF a cation is an alkaline promoting cell Splitting agent. HGF is considered to be a class of broad-spectrum growth factor,[link widoczny dla zalogowanych], has a broad target cell specificity, on fibroblasts and vascular endothelial cells and other types of cells from different cells with the stimulating effect of HGF ,[link widoczny dla zalogowanych], but the sensitivity is different Such as HGF stimulated the I3 fibroblasts and umbilical vein endothelial cells , while HGF a major bovine aortic endothelial cells that stimulate growth ,[link widoczny dla zalogowanych], these observations suggest that , HGF in the target cells is a difference between the specificity of the test The results show that bovine brain with mitogen activity of growth factors may be only two: one is anion mitogen , another is a cationic agent to promote cell division , were named as a growth factor and heparin statement sets ~ ( HGF and heparin binding growth factor a for a / ~ (HGF one we used heparin affinity chromatography purified from bovine brain performance of a homogeneous two growth factors for the further study of the structure and clinical application of biological functions have provided favorable conditions Key words heparin affinity chromatography : bovine brain : heparin-binding growth factors : fibroblast growth factor
