Colony-Stimulating Factor from Umbilical Cord Endothelial Cells
Description:
Conditioned media prepared from umbilical cord (UC) segments or endothelial cells (EC) contain colony stimulating activity, Both UCCM and ECCM were partially purified by DEAE-Sepharose and ACA44 gel filtration chromatography. The molecular weights were estimated as 25,000 and 31,000 for UC-CSF and EC-CSF, respectively. UC-CSF was further fractionated by Con A Sepharose, IEF and HPLC on a hydrophobic phenyl column. The highly purified CSF stimulates human macrophage and granulocyte colony format…
