Purification of fetal hematopoietic progenitors and demonstration of recombinant multipotential colony-stimulating activity.
To facilitate the direct study of progenitor cell biology, we have developed a simple and efficient procedure based upon negative selection by panning to purify large numbers of committed erythroid and myeloid progenitors from human fetal liver. The nonadherent, panned cells constitute a highly enriched population of progenitor cells, containing 30.4 +/- 13.1% erythrocyte burst forming units (B...
متن کاملIsolation and Partial Purification of Hepatic Stimulatory Substance.
THE PURPOSE of this study was to purify and characterize hepatic stimulatory substance (HSS), a protein found in the liver that has been reported to stimulate hepatic DNA synthesis and hepatocyte replication and that was previously identified by LaBrecque et al l -3 and Francavilla et al in the rat liver,4,5 as well as by Starzl et al in the canine liver.6,7 HSS has been partially purified by s...
متن کاملPurification and properties of human hepatic aspartylglucosaminidase.
Aspartylglucosaminidase (EC 3.5.1.26), the lysosomal enzyme which hydrolyzes the N-acetylglucosamine-asparagine linkages in glycoproteins, was purified from human liver to homogeneity. The purification procedure included chromatography on DEAE-cellulose and concanavalin A-Sepharose, gel filtration on Sephadex G-200, and high performance liquid chromatography. The purified enzyme had a final spe...

P-124: Comparative Study of The Effect of Fetal Bovine Serum Concentrations on Expressing of Human Follicle Stimulating Hormone.
Background Follicle stimulating hormone (FSH) produced in recombinant Chinese hamster ovary (CHO) cells used for infertility treatment. Fetal Bovine Serum (FBS) in known as a factor in medium culture that provides the tolerance towards physiochemical variations and protects cells against apoptosis; on the other hand, FBS is the most expensive component in medium culture and collection that caus...
