Fetal calf serum contains activities that induce fetal hemoglobin in adult erythroid cell cultures.
Cultures of peripheral blood or bone marrow erythroid progenitors display stimulated production of fetal hemoglobin. We investigated whether this stimulation is due to factors contained in the sera of the culture medium. Comparisons of gamma/gamma + beta biosynthetic ratios in erythroid colonies grown in fetal calf serum (FCS) or in charcoal treated FCS (C-FCS) showed that FCS-grown cells had s...
متن کاملFetal calf serum increased the zona pellucida penetrability of rat oocytes matured in vitro.
We examined the effect of fetal calf serum (FCS) on meiotic division, subsequent fertilization, and first cleavage to the 2-cell stage of rat oocytes during in vitro maturation. FCS had no effect on the nuclear progression from dictiate to metaphase of the second maturation in vitro and, FCS had no effect on the first cleavage to the 2-cell stage of fertilized oocytes. However, FCS efficiently ...
متن کاملUse of chicken serum as a good replacement for the fetal calf serum in cultivation of promastigotes of Leishmania major
Genus Leishmania is a protozoan parasite that causes different severe diseases. Fetal Calf Serum (FCS) is the major part of the Leishmania culture media, for mass cultivation and the most expensive ingredient in these media. In the present work, the efficacy of chicken serum was evaluated in Leishmania culture media. The results indicated that, the (10%) chicken serum enriched culture medium su...
متن کاملAlbumin and transferrin synthesis in whole rat embryo cultures.
The uptake of [3H]leucine by the rat yolk sac and embryo and the subsequent synthesis of albumin and transferrin have been studied in whole embryo culture. Rat embryos of 12 days gestation were used in all experiments. Isotopically labelled transferrin was detectable in yolk-sac and embryo tissue extracts. In contrast, [3H]albumin could not be found in either tissue extract. Levels of radioacti...
متن کاملReplacement of fetal calf serum by human serum as supplementation for human fibroblast culture
Introduction: Fetal calf serum (FCS) is commonly used as a supplement in the culture medium for fibroblast cells. This supplementation is far from ideal as sample quality varies from batch to batch and the composition of FCS is not completely known. In addition, FCS may be contaminated with viruses and/or prions and may also cause adverse immunologic responses in humans. Due to these facts, a w...
