introduction: the purpose of this study was to evaluated the effect of β-mercaptoethanol on resumption of meiosis, in vitro maturation of immature mouse oocytes and resulting embryo development with and without bso (dl-buthionine sulfoximine). material and methods: germinal vasicle (gv) were recovered from 6-8 weeks old nmri ovaries and cultured in maturation medium in memα supplemented with 7....
A technique is described by which a medium composed of fibrinogen suspension, serum, and embryo juice may be made. Fibroblasts grew in this medium about as well as in plasma and embryo juice. A strain of connective tissue in this medium remained practically as active as the control for several passages.
most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. the general use of nmri outbred mice is a model for toxicology, teratology and pharmacology. nmri mouse embryo exhibit the two-cell block in vitro. the objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...
Background: In recent years, a combination of hormones and agents in assisted reproductive technology (ART) cycles as a means of stimulating the ovary and developing more follicles. With respect to the positive effects of Estradiol Valerate on reproductive tissues and the impact on native genes of the egg that transferred to the embryo after fertilization, it seems that this agent can also effe...
Purpose: This Study evaluated the resumption of meiosis, in vitro maturtion and department of immature mouse oocytes with b- mercaptothanol. Materials and methods: Immature oocytes were recovered from NMRI mouse strain (4-6 weeks) in different 4 experiments groups: the control group, the oocytes were matured in MEM-a+ medium containing + FCS 55%; group 1: the oocytes were matured in MEM- a med...
plant regeneration was achieved in verbascum speciosum schard. via organogenesis and somatic embryogenesis by culture of mature embryo explants. two types of calli, embryogenic and non-embryogenic, were induced from mature embryo explants on murashige and skoog (ms) medium supplemented with different concentrations of benzyl adenine (ba) and α-naphthalene acetic acid (naa). in order to further ...
The use of pH-stable media would simplify embryo vitrification and the warming of porcine embryos and might facilitate the application of embryo transfer in practice. In this work, we investigated whether a pH-stable basal medium constituted of Tyrode's lactate medium, polyvinyl alcohol, and HEPES for buffering was suitable for porcine embryo vitrification warming in place of the conventional g...
background: progress achieved in culture media formulations have resulted led to an improvement in maintaining the mammalian embryo in culture throughout the preimplantation and pre-attachment period. objective: the objective of this study was to evaluate the effect of various concentrations of myo-inositol during in vitro fertilization of bovine oocytes on subsequent embryo development. materi...
Study question: Does the type of medium used to culture fresh and frozen-thawed embryos influence neonatal birthweight after single embryo transfer (SET) in IVF? Summary answer: A comparison of two commercially available culture media showed no significant influence on mean birthweight and mean birthweight adjusted for gestational age, gender and parity (z-scores) of singletons born after a fre...
For sexual reproduction of Allium hirtifolium, collected bulbs were planted in the field. In order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. Ovary development and seed setting of A. hirtifolium extraordinary were affected by pollination and there was a significant difference between mean effect of se...
