Comparison of the effect of two different handling media on rabbit zygote developmental ability.
Despite the attention paid to culture media, the relevance of the handling medium at egg recovery/transfer is frequently overlooked. In the present work, we compare the effect of two different handling media (PBS and HEPES-buffered Ham F10, both supplemented with 20% (v/v) FCS), upon in vitro and in vivo developmental ability of in vivo fertilised rabbit zygotes. Zygotes recovered in HEPES-buff...
متن کاملZygote Intrafallopian Transfer
Zygote intrafallopian transfer (ZIFT) is an assisted reproductive technology [5] (ART) first used in 1986 to help those who are infertile conceive a child. ZIFT is a hybrid technique derived from a combination of in vitro [6] fertilization [7] (IVF) and gamete intrafallopian transfer (GIFT) procedures. Despite a relatively high success rate close to that of IVF, it is not as common as its paren...

متن کاملCOTTON EMBRYOGENESIS Polysome Forlmation in the Zygote
The formation of the zygote in cotton is accompanied by marked changes in the number and aggregation of the ribosomes. The zygote is formed approximately 14 hr after pollination but does not divide for some 56-60 hr. Electron microscope studies of the zygote during this period reveal a series of changes in the size and distribution of polysomes which may provide information on this important st...
متن کاملCould a zygote be a human being?
This paper re-examines the question of whether quirks of early human foetal development tell against the view (conceptionism) that we are human beings at conception. A zygote is capable of splitting to give rise to identical twins. Since the zygote cannot be identical with either human being it will become, it cannot already be a human being. Parallel concerns can be raised about chimeras in wh...
