Capacitation is a prerequisite for mammalian spermatozoa to fertilize oocytes. Lipids play a crucial role in the structural and functional organization of sperm plasma membrane. Lipid and membrane protein ordering changes dramatically during sperm capacitation but the resulting effects differ according to the regions of the sperm head.

Abstract Starvation for 48 h and diabetes (induced either by alloxan treatment or by pancreatectomy) resulted in increasing degrees of ketosis in rats. Optimal conditions were established for acetoacetate synthesis from CoASAc in homogenates of liver taken from animals of all experimental groups.

In vitro fertilization (IVF) is a technical process in which retrieved oocytes are fertilized outside the body. The developing embryos grow in a laboratory environment and are subsequently transferred into the woman's uterus. The IVF technique was first introduced as a treatment for infertility in 1978 and success rates have steadily increased in the ...

In vitro maturation (IVM) is an in vitro fertilisation (IVF) technique modified to collect immature oocytes from antral follicles, with the final stages of meiosis completed during in vitro culture. The primary benefit of IVM is that it reduces gonadotrophin stimulation in the patient, thereby eliminating the risk of ovarian hyperstimulation syndrome ...

AbstractIn vitro analysis of transcription and the factors that play a role in transcription require preparation of an extract that faithfully reproduces in vivo transcription. This unit describes protocols for generating extracts of mammalian cells and Drosophila embryos that are competent for in vitro transcription reactions using naked DNA or ...

This comprehensively updated and expanded second edition builds on its successful and popular predecessor, retaining the practical features which made the first edition such an essential guide to IVF. The edition describes additions to the range of ART clinical treatments, including the use of testicular and epididymal sperm, blastocyst stage transfer,

The processes by which diversity is acquired and maintained during embryogenesis have been repeatedly described but are as yet not understood. One fascinating example of diversity following gastrulation is epidermal organogenesis and in particular embryonic tooth morphogenesis.

Studies in vitro of oncogenic agents have attained an ever increasing importance mainly because of the precision and ease by which events at the cellular and sub-cellular level can be followed. This article will examine the relevance of such data for the understanding of a much more complicated process — the development of spontaneous malignant tumors ...

IN 1935, Gautheret1 published an account of in vitro grafts he had obtained between fragments of cambium of Populus nigra, Salix caprea and other trees, excised and cultured on artificial media. In attempting to repeat this work, I encountered some difficulties when tissues freshly removed from the plant were employed.
