Cloned capillary endothelial cells, cultured in tumour-conditioned medium, form capillary tubes. By light and electron microscopy these tubes resemble capillaries in vivo. This first demonstration of angiogenesis in vitro: (1) shows that all the information necessary to develop an entire capillary network in vitro is expressed by one cell type; (2 ...

Specific enzymatic amplification of DNA in vitro: the polymerase chain reaction.
Cold Spring Harbor Symposia on Quantitative Biology, 1986The discovery of specific restriction endonucleases (Smith and Wilcox 1970) made possible the isolation of discrete molecular fragments of naturally occurring DNA for the first time.

Pharmaceutisch Weekblad Scientific Edition, 1986
The first quinolone compound, nalidixic acid, showed activity against a limited number of Gram-negative micro-organisms. 'One step' resistance developed in vitro and during treatment. Resistance was not mediated by transfer of R-plasmids, which is a characteristic of all quinolones.

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 ...

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.

Developmental Biology Pluripotent embryonic stem cells (ESCs) can differentiate into any adult cell type; however, aggregates of these cells do not mimic embryonic architecture when grown in culture. To see whether mouse ESCs and their extraembryonic counterparts, trophoblast stem cells (TSCs), can recapitulate normal development, Harrison et al ...

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 ...

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 ...
