Nature, 1980
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 ...

AbstractThe light‐microscopic localization of receptors and other molecules by autoradiography of radioligand binding in tissue sections provides a high degree of anatomical resolution and the ability to associate even small quantities of binding sites with anatomical structures. The basic procedure in this unit involves incubating slide‐mounted tissue

In Vitro: Hemic Cells in Vitro.
Archives of Internal Medicine, 1970Inadequacies of the classical science of tissue morphology based on conventional microscopy were evident long before the advent of modern, integrated morphology. These inadequacies resulted mainly from the static nature of classical morphology: a cell or tissue studied by the conventional light microscope is not very informative about its past, its ...

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.

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 ...

AbstractThe two most frequently used systems for in vitro translation are the rabbit reticulocyte system and the wheat germ extract. These systems are useful for mRNAs isolated from cells, tissues, and capped or uncapped mRNA produced in vitro by transcription of cDNA.

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 ...
