【题文】 What happens when you cross stem cells from a frog heart and frog skin? Not much-that is, until you program those cells to move. In that case, you've created a xenobot, a new type of organism that's part robot, part living thing. Now a team of scientists has used living...
A vasa-like gene in zebrafish identifies putative primordial germ cells The vasa gene is essential for germline formation in Drosophila. Vasa-related genes have been isolated from several organisms including nematode, frog and ... LC Olsen,R Aasland,A Fjose - 《Mech Dev》 被引量: 558发表: ...
Bipolar cells of the frog retina: A Golgi study The morphology of Golgj-impregnated bipolar cells of the frog ( Rana temporaria) retina has been investigated. Several new kinds of bipolar cells, in addit... EG Shkolnik-Yarros,TA Podugolnikova - 《Vision Research》 被引量: 8发表: 1978年 ...
1. The impulse discharge of ganglion cells was recorded with extracellular micro-electrodes in the excised and opened eye of the common frog, Rana temporaria. 2. When a single unit was isolated, the cell type was first determined according to the Maturana, Lettvin, McCulloch & Pitts (1960)...
The glossopharyngeal nerve of the frog is made up of afferent nerve fibers and efferent, parasympathetic and sympathetic nerve fibers. The precise origin and course of the parasympathetic efferent nerve fibers in the fungiform papillae of the frog's tongue were investigated. We found the ganglion...
Incubation of frog sartorius muscles for 18 hours at constant external concentrations of K+ and Na+, but with the external concentration of Mg++ varying from 1.2 to 73.2 mM, brought about no change in the resting potential which remained constant at 88 mV. Results were the same in MgCl2 as...
Unlike typical mammalian red blood cells, those from amphibians, such as frogs, contain a DNA-bearing nucleus that is visible in the center of the cell. The circulatory system of amphibians is rather unusual, their hearts having three chambers, two atria
Gynogenesis is one of unisexual reproduction modes in vertebrates, and produces all-female individuals with identical genetic background. In sexual reproduction vertebrates, the roles of primordial germ cells on sexual dimorphism and gonadal differentiat
