Studies on Amphibian Yolk
The yolk platelets of mature eggs and young embryonic cells of all amphibian species studied (Rana pipiens, Triturus pyrrhogaster, Diemictylus viridescens, Rana nigromaculata, and Bufo vulgaris) have a superficial layer of fine particles or fibrils (ca. 50 A in diameter), a central main body with a crystalline lattice structure, and an enclosing membrane approximately 70 A in thickness. Electro...
متن کاملChloride currents in acutely isolated Xenopus retinal pigment epithelial cells.
The retinal pigment epithelium (RPE) regulates the ionic composition of the fluid surrounding the photoreceptors by transport mechanisms that utilize Cl- channels. Cl- currents in RPE cells, however, remain incompletely characterized. The purpose of this study was to identify the Cl- currents in acutely isolated Xenopus RPE cells using whole-cell patch clamp. We describe three different Cl- cur...
متن کاملVoltage-dependent Na(+) currents in mammalian retinal cone bipolar cells.
Voltage-dependent Na(+) channels are usually expressed in neurons that use spikes as a means of signal coding. Retinal bipolar cells are commonly thought to be nonspiking neurons, a category of neurons in the CNS that uses graded potential for signal transmission. Here we report for the first time voltage-dependent Na(+) currents in acutely isolated mammalian retinal bipolar cells with whole ce...
متن کاملMembrane currents in retinal bipolar cells of the axolotl
By whole-cell patch-clamping bipolar cells isolated from enzymatically dissociated retinae, we have studied the nonsynaptic ionic currents that may play a role in shaping the bipolar cell light response and in determining the level of voltage noise in these cells. Between -30 and -70 mV, the membrane current of isolated bipolar cells is time independent, and the input resistance is 1-2 G omega....
متن کاملAmphibian resources on the internet.
The use of amphibians in classrooms and research laboratories has increased, along with a corresponding increase in the amount of information about these animals on the Internet. This review is intended to aid both novices and experts in the search of such information. The bibliography of Internet resources is organized by discipline and includes general and selected species information, taxono...
