Microtitration plates were used to culture simultaneously multiple, small (6 mm diameter) explants of bovine retinal pigment epithelium (RPE). Evaluation of tissue by light microscopy and by scanning and transmission electron microscopy after various incubation periods up to 6 h showed that RPE maintained in this system retains near normal morphology.(More)
& Smith, 1968). In the two last-named organs it has been assumed to play an inhibitory neurotransmitter role (Mandel et al., 1976), or a modulatory role of membrane excitability by interfering with ionic, especially calcium, fluxes (Pasantes-Morales et al., 1979). As the distribution of taurine in organs results from external uptake and internal(More)
When bovine neural retinas are incubated in Krebs-Henseleit buffer with D-[3H]-galactose, autoradiography reveals that there is a rapid uptake of the tritium label into the inner segments of cones, but not of rods. Pulse--chase studies show that the label is first associated with the Golgi apparatus in the cones, then appears to travel around the nucleus(More)
