Collapse of growth cone structure on contact with specific neurites in culture.
We have studied the morphology of embryonic chick retinal and sympathetic growth cones as they meet retinal and sympathetic neurites grown in culture. Growth cones preserve their normal morphology and ability to locomote when retinal growth cones contact retinal neurites or when sympathetic growth cones contact sympathetic neurites. Growth cones collapse and their motility ceases when retinal g...
متن کاملThe selective inhibition of growth cone extension by specific neurites in culture.
We have found that neurites from embryonic chick retinal and sympathetic explants do not mix in culture, while retinal neurites mix with retinal neurites, and sympathetic neurites mix with sympathetic neurites. These results confirm those obtained with embryonic rat tissues by Bray et al. (1980). We have also used video time-lapse techniques to examine the behavior of individual retinal and sym...
متن کاملIntracellular calcium levels do not change during contact-mediated collapse of chick DRG growth cone structure.
When the growth cone of a chick dorsal root ganglion (DRG) neurite contacts the neurite of a chick retinal ganglion cell in vitro, the growth cone typically responds by withdrawing its lamellipodia and filopodia and collapsing. We have used the fluorescent calcium indicator dye fura-2 and digital imaging microscopy to measure calcium levels within DRG growth cones and to determine whether chang...
متن کاملXenopus temporal retinal neurites collapse on contact with glial cells from caudal tectum in vitro.
Nasal and temporal retinal neurites were confronted in culture with glial cells from the rostral and caudal parts of the optic tectum and with glial cells from the diencephalon. Twenty of each of the six classes of encounter between individual growth cones and isolated glial cells were analysed by time-lapse videorecording. The results show that growth cones from the temporal retina collapse wh...
