Changes in hair growth characteristics following the wounding of vibrissa follicles in the hooded rat.
The effect on hair growth of wounding the lower region of whisker follicles, and in particular the dermal papilla, with sharply pointed tungsten needles was studied in adult hooded rats. Following injury hair growth ceased, but was subsequently resumed. While it might have been anticipated that follicle wounding would have a negative effect on whisker length, regular postoperative length measur...
متن کاملInduction of hair follicles in mouse skin by rat vibrissa dermal papillae.
Rat vibrissa dermal papillae were transplanted between the epidermis and dermis of isolated embryonic mouse skin and then grafted onto nude mice. The papillae induced the formation of hair follicles which were larger than those of the host skin but smaller than vibrissa follicles. The potential of isolated dermal papillae to induce follicles with characteristics of those from which the papillae...
متن کاملHistological studies of the effects of wounding vibrissa follicles in the hooded rat.
The effects of wounding the lower region of rat vibrissa follicles with a sharp tungsten needle were examined histologically, both shortly after injury and up to one year postoperatively. Following cell damage in the dermal papilla component hair growth ceased, and resumption of fibre production was always preceded by dermal papilla reformation. This papilla healing and regeneration was not ass...
متن کاملStructural changes in the developing retina maintained in vitro
The present study examined the emergence of structural remodeling in explanted neonatal rat retina. Immunohistochemical analysis demonstrated signs of glial and neuronal remodeling after 11 days in vitro and included the activation of Müller cells, the formation of ectopic neuropil areas and sprouting of photoreceptor terminals. We also observed that cholinergic and GABA-ergic amacrine cells di...
