The first experiments with neural transplantation into the brain
(for a review, see Bjorklund and Stenevi 1985) were reported at the
end of the last century by Thompson (1890), who took cortical
tissue from adult cats and implanted the tissue pieces into the
neocortex of adult dogs. The neurons did not survive, but the
transplanted mass did not disintegrate entirely. Successful graft
ing into the brain was reported later by Ranson (1909), who
implanted spinal ganglia into the cerebral cortex of developing
rats, and by Dunn (1917), who reported survival of implanted
neonatal cortex into the cortex of newborn recipients. Another
important step was made by Le Gros Clark (1940) who reported that,
in the rabbit, embryonic (E) cortical tissue could be successfully
grafted into the cortex of young recipients. Ex periments by
Wallace and Das (1982), and Bjorklund and Stenevi (1984), showing
behavioral effects of grafts, subsequently stimu lated a growing
interest in neurotransplantation research. Intrac erebral grafting
is now considered a powerful tool for addressing fundamental
questions about development, regenerative, or re storative
phenomena in the central nervous system (CNS) and is a potential
therapy for neurodegenerative diseases.
Sa ferocite engendre le mal et anime son vieux corps disgracieux
d'une pulsion sanguinaire. Les griffes en sont ses armes, la
decrepitude en est son poison. N'avez-vous jamais ose lacerer, ce
corps saint qui, sous l'assaut de vos etroites griffes se fletrit
jusqu'a son extreme atonie. N'avez-vous jamais ose apposer votre
griffe sur ce papyrus ardent, vendant votre ame decadente a ce
pervers demon au mepris d'une gloire sans raison.
