Abstract
This invention relates to implantation of encapsulated PC12 cells capable of slowing or preventing the degenerative processes of Parkinson's disease by releasing factors in addition to dopamine into individuals suffering from the disease. This restorative effect continues even after the encapsulated cells are removed from the patient's brain.
Claims3
A method for slowing or preventing the progression of Parkinson's disease by implantation of a biocompatible immunoisolatory capsule suitable for implantation into individuals with Parkinson's disease for at least six months, said capsule comprising:
- (a) a core which contains living PC12 cells capable of secreting a biologically active product or of providing a biological function to an individual;
- and
- (b) an external diffusional surface jacket surrounding said core which is biocompatible and which is sufficient to permit passage of substances between the individual and the core and to protect the isolated PC12 cells in the core from immunological attack.
