Erythropoietin administration to improve graft survival
First Claim
1. A method of treating Parkinsonism comprising:
- (a) contacting a tissue graft comprising differentiated dopamine producing neurons with an effective amount of exogenous erythropoietin (EPO) or an isoform or peptide analog of EPO or administering the EPO, an isoform or peptide analog of EPO or combinations thereof to the tissue graft; and
(b) administering the tissue graft into a compatible recipient neuronal tissue in a subject suffering from Parkinsonism, wherein the survival of cells in the tissue graft is increased, compared to cells in a tissue graft not contacted with EPO or an isoform or peptide analog thereof,wherein step (a) occurs prior to step (b).

Abstract
The present invention provides methods, compounds and kits for increasing the viability of cells. The methods involve treating cells that make up a tissue graft with erythropoietin before, during or after delivery or administration. The method can employ cells of different types, including cells of neural or paraneural origin, such as adrenal chromaffin cells. Also useful are cell lines grown in vitro. Cells not of neural or paraneural origin, such as fibroblasts, may also be used following genetic alteration to express a desired neural product such as a neurotransmitter or a neuronal growth factor. The method is used to treat neurological diseases such as Parkinson'"'"'s disease, Alzheimer'"'"'s disease, Huntington'"'"'s disease, epilepsy, and traumatic brain or spinal cord injury.
