Mammalian multipotent stem cells and compositions, methods of preparation and methods of administration thereof
View Patent ↗This invention provides methods for preparing novel mammalian multipotent stem cells (MSCs), compositions thereof, and methods of preparing and administering the cells.
1. A method for improving cognitive function in a human patient, the method comprising the step of: (a) administering a pharmaceutically effective amount of more developmentally potent cells to the patient; wherein the more developmentally potent cells are obtained by contacting neural stem cells or mesenchymal stem cells with an effective amount of substituted deoxynucleotide or deoxynucleoside for an effective period, wherein the substituted deoxynucleotide or deoxynucleoside compound-contacted neural stem cells or mesenchymal stem cells become more developmentally potent, and wherein said more developmentally potent cells are capable of migrating to an area of neurological deficit, differentiating in a tissue-specific manner and functioning in a manner that improves cognitive function.
2. The method of claim 1 wherein the cells are administered by injecting the more developmentally potent cells with a syringe, inserting the more developmentally potent cells with a catheter or surgically implanting the more developmentally potent cells.
3. The method of claim 1 , wherein the more developmentally potent cells comprise a cluster of two or more cells.
4. The method of claim 1 , wherein the more developmentally potent cells are injected with a syringe into a body cavity that is fluidly-connected to the area of neurological deficit.
5. The method of claim 1 , wherein the more developmentally potent cells are inserted with a catheter into a body cavity that is fluidly-connected to the area of neurological deficit.
6. The method of claim 1 , wherein the more developmentally potent cells are surgically implanted into a body cavity that is fluidly-connected to the area of neurological deficit.
7. The method of claim 1 , wherein the more developmentally potent cells are injected with a syringe to the area of neurological deficit.
8. The method of claim 1 , wherein the more developmentally potent cells are injected with a catheter to the area of neurological deficit.
9. The method of claim 1 , wherein the more developmentally potent cells are surgically implanted to the area of neurological deficit.
10. The method of claim 1 , wherein the more developmentally potent cells are administered systemically.
11. A method for treating a disorder affecting vision caused by a loss or failure of retinal cells in a retina of a patient, the method comprising the step of: (a) administering to the patient a pharmaceutically effective amount of more developmentally potent cells to the patient; wherein the more developmentally potent cells are obtained by contacting mesenchymal stem cells with an effective amount of substituted deoxynucleotide or deoxynucleoside for an effective period, wherein the substituted deoxynucleotide or deoxynucleoside compound-contacted mesenchymal stem cells become more developmentally potent, and wherein said more developmentally potent cells are capable of migrating to the retina, differentiating in a tissue-specific manner and functioning as retinal cells.
12. The method of claim 11 , wherein said more developmentally potent cells are administered via a vitreous cavity.
