Abstract

Systems and methods for modifying the environment of target cell using genetically altered chondrocytes are provided. The genetically engineered chondrocytes can be used to express a therapeutic agent in a subject, including in an environment typically associated with chondrocytes and in an environment not typically associated with chondrocytes.

Claims (15)

1. A method for modifying an environment of a target cell associated with a disorder using a genetically altered chondrocyte, comprising:

fully enclosing a genetically altered chondrocyte altered to express a therapeutic agent within one or more discrete semi-permeable containers, each having at least one chamber, the containers configured to retain the genetically altered chondrocyte while allowing passage of the therapeutic agent; and

delivering the one or more containers to the environment of a target cell associated with a disorder;

wherein the therapeutic agent is expressed and released from the one or more containers.

2. The method of claim 1 , wherein the target cell associated with the disorder is in an atypical chondrocyte environment.

3. The method of claim 2 , wherein the atypical chondrocyte environment is in an organ selected from the group consisting of the brain, heart, liver, kidney, gastro-intestinal tract, spleen, smooth muscles, skeletal muscles, eye, ganglions, lungs, gonads, and pancreas.

4. The therapeutic system of claim 2 , wherein the atypical chondrocyte environment is an aqueous environment selected from the group consisting of blood and plasma.

5. The method of claim 1 , wherein the target cell associated with the disorder is in a typical chondrocyte environment.

6. The method of claim 5 , wherein the typical chondrocyte environment is selected from the group consisting of bone, tendon and cartilage.

7. The method of claim 1 , wherein the target cell associated with the disorder is a cell selected from the group consisting of a cell associated with a blood disorder, a cell associated with a cardiovascular disorder, a cell associated with an endocrine disorder, a cell associated with an autoimmune disorder, a cell associated with a neurological disorder, a cell associated with a skin disorder, a cell associated with fertility disorder, and a cell associated with reproduction.

8. The method of claim 1 , wherein the one or more containers comprise a rigid material.

9. The method of claim 1 , wherein the one or more containers further include at least one port.

10. The method of claim 1 , wherein the genetically altered chondrocyte, is genetically altered to produce a therapeutic agent selected from the group consisting of a protein, an agonist or an antagonist of an antibody, an antigen, a hormone, an anti-inflammatory agent, an antiviral agent, an anti-bacterial agent, a growth factor, a cytokine, an oncogene, a tumor suppressor, a transmembrane receptor, an adhesion molecule, a neurotransmitter, a morphogenetic protein, a differentiation factor, an enzyme, and an extracellular matrix protein.

11. The method of claim 1 , wherein the therapeutic agent is an Erythropoietin protein.

12. The method of claim 1 , wherein the therapeutic agent is an Erythropoietin mimetibody.
