Liver stromal cells for prevention and treatment of immune responses in transplantation
First Claim
Patent Images
1. A method of reducing an immune response of effector cells against an alloantigen to the effector cells in a transplant recipient comprising:
- administering to the transplant recipient isolated adult liver stromal cells (LSCs) wherein the LSCs are incapable of differentiating into fat cells or bone producing cells, in an amount effective to reduce an immune response of effector cells against an alloantigen to the effector cells, whereby in the transplant recipient the effector cells have a reduced immune response against the alloantigen.

Abstract
The present invention encompasses methods and compositions for reducing an immune response to a transplant in a recipient by treating said recipient with an amount of liver stromal cells effective to reduce or inhibit host rejection of the transplant. Also disclosed is a method of inducing a reduced immune response against a host by foreign tissue, i.e., graft versus host disease, by treatment with liver stromal cells.

23. A method for reducing an immune response of effector cells against an alloantigen to the effector cells in a transplant recipient comprising:
administering to a recipient a transplant treated with isolated adult liver stromal cells (LSCs) wherein the LSCs are incapable of differentiating into fat cells or bone producing cells in an amount effective to reduce an immune response of effector cells against an alloantigen to the effector cells, whereby in the transplant recipient the effector cells have a reduced immune response against the alloantigen. - View Dependent Claims (24)
