Why are cartilage transplants successful?

Cartilage does not contain blood vessels. Oxygen, nutrients, and cellular wastes diffuse through the selectively permeable matrix. Cartilage transplants are successful because foreign proteins in the transplanted cells do not have a way to enter the host body’s circulation and cause an immune response. However, since there are no blood vessels in cartilage, the healing process is slower than for other tissues.
