As the immune cells in the recipient recognize transplanted cells as foreign, they mount an inflammatory response that can lead to the body rejecting the transplant.

Eye diseases — such as age - related macular degeneration, as well as a genetic condition called Stargardt's macular dystrophy that afflicts young people — are considered excellent candidates for stem cell therapy because the eye is an immune - privileged site, meaning transplanted cells are not as likely to be rejected as foreign compared with transplants elsewhere.

The research team tested the hypothesis by transplanting cells onto the surface of mouse bone grafts and studying the cell behavior both in vivo — inside the animal — and in vitro — outside the body.

Typically too, there are not enough cells to harvest, and transplanted cells begin to die within a few years.

And iPS cells may have a particular advantage: Taking a person's own skin cells, say, making them pluripotent, and then using those cells to grow whatever kind of tissue is needed could eliminate the use of debilitating immunosuppressive drugs, which are required when transplanting cells or tissue from a donor.

Discussion Points • Do transplanted cells mediate any type of functional recovery?

Through a series of mouse model experiments, the research team determined that a mother's immune response prevents a fetus from accepting transplanted blood stem cells, and yet this response can be overcome simply by transplanting cells harvested from the mother herself.

At least in theory, producing regulatory T cells could promote immune tolerance and prevent the body from rejecting newly transplanted cells.

We suggest correct identification of the origin of these cells (using human specific markers, which define cell membranes) is essential in order to distinguish viable donor cells from host inflammatory cells which have engulfed transplanted cells.
