Does this bypass organ rejection or might this still require continual immunosuppressants? The only clue to this is the following: > Since cells are required to regenerate and maintain this living implant, the team will create two versions of NOVAJoint: a version that uses patient’s own cells and one that uses donor cells. Presuming that the donor cells do require immunosuppressants, this leaves the question of "will the version that does not require donor cells require immunosuppressants, and if so for how long?"
