Do transplanted organs also replace themselves every 7 years?

Edit: I am curious specifically about kidneys if there are different answers to different organs. Also, kidneys have been known to work in the recipients body for over 20 years so don't tell me it isn't there long enough to replace itself.

Worth noting that the cells that replace those transplanted tissues are coming from stem cell reservoirs within those tissues, so they're still going to be "transplanted." It's not as if the tissue identity is going to slowly revert to the genotype of the transplant patient.
