Why would it not?? It ought not be a problem to use the prospective host's own cells. We already know how to extract and multiply many different types of body cells. Such multiplication is already done routinely for stem cells.
The "framework" the cells would be printed into would either be a bio-compatible or designed to dissolve after some time frame.
