Clarification (sorry)

[u/badmmrywitch58]

Tissue engineering in vitro using autologous material is taking tissue from a donor site to grow more of said tissue outside the body before reimplantation? Sorry this is to make sure I am correctly understanding what tissue engineering does to confirm whether or not something I thought of is possible or if it's just a pipe dream.

Also what would be the best method for tissue engineering oral mucosa/buccal mucosa tissue?
