Ovaries of a transgenic FVB/N-Tg (PolII–Luc) Ltc mouse were transplanted under the back muscle (arrow) of FVB/N wild-type recipient mouse (left). In vivo BLI of mouse ovarian grafts in fresh and frozen–thawed ovary transplant groups on days 1, 3, 5, 7 and 10 after transplantation (upper right). In the fresh ovaries, bioluminescence increased initially on day 3, then decreased between days 3 and 7 and rose again from day 7 to day 10 with a subsequent cyclic fluctuation in intensity. In the frozen–thawed ovaries, the bioluminescence was no different after transplantation (lower right).
