Histological sections of the cell-loaded (left series) and cell-free transplants (right series) on the liver. After 20 days, cells could be observed in the seminiferous tubules (*) of both cell-loaded (a) and cell-free (b) scaffolds. Some cells within the tubules had nuclei with close similarity to sertoli cells (Arrow). The cells surrounding the tubules had elongated nuclei similar to the myoid cells in the tunica propria. After 40 days (c, d), the sertoli-like cells had yet presented within the tubules. Between the tubules, some round eosinophil cells with round centrally located nuclei (arrow) could be also observed (c). At day 60 (e, f), some tubules occupied by fibrous tissue were present within the scaffolds (*)
