It is intended to provide a biological tissue sheet which is expected as exerting a favorable therapeutic effect and a high safety in transplantation. Namely, a biological tissue sheet is formed by: (a) preparing cells with a biological origin; (b) sowing the cells with a biological origin on amnion; (c) and culturing and proliferating the cells with a biological origin in the absence of any heterogeneous animal cells. As the cells with a biological origin, use can be made of, for example, cells originating in corneal epithelium, conjunctive epithelium, epidermis, follicular epithelium, oral mucosa, airway mucosa or intestinal tract mucosa. ® KIPO & WIPO 2007
