The present invention can be expected to have a high therapeutic effect, and at the same time provides a high-tissue biological tissue sheet for transplantation. The biological tissue sheet of the present invention comprises the steps of: (a) preparing a biologically derived cell, (b) inoculating the biologically derived cell on amnion, (c) culturing the biologically derived cell in the absence of heterologous animal cells and Prepare according to the step of propagation. As the biologically derived cells, for example, cells derived from corneal epithelium, conjunctival epithelium, skin epidermis, hair follicle epithelium, oral mucosa, airway mucosa or intestinal mucosa are used. |
