Abstract
A sheet-shaped composition is provided which has an improved preservability and handling readiness, as well as a high flexibility in use. Amnion with trehalose added thereto is utilized. Addition of trehalose improves the flexibility of the amnion, and prevents basal membrane and stratum compactum from being damaged during lyophilization process.
