Abstract
The dried amniotic membrane is produced by drying a fresh amniotic membrane, which envelopes an embryo of an animal including human, and can be used as a substitute membrane for a membrane tissue in a living body; the dried amniotic membrane is dehydrated and dried so that the dried amniotic membrane can be stored in a dry air in a sterile state; when hydrated again by immersing in water or a buffer solution, the amniotic membrane still has an epithelial cell, a basement membrane and a connective tissue which constitute the fresh amniotic membrane. The dried amniotic membrane is useful as a medical substitute membrane for a membrane tissue in a living body such as a dura mater, a meninx, a pericardium, a pleura and a peritoneum.
