  • Patent number: 10415014
    Abstract: A method for the ex vivo cultivation of oral mucosal epithelial progenitor cells and oral mucosal epithelial cells includes: subjecting an oral mucosal tissue to an enzymatic digestion treatment with collagenase, so as to obtain cell aggregates which include oral mucosal epithelial progenitor cells and oral mucosal epithelial cells; cultivating the cell aggregates with an amniotic membrane in a serum-free platelet lysate-containing medium in the absence of feeder cells, so that the cell aggregates are adhered onto the amniotic membrane; and subsequently cultivating the cell aggregates adhered on the amniotic membrane in a serum-free proliferation-facilitating medium in the absence of feeder cells.

  • Publication number: 20190099401
    Abstract: A method for protecting corneal endothelial cells from the impact caused by an eye surgery is disclosed. The ophthalmic composition is administered to a patient's eye continuously for at least five days before an eye surgery for reducing the impact to the corneal endothelial cells caused by the eye surgery. The ophthalmic composition comprises an ascorbic acid and a pharmaceutically acceptable ophthalmic carrier.

  • Publication number: 20080233552
    Abstract: The present invention discloses a method of cross-linking amnion to be an improved biomedical material. The present invention adopts the amnion cross-linked by EDC (N-(3-dimethylaminopropyl)-N?-ethyl-carbodiimide HCI) or NHS (N-hydroxysuccinimide), and the cross-linked amnion not only has more resistance to protease, but also binds specific extracellular matrix (ECM) such as heparin by using cross-linked functional group. Further, by using the affinity of the ECM with specific growth factors, the amnion can be an efficient carrier for specific growth factor. Hence, some specific diseases may be treated.
