  • Patent number: 10017735
    Abstract: The invention relates to a dual-media approach for culturing isolated corneal endothelial cells. Isolated corneal endothelial cells are first contacted with a proliferative medium to propagate and/or expand the endothelial cells followed by a maintenance medium to preserve the morphology and/or characteristics of the corneal endothelial cells. The invention includes the proliferative medium and the maintenance medium and also a combination of the two medium.

  • Publication number: 20160230142
    Abstract: The present invention relates to corneal stromal keratocytes (CSKs) culture. In particular the present invention relates to a method for culturing corneal stromal keratocytes ex vivo. The method utilises a dual culture medium protocol. In the presence of serum (in particular low serum concentration) in a first culture medium A, the “activated keratocytes” are expandable while specific CSK gene expression is maintained in serum-free ERI condition in a second culture medium B. The invention also relates to culture medium A and B which is supplemented with liquid amnion extract or other additional supplements. This protocol also applied to CSK from other species. Additionally, the present invention provides method for CSK cultivation to provide sufficient quantity of genuine CSKs for corneal tissue engineering without a risk of fibroblastic changes.
