Further described is a method for isolating stem/progenitor cells from the amniotic membrane of umbilical cord, wherein the method comprises separating the amniotic membrane from the other components of the umbilical cord in vitro, culturing the amniotic membrane tissue under conditions allowing cell proliferation, and isolating the stem/progenitor cells from the tissue cultures. The invention also refers to therapeutic uses of these skin equivalents.Type: ApplicationFiled: October 11, 2006Publication date: October 9, 2008Applicant: CELLRESEARCH CORPORATION PTE LTDInventor: Toan-Thang Phan

Patent number: 7429483Abstract: The nerve growth factor (NGF) is used for the storage of corneas in culture, for the production and the storage in vitro of single cell populations of the corneal morphological and functional unit (i.e. epithelium, stroma/keratocytes and endothelium) and of the conjunctival epithelium, and for the production and the storage of corneal and conjunctival tissues, in particular for transplantation purposes. The NGF is also proposed for use in the therapy and/or the prophylaxis of diseases of the corneal surface, wherein a lack of integrity of the corneal and conjunctival morphological and functional unit occurs, in particular for pathologies having a dystrophic or neurodystrophic basis, both congenital and acquired.Type: GrantFiled: January 8, 2003Date of Patent: September 30, 2008Assignee: Anabasis S.R.L.Inventor: Alessandro Lambiase
