Abstract: The present invention relates to an agent for increasing PAX6 gene and/or protein expression in a subject in need thereof. The insertion of a nonsense mutation found in patients allowed inventors to identify altered gene expression of PAX6 target genes, enhanced cell adhesion and reduced cell migration and proliferation. Remarkably, these parameters were rescued by recombinant PAX6 protein. Using this unique cellular model in which they inserted multiple copies of PAX6 responsive elements and tdTomato, they screened a FDA-approved library and identified in a first hit, 3 small compounds that enhance production of PAX6 protein while two of them did not modulate PAX6 gene expression. More particularly, they observed that the small compounds efficiently rescue in vitro migration of mutated limbal cells. Moreover, in the art, it is known that a decrease of PAX6 leads to an induction of diabetes.

Abstract: The present invention relates to a method for promoting wound healing in a subject suffering from Ectodermal dysplasia in need thereof comprising a step of administering subcutaneously, intradermally or topically to said subject a therapeutically effective amount of a compound which restores the activity of p63. Inventors have performed a primary culture of patient keratinocytes suffering from ectodermal dysplasias with two compounds which restore the activity of p63 (e.g. STIMA-1 and/or PRIMA-1Met). They have shown that there is an important differentiation of the keratinocytes of said patient compared to the cells not treated with these compounds. They observed that the activity of p63 mutated is restored, thus the proliferation and differentiation of keratinocytes from the patient are activated. Moreover, inventors have used PRIMA-1Met by topical application on a young patient suffering from ectodermal dysplasias and shown that said patient presents an improvement on her hand.

Abstract: A method of generating a population of corneal epithelial cells is disclosed. The method comprises culturing human pluripotent stem cells in corneal fibroblast-conditioned medium on a solid surface comprising an extracellular matrix component thereby generating the population of corneal epithelial cells. Isolated cell populations and corneal tissues are also disclosed, as well as uses thereof.

Abstract: The present invention relates to a method for inducing the differentiation of mammals' embryonic stem cells into keratinocytes, comprising the following steps of: isolating an extracellular matrix secreted by at least one mammals' cell type, cultivating mammals' embryonic stem cells in parallel in an undifferentiated condition in an appropriate culture medium in the presence of LIF, seeding the embryonic stem cells as a monolayer on said extracellular matrix, cultivating the thus seeded embryonic stem cells in the absence of LIF for a period of time sufficient for their differentiation into keratinocytes, and collecting the thus obtained keratinocytes.
