Abstract
The corneal epithelium (CE), the most anterior cellular structure of the eye, is a self-renewing stratified squamous tissue that protects the rest of the eye from external elements. Each cell in this exquisite three-dimensional structure needs to have proper polarity and positional awareness for the CE to serve as a transparent, refractive, and protective tissue. Recent studies have begun to elucidate the molecular and cellular events involved in the embryonic development, post-natal maturation, and homeostasis of the CE, and how they are regulated by a well-coordinated network of transcription factors. This review summarizes the status of related knowledge and aims to provide insight into the pathophysiology of disorders caused by disruption of CE development, and/or homeostasis.
期刊介绍：
Differentiation is a multidisciplinary journal dealing with topics relating to cell differentiation, development, cellular structure and function, and cancer. Differentiation of eukaryotes at the molecular level and the use of transgenic and targeted mutagenesis approaches to problems of differentiation are of particular interest to the journal.
The journal will publish full-length articles containing original work in any of these areas. We will also publish reviews and commentaries on topics of current interest.
The principal subject areas the journal covers are: • embryonic patterning and organogenesis
• human development and congenital malformation
• mechanisms of cell lineage commitment
• tissue homeostasis and oncogenic transformation
• establishment of cellular polarity
• stem cell differentiation
• cell reprogramming mechanisms
• stability of the differentiated state
• cell and tissue interactions in vivo and in vitro
• signal transduction pathways in development and differentiation
• carcinogenesis and cancer
• mechanisms involved in cell growth and division especially relating to cancer
• differentiation in regeneration and ageing
• therapeutic applications of differentiation processes.
