Cell Dev.

Around the developing eye, this multipotent ocular NC cell population, called the periocular mesenchyme (POM), comprises migratory mesenchymal cells that eventually give rise to many of the elements in the anterior of the eye, such as the cornea, sclera, trabecular meshwork, and iris. Molecular cell biology and genetic analyses of congenital eye diseases have provided important information on the regulation of NC contributions to this area of the eye. Nevertheless, a complete understanding of the NC as a contributor to ocular development remains elusive. In addition, positional information during ocular NC migration and the molecular pathways that regulate end tissue differentiation have yet to be fully elucidated. Further, the clinical challenges of ocular diseases, such as Axenfeld-Rieger syndrome (ARS), Peters anomaly (PA) and primary congenital glaucoma (PCG), strongly suggest the need for better treatments. While several aspects of NC evolution have recently been reviewed, this discussion will consolidate the most recent current knowledge on the specification, migration, and contributions of the NC to ocular development, highlighting the anterior segment and the knowledge obtained from the clinical manifestations of its associated diseases. Ultimately, this knowledge can inform translational discoveries with potential for sorely needed regenerative therapies.<\/jats:p>","DOI":"10.3389\/fcell.2020.595896","type":"journal-article","created":{"date-parts":[[2020,12,23]],"date-time":"2020-12-23T00:51:43Z","timestamp":1608684703000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":61,"title":["The Ocular Neural Crest: Specification, Migration, and Then What?"],"prefix":"10.3389","volume":"8","author":[{"given":"Antionette L.","family":"Williams","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brenda L.","family":"Bohnsack","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2020,12,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"7","DOI":"10.1002\/jnr.24245","article-title":"Relationship between neural crest cell specification and rare ocular diseases.","volume":"97","author":"Akula","year":"2019","journal-title":"J.
