Background: Laminin alpha 3/Laminin-5

Laminins are heterotrimeric, noncollagenous glycoproteins composed of alpha, beta and gamma chains. Through interactions with Integrins, Dystroglycan and other receptors, Laminins contribute to cell differentiation, cell shape and migration, and maintenance of tissue phenotypes and survival (1). Laminin-5, also known as Epiligrin, consists of an alpha 3, beta 3, and gamma 2 chain. It is abundant in transitional epithelium, stratified squamous epithelia, lung mucosa and other epithelial glands and plays an important role in the initiation and maintenance of epithelial cell anchorage to the underlying connective tissue (2, 3).
