Basal Lamina of the Dental Epithelial Attachment

At the base of a gingival sulcus, the junctional epithelium mediates the epithelial attachment. This epithelium possesses two basal laminas, an outer one that is continuous with the sulcular epithelium around the free gingiva and an inner one which mediates the actual 

In addition to integrin a6P4, epidermal basal cells, which include junctional epithelial cells, possess two pi integrins that affect subsequent basal cell differentiation (Sect. 5.2.2). The pi integrins transmit inside-out signaling via kindlin-1, a protein that binds to the
