Research Abstract

We have examined the mechanism of three types of stem cells differentiation to odontoblasts for the purpose of dentin regeneration. Morphological analysis indicated that retinoic acid and BMP-4 induced differentiation to the odontogenic pathway. Differentiated cells showed markers of odontoblast differentiation. Moreover, we found significant integrin α2β1 and αVβ3 expression with increased adhesion and motility on laminin-1 and collagen type-I substrates.
