Research Abstract |
While perlecan disappers from basal membrane of Hertwig's Epithelial Root Sheath (HERS) along with a progression of dental root formation, heparanase which is one of the digestion enzymes of perlecan migrates to epithelium cells of HERS. During the digestion process of perlecan by heparanase, Sonic Hedgehog (SHH) is cleavaged as a secreted protein. Therefore, we hypothesized that SSH might play a crucial role to establish dental roots.Despite the fact that many approaches have been employed to establish the dental root formation in vitro, it was struggling to reveal this interaction yet. The longer incubation time and the usage of a different type of culture circumstance did not help to improve our goals. More explorations will be essential to achieve the dental root formation by extracellular environment in order to investigate the interaction between perlecan and SHH.
