Within the limitation of this study, the results indicate for the first time that fibrin-hOMSC constructs are endowed with the constitutive capacity to develop into mineralized tissues that exhibit certain similarities to cementum and bone.
In this review we discuss the historical perspective of stem cell populations from oral tissues in light of our current understanding of stem cell biology. Stem cells and their niches have been identified in the periodontium starting from the late 1970s. Applying new criteria for the identification and characterization reveals that oral tissues comprise a multipotent primitive neural crest-like stem cell population capable of differentiating into neural crest derived cell lineages of the cranial-facial zone. This population supplies cells to a more restricted stem cell type with tissue specific epigenetic memory that differentiates into cell lineages characteristic of their tissue origin. We believe that the microenvironment plays an essential role in maintaining stem cell populations and directing their migration and differentiation, and that this factor needs to be considered for utilization of stem cell-based therapy for periodontal regeneration and regenerative dental medicine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
