Harmine promotes odontoblastic differentiation of dental pulp stem cells.

Introduction: Dental pulp stem cells (DPSCs) have the potential to differentiate into various types of tissues including tooth, adipose, cartilage, muscle, nerve, and also possess regenerative properties. Harmine, a beta-carboline alkaloid, has been shown to have antitumor activities and promote bone formation through the differentiation of osteoblasts. The aim of this study was to investigate the effect of harmine on the differentiation of DPSCs into odontoblast cells.
