Bergapten is a natural compound with the potential to regenerate bone. However, its poor solubility and instability hinder its clinical use. We developed bergapten-loaded long-circulating liposomes (BP-LCL) to overcome these challenges. The liposomes were spherical, stable, and highly effective at delivering bergapten. We found that BP-LCL were biocompatible and enhanced the osteogenic differentiation of human dental pulp stem cells. It did this by increasing key markers like RUNX2, COL1, and OCN, and by activating the Wnt/β-catenin signaling pathway. This study suggested that BP-LCL could be a promising new approach for bone regeneration settings.
