Research Abstract

We found that BIO, a glycogen synthase kinase-3 (GSK3) inhibitor, induced changes in cell morphology, and promoted the expression of Nanog mRNA, considered the key gene to pluripotency, in mouse dental papilla derived mesenchymal (mDP) cells. When the BIO treated mDP cells were cultured in osteogenic differentiation medium, the expression of osteoblast maker genes and alkaline phosphatase activity were progressively increased.
