However, the effects of PTH on iPSCs remain mostly unknown. The purpose of this study was to investigate in vitro effects of parathyroid hormone (PTH) on osteoblastic differentiation of induced pluripotent stem cells (iPSCs) in a 3D culture model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Following embryoid body (EB) induction from mouse iPSCs (miPSCs), dissociated cells (miPS\u2010EB\u2010derived cells) were seeded onto atelocollagen sponge (ACS) in osteoblast differentiation medium (OBM). Cell\u2010ACS constructs were divided into three groups: continuous treatment with human recombinant PTH (1\u201034) (PTH\u2010C), intermittent PTH treatment (PTH\u2010I) or OBM control. To confirm the expression of PTH receptor\u20101(PTH1R), the expression of <jats:italic>Pth1r<\/jats:italic> and cAMP production over time were assessed. Real\u2010time PCR was used to assess the expression of genes encoding osterix (<jats:italic>Sp7<\/jats:italic>), runt\u2010related transcription factor 2 (<jats:italic>Runx2<\/jats:italic>), collagen type 1 (<jats:italic>Col1a1<\/jats:italic>), and osteocalcin (<jats:italic>Bglap<\/jats:italic>) at different time points. Mineralization was assessed by von Kossa staining. Histochemical staining was used to analyze alkaline phosphatase (ALP) activity, and immunolocalization of SP7 and BGLAP was analyzed by confocal laser scanning microscopy (CLSM).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>On days 7 and 14, expression of the <jats:italic>Pth1r<\/jats:italic> in miPS\u2010EB\u2010derived cells was increased in all groups. Production of cAMP, the second messenger of the PTH1R, tended to increase in the PTH\u2010I group compared with PTH\u2010C group on day 14. Expression of <jats:italic>Col1a1<\/jats:italic> in the PTH\u2010I group on day 14 was significantly higher than other groups. There was a time\u2010dependent increase in the expression of <jats:italic>Sp7<\/jats:italic> in all groups. On day 14, the expression level of <jats:italic>Sp7<\/jats:italic> in the PTH\u2010I group was significantly higher than other groups. In von Kossa staining, the PTH\u2010I group showed higher level of staining compared with other groups on day 14, whereas the level was slightly attenuated in the PTH\u2010C group. In histochemical staining, ALP\u2010positive cells were significantly increased in the PTH\u2010I group compared with other groups on day 14. In CLSM analysis, the numbers of SP7\u2010 and BGLAP\u2010positive cells showed a gradual increase over time, and on day 14, a significantly greater SP7 expression was observed in the PTH\u2010I group than other groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These results suggested that the intermittent PTH treatment promotes osteoblastic differentiation and
