The role of vitamin K2 on osteoblastic functions by using stem cell model.

Vitamin K2 (MK4) functions were investigated by using the induced skin cell into osteoblast compared with the control media. The real time PCR measured gene expression in both cultures at the fourth, seventh, fourteenth, twenty first, twenty eighth, thirty fifth and forty second days of culture. The gene expressions of osteocalcin, osteonectin, osteopontin, bone sialoprotein, CBFA1, Interleukin-6, Estrogen receptors and collagen type) were monitored by real time PCR.
