    Abstract:
    Although safflower seeds have long been used in Korea as herbal medicines, very little research has been published on the effects of safflower seed on bone formation or bone density. The study reported here therefore examined bone nodule formation, calcium uptake, alkaline phosphatase activity, and intracellular concentration of calcium ion [Ca(2+)](i) in murine osteoblastic cells of the MC3T3-E1 line that were cultured on modified Eagle's minimal essential medium alone (controls) or with addition of 0.1% crude extract of safflower seed (experimental group I) or 0.1% aqueous fraction of safflower seed (experimental group II). Fluorescence spectrometry measurement of ([Ca(2+)](i)) showed significantly accelerated rates of osteoblast differentiation in experimental group I (3 microL of crude extract in 8 x 10(4) cells) and experimental group II (2 microL of aqueous fraction in 8 x 10(4) cells) compared to the control group.
