Abstract: The effect of Lentinula edodes water extract (LE) on two osteoblastic cell cultures (HOS 58 and Saos-2) was investigated to determine if this edible medicinal mushroom has osteoinductive properties. Activity of alkaline phosphatase and mineralization were used as indicators for the vitality and maturation of the bone cells. Cultivation of human osteosarcoma cells HOS 58 for five days in presence of a serial dilution of the aqueous extract of L. edodes (0.8 μg/mL-125 μg/mL) resulted in a significant elevation of alkaline phosphatase activity (ALP) of the cells in comparison to untreated cells. Saos-2 cells, incubated with LE (20 μg/mL) and β-glycerol phosphate (2 mM) for 21 days, displayed a 2 fold level of mineralization than cells cultured soley with the positive control, β-glycerophosphate. The obtained results clearly indicate the activity of LE as a bone inducing agent in vitro. Therefore, the shiitake mushroom (L. edodes) deserves attention as a supportive dietary treatment or nutraceutical in the case of diseases accompanied with bone disorder, such as osteoporosis, osteopenia, and late complication of diabetes.
