Popis: In osteoclast activity during space flight, inconsistent results have been reported in an in vivo study while osteoblastic function is consistently reduced by space flight. Bone matrix is an important function in the response to physical stress. However, there is no suitable in vitro co-culture system of osteoblasts and osteoclasts including bone matrix. On the other hand, fish scale is a calcified tissue that contains osteoblasts, osteoclasts, and bone matrix, all of which are similar to those found in human bones. Recently, we developed a new in vitro model system using goldfish scale. This system can be used to simultaneously detect the activities of both scale osteoclasts and osteoblasts with tartrate-resistant acid phosphatase and alkaline phosphatase as the respective markers and precisely analyze the co-relationship between osteoblasts and osteoclasts. In our co-culture system, osteoblasts and osteoclasts reacted sensitively to several degrees of acceleration, ultrasound stimulation, and micro-gravity of 3D clinostat. Therefore, we strongly believe that our in vitro co-culture system is suitable model for the analysis of bone metabolism under micro-gravity, such as that experienced in space flight.
