Bone resorption and bone formation occur in areas of compressive and tensile force action, respectively. The mechanism that causes such a difference in bone metabolism is still unclear. In this study, we investigated the difference in the osteoblastic calcium signaling response between compression and stretching mechanical stimuli. We applied two types of mechanical stimuli to osteoblast-like MC3T3-E1 cells: first microneedle direct indentation onto the cell as compression stimuli, and second stretching stimuli by using originally developed cell stretching MEMS device. Cells were treated with thapsigargin and calcium-free medium to investigate the source of the calcium ion. The results demonstrated variations in the osteoblastic calcium signaling response between the compression and stretching stimuli. The magnitude of an increase in the intracellular calcium ion concentration is much higher in the compression stimuli-applied cell group. Treatment of calcium-free medium nearly suppressed the calcium signaling response to both types of mechanical stimulation. Thapsigargin treatment induced an increase in the magnitude of calcium signaling response to the compression stimuli, while suppressed the slow and sustained increase in the calcium ion concentration in the stretching stimuli-applied cell group. These findings demonstrate the difference in the characteristics of osteoblastic calcium signaling response between compression and stretching mechanical stimuli.","PeriodicalId":51661,"journal":{"name":"Journal of Robotics and Mechatronics","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135568015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A spherical permanent magnet was selected to generate a consistent attractive force, enabling the robot to perform inverted locomotion under steel structures. Additionally, the robot’s foot tip was designed as a balljoint mechanism, providing flexibility in foot placement at any angle between the tip and surface. We also introduced an adjustable sleeve mechanism to detach the foot tip during locomotion by creating a fulcrum during the tilt and pull steps. This mechanism effectively reduced the reaction force based on the sleeve diameter. The experimental results showed a 46% decrease in the present load when using the adjustable sleeve mechanism compared to direct pulling. For inverted locomotion, a quadruped robot and a hexapod robot, which represent the predominant type of multi-legged robots, were constructed. We integrated the SMJ and adjustable sleeve into both robots, enabling them to perform inverted locomotion with various gaits such as crawling, trotting, square, and tripod gaits. Our analysis examined the characteristics of each gait in terms of velocity and stability, thereby confirming the versatility of the proposed SMJ, which can be applied to different types of legged robots.","PeriodicalId":51661,"journal":{"name":"Journal of Robotics and Mechatronics","volume":"70 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135568005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vivo tissues are complex arrangements of heterogeneous cells that interact with each other. To create such tissues in vitro, it is essential to develop a technique that arranges heterogeneous cells in an arbitrary configuration. Currently, we are developing a new gel patterning technique to create effective cell micropatterns by using photolithography and alginate gel, which inhibits cellular adhesion. In this study, we considered that a more flexible gel patterning technique was required for creating order-made formations of complex tissues. We created gel patterns by removing the alginate gel using laser processing, and cells were cultured on the formed patterns. Complex heterogeneous cell patterns were achieved by adjusting various technical parameters such as the laser power, spot diameter, and alginate gel film thickness. Based on our results, we anticipate that our technique will prove useful for the development of regenerative medicine and tissue engineering.","PeriodicalId":51661,"journal":{"name":"Journal of Robotics and Mechatronics","volume":"45 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135568009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
