The scope of our research is directed towards lifestyle mechanobiology, specifically the behavior of cells where mechanical stress is applied. We are investigating the intracellular signaling in single cells. The proposed FMPA system utilizes fluorescence imaging combined with mechanical stimuli.
That is, the aspiration pressure. There are currently further advancements that have attempted to combine more than two techniques with the microaspiration setup like microfluidics or image analysis software. Current experimental challenges lie with the fact that the setup is quite labor intensive and is operator dependent.
As the system is manually operated, there are inconsistencies that arise in specific steps. For example, filament preheating. The findings of research demonstrated there was a corresponding increase in the influx of calcium ions into the RBCs when the pressure was incrementally increased between negative 10 millimeter mercury to negative 40 millimeter mercury.
This suggests that RBCs poses the ability to sense changes in their mechanical environment and respond by rapid calcium-related channel activities. This study places particular emphasis on the application of FMPA as a crucial tool for unveiling the nuanced mechanosensitive responses showcased by RBCs under varying stimuli.
