Since the refinement and assembly of the first microscope by Galileo Galilei, the microscope has been at the center of critical discoveries in Science, particularly in the Biological and Life Sciences. Imaging capabilities of microscopes have advanced over the years and imaging systems routinely permit the examination of biological specimens from the molecular to whole organism level. Most studies have examined biological phenomena in fixed cells and tissues; however, recent advances in fluorescent tagging or conjugation of proteins have enabled researchers to monitor dynamic events as they occur in real time. The requested funds will be used for a live-cell imaging system with an on stage environmental chamber to enable time-lapse fluorescence imaging. A critical element to this unique imaging equipment is the extended time frame for monitoring cells and tissues under sterile and specimen-specific optimal growth conditions that is made possible with the on stage incubation chamber. This imaging system will allow us to (i) monitor interactions and coupling between extracellular signalling molecules such as hormones and their cell membrane-bound receptors; (ii) examine and characterize water-transporting channels known as aquaporins, critical for hydromineral balance; (iii) visualize abnormalities in energy metabolism through time-course studies on energy storage and dissipation; (iv) study gastrointestinal tract metamorphosis in fish and examine the influence of environmental change; and (v) elucidate temporal alterations in the physiology of the vertebrate tight junctions (TJ) complex in response to endocrine factors controlling the incorporation (or removal) of TJ proteins. This equipment will allow us to monitor biological interactions and events in living cells and organisms using fluorescent probes (e.g. green fluorescent protein, GFP). This state-of-the-art imaging system will significantly expand the research capacity of each of the co-applicants (across two separate Faculties, Science and Health). Most importantly, this system will be critical for HQP trainees to understand the dynamic nature of biological processes and the linkage between biological structure and function.

自从伽利略改进和组装了第一台显微镜以来，显微镜一直是科学，特别是生物和生命科学的关键发现的中心。 显微镜的成像能力多年来不断发展，成像系统通常允许从分子到整个生物体水平检查生物标本。 大多数研究已经检查了固定细胞和组织中的生物现象;然而，最近在荧光标记或蛋白质缀合方面的进展使研究人员能够监测动态事件，因为它们发生在真实的时间。 所请求的资金将用于带有舞台环境室的活细胞成像系统，以实现延时荧光成像。 这种独特成像设备的一个关键要素是延长了在无菌和细菌特异性最佳生长条件下监测细胞和组织的时间范围，这是通过台上孵育室实现的。 这一成像系统将使我们能够（i）监测细胞外信号分子如激素和它们的细胞膜结合受体之间的相互作用和耦合;（ii）检查和表征水转运通道，称为水通道蛋白，对水矿物平衡至关重要;（iii）通过对能量储存和耗散的时间过程研究，可视化能量代谢的异常;（iv）研究鱼类的胃肠道变态，并研究环境变化的影响;及（v）阐明脊椎动物紧密连接（TJ）复合体在控制TJ蛋白质掺入（或去除）的内分泌因素的反应中的生理学变化。该设备将使我们能够使用荧光探针（例如绿色荧光蛋白，GFP）监测活细胞和生物体中的生物相互作用和事件。这种最先进的成像系统将显着扩大每个共同申请人的研究能力（跨两个独立的学院，科学和健康）。最重要的是，这个系统对于HQP学员理解生物过程的动态本质以及生物结构和功能之间的联系至关重要。
