使用转基因方法标记心脏固有壁使用高速线扫描捕获心脏固有壁的位置创建X与时间图以可视化和量化成像期间的收缩。黑腹果蝇是一个强大的模式生物,其中解决心脏模式和心脏发育的遗传。该系统允许将实时成像与无数可用的遗传和转基因技术配对,不仅可以识别对心脏发育至关重要的基因,还可以评估它们对生物体心脏功能的影响。有几种描述的方法来评估果蝇的心脏功能。然而,这些方法仅限于成像的中期至晚期幼虫和成人的心脏。因此,这一技术障碍不允许记录和分析携带强突变的胚胎中的心脏功能,这些胚胎不会孵化成幼虫。我们的技术创新在于转基因标记果蝇心脏的细胞,并使用基于线扫描的共聚焦成像来重复成像心脏的壁。通过将该线扫描绘制为记波图,可以可视化和测定心脏收缩,从而允许对生理缺陷进行量化。该方法可用于从影响心脏发育但不能孵化成幼虫的已知突变中获得生理数据以用于常规分析。
Use transgenic methods to label heart proper walls Use high-speed line scanning to capture position of heart proper walls Create X vs. time plot to visualize and quantify contractions over imaging period. Drosophila melanogaster is a powerful model organism in which to address the genetics of cardiac patterning and heart development. This system allows the pairing of live imaging with the myriad available genetic and transgenic techniques to not only identify the genes that are critical for heart development, but to assess their impact on heart function in living organisms. There are several described methods to assess cardiac function in Drosophila. However, these approaches are restricted to imaging of mid- to late-instar larval and adult hearts. This technical hurdle therefore does not allow for the recording and analysis of cardiac function in embryos bearing strong mutations that do not hatch into larvae. Our technical innovation lies in transgenically labeling the cells of the Drosophila heart and using line scan-based confocal imaging to repeatedly image the walls of the heart. By plotting this line scan as a kymograph, heart contractions can be visualized and assayed, thereby allowing for quantification of physiological defects. This method can be used to obtain physiological data from known mutations that affect cardiac development yet are incapable of hatching into larvae for conventional analysis.
