癌症研究
癌症是一种复杂的异质性疾病，由于细胞生长失控而引起。 一个或一组细胞的基因和表观遗传的变化破坏了正常功能，导致细胞自发、不受控制地生长和增殖。
模式生物研究
模式生物是研究人员用来研究特定生物学过程的物种。 它们具有与人类相似的遗传特征，通常用于遗传学、发育生物学和神经科学等研究领域。 选择模式生物的原因通常是它们在实验室环境中易于保持和繁殖、生成周期短，或能够产生突变体来研究某些性状或疾病。

如何形成清晰的图像
在显微镜检查中，景深常被看做经验参数。在实际操作中，会根据数值孔径、分辨率和放大率之间的相关性确定该参数。为了获得最佳视觉效果，现代显微镜的调节设备在景深和分辨率之间实现了最佳平衡，这两个参数在理论上呈负相关。
