We present analysis tools which are formulated using wide-field interferometric phase microscopy measurements, and show their ability to uniquely quantify the life cycle of live cancer cells. These parameters are based directly on the optical path delay profile of the sample and do not necessitate decoupling the refractive index and the thickness in the cell interferometric phase profile, and thus can be calculated using a single-frame acquisition. To demonstrate the use of these parameters, we have constructed a wide-field interferometric phase microscopy setup and closely traced the full lifecycle of HeLa cancer cells. These initial results show the potential of the parameters to distinguish between the different phases of the cell lifecycle, as well others biological phenomena.
我们展示了利用宽场干涉相显微镜测量制定的分析工具,并展示了其独特量化活癌细胞生命周期的能力。这些参数直接基于样品的光程延迟分布,无需在细胞干涉相分布中解耦折射率和厚度,因此可以使用单帧采集进行计算。为了证明这些参数的用途,我们构建了一个宽场干涉相显微镜装置,并密切追踪了HeLa癌细胞的整个生命周期。这些初步结果显示了这些参数区分细胞生命周期不同阶段以及其他生物现象的潜力。
