Abstract

A fair comparison of multiple live cell cultures requires examining them under identical environmental conditions, which can only be done accurately if all cells are prepared simultaneously and studied at the same time and place. This contribution introduces a multiplexed lensless digital holographic microscopy system (MLS), enabling synchronous, label-free, quantitative observation of multiple live cell cultures with single-cell precision. The innovation of this setup lies in its ability to robustly compare the behaviour, i.e., migratory pathways, of cells cultured or contained in different ways (with varied stimuli applied), making it a valuable tool for dynamic biomedical diagnostics on a cellular level. The system's design allows for potential expansion to accommodate as many samples as needed, thus broadening its application scope in future quantitative diagnostics on global multi-culture cellular behaviours via their localized single-cell spatiotemporal optical signatures. We believe that our method has the potential to empower reliable live cell multi-culture comparisons through simultaneous quantitative imaging, enhancing label-free investigations into cell cultures and the effects of biochemical or physical stimuli over large areas, and unlocking novel mechanistic understandings through high-throughput time-lapse observations.

具有单细胞精度的多培养无标记定量细胞迁移传感。
多个活细胞培养物的公平比较需要在相同的环境条件下进行检查,只有当所有细胞同时制备并在同一时间和地点进行研究时,才能做到准确。这一贡献介绍了一个多路无透镜数字全息显微镜系统(MLS),使同步,无标签,定量观察多个活细胞培养与单细胞精度。该装置的创新之处在于它能够稳健地比较以不同方式培养或包含的细胞(应用不同的刺激)的行为,即迁移路径,使其成为细胞水平上动态生物医学诊断的有价值的工具。该系统的设计允许潜在的扩展,以容纳尽可能多的样本,从而扩大其应用范围,未来定量诊断全球多培养细胞行为通过其局部单细胞时空光学特征。我们相信,我们的方法有潜力通过同时定量成像,增强对细胞培养和大面积生化或物理刺激影响的无标记研究,并通过高通量延时观察解锁新的机制理解,从而实现可靠的活细胞多培养比较。
