我们报道了一种微流控定位室(MPC),它可以快速重复地重新定位显微镜载物台上的同一成像区域。微流控室的“顶部”印有一系列坐标数字,这些坐标数字充当附着在微流控室的“底部”上生长的哺乳动物细胞的定位标记。MPC细胞培养室提供了一种简单的解决方案,用于在数天或数周内跟踪相同的细胞或细胞组。定位标记用于将同一成像区域的延时图像配准到单像素精度。使用MPC细胞培养室,我们使用明场和荧光成像跟踪单个PC12细胞的迁移、分裂和分化超过一周。
We report a microfluidic positioning chamber (MPC) that can rapidly and repeatedly relocate the same imaging area on a microscope stage. The “roof” of the microfluidic chamber was printed with serials of coordinate numbers that act as positioning marks for mammalian cells that grow attached to the “floor” of the microfluidic chamber. MPC cell culture chamber provided a simple solution for tracking the same cell or groups of cells over days or weeks. The positioning marks were used to register time-lapse images of the same imaging area to single-pixel accuracy. Using MPC cell culture chamber, we tracked the migration, division and differentiation of individual PC12 cells for over a week using bright field and fluorescence imaging.
