[Abstract] This method allows evaluating the relative adhesion strength between T lymphocytes and specific adherent target cells using a shear force in flow chambers. It is based on the measure of the resistance of conjugates formed between T cells and adherent tumor cells to shear stress in a microfluidic system. For this purpose, T cells, stained with a CellTracker probe, are added into flow channels containing a monolayer of adherent target cells and their progressive detachment under a constant shear stress is then recorded using a fluorescent microscope.
[摘要] 该方法允许使用流动室中的剪切力评估T淋巴细胞和特异性粘附靶细胞之间的相对粘附强度。 其基于在微流体系统中T细胞和粘附的肿瘤细胞之间形成的缀合物对剪切应力的抗性的测量。 为此，将用CellTracker探针染色的T细胞加入含有单层粘附靶细胞的流动通道中，然后使用荧光显微镜记录在恒定剪切应力下的其逐渐分离。
