摘要：Graphical abstractDisplay OmittedAbstractIn situfixation of adherent cells is a necessary process for downstream assays. Current methods to dissociate adherent endothelial cells require the use of a cell scraper that may introduce variability in nuclear morphology. Also, a cell scraper is not an option for experiments using sealed flow chambers. HMEC-1 cells were sheared at 5 dyn/cm2for 24 h and then fixedin situ, quenched, and dissociated at the same shear rate. Analysis revealed no statistically significant change in nuclear shape between the steps of fixation and dissociation. This method outlines an alternative for the dissociation of adherent sheared endothelial cells after being fixedin situin a micro-scale channel without causing a change in the nuclear morphology.•This method can be used with any commercially available, or custom-made, flow chamber and flow system.•Allows for downstream experimentation with adherent cells fixedin situ, such as Hi-C analysis, without impacting nuclear morphology or chromatin organization.•Cells are cultured, fixed, and dissociated at the same shear rate. Using the same shear rate for each step yields results that are not influenced by variable forces.
