Cell alterations during isolation and preparation for flow cytometry cell sorting by antibodies, temperature, homogenization, buffer composition and mitogens are well known. In contrast, little is known about cell alteration caused by the instrument or the sorting process itself. We systematically evaluated cellular responses to different sorter-induced physical forces. In summary, flow cytometry cell-sorting induced forces can affect cellular signaling cascades, especially the MAPK p38. Functional assays, related to the p38 MAPK pathway, of human primary T cells after flow cytometry sorting did lead to minor physiological modulation but no functional impairments.
