Exploration of the Pressurization Condition for Killing Human Skin Cells and Skin Tumor Cells by High Hydrostatic Pressure

Figure 2

Phase-contrast micrographs of the cells in the control group and after HHP. (a) HEKas, (b) HDFas, (c) ASCs, (d) HEMa-LPs, and (e) MMs. The left column shows the micrographs of cells in the control group at 3 h, 1 day, 3 days, and 7 days after incubation, from top to bottom. The center-left column shows the micrographs of cells after HHP at 150, 160, 170, 180, and 190 MPa for 1 s (left to right) at 3 h 1 day, 3 days, and 7 days after incubation, from top to bottom. The center-right column shows the micrographs of cells after HHP for 2 min, and the right column shows the micrographs after HHP for 10 min. Cells in the red frame are detached and floating. Scale bars = 50 μm.
