Figure 1. Numbers of pulses for the extrusion of 1 mL ultrapure water and MTT assay at different air pressures, internal diameters, and cell suspension
densities. (A–F) Examination of the numbers of pulses at different air pressures (2–20 psi) with internal needle diameters of 0.41 (A), 0.34 (B), 0.3 (C),
0.26 (D), 0.23 (E), and 0.18 mm (F). (G–I) The cell viability of HEKs was examined at different air pressures (G), internal diameters (H), and different cell
suspension densities (I). (J–L) The cell viability of HDFs was examined at different air pressures (J), internal diameters (K), and different cell suspension
densities (L). The results are presented as the mean ± standard deviation; A–F, n = 3, and for G–L, n = 6. Abbreviations: HDFs, human dermal fibroblasts;
HEKs, human epidermal keratinocytes.
