(a) Percentage of NIH 3T3 cells, delivered as viable cells, after ejection at 150 μl/min using various needle gauges and lengths. Results are mean values ± SEM% (n = 3). Asterisks represent significant difference between samples and control, and ¥ represent significant difference between needle lengths (Short (SH) = 20 mm; Long (L) = 51 mm) of the same needle gauge, using the Kruskal–Wallis test. (b) Proliferation of NIH 3T3 cells ejected at 150 μl/min using different needle gauges and lengths (mean values ± SEM). Asterisks represent significant difference between samples (P < 0.05) and control. DP, directly plated control. (c) Percentage of NIH 3T3 cells, delivered as viable cells, 6 h following ejection at various flow rates using 30G and 34G 20‐mm needles. Results are normalised mean values to control ± SEM (n = 3). Asterisks indicate statistically significant differences between control and ejected samples using the Kruskal–Wallis test (P < 0.05).
