TABLE I.
Statistics on cell organization. Statistics in the different parts of fibronectin-coated tubes, without and with flow (0.15 μl/min for 1 day), are shown: mean, standard deviation, number of cells; in No. of tubes = 8 (without flow), 4 (flow on tube with change in diameter), plus 4 (flow in tube with constant flow). “stat diff from” indicate conditions with which a statistically significant difference with p < 10−4 was determined. Boldface values refer to mean values, italic values to indications about conditions with statistically significant differences.
