Fig. 2From: Direct activation of platelets by addition of CaCl2 leads coagulation of platelet-rich plasmaDHM examination of changes in attachment area, optical thickness, and surface roughness of Ca2+-simulated platelets. Washed platelets were treated with 0.1% CaCl2 for 15 min (b, d) on culture flasks, fixed, and subjected to DHM examination. Control was no treatment at 2 min (a, c). Each platelet was plotted in the scatter plots of “Area vs. Thickness” (a, b) or “Roughness vs. Thickness”. Similar results were obtained from samples of two other donorsBack to article page
