Fig. 8From: Design and testing of a centrifugal fluidic device for populating microarrays of spheroid cancer cell culturesSpheroid centroid distribution for sample 2 using the same coordinate system as that used in Fig. 7a. The magenta markers represent centroid locations and do not indicate spheroid volume. While not indicative of sectionability, a locally weighted regression was added to highlight the non-planar trends in the distribution (R2=0.87)Back to article page
