From: An in vitro assay of collagen fiber alignment by acupuncture needle rotation
Effects of crosslinking on area of alignment (average +/- standard error). The birefringent area of alignment was identified from image sets binarized based on the image at 2 revolutions. Needle rotation in crosslinked collagen gels generated less alignment than untreated collagen gels at each collagen concentration. The area of alignment increased with increasing collagen concentration for both untreated and crosslinked collagen.
