Figure 11From: An in vitro assay of collagen fiber alignment by acupuncture needle rotationFrequency sweep of collagen gels under 1% controlled strain (average +/- standard error). (A) Storage Modulus; (B) Loss Modulus. Both the storage and loss moduli demonstrated significant increases with increasing collagen concentration and crosslinking (2-way ANOVA, P < 0.001). Key: c: crosslinked, u: untreated.Back to article page
