In the current study, we show that solely by aligning collagen fibers CD8+ T cell migration behavior can be augmented. Our study has allowed a direct comparison of CD8+ T cell migration in unaligned and … Websons. In our collagen matrices, the alignment of fibers decreased significantly when collagen density was increased from 1mg/ml to 1.5 mg/ml, but the average pore size did not change. That the mesh is not tighter, but is significantly less aligned likely explains the decrease in the elastic modulus from 1–1.5mg/ ml.
