Microtracks can be reproducibly patterned with a range of collagen densities. (A) Confocal reflectance image reflecting the measured dimensions of patterned collagen tracks. Scale bar = 50 μm. Length (B), width (C), and depth (D) are quantified across tracks patterned in 1.5 – 5 mg/mL type I collagen. Mean ± SD; * indicates p < 0.05; n > 45 tracks, 2 independent experiments; dotted lines indicate length and width of original patterned silicon master.
