(A) Detrusor smooth muscle region of a spinal cord injury minipig (SCT) with red stained type I collagen and blue stained type III collagen fibres in the extracellular matrix photographed with a special polarization filter. Combined Haematoxylin and Herovici’s staining protocol. The scale bar represents 2.5 mm. (B) Types I and III collagen percentage in healthy reference minipigs (CTL) and SCT. The difference between types I and III collagen between CTL and SCT are both highly significant (**P<0.0001). X-axis: groups; Y-axis: percentage of either collagen I or III (%). Values are presented as mean±standard deviation. MT, smooth muscle tissue.
