“…At a high resolution transmission electron microscopy (TEM), these CFs can be seen to have various diameters (Doughty, 2011). These fibrils of various sizes can be expected to have different properties in terms of strength and/or resistance to physical forces on the tissue in which they can be found (Eyden and Tzaphlidou, 2001; Franchi et al, 2007; Lavagnino et al, 2005; Ottani et al, 2001; Parry et al, 1978).…”
