The motility of spermatozoa has been shown to be associated with their structural integrity and supplemental energy (Figures 2A and 2B). , To test whether the low motility of Ccdc176−/− spermatozoa is related to defects in the flagellar structure, we examined the flagellar ultrastructure of spermatozoa in the cauda epididymis using transmission electron microscopy (TEM). Ccdc176−/− spermatozoa had normal structural organization in the mitochondrial sheath (MS) and plasma membrane (PM) (Figure 2C).

Wound closure is a fundamental process in many physiological and pathological processes, but the regulating effects of external force on the closure process are still unclear. Here we systematically studied the closure process of wounds of different shape under cyclic stretching. We found that the stretching amplitude and direction had significant effect on the healing speed and healing mode. For instance, there was a biphasic dependence of the healing speed on the stretching amplitude.
