Cats have fine, sharp teeth and, despite having a weaker bite than dogs, inflict deep puncture wounds inoculated with saliva, and are capable of penetrating bone, joints, and tendons. Exchanges. Since SHED are homologous to the central nervous system, they possess superior capacity to differentiate into neural cells. I doubt he would. The finding may lead to new approaches to develop low-cost, non-invasive therapies for treating dental disease and tooth damage. Furthermore, human A. vis- cosus strains may be more sensitive to growth inhi- bition by factors in saliva (Arnold et al., 1979). The question is about the function of teeth.
