Tendon cell Tendon cell Tendon cells, or tenocytes, are elongated fibroblast type cells. The cytoplasm is stretched between the collagen fibres of the tendon. They have a central cell nucleus with a prominent nucleolus. Tendon cells have a well-developed rough endoplasmic reticulum and they are responsible for synthesis and turnover of tendon fibres and ground substance. Tendon cells form a connecting epithelial layer between the muscle and shell in molluscs. In gastropods, for example, the retractor muscles connect to the shell via tendon cells. Muscle cells are attached to the collagenous myo-tendon space via hemidesmosomes. The myo-tendon space is then attached to
Patellar tendon rupture weakness after the injury and repair. If the tendon rupture is a partial tear (without the two parts of the tendon being separated) then non-surgical methods of treatment may suffice. The future of non-surgical care for partial patella tendon ruptures is likely bioengineering. Ligament reconstruction is possible using mesenchymal stem cells and a silk scaffold. These same stem cells have been shown to be capable of seeding repair of damaged animal tendons. In 2010, a clinical study proved that mechanical loading of the tendon callus during the remodelling phase leads to healing by regeneration. Patellar tendon rupture Patellar tendon rupture
