In addition to solitary SIF cells and clusters of SIF cells reported previously, a new structure of SIF cells was found and named ''SIF-cell nodule''. The SIF-cell nodule was composed of a large number of SIF cells and was encapsulated by dense connective tissue. Some blood vessels and nerve fibers entered the nodule. Based on the morphology, we speculated that SIF-cell nodule might be an endocrine gland.展开更多
