The thymus is the primary organ responsible for generating functional T cells in vertebrates. Although T cell differentiation within the thymus has been an area of intense investigation, the …

Therefore, in this writing we have concentrated our efforts in providing an overview of the embryology and anatomy of the thymus as well as putting the normal histology and …

Here we demonstrate, via spatial and temporal expression analyses, that the genetic mechanisms known to regulate mouse thymus organogenesis are conserved in humans. In addition, we …

The microscopic components of the mature thymus derive from several sources: epithelial derivates from the pharyngeal wall, mesenchyme, hemolymphoid cells, and vascular tissue. …

The thymus is derived from pharyngeal region; a region from which, in case of aquatic vertebrates, the gills develop. According to the classical hypothesis, the epithelial thymus …

The thymus gland, while providing thymus-processed T-lymphocytes to the entire body, also produces some special humoral secretions and may thus also be regarded as an endocrine …
