Figure 3: Medulla–cortex re-organization after implantation of thymus epithelial grafts in vivo. Figure 4: Medullary islets arise in thymus stromal cell grafts generated from two different donor ...

The thymus is roughly divided into two main regions, the medulla and the cortex. It has previously been unclear whether the cortex is involved in negative selection, or whether this process is ...

Mainly composed of epithelial cells, lymphocytes, and dendritic cells, the thymus comprises two parts – medulla and cortex. The epithelial cells, known as TECs (thymic epithelial cells), are ...

The generation of multiple microenvironments in the thymus, such as the cortex and the medulla, requires crosstalk signals from developing thymocytes. Lympho–stromal interactions in multiple ...

The thymus is a soft gland with two lobes. Each lobe has a central par, known as the medulla, and an outer part, known as the cortex. It is large in infants and young children, but it decreases in ...

In the thymus, it's possible to view cells 400 ... halt their wanderings and make a beeline out of the cortex to the medulla, something immature T cells can't do. The scenario they've ...

showed how the ratio of compartments in the thymus—known as the cortex and the medulla—changes with age. The researchers showed that structures called Hassall's bodies appear early during ...
