Thymus stromal cells information


Thymus stromal cells are subsets of specialized cells located in different areas of the thymus.[1] They include all non-T-lineage cells, such as thymic epithelial cells (TECs), endothelial cells, mesenchymal cells, dendritic cells, and B lymphocytes, and provide signals essential for thymocyte development and the homeostasis of the thymic stroma.[2]
