myofibroblast cell connective tissue cell lymph node fibroblastic reticular cell 2022-03-21T15:24:01Z A specialized, fibroblastic reticular cell of mesenchymal origin found in lymph nodes. In human, it expresses several markers common to myofibroblasts (desmin, vimentin, CD73, CD90, α-smooth muscle actin (αSMA)), and can be differentiated from endothelial cells by its lack of CD31 expression. These cells are critical for the overall organization and function of the lymph node. Lymph node fibroblastic reticular cells (FRCs) can be further classified based on their location, function, and unique marker expression. fibroblastic reticular cell https://github.com/obophenotype/cell-ontology/issues/1472 Homo sapiens
