endoteliumtomesenchyme

Endothelomesenchyme refers to a developmental process where endothelial cells, which form the lining of blood vessels, undergo a transformation into mesenchymal cells. Mesenchymal cells are a type of undifferentiated connective tissue cell that can differentiate into various cell types, including fibroblasts, osteoblasts, chondrocytes, and adipocytes. This transition, known as endothelial-mesenchymal transition (EndMT), is crucial for several physiological and pathological processes.

During embryonic development, EndMT plays a vital role in the formation of various tissues and organs. For example, it is involved in the development of the heart, blood vessels, and facial structures. In adult organisms, EndMT is typically suppressed but can be reactivated under certain conditions, such as wound healing and tissue repair. However, aberrant EndMT has been implicated in the progression of various diseases, including fibrosis, cancer metastasis, and cardiovascular diseases.

The molecular mechanisms underlying EndMT are complex and involve the activation of specific signaling pathways and transcription factors. These pathways often include those activated by growth factors like transforming growth factor-beta (TGF-β). The loss of endothelial cell junctions and the acquisition of migratory and invasive properties are hallmarks of EndMT. Understanding EndMT is of significant interest for developing therapeutic strategies targeting diseases where this transition contributes to pathology.
