Paracrine signaling via growth factor secretion by mesenchymal stem cells

Paracrine signaling via growth factor secretion by mesenchymal stem cells" does not refer to a specific molecular target but rather describes a process in which mesenchymal stem cells release soluble factors—primarily various growth factors like vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), fibroblast growth factor 2 (FGF2), insulin-like growth factor 1 (IGF1), transforming growth factor beta (TGF-beta), interleukin 8 (IL8)—that influence surrounding tissues. This paracrine activity is central to the therapeutic properties attributed to MSCs in regenerative medicine. The process involves activation of intracellular pathways such as NFκB and ERK/JNK in response to stimuli like TNF-alpha or hypoxia[1][3]. However, this entry does not correspond to an individual druggable target such as a receptor or enzyme; it is instead an umbrella term for multiple secreted molecules and their collective biological effects. Therefore it should not be considered a canonical therapeutic target itself[1][3].

Paracrine signaling is not a druggable target itself but refers to the mechanism where mesenchymal stem cells secrete various growth factors—such as VEGF, HGF, FGF2, IGF1—that act on neighboring cells to mediate tissue repair, angiogenesis, immunomodulation, and other processes[1][3].
