Multiple tissue repair-related genes and pathways

Multiple tissue repair-related genes and pathways encompass a diverse array of molecular mechanisms responsible for restoring cellular structure and function following injury (Gurtner et al., 2008, Nature). These pathways include the Wnt/beta-catenin, TGF-beta, Notch, and Hedgehog signaling cascades, which collectively regulate cell proliferation, migration, and the synthesis of the extracellular matrix (NIH, 2023). In a healthy physiological state, these genes are tightly regulated to ensure orderly healing; however, their chronic activation or suppression is linked to diseases such as pulmonary fibrosis, chronic diabetic ulcers, and various cancers (StatPearls, 2023). Therapeutic interventions often target specific growth factor receptors, such as PDGFR or VEGFR, to accelerate healing or use inhibitors like pirfenidone to mitigate excessive scarring (PubMed, 2022). Because these pathways are fundamental to development and tissue homeostasis, drugs targeting them must balance efficacy in repair with the risk of promoting oncogenesis or systemic toxicity (Journal of Clinical Investigation, 2021).
