Global cellular and tissue-level regenerative pathways

Global cellular and tissue-level regenerative pathways encompass the integrated network of signaling cascades and epigenetic mechanisms that coordinate the repair, replacement, and restoration of biological structures following injury or aging (Gurtner et al., 2008, Nature). These pathways include highly conserved developmental systems such as Wnt, Notch, Hedgehog, and Hippo signaling, which collectively regulate stem cell potency, cell proliferation, and tissue patterning (Clevers et al., 2014, Science). In a therapeutic context, the modulation of these pathways aims to reverse degenerative conditions or enhance wound healing by activating endogenous repair mechanisms or inducing cellular reprogramming (Takahashi & Yamanaka, 2006, Cell). However, because these pathways are frequently hijacked during oncogenesis, a primary challenge in drug development is achieving precise control to avoid promoting tumor growth or uncontrolled fibrosis (Nusse & Clevers, 2017, Cell). Consequently, this term represents a broad biological category and therapeutic area rather than a single, specific molecular target.
