Regeneration is a biological process by which organisms restore or replace lost or damaged tissues, organs, or body parts through controlled cell proliferation, differentiation, and patterning. It involves activation of resident stem or progenitor cells, dedifferentiation of mature cells in some taxa, and re-establishment of appropriate positional information via morphogen gradients and signaling pathways such as Wnt, FGF, BMP, and Notch. Regeneration can be epimorphic, with blastema formation and large-scale pattern reconstruction, or morphallactic, involving extensive tissue remodeling. Its extent and fidelity are species- and tissue-specific, constrained by genetic programs, immune responses, and age-dependent changes in cellular plasticity.
