FNregi

FNregi is a fictional technology concept used in speculative biology and science fiction to describe a programmable gene-regulation system that, in-universe, triggers tissue regeneration. The term appears in various works of fiction and worldbuilding settings, and it is not a real-world technology.

Concept and mechanism: In these depictions, FNregi comprises a regulatory network that modulates gene expression and chromatin states to re-enter developmental programs for regeneration. It is typically portrayed as controlled by an external interface, an artificial intelligence, or a medical device, with built-in safeguards to prevent overgrowth or oncogenesis. Deliveries may involve engineered viral vectors, nanoparticles, or ex vivo cell modification. Because FNregi is fictional, its technical details vary between authors and settings.

Applications and limitations: In stories, FNregi enables rapid healing of wounds, limb regeneration, or organ repair. In-world ethics centers on equitable access, long-term safety, and potential misuse for enhancement or as a weapon. Real-world scientists and readers generally treat FNregi as a narrative device rather than a feasible technology, noting that actual gene regulation and regenerative medicine face different scientific and regulatory challenges.

Origins and usage: The concept commonly appears in near-future or military sci-fi settings, sometimes linked to pioneering research institutes or think tanks within a fictional universe. Variants such as FNregi-Prime or FNregi-Core are used to denote different generations or control architectures within those stories.
