Fiber-Induced Cell Initialization (FICI): Mechanotransductive and Bioelectrical Re-examination of the STAP Phenomenon via Conductive Piezoelectric Fiber Networks

The STAP cell phenomenon (2014) sought external-stimulus-driven cell initialization using weak acid. It could not be reproduced. This paper re-examines the phenomenon from a different angle: was the type of stimulus wrong? We propose that cell initialization occurs more naturally and reproducibly on conductive piezoelectric fiber networks delivering simultaneous triple stimulation: (1) Mechanotransduction — nanoscale groove structures (100-500nm) physically deform cells, deform nuclei, alter chromatin structure, and change gene expression toward pluripotency; (2) Bioelectrical stimulation — piezoelectric microcurrents alter membrane potential, open Ca2+ channels, and potentially induce Oct4/Sox2/Nanog expression; (3) Adhesion factor signaling — fibronectin/laminin coating activates integrin-FAK-ERK pathway, rewriting cell identity. The proposed initialization-to-muscle differentiation sequence: cell seeding on fiber network → triple stimulation → initialization-like state → fiber-directed myoblast differentiation → fiber encapsulation → contraction → muscle. This paper is the fifth layer of a unified invention series: ECCE (DOI: 10.5281/zenodo.20725907), CPMH (DOI: 10.5281/zenodo.20725945), SIBM (DOI: 10.5281/zenodo.20726036), GMFT (DOI: 10.5281/zenodo.20726125), FICI (this paper). Integrated with Genki-Meridian Fiber Theory: Qi flowing through fiber mesh initializes cells, cells wrap fibers, muscle forms — the physical mechanism of 'flesh originating from the Qi mesh.' Theoretical basis: V = N / D (Tendo Economics, Katayama 2026). Published as open knowledge base. To researchers with laboratories: build the fiber, seed the cells, observe.
