Cellular Reprogramming as the Subtraction of a Retained Difference

Cellular reprogramming has conventionally been understood as an additive, rewind-like operation: adding reprogramming factors to a differentiated state in order to return it to an undifferentiated one. This paper reverses that directionality. Reprogramming is described here as the process by which subtracting the retention (epigenetic marks) that locks in differentiation causes the state to self-referentially reconstruct, regenerating a phase devoid of information. When the four generative phases of the Interference-Based Generative Theory (Kyōzai-shiki)—difference → retention → circulation → return—are taken as the vertical axis, previously disparate iPS reprogramming measurements fall uniquely into each phase, and structural predictions match empirical values. Specifically: (Difference) p53 suppression raises efficiency approximately 10-fold to approximately 20%, enabling reprogramming even of terminally differentiated cells; (Retention) demethylation in iPS proceeds over days to weeks in a sustained manner (instantaneous in oocyte nuclear transfer); (Circulation) a transient wave of aberrant hypermethylation arises and converges; (Return) the DNA sequence remains unchanged—only the “usage,” i.e. the epigenome (retention), is operated upon, and pluripotency is regenerated. This paper asserts no novel experimental facts. It rebundles known numerical data under the single generative structure of the four phases, providing a theoretical description that closes the procedure on paper: “numerically, reprogramming is completed by this sequence of steps.”
