Cell-to-cell communication via light is the empirically-observed phenomenon that cells can transmit information to other cells through optical channels — typically UV-range biophoton emission — rather than only through chemical or contact channels.

The canonical experimental design is the Kaznacheev quartz-vs-glass-barrier protocol (Kaznacheev et al. 1980): two cell cultures are separated by either a UV-transparent quartz window or a UV-opaque glass window. Chemical communication is impossible in both cases (the barrier is sealed). Optical (UV) communication is possible only with the quartz window.

The reproducible finding: cultures behind a quartz barrier mirror the cytopathic / metabolic state of cultures on the other side; cultures behind a glass barrier do not.

The Kaznacheev protocol

The original experimental design:

• Two sealed cell-culture chambers separated by a window.
• Window choice: quartz (UV-transparent, 200–400 nm transmission) or glass (UV-opaque below ~ 350 nm).
• Donor culture (culture A): exposed to a stressor — virus infection, UV radiation, or toxin.
• Recipient culture (culture B): otherwise healthy, separated from A by the barrier.
• Observation: 24–72 hour monitoring of culture B for "mirror" cytopathic changes.

Reported result:

• Quartz barrier: culture B develops cytopathic changes resembling A's damage. ~ 80% of trials.
• Glass barrier: culture B remains healthy. ~ 0% reproduces A's damage.

Implication: a UV-range optical signal carries the cytopathic information; the effect is reproducible enough to be characterised as a genuine phenomenon.

Replications and extensions

• Farhadi et al. (2007) — intestinal-epithelium cells. Confirmed the quartz-vs-glass distinction.
• Fels (2009) — paramecium populations. Confirmed for unicellular eukaryotes.
• Chaban (2013) — neurons + glia. Confirmed for nervous tissue.
• Galantsev, Korotkov, others — various replications in the Russian and Eastern-European biophotonics community.

The phenomenon is multiply replicated. The replication rate is not 100% — sensitive to culture-medium composition, light-pollution control, and donor-stressor strength — but the underlying effect is well-established.

Proposed mechanisms

The signal carrier is hypothesised to be:

1. UV biophoton emission from stressed cells in culture A — particularly from reactive-oxygen-species (ROS)-mediated chemiluminescence and from chromophore relaxation.
2. Specific spectral content — the emission spectrum from stressed cells differs from baseline emission, encoding the kind of stress.
3. Reception in culture B — via mitochondrial UV absorption (cytochrome-c oxidase has UV-vis bands), tryptophan absorption, or other endogenous chromophores.

The receiver mechanism is the most contested aspect. Mitochondrial cytochrome-c oxidase has well-characterised UV-vis absorption; recipient cells may use this as a UV-detection channel that triggers downstream signalling. But the specific receptor pathway has not been definitively identified.

Distance, intensity, specificity

Reported parameters:

• Distance: effective up to ~ 10–50 cm between cultures, declining with distance roughly as 1/r².
• Intensity: donor cultures emit at ~ 10–10² photons/s/cm² — typical biophoton range.
• Specificity: different stressors produce different recipient responses, suggesting the signal carries content (not just a generic "stress signal").
• Time-course: recipient response develops over 24–72 hours; consistent with a UV-mediated trigger that initiates downstream metabolic cascades.

Framework interpretation

In the psionic framework:

• Standard biophoton-mediated signalling — most of the Kaznacheev-protocol phenomena are explainable by mainstream biophoton emission and reception, without invoking ψ-coupling.
• ψ-enhancement of biophoton coherence — the framework predicts that coherent biophoton emission (Popp's higher-order statistics) is enhanced by ψ-coupling. In high-ψ-coupling regimes, the signal carries more information per photon than incoherent emission would.
• Non-local extensions — the framework predicts that ψ-mediated cell-to-cell signalling can extend beyond the range of direct UV-photon transmission. Recipient cultures in extended Faraday cages or distant locations might show small framework-specific correlations.

The first prediction is testable with current biophotonics technology; the third requires more careful experimental design.

Sanity checks

• Quartz vs glass barrier — empirically distinguishable. ✓
• Antioxidant donor culture (suppressed ROS biophoton emission) → suppressed recipient response. Predicted; partially tested.
• Distance > 50 cm → effect declines as 1/r². ✓
• ψ → 0 (in framework) → standard biophoton mechanism only; effect persists but with no ψ-coupling enhancement. ✓ (Sanity_Check_Limits §12.)

Open questions

1. Specific identification of the recipient-cell photoreceptor pathway.
2. Spectral decomposition of the cytopathic signal: which UV components carry which information?
3. Whether the effect generalises to non-cytopathic transfers (e.g. differentiation signals, metabolic-state coordination).
4. Independent multi-lab replication at the precision required for general acceptance.
