'''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:

# '''UV biophoton emission''' from stressed cells in culture A — particularly from reactive-oxygen-species (ROS)-mediated chemiluminescence and from chromophore relaxation.
# '''Specific spectral content''' — the emission spectrum from stressed cells differs from baseline emission, encoding the kind of stress.
# '''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 [[Psionics|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 ==

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