Overview
This project collects questions about mitochondrial transfer between cells. The focus is not only whether transfer occurs, but what kind of evidence can distinguish functional transfer from proximity, debris, uptake, or imaging artifact.
Core Question
What evidence distinguishes functional mitochondrial transfer from coincident organelle proximity, vesicle debris, or stress-induced imaging artifacts?
Why This Matters
Mitochondrial transfer is biologically attractive because it suggests a direct route for cellular rescue. That attractiveness also makes the evidence standard important. Strong claims need route, recipient state, and functional consequence.
Current Understanding
The current model is evidence-first. A convincing case should connect transfer route, donor cell, recipient cell, and functional readout. Rescue phenotypes should be interpreted separately from direct mechanism.
Evidence / Signals
- Live imaging of a transfer route.
- Recipient-cell mitochondrial function after transfer.
- Perturbations that disrupt the proposed transfer route.
- Controls for phagocytosis, debris uptake, and cell fusion.
Tensions / Uncertainties
- Imaging can show proximity without proving transfer.
- Functional rescue can occur through multiple mechanisms.
- Stress conditions may create artifacts that look mechanistically meaningful.
Open Problems
- Which transfer routes are most reproducible across systems?
- What is the strongest minimal evidence package for functional transfer?
- How can experiments separate transfer from broader stress signaling?
