Use cases
HNC PDO—not FaDu / Cal27 spheroids and not a full normal-mucosa expansion course.
| Use | Fit | Readout | Notes |
|---|---|---|---|
| HNSCC / salivary resection or biopsy PDO biobank + chemo/RT | Recommended | Genomic fidelity and RT sensitivity vs clinical response[1] | Millen / Driehuis biobank shows predictive potential especially in adjuvant RT settings. |
| Matched normal mucosa contrast | Contrast | Toxicity / selectivity | Keep normal and tumor dishes separate; do not mix drug plates. |
| FaDu / Cal27 spheroids as PDO | Do not mix | Spheroid diameter | Cell-line spheroids are not PDOs. |
In one line
HNC clusters → dome → EGF/Rspo niche → brief Y-27632 → mechanical split → CK/p53 → chemo/RT drugs.
Protocol overview
- Ethics + cold chain; log site (oral / oropharynx / larynx / hypopharynx / salivary) and HPV / smoking history
- Trim necrosis; collagenase ± Dispase to clusters; brief RBC lysis (MC427) if bloody
- Matrix domes; epithelial niche (EGF, FGF, Noggin, R-spondin ± Wnt, A83-01…)[[1]][[2]]
- Brief Y-27632; score cystic vs solid growth
- Feed every 2–3 days; mechanical split; bank SCC vs salivary separately
- CK, EpCAM, p53; mycoplasma; match the primary
- Drug / RT arms with vehicle; in vivo uses transplant SOPs—not this page
