DA release 76 pg/mL (vs 2D 12, 3D static 28). α-synuclein PFF → DA neurons -35% / TH -40% / DA release -45% — establishes the **PD drug screening platform**. Shear-stress 15x lower than orbital shaking (0.13 dyn/cm² vs 2.03 dyn/cm²). Synthesis at [`/sources/literature-raji-2026-deepread.md`](/sources/literature-raji-2026-deepread.md).

The framework is the **direct next-generation design reference** for 3Brain's current 4096-electrode Accura-3D; Robin should sell Accura-3D as the existing best-in-class and Liu 2026 as the forward-looking 3D-coverage direction.

- **Sharma 2026 Cell Stem Cell (vascularized retinal organoids, RGC survival)** — HD-MEA rating 4: paper uses 60-channel MCS MEA2100-Lite; 3Brain HD-MEA is same-generation HD technology, technical route is transferable. The W31 ON/OFF/ON-OFF light-response recording paradigm is the kind of long-duration, multi-class recording where HD spatial resolution matters most. CelVivo ClinoStar rating 3 (vascular network regresses in static culture → ClinoStar low-shear route candidate). W18 RGC yield **18.2% vs ctrl-RO 1.21% (15× improvement)** through C3 endothelial monolayer integration.

## Cross-vendor workflow links

- **CelVivo + 3Brain joint workflow** (from Raji 2026): hMOs are cultured in a **bioreactor** (CelVivo-class, low-shear rotating-wall) for 12 weeks; transplanted to **3Brain Accura-3D** (4096-electrode HD-MEA chip) for 24h spike-train recording via BrainWave 5. Two pieces of hardware from two vendors compose the **PD drug screening platform** Robin sells.
- **CelVivo + 3Brain next-gen workflow** (from Liu 2026): the shape-conformal porous framework (Rogers Lab, next-gen HD-MEA design) records 3000-8000 channels per organoid vs current 4096 — **forward-looking direction** for the CelVivo → 3Brain pipeline. Track in `/commitments.md` as `liu-2026-hd-mea-roadmap-implication`.
- **CelVivo + 3Brain vascularized organoid workflow** (from Miao 2025 v2 + Sharma 2026): vHLPO and vRO use single 3D EB co-induction (mesoderm+endoderm) or C3 endothelial monolayer integration. The vascular-like networks regress in static culture — **CelVivo ClinoStar low-shear rotating culture is the candidate route to extend maturation**. Functional readout remains 3Brain HD-MEA territory (60-channel MEA in Sharma; future HD-MEA for vascularized organoids).
- **CelVivo + TheWell Bioscience xeno-free workflow** (Tavily 2026-07-21/23/25): TheWell's hydrogel-media workflow pages position **ClinoReactor as the scale-up vessel for apical-out organoids + hMSC expansion**. Tracks in `/commitments.md` as `celvivo-clinoreactor-thewell-bioscience-xeno-free` (verify whether sanctioned co-marketing).
- **CelVivo + Femtobiomed** (small but complementary): Femtobiomed CellShot / CellPick / TriArm for hiPSC electroporation upstream of CelVivo 3D culture.

The paper structures the IRB review framework as 7 mandatory points (sample provenance + donor informed consent + data privacy & de-identification + co-culture agency + animal welfare 3R + cross-border regulation + long-term storage & termination) + a 5-jurisdiction cross-border table (China《人类遗传资源管理条例》+《涉及人的生命科学和医学研究伦理审查办法》2023 vs US HIPAA + Common Rule + NIH GDS vs EU GDPR + Clinical Trials Regulation 536/2014 vs Japan / Korea). 3-commit LDR cycle 2026-08-16 (`2e6f5989` → `00f824f2` → `a4fa5a32`).

## Cross-cutting relationship

- **Vendor-channel evidence flows:** [`/sources/web-search.md`](/sources/web-search.md) is the primary vendor-news surface; Tavily answer text is **untrusted** (mis-attribution is common on this lane — see the consistent MO:BOT mis-attribution as ClinoReactor / 3Brain EEG-headset mis-attribution as CorePlate). Trust URLs + score + published date; treat answer text as low-confidence.
- **Literature deep-read pipeline:** [`/sources/literature.md`](/sources/literature.md) tracks every paper Robin has read. Recent 30-day CelVivo count: 5; 3Brain: 1; adjacent vendors: 2. Most deep reads are routed into [`/themes/05-robin-research.md`](/themes/05-robin-research.md).
- **Daily-driver AI tools touch this theme** through [`/themes/03-ai-agents.md`](/themes/03-ai-agents.md) (literature-deep-read SOP, RAGFlow KB cross-query). The MiniMax-M3 model is what reads CelVivo/3Brain PDFs during the LDR workflow.
