## Vendor evidence anchors

### CelVivo evidence

- **Whitepaper: "Breaking the Bias" (2026, 16 pp)** — CelVivo's official vendor narrative on brain organoid long-term culture. Key data: ~110 day / 8 mm diameter brain organoid (Univ. Groningen, Trombetta-Lima); sc-RNA-seq 17,738 cells at Day 90 (Univ. Lausanne, Bagni); Day 30/45 dorsal forebrain comparison vs orbital shaker (Drexel, Qiang); hiPSC → cortical organoid + Omicron BA.5 (QIMR Berghofer, Stewart 2022). 4 patents: WO 2021/001472, WO 2021/245117, WO 2022/008292, WO 2022/144461. Full synthesis at [`/sources/literature-celvivo-brain-whitepaper-2026.md`](/sources/literature-celvivo-brain-whitepaper-2026.md).
- **Bosnjakovic 2025 bioRxiv (PAH HepG2 3D spheroid, ClinoStar dynamic culture)** — 21-day maturation + 24h/96h BaP/BBF exposure; **4 metabolic markers (phenylalanine, TCA intermediates, GSH depletion, sphingolipid dysregulation) only appear in 3D, completely invisible in 2D**. Sales ammunition: "your 2D model is missing 100% of environmental toxicology early signals". Synthesis at [`/sources/literature-cel-bosnjakovic-2025-pah-deepread.md`](/sources/literature-cel-bosnjakovic-2025-pah-deepread.md).
- **Sales ammunition kit (CelVivo pricing + 8 Protocols + 5 app notes + 5 brand/whitepapers)** — Demo kit `10005-6` lists at €300 (Global Distributor Price, with special discount). 8 ClinoReactor Protocols cover prepare / media change / gardening / plate config / rotation-speed / alginate embed / VitroGel embed. 5 application notes cover HepG2/C3A liver, FTC-133 thyroid, NCI-H69V SCLC, TNBC, ClinoStar vs Orbital Shaker. Synthesis at [`/sources/sales-ammunition.md`](/sources/sales-ammunition.md).
- **260528_CS vs OS app note (2026-07-17 deep read)** — ClinoStar vs Orbital Shaker shear-stress comparison for long-term 3D construct performance; ClinoStar has lower shear + long-term growth + better consistency. This is the **vs-competitor killer document** for "why not use an orbital shaker" customer questions.
- **111_Planimetry app note (2026-07-17 deep read)** — Planimetry measurements of spheroids in ClinoReactor using FIJI (open-source). Standard answer for "how to quantify spheroids".

### 3Brain evidence

- **Raji 2026 Mol Psychiatry (hMOs + 3Brain HD-MEA, 2026-07-27 deep read)** — WNT-modulated human midbrain organoids + 3Brain BioCAM DupleX + Accura-3D (4096 electrodes) + BrainWave 5. **TH+ 58% at 12 weeks** (vs 2D 18%, 3D static 32%). 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).

- **Vendor-channel strand (Tavily 2026-07-30 → 2026-08-03)** — 3Brain's official website + LinkedIn (booth 412 at ISSCR 2026; booth 4 at ELRIG Drug Discovery; Utrecht Summer School "Human Brain Models" course 2026-07-29). Tracks in `/commitments.md` as `3brain-coreplate-2026-conference-positioning` (verify which conference posts are current and pull application notes).

## 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 + 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.

## Distribution and customer layer

- **Agents (vendor-side technical contacts)** — [`/sources/agents.md`](/sources/agents.md) tracks Robin's actual distributor/agent network. Currently **1 active profile**: 董慧群 (CelVivo ClinoStar/ClinoReactor distributor technical contact; most fields 待补). Open question: see [`/open-questions.md`](/open-questions.md) `agent-dong-huiqun-celvivo` (agency company, region, contact info).
- **Distributor map (261 dealers across 7 regions, 2026-07-24)** — [`/sources/distributors-china-2026.md`](/sources/distributors-china-2026.md). Regional distribution: 华北 74 / 华东 68 / 华南 62 / 山东 25 / 湖北 19 / 西北 6 / 西南 7. Brand keyword map (top brands by region) is preserved. **Sensitive fields (phone/微信/邮箱/终端客户清单/商机金额) are not stored here** — they live in the private Obsidian vault.
- **Active CelVivo commercial docs** — `05-Documents/Products/Celvivo/Industrial-Customers/` (惠百生物 demo discount agreement, 2026-06-21 PO盖章版, 2026 global distributor price book) — see [`/sources/git-repo.md`](/sources/git-repo.md) Notable entities.

## Regulatory and China-specific context

- **China CDE cell & gene therapy classification rules (2026-07-24)** — affects CelVivo-class deals in the Chinese pharma R&D / CDMO customer base. Tracks in [`/commitments.md`](/commitments.md) `china-cde-cell-gene-therapy-rules-2026`.
- **China Order No. 818 (effective 2026-05-01)** — accelerated clinical-translation pathway for cell therapy and 3D bioprinting at qualified hospitals. Tracks as `china-order-no-818-clinical-translation`.
- **China CGT 2026-07 developments** — Merck–Bio-Techne $11.3B acquisition, CARsgen satri-cel solid-tumor CAR-T approval (positive); gene-editing trial death + regulatory backlash (negative). Tracks as `china-cgt-2026-july-developments`.

## 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.
