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.
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.
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.
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

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.

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.

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 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 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 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.
Daily-driver AI tools touch this theme through /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.
