Human Gastric Cancer Organoid Culture Workflow

Generating reliable patient-derived gastric cancer organoids requires a controlled workflow that preserves tumor-derived cells while providing suitable conditions for 3D growth and expansion. XR Human Gastric Cancer Organoid Culture Kit is designed to support the complete workflow from primary gastric tumor tissue processing to gastric cancer organoid establishment and maintenance.

Step 1: Primary Gastric Tumor Tissue Preparation

Fresh human gastric cancer tissue samples are prepared under sterile conditions and processed into small tissue fragments. Proper tissue preparation helps improve subsequent cell recovery and supports successful patient-derived gastric cancer organoid establishment.

Wash tumor tissue samples with sterile PBS to remove unwanted components.
Cut tissue samples into approximately 1–3 mm³ fragments for downstream processing.

Step 2: Tissue Dissociation and Cell Collection

Processed tissue fragments are dissociated into cell populations suitable for organoid culture. After filtration and centrifugation, collected cells are prepared for embedding within extracellular matrix materials.

Tissue digestion performed at 37°C for approximately 15–45 minutes depending on tissue characteristics.
Cell suspension is filtered to remove undigested tissue fragments.
Optional red blood cell removal can be performed when required.

Step 3: Gastric Cancer Organoid Formation

Prepared gastric cancer cells are mixed with extracellular matrix and seeded into culture plates. Following matrix solidification, complete gastric cancer organoid culture medium is added to support three-dimensional tumor organoid formation.

Recommended cell density: 1 × 10⁵ – 1 × 10⁶ cells/mL.
Matrix gel incubation: 37°C for approximately 15–25 minutes.
Culture conditions: 37°C, 5% CO₂.

Step 4: Organoid Expansion and Maintenance

Established human gastric cancer organoids can be maintained and expanded for downstream cancer research applications, including tumor biology studies, drug screening models, and precision oncology research workflows.
