Osteosarcoma Cancer and Organoid Models

Osteosarcoma (OS) is a primary bone cancer that often occurs in adolescents and old populations with the features of high heterogeneity, malignant, and high chance of mortality. Osteosarcoma is mesenchymal cells-originated cancer, which differentiates from most epithelial-derived tumors, can metastasize to the lung, and develops strong drug resistance.

Cancer organoids are in vitro models imitating the three-dimensional structure of tumor tissues, retaining the interactions of tumor cells with complex environments, and therefore have become a prevail clinical associated tool for the study of tumor formation and progression and developing effective therapies for treatment.

Various Strategies

With increasing knowledge in organoid production, Creative Biolabs helps explore optimal strategies for the establishment of osteosarcoma cancer organoids.

Type	Description	Features
Single tumor cell-based organoid	Single cells are collected from tissues and colonial expansion to organoid culture.	Uniformed cell culture; Easy to manipulate comparative assays.
Small tissue pieces-based organoid	Minced small fragments are cultured on pre-solidified collagen.	Simplified culturing steps; Avoiding enzyme digestion-induced disturbance of tumor architecture and microenvironment.
Microfluidic system-based organoid	Apply the advanced microfluidic device for tumor culture in a small volume of channels.	Supporting setting various culture conditions; Simulating the important tumor environment of the vasculature

Subtypes of Cancer Organoid Model

Patient tumor tissue-derived organoid model

CAR-T Efficacy Test Assay

The physiological-related cancer organoid models are suitable for preclinical tests of the response of developed CAR-T cells in vitro.

CAR-T cells are incubated with well-characterized cancer organoids.
Co-culture medium is optimized to support the growth of both T cells and organoids.
T cell-specific cytotoxicity against tumor organoids can be detected in various readouts.

Case Study

Develop Osteosarcoma Cancer Organoid Models from Primary OS Tumor and Lung Metastatic OS
Abstract: Patient-derived osteosarcoma cancer organoids are established by culturing in the extracellular matrix, including collagen and basement matrix. The cancer organoids are formed seven days after seeding and support long-term culturing.
