Bioengineered Tumor Assembloid Construction and Drug Evaluation

I. Service Overview

Assembloids—organoids created by spatially assembling multiple cell types—enable deeper insights into tissue function and disease mechanisms. A straightforward method to generate assembloids involves mixing diverse cell populations (e.g., tumor cells, stromal cells, immune cells) prior to polymerization. For example, assembloids integrating neurons, astrocytes, and microglia have been used to model neuroinflammation and vascularized brain organoids (Nat. Methods 16, 1169–1175, 2019). In oncology, tumor cell-containing assembloids can simulate tumor metastasis by monitoring invasive behaviors.

The tumor microenvironment (TME)—a complex ecosystem comprising tumor cells, cancer-associated fibroblasts (CAFs), tumor-infiltrating lymphocytes (TILs), and extracellular matrix (ECM)—plays a pivotal role in cancer progression, drug resistance, and metastasis. Traditional models fail to recapitulate the spatial organization of TME, where TILs and tumor cells are often enveloped by multilayered fibroblasts. Assembloids excel at modeling such intricate cellular architectures, offering unprecedented resolution for TME studies and drug testing.
