英文摘要 | Human pluripotent stem cell (hpsc)-derived islet cells provide promising resources for diabetes studies, cell replacement treatment and drug screening. recently, hpsc-derived organoids have represented a new class of in vitro organ models for disease modeling and regenerative medicine. however, rebuilding biomimetic human islet organoids from hpscs remains challenging. here, we present a new strategy to engineer human islet organoids derived from human induced pluripotent stem cells (hipscs) using an organ-on-a-chip platform combined with stem cell developmental principles. the microsystem contains a multi-layer microfluidic device that allows controllable aggregation of embryoid bodies (ebs), in situ pancreatic differentiation and generation of heterogeneous islet organoids in parallel under perfused 3d culture in a single device. the generated islet organoids contain heterogeneous islet-specific a and beta-like cells that exhibit favorable growth and cell viability. they also show enhanced expression of pancreatic beta-cell specific genes and proteins (pdx1 and nkx6.1) and increased beta-cell hormone specific ins gene and c-peptide protein expressions under perfused 3d culture conditions compared to static cultures. in addition, the islet organoids exhibit more sensitive glucose-stimulated insulin secretion (gsis) and higher ca2+ flux, indicating the role of biomimetic mechanical flow in promoting endocrine cell differentiation and maturation of islet organoids. this islet-on-a-chip system is robust and amenable to real-time imaging and in situ tracking of islet organoid growth, which may provide a promising platform for organoid engineering, disease modeling, drug testing and regenerative medicine. |
