In recent y.ars, advances in microfabrication technology.and tissue engineering have propelled the development of a novel drug screening and disease modelling platform known as organoid-on-a-chip. This platform integrates organoids and organ-on-a-chip technologies, emerging as a promising approach for in vitro modelling of human organ phy.iology. Organoid-on-a-chip devices leverage microfluidic sy.tems to simulate the phy.iological microenvironment of specific organs, offering a more dy.amic and flexible setting that can mimic a more comprehensive human biological context. However, the lack of functional vasculature has remained a significant challenge in this technology. Vascularisation is crucial for the long-term culture and in vitro modelling of organoids, holding important implications for drug development and personalised medical approaches. This review provides an overview of research progress in developing vascularised organoid-on-a-chip models, addressing methods for in vitro vascularisation and advancements in vascularised organoids. The aim is to serve as a reference for future endeavors in constructing fully.functional vascularised organoid-on-a-chip platforms. © 2024, Chinese Medical Multimedia Press Co Ltd.

A composite scaffold composed of a porous scaffold and hy.rogel filling can facilitate engraftment, survival, and retention in cell transplantation processes. This study.presents a composite scaffold made of poly.ε-caprolactone) (PCL) and methacry.ated hy.luronic acid (MeHA) hy.rogel and describes the corresponding phy.ical properties (surface area, porosity. and mechanical strength) and host response (angiogenesis and fibrosis) after subcutaneous transplantation. Specifically. we sy.thesise MeHA with different degrees of substitution and fabricate a PCL scaffold with different porosities. Subsequently. we construct a series of PCL/MeHA composite scaffolds by.combining these hy.rogels and scaffolds. In experiments with mice, the scaffold composed of 3% PCL and 10–100 kDa, degree of substitution 70% MeHA results in the least fibrosis and a higher degree of angiogenesis. This study.highlights the potential of PCL/MeHA composite scaffolds for subcutaneous cell transplantation, given their desirable phy.ical properties and host response. © 2024, Chinese Medical Multimedia Press Co Ltd.
