Organoids or artificial organs are three-dimensional structures that mimic the architecture and functions of various organs. They are grown in vitro from stem cells or other precursor cells and are used for drug screening and disease modeling, as well as for the development and behavior of different organs.

Organoids are highly valuable for their complex microenvironments and ability to recapitulate the functions of different organs; this makes them valuable tools for studying disease mechanisms and testing potential treatments. Organoid research basically involves three basic aspects: structural strategies, data analysis, and efficacy validation. Among these, structural strategies are crucial for the success of the organoid structure.

Their structural strategy covers three aspects: selection of matrix material (elastic modulus, porosity, degradability, etc.), investigation of cell culture conditions (temperature, humidity, etc.) and screening of various growth factors (WNTs, BMPs, etc.). The construction of organoids or artificial organs involves multiple materials, external stimuli, factors, and their interactions. Research and development activities include the discovery and production of organoids or artificial organs
