What are organoids?
Organoids are 3D structures derived from stem cells that mimic the architecture and function of real organs.
How does the extracellular matrix influence organoid development?
The ECM provides structural and biochemical support that guides cell fate and behavior during organoid formation.
What is the significance of using xeno-free hydrogels?
Xeno-free hydrogels reduce the risk of contamination and immune response, making them safer for human applications.
What challenges exist in drug discovery using organoids?
Challenges include enhancing physiological fidelity, minimizing variability, and establishing standardized protocols.
How can microfluidics improve drug testing?
Microfluidics allows for precise control of the environment and conditions, enabling better simulation of drug interactions.
