What Are Organoids?
Organoids are three-dimensional (3D) cellular structures grown from stem cells that self-organize into miniature versions of human organs.
Unlike conventional monolayer cultures, organoids preserve:
Cellular diversity
Tissue architecture
Cell-to-cell communication
Functional organization
Biological complexity
Because they closely resemble native tissues, organoids have become valuable experimental models for studying human biology.
Common Types of Organoids
Researchers have successfully developed organoids representing numerous organs, including:
Brain organoids
Liver organoids
Kidney organoids
Lung organoids
Intestinal organoids
Pancreatic organoids
Cardiac organoids
Retinal organoids
Gastric organoids
Skin organoids
Tumor organoids
Each model offers unique opportunities for studying organ development, physiology, and disease mechanisms.
Understanding Organ-on-a-Chip Technology
Organ-on-a-chip technology combines:
Microfluidics
Biomaterials
