organoid

Syllable breakdown

Dictionary meaning

a miniaturised and simplified three-dimensional organ grown in vitro from stem cells that self-organises into structures recapitulating the architecture and cellular diversity of a real organ; organoids can be derived from adult tissue stem cells or induced pluripotent stem cells (iPSCs) and have been established for brain, intestine, kidney, liver, lung, pancreas, and many other organs; they serve as powerful models for studying organ development, disease mechanisms, and drug responses in a context that more closely resembles in vivo biology than traditional two-dimensional cell culture; patient-derived organoids enable personalised drug testing, allowing clinicians to screen drug sensitivity in a patient's own tumour tissue before committing to a treatment regimen; ethical debates surround brain organoids and their potential development of consciousness-like properties
