Organoids can be derived from patient-derived normal adult or tumor tissues (patient-derived organoids, PDOs) or pluripotent stem cells, including human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs). Isolation and expansion
Yes. Organoids can be temporarily stored at low temperatures (e.g., 4 ℃) for short-term use, while long-term storage relies on cryopreservation with type-specific optimized cryopreservation media. Most patient-derived organoids can be successfully cr
Organoids can be analyzed by immunocytochemistry (ICC) or immunohistochemistry (IHC) using whole-mount staining or paraffin embedding and sectioning techniques. It is essential to use antibodies that have been validated for organoid-based application
Yes. Within a suitable range, studies (e.g., Calandrini et al., 2022) have shown that the growth rate and size of organoids are positively correlated with the number of cells seeded. Seeding at an appropriate density enhances organoid formation effic
Generally, organoids can be maintained and expanded in vitro for several weeks to years, with tumor-derived organoids capable of near-indefinite passaging. Their longevity is mainly determined by tissue origin, donor health status, stem cell potency,
Organoids can be generated from a wide range of epithelial tissues, including both healthy and diseased intestine, liver, pancreas, breast, and lung, either directly from patient- or animal-derived tissues, or through directed differentiation of plur
One of the major challenges in organoid culture is the current reliance on animal-derived extracellular matrices (ECMs), such as Matrigel®. Synthetic matrices, including hybrid polyethylene glycol (PEG)-based hydrogels or engineered collagen scaffold
Yes. Organoids are highly suitable for studying a broad range of human diseases, including cancer, monogenic genetic disorders, and metabolic diseases. They faithfully recapitulate patient-specific pathological features and tissue architecture, servi
