Longevity & AgingOrganoids Help Researchers Reconstruct Cellular Aging in the Lab
Studying aging cells in a flat laboratory dish leaves out many features of real tissue. This review explores organoids, miniature tissue models grown from stem cells, as tools for understanding how cells permanently stop dividing and affect their surroundings. These models reproduce some tissue organization, cell variety, and biological functions, helping researchers investigate diseases associated with aging and explore potential treatments. The authors discuss how organoids are made, how aging changes are triggered and measured, and how the models could support drug testing and tissue repair research. Better blood vessel networks, immune cells, and connections between organ models could make them more realistic. However, organoids cannot reproduce aging throughout the human body. Based on the abstract alone, this review offers a research roadmap, not evidence that any treatment extends human life.
