ABSTRACT
Organoid is one of the hottest areas of research in the field of stem cells, which is an organ in a dish with three-dimensional structure and physiological functions that are highly similar to organs in vivo.At present, the generation methods of lens organoids, namely the lentoid bodies, have been established and continuously developed.The double-convex transparent lentoid bodies, with refractive function and all microscopic components of natural lenses, act as reliable in vitro models of human lenses and provide convenience for studying the mechanism of lens development.Moreover, the establishment of age-related cataract and congenital cataract models based on the lentoid bodies also provides great convenience and reliability for the study of pathological mechanism of cataract and drug screening, showing broad prospects in basic research and even clinical transformation for cataract.
