The present invention provides a method of inhibiting the leakage of a drug encapsulated in liposomes, which comprises satisfying at least two requirements selected from the group consisting of the following three requirements: using at least two lipid bilayers of the liposomes, controlling the average particle size of the liposomes to 120 nm or more, and using lipid having a phase transition temperature higher than in vivo temperature as lipid constituting the liposomes. Also, the present invention provides a liposome preparation which is stable in vivo and satisfies at least two requirements selected from the group consisting of the following three requirements: the number of lipid bilayers of the liposomes is at least two, the liposomes have an average particle size of 120 nm or more, and lipid constituting the liposomes has a phase transition temperature higher than in vivo temperature.

A new type of kidney miniature organoids based on human embryonic stem cells are prepared and tested as forming cysts in vitro or ex vivo. Assays are developed for screening useful candidate molecules towards inhibiting or treating polycystic kidney disease. This provides a new system for modeling polycystic kidney disease.
