A drug containing, as an active ingredient, a compound having an antagonistic activity against an EP.sub.2 receptor in the prevention and/or treatment of a disease associated with the activation of an EP.sub.2 receptor, of formula (I-A):

##STR00001##

wherein all symbols have the same meanings as those described in the specification, or a pharmaceutically acceptable salt thereof.

The purpose of the present invention is to provide a novel medical application using pluripotent stem cells in regenerative medicine. The present invention provides a cell formulation and pharmaceutical composition that are for amelioration and therapy for frequent urination and bladder pain caused by the inflammation of the bladder and that contain SSEA-3 positive pluripotent stem cells isolated from cultured mesenchymal cells or a mesenchymal tissue of a living organism. The cell formulation according to the present invention is considered to be based on a mechanism in which, for example, Muse cells are administered against interstitial cystitis having the abovementioned disorders to be successfully engrafted into affected bladder tissue, whereby the disorders are ameliorated and treated.
