Abstract
The present invention provides a method for producing regenerated hair follicle primordium that allows production of regenerated hair follicle primordium more easily and in larger amounts compared to conventional production methods. A method for producing regenerated hair follicle primordium comprising a step of obtaining hair follicle primordium by culturing a first population of cells comprising epithelial cells and a second population of cells comprising mesenchymal cells while allowing them to be in contact is provided. The production method of the present invention is characterized in that at least either one of said first population of cells and said second population of cells has formed cell aggregates before said contact, and a culture support is not used when contacting the other population of cells with said cell aggregate.
