The present invention relates to a medium composition for preparing a salivary gland organoid. Also, the present invention relates to: a method for preparing a salivary gland organoid, comprising a step of culturing salivary gland-derived cells in the medium composition; and a salivary gland organoid prepared by the preparation method. A medium for preparing a salivary gland organoid, according to the present invention, can promote the proliferation of a salivary gland organoid, maintain the stemness of the salivary gland organoid, and increase engraftment capability. Therefore, the medium can be used to prepare a large amount of salivary gland organoids with excellent quality, and salivary gland organoids prepared using the medium can be used as a preventive or therapeutic agent for salivary gland-related diseases, an alternative to animal experimental models for salivary gland-related diseases, or the like.

The present disclosure relates to compositions, apparatus and methods for generating one or more scaffolds, including: mixing a hydrogel material and/or an extracellular matrix (ECM) protein in an aqueous solvent to generate an aqueous process solution; and cryoelectrospinning the aqueous process solution onto a plurality of conductive probes extending from a conductive surface of a collector plate disposed within a process chamber under conditions sufficient to generate one or more scaffolds configured to mimic a preselected soft tissue decellularized extracellular matrix. Scaffold compositions are also provided having preselected or tuned characteristics.
