Isolation and in vitro cultivation of adrenal cells from mice.

The adrenal gland consists of two tissues, cortex and medulla, united under one capsule. Adrenal stem/progenitor cells play a key role in development and homeostasis. Here, we describe a protocol for generating primary cultures of adrenal cells from mice. We describe techniques for separating the cortex and medulla, generating spheroid cultures containing stem- and progenitor cells, and for the differentiation into steroidogenic and chromaffin cells, respectively. This protocol enables analysis of various treatments before, during, or after differentiation. For complete details on the use and execution of this protocol, please refer to Rubin de Celis et al. (2015), Steenblock et al. (2018), and Werdermann et al. (2021).
