Abstract
White adipose tissue (WAT) explants culture allows the study of this tissue ex vivo, maintaining its structure and properties. Concurrently, isolating mature adipocytes facilitates research into fat cell metabolism and hormonal regulation. Here, we present a protocol for obtaining, isolating, and processing mature adipocytes, alongside the cultivation of WAT explants from humans and mice. We describe steps for WAT retrieval, culturing of WAT explants, WAT digestion, and adipocytes separation. We then detail procedures for culturing isolated mature adipocytes. For complete details on the use and execution of this protocol, please refer to Villanueva-Carmona et al. (2023).1.
