Protocol for building an in vitro model of M2-like tumor-associated macrophages with lactic acid or conditioned medium from Lewis cells

Abstract

Summary: The model of M2-like tumor-associated macrophages (TAMs) is an increasingly attractive model for the study of TAMs. However, the detailed process of M2-like TAMs polarization induced by lactic acid or conditioned medium from Lewis cells (LCM) and the identification of M2-like TAMs is not yet available. In this protocol, we present the detailed methods to induce M2-like TAMs polarization and verify its functionality in order to better carry out related research.For complete details on the use and execution of this protocol, please refer to Fang et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
