Isolation and separation of murine tumor-associated macrophages (TAMs) subpopulations from orthotopic 4T1 breast tumors
Summary: Tumor-associated macrophages (TAMs) are highly heterogenous regarding their intratumoral localization, surface marker expression, and molecular properties.

| Summary: | Summary: Tumor-associated macrophages (TAMs) are highly heterogenous regarding their intratumoral localization, surface marker expression, and molecular properties. This protocol describes the complete procedure for isolation and digestion of murine breast cancer samples and fluorescence-activated cell sorting (FACS) of TAMs from murine orthotopic 4T1 breast tumors. This includes steps to separate PoEMs (podoplanin-expressing macrophages) and non-PoEMs (podoplanin-negative macrophages). Our FACS separation approach could also be used for other tumor types with TAM infiltration.For complete details on the use and execution of this protocol, please refer to Bieniasz-Krzywiec et al. (2019). |
