Here, a phosphoflow cytometry-based method is described to analyze signaling downstream of the mTORC1, JAK/STAT5, and MAPK pathways in acute human myeloid leukemia cells xenografted into mice and obtained from bone marrow aspirates. p-STAT5, p-4EBP1, p-RPS6, and p-ERK1/2 levels are simultaneously measured using a next-generation spectral flow cytometer with high sensitivity.
