简介：
Overview
This study describes a phosphoflow cytometry-based method used to analyze the signaling pathways downstream of mTORC1, JAK/STAT5, and MAPK in acute human myeloid leukemia cells. The model system involves xenografting these cells into mice, utilizing samples obtained from bone marrow aspirates. Key signaling molecules including p-STAT5, p-4EBP1, p-RPS6, and p-ERK1/2 are measured with a next-generation spectral flow cytometer that offers high sensitivity.
