For cell growth analysis, the cells were fixed the with 4% paraformaldehyde (Solarbio, P1110) for 15 min at room temperature, then permeated with 0.3% Triton-X (Solarbio, 9002-93-1) for 15 min at room temperature. Next the cells were stained with EdU according to the instruction of
EdU kit (Beyotime, C0071L), and analyzed the percentage of the EdU positive cells by flow cytometer (
BD Canto II). The cell cycles were performed following the instructions of the
cell cycle kit (Beyotime, C1052).
To analyze the differentiation of cell, the cells were incubated with anti-human CD11b, CD15 antibody (BioLegend) at 4 °C for 30 min then washed once with
PBS (Gibco). The proportion of CD11b
+ CD15
+ cells (differentiated myeloid cell) [41 (
link)] was detected by flow cytometer. On the other hand, for morphology analysis, we spined these cells to slide and stained them with Wright-Giemsa dye, then to observe under the microscope (Leica).
Cells apoptosis was tested by
Annexin-V Apoptosis Detection Kit (BD, 559763). Generally, cells were mixed with 100ul binding buffer supplemented with 1ul Annexin-V PE and 1ul 7-AAD incubating at 4 °C for 30 min, then to analyze by the flow cytometer.
ALL results of flow cytometer were analyzed by FlowJo V10.
