Cell cycle profiles were analyzed by propidium iodide staining as described in detail elsewhere18 (link). The number of apoptotic cells in the population was estimated by the Annexin-V Alexa488/PI kit (Invitrogen) according to the provider’s recommendations. Maturation status of the differentiating neutrophilic cell population was analyzed by immuno-detection of cell surface markers. The following combination of antibodies were used: PE mouse anti-human CD16b, APC mouse anti-human CD34, APC-Cy7 mouse anti-human CD11b, PE-Cy7 mouse anti-human CD14 (all from BD Biosciences) and FITC-anti-Annexin V (Invitrogen). Neutrophilic differentiation stages were identified by gating on subpopulations according to the expression of surface markers (Supplementary Fig. S6)57 (link): CD34+ cells (CD34+, CD11b−, CD16b−), promyelocytes (CD34−, CD11b−, CD16b−), myelocytes (CD34−, CD11b+, CD16b−) and metamyelocytes (CD36−, CD11b+, CD16b+). Monocytes were identified according to the expression of CD14+. All samples were measured with a FACS cytometer (BD Biosciences) and analyzed by the FlowJo software. Data were statistically analyzed by χ2 test for each replicate as well as pairwise comparison by Student’s t-test in GraphPad Prism. Full methodical details are given in the Supplementary information online.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
