Figure Lengend Snippet: ACKR2 controls the accumulation of macrophages in the mammary gland. (A) Flow cytometry was used to identify the percentage of CD11b + F4/80 + macrophages within the CD45 + population of the mammary gland during development. Gating based on fluorescence minus one (FMO) controls is shown. (B) FACS analysis of wild-type and Ackr2 −/− -deficient glands was carried out at 6, 6.5, 8 and 12 weeks. Results were combined from two independent experiments, n =8-11. (C) Mac2+ cells, indicated by arrowheads, were visualised within the developing mammary gland by immunohistochemistry. Representative 40× bright-field images of Mac2-stained sections from wild-type and Ackr2 −/− glands are shown. (D,E) The number of Mac2+ cells per gland was the average counted from five individual FOV (40×) either (D) around TEBs or (E) from within adipose tissue, from 6 week ( n =3), 6.5 week ( n =5) and 8 week (wild type n =5, KO n =4) glands. Significantly different results are indicated. Error bars represent s.e.m.
Article Snippet: Slides were blocked using a 20% goat serum (Vector Labs) before staining overnight at 4°C with a 1 in 6000 dilution in PBS containing 1% BSA (Sigma) of either primary rat anti-mouse Mac2 antibody (Cedarlane) or the isotype control antibody IgG2a (BD Biosciences).
