IFN-γ induces immune characteristics in MKs. (A) The frequencies of MKs in the total BM after IFN-γ injection. (B) The frequencies of IA-IE⁺ MKs after IFN-γ injection. (C) Frequencies and absolute numbers of the ploidy of MKs in normal mice and IFN-γ–injected mice. (D) Frequencies and absolute numbers of the ploidy of IA-IE⁺ MKs in normal mice and IFN-γ–injected mice. Representative flow cytometry plots and results are shown, n = 10 mice for each group. NC, normal MKs; IFN-γ, MKs from IFN-γ–injected mice. ∗∗P < .01. SSC-A, side scatter area.
