In order to investigate whether plinabulin induces M1 polarization of human TAMs, we FACS sorted CD11b+CD14+ cells from two tumor digests derived from ovarian cancer patients (predominantly of the M2 phenotype, Supplementary Figure 5), and treated them with plinabulin prior to staining with CTV (Figure 6A). The gene discussed is CD14; the disease is ovarian carcinoma.
