Lamtor1 is essential for ADM scaffold induction of M2 polarization in vivo. (A) qRT-PCR for Lamtor1 mRNA confirmed successful knock-down of Lamtor1 mRNA in macrophages. (B) In vitro flow cytometric analysis of Lamtor1-deficient macrophages treated with A-ADM or Collagen (1 mg/ml) concurrently stimulated by 50 ng/ml IL4 (n = 4 from two experiment). CD206 = type-2 alternative macrophage. (C) Summary data for fraction of CD206+ macrophages. (D,E) M2 signature genes expression (qRT-PCR) of Relmα (D) and Arg1 (E) displayed as a fold change over control at 48 h after Lamtor1-deficient macrophages treated with A-ADM and Collagen (n = 4 from two experiments). Student's t-test (A,C–E): *P < 0.05, **P < 0.01, ***P < 0.001.
