(B) hVSMCs were with treated as in A for 48 hours, then qPCR was performed to determine the expression of macrophage differentiation factor Klf4 . (C) hVSMCs were treated with Chol (5 μg/mL) for the indicated times, then KFL4 expression was determined by Western blotting. (D) Klf4 (60 nmol/L) or negative CT small, interfering RNA (siRNA) were transfected into hVSMCs for 48 hours. Then, transfected cells were treated as in B, followed by Western blotting for CD68 and KLF4. GAPDH was used as loading CT. (E) Chol-loaded cells (48 hours, 5 μg/mL) were incubated with Mir145 mimic (60 nmol/L) or CT mimic (60 nmol/LM) for 24 hours and the expressions of CD68, KLF4, and α-SMA determined with GAPDH as a loading CT. The P values for the comparisons between CT and Mir145 mimics are CD68 (0.025), KLF4 (0.018), and α-SMA (0.01).

HDL Increases the Expression of Acta2 Relative to That of CD68 in Atherosclerotic Mice (A) Schematic representation of experimental design. Note that ApoA1, which forms HDL particles in vivo, was injected after atherosclerosis progression (P) to induce regression (R). (B) Representative images from P and R mice that were sufficient ( Tgfβr2 +/+ ) or haplosufficient ( Tgfβr2 +/− ) for TGFβR2, showing the lineage-positive VSMCs (GFP + ) expressing macrophage marker or CD68 (red). Yellow color represents GFP-expressing CD68 + cells. (C) Quantification of GFP + /CD68 + . (D) Aortic digestion followed by cell sorting of GFP + cells was performed using flow cytometry to capture lineage-positive cells (GFP) expressing macrophage markers (CD11b and F4/80). (E) Total RNA was isolated from sorted cells and qPCR was performed to identify Acta2 expression. For data analysis of 2 or more independent groups, 2-way analysis of variance followed by Šídák multiple comparisons post hoc test was performed. Data are presented as the mean ± SEM (n = 5-6 mice per group). P values are as indicated (∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001, ∗∗∗∗ P < 0.0001). DAPI = 4ʹ,6-diamidino-2-phenylindole; other abbreviations as in , , and .

( A ) Representative immunohistochemistry staining showing clear CD68 expression in the monocyte-containing hydrogels (right). Black arrows indicate a “surrounding layer” formed by the CD68 + cells covering the fibroblasts. ( B ) Flow cytometry analyses showing the percentage of total macrophages (CD45 + CD68 + ) isolated from the hydrogels after enzymatic digestion and subsequently CD45 + magnetic selection. Cells (CD45 + CD68 + ) were classified into M1-like (CD163 − ) or M2-like (CD163 + ) macrophages. Comparisons were performed using Student’s t-test (*p<0.05). Each shape represents the average of 3 technical replicates of 1 PBMC donor, n = 3.

Graphs depicting the density of macrophage subsets pre- and posttreatment with TRK-950. Tumor specimens obtained with core-needle biopsies at the screening and C1D22 time points were subjected to multi-immunofluorescence to detect macrophage infiltrates. Quantitative analyses were performed on digital images of CD68 and CD163 staining. A, total CD68 + cells; ( B ) CD68 + /CD163 − subsets; ( C ) CD68 + /CD163 + subsets. Error bars indicate SD.
