Mouse Mesenchymal Progenitor Cells Expressing Adipogenic and Osteogenic Transcription Factors Suppress the Macrophage Inflammatory Response

Figure 2

The phagocytic index of MΦ is increased when in coculture with aortic mesenchymal progenitor cells, mAo. Fluorescent micrographs of MΦ, mAo/MΦ, and D1/MΦ cultures exposed to 5 and 10 particles of FITC labeled zymosan-A per MΦ cell. Cultures were counterstained with DAPI to delineate nuclei (a). Micrographs were used to quantify MΦ uptake of zymosan particles. Counts per cell are presented in the following ranges: [1–5], [6–10], [11–15], and [16+] zymosan-A particles per cell (b). Data represent findings from 3 experiments, each with an .
