Mesenchymal stem cells and collagen patches for anterior cruciate ligament repair

Figure 6 Mitochondrial cell activity. Mitochondrial cell activity measured by resazurin red assay of collagen patches seeded with anterior cruciate ligament-derived tenocytes (TCs) and/or MSC on NC and CG normalized per dry weight carrier for the collagen patches for day 1 and day 7 of the experiment (values are means ± SEM, n = 4 experiments for CG and n = 5 experiments for NC). b denotes P < 0.01. MSC: Mesenchymal stem cell; NC: Novocart™; CG: Chondro-Gide™; SEM: Scanning electron microscope.
