Andrographolide Enhances Proliferation and Prevents Dedifferentiation of Rabbit Articular Chondrocytes: An In Vitro Study

Figure 4

Confocal laser scanning microscopy images showing the viability of chondrocytes. Control, T1, T2, and T3 represent groups with 0 (Control), 1.5 (T1), 3 (T2), and 6 μM (T3) ANDRO, respectively, to be cultured in vitro for 2, 4, and 6 days. Cell seeding density: 2 × 10⁴/mL (original magnification ×100). Scale bar = 200 μm.
