Chondrogenic differentiation of DPSCs and quantification of toluidine blue intensity. Chondrogenic differentiation was induced in DPSCs with and without treatment with telomerase inhibitor and DPSCs treated with taurine alone were assessed for chondrogenesis. Functional staining was done with (A–D) toluidine blue, (E–H) Alcian blue, and (I–L) safranin O. Scale bar = 100 μm, (M) Comparative quantification of toluidine blue intensity day 21. * p < 0.05, ** p < 0.01. Induction: Chondrogenic differentiation, Tau: Taurine, TI-III: Telomerase Inhibitor III, TB: Toluidine blue.
