Human dental pulp stem cells (DPSC) were obtained from Lonza (PT-5025). The stemness of human dental pulp stem cells (DPSCs) (p. 16) was confirmed by flow cytometry as previously described [30 (link)]. The expression of positive (CD105) and negative (CD33) markers of mesenchymal stem cells was analyzed, using a BD FACS Canto II flow cytometer (BD Biosciences, San Jose, CA, USA). Briefly, cells were stained with PE anti-human CD105 antibody (323205, Biolegend, San Diego, CA, USA) and APC anti-human CD33 antibody (303407, Biolegend, San Diego, CA, USA), following the manufacturer’s instructions.
