This study aims to evaluate and compare the effect of fibroblastic growth factor 2 (FGF-2) and photobiomodulation, solely or in combination, in angiogenic differentiation of human periodontal ligament stem cells (hPDLSCs). The study comprises the following groups: control group (hPDLSCs only), FGF-2 (50 ng/mL) group, two photobiomodulation groups with a 4 J/cm energy density of 808 nm diode laser (1-Session or 2-Session), and two groups with the combination of each 1-Session or 2-Session photobiomodulation with FGF-2 (50 ng/mL). The 4',6-diamidino-2-phenylindole (DAPI) staining, and Methyl Thiazolyl Tetrazolium (MTT) assay were undertaken on days 2, 4, and 6. Quantitative Real-time Polymerase Chain Reaction (RT-qPCR) analysis on days 2, 4, 6, 8, and 11 was conducted to investigate VEGF-A and ANG-I genes. Coherently, the results of the DAPI and MTT showed the Laser (2-Session) group had higher cell viability than others on day 6. All groups demonstrated a growth pattern in the expression of VEGF-A and ANG-I from day 2 to 8 and, afterward, a significant downgrowth to day 11 (p
