Abstract

Platelet‑derived growth factor‑BB (PDGF‑BB) is a potent mitogenic, angiogenic and chemoattractant, and is one of the most abundant growth factors in platelet‑derived products. The goal of the present study was to examine the effects of PDGF‑BB on cellular morphology and cellular viability using 3D stem cell cultures. On day 1, spheroids formed well in silicon‑elastomer‑based concave microwells. The addition of 10 or 100 ng/ml PDGF‑BB did not affect the morphology of the cell spheroids. During longer periods of incubation, the cell spheroids maintained their shape without noticeable alterations. The majority of cells in the spheroids exhibited green fluorescence when analyzed using a live/dead assay, indicative of live cells. On day 1, the Cell Counting Kit‑8 (CCK‑8) assay values for PDGF‑BB at 0, 10 and 100 ng/ml were 0.241±0.003, 0.227±0.001 and 0.241±0.004, respectively; on day 3, the CCK‑8 assay values for PDGF‑BB were 0.233±0.005, 0.278±0.001 and 0.194±0.003, respectively; and on day 7, they were 0.248±0.014, 0.293±0.031 and 0.346±0.034, respectively. The 100 ng/ml group showed significantly higher values compared with the control group on day 7. Together, the results of the present study showed that the addition of 10 and 100 ng/ml PDGF‑BB increased cellular viability, suggesting that PDGF‑BB may be usable in cell therapy.
