The Benefits of Olive Oil for Skin Health: Study on the Effect of Hydroxytyrosol, Tyrosol, and Oleocanthal on Human Fibroblasts González Acedo, Anabel Ramos Torrecillas, Javier Illescas Montes, Rebeca Costela Ruiz, Víctor Javier Ruiz Rodríguez, Concepción Melguizo Rodríguez, Lucía Raquel García Martínez, Olga Extra virgin olive oil Fibroblasts Phenolic compounds Tissue regeneration Wound healing Fibroblasts contribute to maintaining tissue integrity and homeostasis and are a key cell population in wound healing. This cell population can be stimulated by some bioactive compounds such as extra virgin olive oil (EVOO) polyphenols. The aim of this study was to determine the effects of hydroxytyrosol (htyr), tyrosol (tyr), and oleocanthal (ole) phenolic compounds present in EVOO on the proliferation, migration, cell cycle, and antigenic profile of cultured human fibroblasts. CCD-1064Sk human fibroblast cells were treated for 24 h with each polyphenol at doses ranging 10(-5) to 10(-9) M. Cell proliferation was evaluated using the MTT spectrophotometric technique, migration capacity by culture insert assay, and cell cycle and antigenic profile with flow cytometry. Cell proliferation was significantly increased by treatment with all compounds. The highest increases followed treatments with htyr or tyr at doses of 10(-5) or 10(-6) M and with ole at 10(-6) and 10(-7) M, and these compounds and doses were used for assays of antigenic profile, cell cycle, and migration. During the first few hours after treatment, increased fibronectin and a-actin expressions and greater cell migration were observed, with no cell cycle changes. In conclusion, these in vitro results suggest that phenolic compounds in EVOO might contribute to wound healing through action on fibroblasts related to tissue regeneration. 2023-06-15T08:29:04Z 2023-06-15T08:29:04Z 2023-04-25 info:eu-repo/semantics/article González-Acedo, A.; Ramos-Torrecillas, J.; Illescas-Montes, R.; Costela-Ruiz, V.J.; Ruiz, C.; Melguizo-Rodríguez, L.; García-Martínez, O.
