A Biomimetic Polynucleotides–Hyaluronic Acid Hydrogel Promotes Wound Healing in a Primary Gingival Fibroblast Model

Polynucleotides (PN) have long been known as an effective supportive therapy for wound healing. The present study investigated whether a hydrogel formulation containing PN and hyaluronic acid (PN + HA) could promote wound healing in an in vitro model of gingival fibroblasts. PN promoted cell growth...

description Polynucleotides (PN) have long been known as an effective supportive therapy for wound healing. The present study investigated whether a hydrogel formulation containing PN and hyaluronic acid (PN + HA) could promote wound healing in an in vitro model of gingival fibroblasts. PN promoted cell growth and viability as assessed by different assays, and PN + HA, though not significantly further increasing cell growth as compared to PN, supported the formation of dense multilayered cell nodules. PN promoted fibroblasts’ clonogenic efficiency and PN + HA further enhanced the formation of more numerous dense colonies. PN + HA appeared to significantly increase the expression of collagen 1a1 and 3a1, while not affecting proteoglycans deposition. Interestingly, when tested in a scratch assay, PN + HA achieved gap closure after 48 h, while cells in the comparison groups had not completely bridged the scratch even after 96 h. Taken together, these results demonstrate that PN + HA is a promising candidate for a supportive therapy to promote soft tissue healing in the oral cavity.
