Article Abstract

is a naturally occurring plant in East Asia belonging to the Thymelaeaceae family. While its biological properties have been explored, its potential role in wound healing remains largely unknown. This study investigated the effects of extracts on keratinocyte migration and the underlying mechanisms. The crude extract and its fractions was tested in vitro at various concentrations to evaluate their ability to promote keratinocyte migration, and a cytotoxicity assay was conducted to assess cell viability. The results demonstrated that significantly enhanced keratinocyte migration without inducing notable cytotoxicity at tested concentrations. Mechanistically, this effect was mediated through the modulation of matrix metalloproteinase-9 (MMP-9) via extracellular signal-regulated kinase (ERK) signaling, which plays a crucial role in keratinocyte migration. These findings suggest that may serve as a potential therapeutic agent for enhancing keratinocyte migration in wound healing. However, further investigations, including clinical studies, are necessary to confirm its efficacy and safety. To our knowledge, this is the first study to report the potential of in promoting keratinocyte migration, offering new insights into wound healing therapies.

Ethnopharmacological Relevance: Ocimum gratissimum L. commonly known as basil, is an herb-like plant frequently mentioned in ethnopharmacological studies due to its widespread availability in local communities and its widespread use in treating inflammatory conditions. In a previous study, we demonstrated that aqueous extracts of Ocimum gratissimum (OGE), which are rich in plant polyphenols such as caffeic acid and isoflavones, can protect skin cells from UVC-induced inflammation and damage in migration and proliferation.

Introduction: Exosomes produced by mesenchymal stem cells (MSCs) have lately garnered significant attention for their capacity to enhance wound healing. Recent studies have recognized exosomes as significant secretory products from several cell types, specifically MSCs, in regulating multiple biological processes, including wound healing. This work aims to investigate the impact of exosomes derived from the bone marrow mesenchymal stem cells (BMMSCs) of NMRI animals on keratinocyte function.

Background: Atopic dermatitis (AD) and ulcerative colitis (UC) are increasingly prevalent, and growing evidence suggests a potential link between them. However, the shared pathogenesis remains unclear. This study aims to identify the hub genes and immunological features underlying the connection between AD and UC.

Epithelial tissues are populated with accessory cells such as immune cells, sensory cells, and pigment-producing melanocytes, which must migrate through and intercalate between tightly adherent epithelial cells. Although much is known about how cells migrate through interstitial spaces consisting of predominantly of collagen-rich ECM and mesenchyme, how cells migrate through confined epithelial spaces without impairing barrier function is far less understood. Here, using live imaging of the mouse epidermis, we captured the migration of embryonic melanocytes (melanoblasts) while simultaneously visualizing the basement membrane or epithelial surfaces.
