This study investigated the effects of Caragana sinica flower absolute (CSFAb) on skin repair responses, including wound healing and anti-wrinkle effects. The results showed that CSFAb promoted proliferation, migration, and sprouting of keratinocytes, and influenced various signaling pathways and molecular phosphorylation levels. These findings suggest the potential use of CSFAb in skin repair and care preparations.
Caragana sinica (CS; family Legume) was used as a medicinal material to treat neuralgia and arthritis in folk remedies and has been shown to have antioxidant, neuroprotective, and anti-apoptotic effects. However, CS is unknown for its biological activities related to skin. The present study explored the effects of CS flower absolute (CSFAb) on skin repair responses, viz., wound healing and anti-wrinkle-related responses using keratinocytes. CSFAb was extracted using hexane, and its composition was analyzed by GC/MS. The effects of CSFAb on human keratinocytes (HaCaT cells) were evaluated using Boyden chamber, sprouting, water-soluble tetrazolium salt, 5-bromo-2 '-deoxyuridine incorporation, ELISA, zymography, and immunoblotting assays. GC/MS detected 46 components in CSFAb. In addition, in HaCaT cells, CSFAb increased the proliferation, migration, and sprout outgrowth and the phosphorylation of ERK1/2, JNK, p38 MAPK, and AKT, and also increased collagen type I and IV synthesis, reduced TNF-alpha-increased MMP-2 and MMP-9 activities, and upregulated hyaluronic acid (HA) and HA synthase-2 levels. These effects of CSFAb on wound healing and anti-wrinkle-related responses in keratinocytes suggest its potential use for skin repair and care preparations.
