Figure Lengend Snippet: Effect of SCFF on HFDPC and HaCaT cell viability and proliferation. HFDPCs and HaCaT cells were treated with different concentrations of SCFF as indicated for 24 h. ( a ) HFDPC and ( b ) HaCaT viability and proliferation were assessed at various SCFF concentrations (50, 100, 250, 500, 1000, 2500, 5000 μg/mL) using a CCK-8 assay. Values are mean ± SD of three independent experiments. ( a – c ) *** p < 0.001, ** p < 0.01 and * p < 0.05 versus NC group (100%). ( c ) Representative images of cellular proliferation activity in HFDPCs and HaCaT cells after 48 h of incubation ( n = 3; Scale bar = 200 μm). SCFF, Staphylococcus capitis KMH304 ferment filtrate; HFDPCs, human follicle dermal papilla cells; NC, negative control.

Figure Lengend Snippet: Hair growth-related and AGA-inducing signature gene expression following SCFF treatment in HFDPCs. HFDPCs were treated with different SCFF concentrations for 24 h, and gene expression was evaluated using qPCR. ( a ) Hair growth-related factors (KGF, IGF-1, and HGF). ( b ) AGA-inducing factors (AR and TGF-β2). MXD at 5 μg/mL was used as PC for TGF-β2, and 2.5 μg/mL MXD was used as PC for other markers. Data are mean ± SD of three independent experiments. *** p < 0.001, ** p < 0.01 and * p < 0.05 versus NC group (100%). SCFF, Staphylococcus capitis KMH304 ferment filtrate; HFDPCs, human follicle dermal papilla cells; MXD, minoxidil; PC, positive control.

Figure Lengend Snippet: The regulation of cellular senescence by SCFF in HFDPCs. HFDPCs were treated with different concentrations of SCFF for 24 h, followed by analysis using qPCR and SA-β-gal staining. ( a , b ) Anti-aging factors (SIRT1, SIRT7, COL13A1, and p21). ( c ) SA-β-gal staining in young (P6) and senescent (P16) passage cells. Quantitative and representative images of SA-β-gal-positive cells compared with senescent cells (Scale bar = 200 μm). For SIRT, 1 μg/mL fisetin (Fis) was used as a positive control (PC), and for COL13 and p21, 1 μg/mL Fis was used as PC. Data are the mean ± SD of three independent experiments. **** p < 0.0001, *** p < 0.001, ** p < 0.01, and * p < 0.05 versus the negative control (NC) and the senescent group (100%).

Figure Lengend Snippet: Overall effect of SCFF in HFDPCs and HaCaT cells. In keratinocytes, SCFF enhanced barrier function and antioxidant activity. SCFF not only regulated cellular aging through longevity-, collagen-, and p21-related genes, but also promoted hair growth by increasing the expression of hair-growth–associated factors and suppressing hair loss-inducing factors in HFDPCs. SCFF, Staphylococcus capitis KMH304 ferment filtrate; HFDPCs, human follicle dermal papilla cells.

Figure Lengend Snippet: Screening process to determine peptides with hair-restoring properties. ( A ) Human Follicle Dermal Papilla Cell (HFDPCs) viability of over 200 cell-penetrating peptides, with EGF as the positive control. The red dots mark the peptides with the highest cell viability. ( B ) Western Blot results showing the upregulation of β-catenin and p-ERK proteins of 22 chosen peptides compared to the control. Peptide No.218 (in red rectangle) showed the highest expression level of β-catenin and p-ERK proteins, and was chosen for subsequent analyses. ( C ) Cell-penetrating capability of DualPep-ALO was evaluated using FITC-conjugated peptides in HFDPCs. Cells were treated with FITC-DualPep-ALO or FITC-TAT (2.5 µM, 2 h), followed by extensive washing and trypsinization to remove membrane-bound peptides. Intracellular fluorescence intensity was quantified by flow cytometry. Each experiment was performed three times
