- Dermal Fibroblasts
- 5–10 μM
- 2.8× increase in COL1A1 mRNA; 70% increase in proliferation rate
- Integrin α2β1 receptor binding → MAPK/ERK activation → collagen gene transcription
- Gold standard model for collagen synthesis studies. Most reproducible data
- Keratinocytes
- 0.5–5 μM
- 40% faster scratch closure; increased migration without hyperproliferation
- Integrin-mediated cytoskeletal reorganization; increased lamellipodia formation
- Best model for studying wound closure mechanics and epithelial repair
- Endothelial Cells (HUVEC)
- 1–5 μM
- Increased VEGF secretion (1.8×); tube formation in Matrigel assays
- Copper-dependent activation of HIF-1α → VEGF transcription
- Angiogenesis model. Relevant for vascularization in wound healing
- Keloid Fibroblasts
- 5 μM
- 50% reduction in TGF-β1-induced α-SMA expression (myofibroblast marker)
- Downregulation of Smad2/3 phosphorylation in TGF-β pathway
- Critical for understanding anti-fibrotic effects and scar reduction potential
- Neuronal Cells (PC12)
- 1–10 μM
- Increased neurite outgrowth (2.5× vs control); upregulation of NGF receptors
- NGF-independent activation of Trk receptor pathways
- Neurotrophic effects. Less studied but relevant to nerve repair applications
