- Cell culture models offer the advantage of mechanistic precision: individual pathways can be isolated and measured without the confounding complexity of a whole organism. However, they have limitations for multi-peptide research, since the interaction between different cell types — fibroblasts, endothelial cells, keratinocytes, macrophages — is central to the repair processes these peptides appear to modulate.
- Animal models, particularly rodent excisional wound models, provide a more physiologically relevant context for studying combination effects. The trade-off is reduced mechanistic resolution. Most published combination peptide research has used a combination of both approaches.
