For patients with large, full-thickness burn wounds, sufficient donor sites for autografting are not available, and thus, alternate strategies must be used to close these wounds. Cultured epithelial autografts (CEAs) can aid in closing these wounds but are often associated with slow deposition of basement membrane proteins, leading to blistering and graft loss. Rete ridges and dermal papillae present at the dermal-epidermal junction (DEJ) play a key role in epidermal adhesion and skin homeostasis. Promoting the development of an interdigitated DEJ may enhance basement membrane protein deposition and provide enhanced physical interlock of the epidermis and dermis. To develop a dermal template with stable dermal papillae, an electrospun collagen scaffold was seeded with human dermal fibroblasts. Ridged topographies were patterned into the cell-seeded dermal template using laser ablation, creating wide and shallow (ActiveFX) or narrow and deep (DeepFX) wells. Micropatterned or flat (control) dermal templates were combined with CEAs immediately before grafting to full-thickness excisional wounds on immunodeficient mice. CEAs grafted in conjunction with ridged templates showed rete ridge formation at 2 weeks after grafting and led to increased epidermal thickness, proliferation, and stemness compared to templates with a flat DEJ. As this technology is further developed, the dermal papilla-containing dermal templates may be utilized in combination with CEAs to improve adhesion and clinical function. Impact statement Cultured epithelial autografts (CEAs) serve as an adjunct to conventional split-thickness autograft in patients with very large burns, but they are susceptible to blistering that can reduce engraftment. Blistering results, in part, from relatively slow basement membrane deposition after grafting. This study demonstrates that basement membrane deposition and rete ridge formation are enhanced by combination of CEAs with a micropatterned, cell-seeded dermal template. These findings may lead to improved treatment and increased survival in patients with very large burns.
