In the African Spiny Mouse (Acomys), histology on response to extensive wounding in ear tissue and skin shows complete scar-less regeneration of dermis, epidermis (including hair follicles), elastic cartilage, adipose tissue, abundant angiogenesis and unequivocal presence of muscle and nerve fibres in the regenerated tissue. Similar wounds in Mus, however, do not regenerate and only repair at the borders of the cut by fibrotic scarring.
The ESR will compare both species regarding the role of infiltrating cells and the extracellular matrix (ECM) during regeneration/scarring, characterizing them in the wound bed over time. A comparison of Acomys to Mus will show the differences in a scarring and non-scarring systems. In both animal models, the wound healing in skin wounds and ear punches will be assessed to evaluate if the extracellular matrix of Acomys contains cues which trigger scarless regeneration in species which do not have this capacity. Cross-transplants of decellularised skin from Acomys to Mus and vice versa will evaluate its effect on wound healing.
- Identification of cell types involved in scarless skin regeneration in ear punch and dorsal skin wound model in Acomys compared to Mus.
- Identification of extracellular matrix components in scarless skin regeneration in ear punch and dorsal skin wound models in Acomys compared to Mus.
- Cross-transplantations of Acomys decellularised skin on Mus and vice versa to evaluate regenerative/scarring response.
