Evolution & Reproduction
The core mission of the Driskell Laboratory is to investigate mechanisms that will induce regeneration in skin wounds utilizing fibroblast lineages.
The Story of Scar Formation in Skin and a Way to Achieve Scar-less Wound Repair
Picture:Young skin heals with minimal scarring. This is because young skin has the ability to regenerate hair follicles in the wounds (red arrows in the picture). Understanding how to reverse the effects of aging in older skin will lead to better skin repair.
The story of scar formation in the skin starts with an infliction of a wound, which is essentially a newly created hole in the tissue that becomes filled with many different cell types. This includes migrating blood, mesenchymal cells (fibroblasts), epithelial cells which interact to form new tissue which rebuilds new tissue within the hole. The spatial and temporal interactions during this process is critical for repairing the tissue, which normally results in the formation of a scar. Interestingly, it is possible to modulate the repair process, thereby influencing the quality of repair, by controlling epithelial cells and fibroblasts as they enter the blood clot.
We have recently discovered that, by controlling the nature of a fibroblasts before and after wounding in the skin, we can influence hair regeneration in the wound, which represents an essential part of skin regeneration (Driskell e al. 2013 – Nature). In addition, we found that the reason why scars normally lack hair is because adult skin lacks fibroblast subtypes that support hair follicle development. Furthermore, we have also found why young skin heals better than older skin. This is because the critical cells required for hair follicle neogenesis can be found in normal young (neonatal) dermis of mice or can be induced to replicate by increasing Wnt signalling in the epidermis before wounding (Driskell et al. 2013; Rognoni et al. 2016). Despite these advances, our findings revealed a need to investigate the mechanisms that control the type of hair follicle regeneration in the wound and its ability to function.
