The use of ectopic volar fibroblasts to modify skin identity III

Project description:The modification of skin identity, such as the conversion of residual limb/stump (non-volar) skin of amputees to pressure-resistant palmoplantar skin to enhance prosthesis use and minimize skin breakdown, has tremendous clinical potential. Recognizing the capacity of fibroblasts to modify keratinocyte differentiation, we hypothesized that volar fibroblast injections might induce ectopic volar characteristics. First, we observed pressure-responsive volar fibroblast resulting in increased limb development after pressure treatment, then we confirmed this in using a bioprinted skin construct, and later in a clinical trial that showed increased volar measures in non-volar skin after volar fibroblast injections. Bulk and single cell RNA seq demonstrate gene ontology categories of cornified envelope, keratinization and morphogenic pathways. Thus, the long-term engraftment of volar fibroblasts creates a platform for the therapeutic development
