Project description:We were interested in defining the gene signature of volar skin. Punch biopsies of skin were split into epidermis and dermis after dispase treatment. Epidermis was trypsinized and sorted for alpha 6 integrin positive basal layer keratinocytes We collected RNA from basal layer keratinocytes of soles and backs of feet and submitted for Affymetrix Exon arrays. 2 replicates of each site from distinct human donors were included; total of 4 samples analyzed

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
