Brief Summary

  1. 1.Assess validity of methods involved in molecular studies of the skin in inflammatory skin disease
  2. 2.Assess feasibility of methods for grafting fresh human skin (normal and diseased with inflammatory skin disease) onto an established xenograft murine model.

Outcome Measures

Primary Outcomes (3)

  • Comparative analysis of proteomes on fresh versus formalin-fixed-paraffin-embedded tissue.

    Identification and quantification of proteins as obtained by liquid chromatography-mass spectrometry methods using fresh and formalin-fixed-paraffin-embedded tissue. Mass spectrometry data will be matched against a composite protein sequence database using the MyriMatch search engine and IDPicker will filter protein identification at 2% false discovery rate. QuasiTel software will process the spectral count data for the identification of differentially expressed proteins.

    8 months

  • Viability of human inflammatory skin (lichen planus) graft in a xenograft murine model

    Viability of diseased human graft into an established murine xenograft model by visual inspection and microscopic analysis.

    8 months

  • Evaluation of inflammation around human inflammatory skin graft (lichen planus) and elsewhere in a established xenograft murine model

    Assessment of inflammation around graft and elsewhere in the host by visual inspection and microscopic analysis.

    8 months
