Abstract

The CD36 antigen is a molecule which is ectopically expressed on epidermal keratinocytes of hypertrophic scars and is a good candidate for a marker for a broad range of skin pathologies. Most marker studies have been performed using immunohistochemical techniques on fixed skin sections. Our aim was to investigate the biochemical features of the CD36 expressed in pathological keratinocytes and to find an in vitro model for the study of the regulation of its expression. Here we show how keratinocytes isolated from hypertrophic scars can be cultivated in vitro and employed as a model for the study of these cells. We demonstrated that the antigenic features of the CD36 expressed on keratinocytes of hypertrophic scars are identical to those described for the CD36 expressed by other cell types. The molecule was expressed on the surface of keratinocytes which were non-adherent in vitro. Adherent and proliferating keratinocytes, as well as normal keratinocytes, were CD36 negative both at the surface and intracellularly. The in vitro proliferating cells from hypertrophic scars, but not the normal keratinocytes, showed intracellular expression of CD36 after long-term culture and cell stratification, suggesting a regulated expression of CD36 in pathological keratinocyte differentiation.
