Langerhans' cells were studied in the epidermis of two patients with active Behçet's disease and compared with those in two normal controls. Ultrastructural morphology and the percentage of Langerhans' cells found were similar in patients' (1.88%) and the control epidermis (1.79%). The density of Langerhans' cells in adjacent sites of the same epidermis was not homogeneous, being in the range o...

To determine whether the factor(s) responsible for the conservation of epidermal specificities in adult guinea pigs and hamsters resides in the germinal layer of the epidermis or in the dermis, thin grafts of skin, possessing qualitatively distinct regional characteristics, were separated into their superficial epidermal and dermal components with the aid of trypsin. Dermis of one type was comb...

BACKGROUND Proteomic approaches have identified cancer specific biomarker proteins in the nuclear matrix fraction of cancer cells. We wanted to determine whether a similar approach could be used to investigate melanoma biomarkers. OBJECTIVE Since it was not clear that a nuclear matrix fraction could be isolated from the intact human epidermis, we first wanted to determine whether a nuclear ma...
