Stereology of the dermo-epithelial interface of the matrix-papilla unit of the hair bulb. Computerized processing of tridimensional images
Van Neste D, et al
Images of the spatial relations of the matrix-papilla unit of the human hair bulb are shown. Hair bulbs were reconstructed in 3 dimensions by a computer graphics system from measurements made on horizontal sections parallel to the scalp surface. …snip… As an end result, the hair bulbs appear as wire frame structures in which the boundaries between consecutive segments have been connected to improve rendering of the dermal papilla interacting with the overlying epithelial hair matrix. This computerized method has been used to evaluate dermal-epithelial stereology of the interacting dermal papilla and epithelial hair matrix in hair bulbs. ..snip.. This method could be useful to demonstrate disturbed dermal-epithelial interactions in other types of alopecia and to evaluate potential biological effects of drugs used in the treatment of hair loss.
