Paper Abstract
Vitiligo is a depigmentary disease characterized by melanocyte loss attributed most commonly to autoimmune
mechanisms. Currently vitiligo has a high incidence (1% worldwide) but a poor set of treatment options. Piperine,
a compound found in black pepper, is a potential treatment for the depigmentary skin disease vitiligo, due to its
ability to stimulate mouse epidermal melanocyte proliferation in vitro and in vivo. The present study investigates
the use of multispectral imaging and an image processing technique based on local contrast to quantify the
stimulatory effects of piperine on human melanocyte proliferation in reconstructed epidermis. We demonstrate
the ability of the imaging method to quantify increased pigmentation in response to piperine treatment. The
quantization of melanocyte stimulation by the proposed imaging technique illustrates the potential use of this
technology to quickly assess therapeutic responses of vitiligo tissue culture models to treatment non-invasively.
