Abstract
Methods for determining the sensitizing, irritant and/or allergenic potential of a candidate substrate are provided. These methods involve simultaneously cultivating keratinocytes and Langerhans cell precursors in a nutrient medium in order to effect differentiation of the Langerhans cell precursors, and contacting the candidate substrate with the cultured cells to determine the effect if any on markers associated with sensitizing, irritant or allergenic potential.
