Expression of cre recombinase in pigment cells

open access: yes, 2002
Conditional gene targeting using the Cre/loxP system enables specific deletion of a gene in a tissue of interest. For application of Cre-mediated recombination in pigment cells, Cre expression has to be targeted to pigment cells in transgenic mice.
