Albino melanocytes do not make melanin, but they still generate non-pigmented melanosomes

Image: an immunofluorescence micrograph of an albino mouse melanocyte (melan-c) exprssing a variant of a human early stage melanosome constituent, PMEL. The cell was labeled with antibodies to human PMEL (green) and to a constituent of late stage melanosomes, TYRP1 (red). The nucleus was labeled with DAPI (blue).

Tina Ho , a Ph.D. student in the lab of Dr. Mickey Marks, studies melanocytes, a type of skin cell that synthesize melanin pigments responsible for our skin and hair color and for protection against ultraviolet radiation.
