a. Keratinocytes acquire melanin precursors (e.g., tyrosine) from melanocytes via plasma membrane amino acid transporter proteins b. Keratinocytes phagocytize cytoplasmic processes of melanocytes that contain melanosomes c. mRNA molecules that code for melanin proteins are exported from melanocytes to keratinocytes d.
