SOX10 and hydrops fetalis: Still, markers of murine HF melanocyte lineages have provided at least a starting point for the exploration and identification of melanocyte plasticity in human skin and include markers for melanogenesis/melanin synthesis, (e.g., MITF, DCT/Trp2, Trp1) and melanocyte development, differentiation, and survival (e.g., SOX10, c-KIT, MITF), among others [2,6].
