  • Title: Analysis of Integrin-Dependent Melanoblast Migration During Development.
    Author: Haage A, Tanentzapf G.
    Journal: Methods Mol Biol; 2023; 2608():207-221. PubMed ID: 36653710.
    Abstract:
    The neural crest is a transient embryonic structure that gives rise to a number of important cell types and tissues, including most of the peripheral and enteric nervous systems, pigment-producing skin cells known as melanocytes, and many craniofacial structures. Melanoblasts, the precursors of melanocytes, are derived from the so-called trunk neural crest cells. These cells delaminate and migrate along a dorsolateral pathway to colonize their final destination in the skin, and consequently, defects in melanoblast migration result in pigmentation defects. Studying melanocyte migration is a topic of great interest due to the involvement of melanocytes in highly metastatic skin cancer. A role for integrin-mediated adhesion is well established in neural crest migration, and our recent work has provided direct evidence for a key role for integrin-based adhesion in melanocyte migration. Imaging of melanoblast migration in the context of intact skin has proven to be a particularly powerful tool to study integrin-based adhesion during melanoblast migration. Here, we describe the use of skin explants combined with genetically encoded markers for melanocytes and high-resolution live imaging as a powerful and informative approach to analyze melanoblast migration in an ex vivo context.
