| Abstract: |
Lysosomes are involved in a myriad of cellular functions, such as degradation of macromolecules, endocytosis and exocytosis, modulation of several signaling pathways, and regulation of cell metabolism. To fulfill these diverse functions, lysosomes can undergo several dynamic changes in their content, size, pH, and location within cells. Here, we studied some of these parameters during embryonic chick skeletal muscle cells. We used an anti‐lysosome‐associated membrane protein 2 (LAMP2) antibody to specifically determine the intracellular localization of lysosomes in these cells. Our data shows that lysosomes are highly enriched in the perinuclear region of chick embryonic muscle cells. We also showed that the wingless signaling pathway (Wnt)/β‐catenin signaling pathway can modulate the location of LAMP2 in chick myogenic cells. Our results highlight the role of lysosomes during muscle differentiation and particularly the presence of a subcellular population of lysosomes that are concentrated in the perinuclear region of muscle cells.
