The video shows epidermal cells at the edge of an epithelial sheet in culture. There is vigorous lamellipodial activity at the edge of the cell cluster. Lysosomes and elongated mitochondrial are seen near the nucleus. This lamellipodial activity is involved in wound closure; in culture the edge of the epithelial sheet is in a chronic wound state. Video made available by Mark Cooper thru Zebrafish - The Living Laboratory.
