Yolk syncytial layer nuclei undergo epiboly and converge dorsally during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

Leukocyte chemotaxis from caudal vein to tailfin wound site. Video made available by Mark Cooper thru The Zebrafish A Living Laboratory.

Human sperm diluted in buffer imaged at room temperature within two hours of ejaculation. Cell at center swims at constant speed.

Morphogenesis of the ventral yolk syncytial layer (YSL) from sphere stage to the end of gastrulation. The last round of nuclear division occurs before marginal band contraction and epiboly begins. As ...

Sixteen cell stage Zebrafish embryo. The first frame shows cells at metaphase. The sequence covers the next four cell cycles. In each prophase, there is a rapid onset of yolk platelet motility. Yolk m...

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 ...

Topographical regulation of keratinocyte migration. 2D, 3D, and 1D fibrillar migration of human epidermal keratinocytes. 2D matrices were constructed by uniform coating with extracellular matrix (ECM)...

Figure 436 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cytoplasm of a Sertoli cell from testis of the ground squirrel, Citellus lateralis in cu...

Video replicating some of the challenges neutrophils are likely to encounter along their way through tissues. Neutrophils are the white blood cells and their main function is to protect us against i...

Off-axis patterns perturb uniaxial migration, while 1D lines promote conversion to fibrillar migration. Effects of encountering a perpendicular fibrillar pattern during fibrillar migration (top) and c...
