Individual deep cells migrating by blebbing and lamellipodial activity in a fundulus heteroclitus (killifish) embryo. Video made available thru MarK Cooper and Zebrafish The Living Laboratory.

This video shows the dynamics of the apical cell surface of individual cells of the enveloping layer in a killifish embryo. The fluorescent actin is seen to polymerize and depolymerize in cyclic waves...

Rough endoplasmic reticulum and Golgi in epidermal cells of Fundulus heteroclitus scales. Epidermal cells undergoing advanced stages of scale development have prominent rough endoplasmic reticulum and...

Collagen fibrils in the basal plate of Fundulus heteroclitus scales. The basal plate is made of thick collagen fibrils about 100 nm in diameter, which are organized into a plywood-like structure. Note...

This video shows the apical (outside-facing) side of epithelia cells that form confluent tissues where each cell is tightly glued to its neighbors by circumferential junctions like bands of velcro. T...

Collagen fibrils and mineralization in the external layer of Fundulus heteroclitus scale. The external layer is the second of three layers closest to the dermis of an elasmoid. It is composed of thin ...
