The movie shows two sequences that begin with an unfertilized Arbacia (sea urchin) egg in which the contents have been stratified using the centrifuge polarizing microscope (CPM) developed by S. Inoue...

The movie shows, in real time, the explosive acrosomal reaction of Thyone (sea cucumber) sperm. The field shows several sperm heads (bright contrast) with tails of some in the plane of focus. From the...

This sequence taken with the polarizing microscope in 1967 shows the reversible enhancement of spindle volume and birefringence by heavy water in arrested metaphase oocyte of Pectinaria gouldi (ice cr...

A live developing sea urchin embryo was imaged using differential contrast microscopy to enhance cellular details. Each minute a through focal series (Z-series) of micrographs was acquired to capture...

The movie illustrates two approaches to understanding the 3D structure of complex objects, using the pluteus stage embryo of the sea urchin Arbacia punctulata. The first sequence is a through-focus DI...

The single cell amoeboid phase of the life cycle of the slime mold Dictyostelium discoidium moves over the substrate by generating cytoplasmic outgrowths known as pseudopodia. In this time lapse movie...

The movie shows the behaviour of human erythrocytes suspended in a percoll gradient and exposed to centrifugal force in the centrifuge polarizing microscope developed by S. Inoue. Here, the contrast i...

Preparation of the live ciliate Tetrahymena pyriformis stained with a mitochondria-specific probe (Mitotracker green) and viewed with the CSU-10 confocal microscope. The mitochondria become visible a...

The movie shows several sequences illustrating the generation of 3D data using the CSU-10 confocal microscope to image the auto-fluorescence of acid treated pollen grains of Dandelion. The first seque...

The movie shows several sequences showing changes in birefringence in oocytes of the marine annelid Chaetopteris that had formed meiotic spindles before exposure to centrifugal force in the Centrifuge...
