The time lapse movie shows several sequences of mitosis in the liquid endosperm of the African Blood Lily Haemanthus katherinae imaged by polarizing microscopy. Birefringent microtubules are attached ...

The time lapse movie spans fertilization, ooplasmic segregation, and early divisions in the egg of the tunicate Phalusia mammilata. Contrast is provided by both polarizing microscopy and differential...

This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

The time lapse movie shows the rocking motion of the spindle that appears to play a role in the unequal cleavage divisions in a fertilized Spisula solidissima (Clam) egg. Eventually, this leads to t...

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...

Dividing eggs of the medusa Clypeaster japonicus showing birefringent spindles and fertilization envelopes. The arrow indicates the direction of the compensator slow axis. As the direction of compensa...

This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

The movie shows the effect of pressure on the spindle of the Chaetopteris egg. 100 Atm. of pressure induces depolymerization of spindle microtubules leading to the loss of birefringence in this polari...

The series of three vertical columns shows various aspects of mitotic anaphase in a live Barbulanympha (protist). The left column shows the birefringent spindle imaged by polarization microscopy; the...
