Dividing egg of the jellyfish (Spirocodon saltatrix showing birefringent spindles. The arrow indicates the direction of the compensator slow axis. AS the cell is rotated 90 degrees with respect to the...

The time-lapse movie shows early development in the Lytechinus (sea urchin) embryo. Polarizing microscopy highlights the mitotic spindles which may show bright or dark contrast according to their orie...

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 shows mitosis in a cell of the liquid endosperm of the African Blood Lily Haemanthus katherinae observed with phase contrast. The movie begins at prophase and proceeds through met...

Time lapse movie showing mitosis and cleavage in fertilized eggs of the jellyfish Halistaura cellularia. The use of polarizing microscopy reveals the mitotic spindles, which are seen in bright or dar...

The movie shows the rhythmic movement of the termite flagellate Pyrsonympha, a symbiont that lives in the hindgut. The motile structure is a complex of ~2,000 aligned microtubules, the axostyle which ...

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, ...

Time lapse movie showing several sequences of mitosis in pollen mother cells of the Easter Lily recorded in 1951 on 16 mm film with an early polarizing microscope developed by Shinya Inoue. The work w...

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...

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...
