[Series 8] Moving Images
This series consists of a number of reels of film related to tissue culture and cell biology. The films include a number of time-lapse films of cells in tissue culture by Warren H. Lewis.

162676Growth of capillaries and endothelium from subcutaneous tissue / Warren H. Lewis. — 1936. — 1 film reel (147 ft., 6 min.) : sil., b&w ; 16 mm. release print
Creator: Lewis, Warren H. (Warren Harmon), 1870-1964.
Cultures of subcutaneous tissue from 7-day check embryos in fluid medium show migrating capillaries and endothelial cells, which may form plexuses. Small segments become disconnected and migrate independently among the mesenchyme cells. Somewhat similar events occur during normal embryonic vascularization.

An ovum showing two cells, two polar bodies, and zona with three sperm was washed from the tube about 30 hours after ovulation and fertilization. It was mounted in monkey plasma. Cleavage is dichotomous but not simultaneous. The larger of the first two cells shows at each pole of the nucleus a mass of dark satellite granules, which surround the centrosomes. The nucleus disappears before cleavage, chromosomes are not visible. The movements of the satellite granules indicate when one centrosome moves to the opposite pole of the nucleus in two of the cells of the 4-cell stage.
