A Dozen Eggs: Time-Lapse Microscopy of Normal Development

Producer: Carolina Biological Supply Company

Sponsored by the Society for Developmental Biology, these research sequences use a wide variety of techniques for embryo preparation, optics, filming, and time compression. They range from a classic film made in the 1940s to sequences obtained using computer-enhanced video microscopy and digital image processing. The 12 organisms covered include many well-studied model systems as well as some less familiar ones: Sea urchin development (4.56 mins.); Slime mould morphogenesis (5.46 mins.); Snail polar lobe formation (2.47 mins.); Meiotic blebbing in flatworms (1.20 mins.); Nematode development (3.40 mins.); Fruit fly embryogenesis (5.56 mins.); Ascidian embryogenesis (2.35 mins.); Frog gastrulation (1.58 mins.); Zebrafish development (2.41 mins.); Killifish deep cell migration (2.48 mins.); Chicken organogenesis (1.57 mins.); Mouse development to blastocyst (2.05 and 1.48 mins.). The teacher’s manual provides descriptions of embryo preparation, as well as diagrams for orientation. In addition, a list of references for each sequence provides more information on normal development of that organism, techniques for manipulating and filming the embryos, and the research program of the filmer.
