Results from the frog embryology experiment: development of swimming tadpoles occurs at microgravity.

Black S, Larkin K, Souza K.

Ovulation was induced in four frogs during the September, 1992 flight of the Space Shuttle Endeavour. Eggs were fertilized at microgravity and incubated either on the 1g centrifuge or at microgravity. Gastrulae developed at microgravity had a thicker blastocoel roof and formed the blastopore lip nearer the vegetal pole than the 1g sample. Despite these differences, neurulation and subsequent morphogenesis were essentially normal. Living tadpoles returned from the flight differed in some swimming behaviors, but these differences disappeared after one week. Tadpoles from both groups have now completed metamorphosis.
