EXPERIMENT INFORMATION

Rat and Quail Ontogenesis (COS 1129-4)
Principal Investigator
Research Area:
Developmental biology
Species Studied
Scientific Name: Coturnix coturnix Species: Quail
Scientific Name: Rattus norvegicus Species: Rat Strain: Wistar

Description
Objectives:

The flight of Cosmos 1129 attempted to provide information with respect to potential effects of space flight on mammalian fertilization, implantation, and embryonic development. The principal objectives of this study were: 1) to determine the capability of a selected mammalian species to undertake reproductive processes, including copulation, fertilization, placentation, and embryogenesis during space flight exposure; 2) to separate potential space flight factors from indirect factors due to stress; and 3) to demonstrate the capability of avian embryos to carry out normal embryogenesis during space flight.
