<P>PROBLEM TO BE SOLVED: To provide a fertilized egg culture device for arraying fertilized eggs and successfully retaining the arrayed fertilized eggs, and to provide and a fertilized egg culture apparatus and a fertilized egg culture method using the device. <P>SOLUTION: The fertilized egg culture device includes a micro channel structure where a mammalian fertilized egg and a culture solution are distributed. The micro channel structure includes: a main channel; and a meandering channel sequentially crossing the main channel. The main channel includes a narrowed part having a width small enough not to allow the fertilized egg to pass therethrough. An area between the narrowed part and the meandering channel crossing the main channel upstream thereof serves as a cage area for capturing the fertilized egg. The sidewall of the meandering channel on a downstream side is cut open so that the cage area is expanded toward the downstream of the meandering channel. Moreover, the cage area is provided at the bottom surface thereof with a recessed part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
