Intercellular bridges of chick blastoderm studied by scanning and transmission electron microscopy

Chick blastoderms were studied by scanning and transmission electron microscopy to identify by both methods a type of thread-like structure lying on the epiblast. The structure was identified by transmission microscopy as a long telophase bridge containing mid-body and spindle remnant. It appears to provide cytoplasmic continuity between only 2 cells.
