somite

so·mite

(sō'mīt),
One of the paired, metamerically arranged cell masses formed in the early embryonic paraxial mesoderm; commencing in the third or early fourth week in the region of the hindbrain, they develop in a caudal direction typically until 42 pairs are formed.

One of the paired, metamerically arranged cell masses formed in the early embryonic paraxial mesoderm; commencing in the third or early fourth week in the region of the hindbrain, they develop in a caudal direction until 42 pairs are formed; their presence is considered evidence that metameric segmentation is a vertebrate characteristic.

With the advent of transgenic chicken technology (Mozdziak et al., 2003; Mozdziak and Petitte, 2004; Chapman et al., 2005; Lee et al., 2004; Lee et al., 2005; Mozdziak et al., 2006) it is now possible to cross-transplant somitic tissue carrying reporter genes to map cell fate in the post-hatch animal following an embryonic manipulation without any problems associated with graft rejection.
The objective of these experiments was to develop somitic cell transplantation techniques within the surrogate eggshell culturing system.
The donor somitic tissue was taken from an eGFP positive chick embryo (Chapman et al., 2005).
The somitic tissue taken from the eGFP-positive donor was transferred to the prepared recipient, and the somitic tissue was carefully placed in the groove left by the somitic tissue excised from the recipient embryo.
