The presomitic mesoderm in the mouse embryo is developmentally homologous to the caudal paraxial mesoderm of amphibian embryos (Woo Youn ., 1980) and to the segmental plate of avian and reptilian embryos (

This pattern consisted of 10 to 12 tandem circular cellular domains that he termed “somitomeres.” Subsequent collaborative efforts between us demonstrated that somitomeres and prospective somites were one and the same and that these somitomeres became somites through a process of compaction (

Sometimes their morphogenesis is disturbed, by genetic or environ- mental factors, and there are many clinical conditions which arise as a result.

All the work described relates to events in the amphibian embryo, although it is likely that the basic elements of these events will have many points of similarity in all vertebrate species.

It seems therefore that the genetic programming is not precise and may be modified by controlling events in embryonic development.

Our further . study indicates that the chemical composition of matrix surrounding the somite is critical in ECM-induced somite chondrogenesis (Vasan and Miller, 1985).

se the somites - once established - exert a profound influence on other seg- mental structures which form later. Somite development is of interest at a number of levels. In one aspect, demarcation of a specific number of somites and size regulation, it is a particularly intriguing example of embryon
