The occurrence of gastrulation is universal among animals undergoing embryonic development from eggs, but there is considerable diversity in the types of movement observed. Gastrulation is also the stage at which the first very important developmental commitments are established, in particular those corresponding to the classical 'germ layers'. From an evolutionary point of view, animal development falls into three phases of which the first and last are variable and the middle, phylotypic, phase is most conservative. Gastrulation belongs to the early phase of development which is inherently variable because it is subject to selective forces operating on reproductive behaviour and life history, principally those controlling the number and size of eggs, and the means for embryonic nutrition.</p></div>","PeriodicalId":101155,"journal":{"name":"Seminars in Developmental Biology","volume":"5 2","pages":"Pages 69-76"},"PeriodicalIF":0.0,"publicationDate":"1994-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1006/sedb.1994.1010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73582772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanisms underlying the initial invagination of the archenteron have been surprisingly elusive; several possible mechanisms are discussed. In contrast to its initial invagination, the cellular basis for the elongation of the archenteron is better understood: both autonomous epithelial cell rearrangement and further rearrangement driven by secondary mesenchyme cells appear to be involved. Experiments indicate that patterning of freely migrating primary mesenchyme cells and secondary mesenchyme cells residing in the tip of the archenteron relies to a large extent on information resident in the ectoderm. Interactions between cells in the early embryo and later cell-cell interactions are both required for the establishment of ectodermal pattern information. Surprisingly, in the case of the oral ectoderm the fixation of pattern information does not occur until immediately prior to gastrulation.</p></div>","PeriodicalId":101155,"journal":{"name":"Seminars in Developmental Biology","volume":"5 2","pages":"Pages 77-84"},"PeriodicalIF":0.0,"publicationDate":"1994-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1006/sedb.1994.1011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78123025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
