This Supplement to Annales d'Embryologie et de Morphogenese contains 

 the main reports and other contributions presented at the 6th International 

 Embryological Congress held in Paris in September 1968. The central theme 

 of the Congress was "Nucleo-cytoplasmic interactions during differentiation". 



Most of the reports are essentially surveys of work already published else- 

 where. They are therefore well suited for reference purposes and for rapid 

 orientation in specific areas. The reports are grouped in five sections as 

 follows: 1. Nucleic acids in embryonic differentiation (7 papers); 2. Nuclear 

 transplantation and differentiation (4); 3. Activities of polytene and lamp- 

 brush chromosomes (3); 4. Nucleo-cytoplasmic relations in the Protista (2); 

 and 5. Chromosomal aberrations and differentiation in Vertebrates (3). Most 

 reports are followed by brief discussions. 



The reports are followed by summaries of three round-table discussions, 

 respectively on the control of micro-molecular synthesis during embryogenesis, 

 on nuclear control of regeneration, and on cytochemical aspects of cartilage 

 formation. The latter two take the form of a series of abstracts and brief 

 reports. The book is concluded by the abstracts of the 56 free communications 

 presented at the meetings, which cover a very broad range of subjects.

This book contains the 11 papers read at the 28th Symposium of the 

 Society for Developmental Biology held in Boulder, Colorado in June 1969. 

 The papers review and describe work carried out on a variety of organisms: 

 bacteria, algal eggs, higher plants, insects, amphibian eggs, and mammals. 



The papers are arranged in five sections, the first of which contains two 

 theoretical papers, one on the concept of molecular messengers, and one on 

 the evolution of developmental communication systems. Section two deals with 

 intracellular communication (in bacteria, in amphibian eggs, and in Fucus 

 eggs). Intercellular communication is discussed in section three (antibody 

 synthesis). The next section deals with communication between the cell and 

 the organism (insect endocrinology, estrogen-receptor interaction in the uterus, 

 auxin and cell enlargement). Finally section five discusses environmental
