Communications from the Hubrecht Laboratory 



I The team work project 



Contrary to the information given in the supplement to the seventh issue, the 

 fourth international team work will be held in 1960. However, owing to the 

 rapid extension of the staff of the laboratory the accomodation in the present 

 building does not allow the organization of a "normal" team, so that the fourth 

 team will consist of a limited number of invited members only. Among these 

 there will be several scientists whose applications for previous teams could 

 not be realized. 



Only a very provisional list of participants can be given at the present time: 

 Dr. R. Azoubel, Recife, Brazil 

 Mr. V. Labordus, Utrecht, Holland 

 Dr. M. Michael, Alexandria, Egypt 

 Dr. K. Rzehak, Krakow, Poland 

 Dr. G. Szekely, Pecs, Hungary 



The team work will be held from January 1st till July 31st under the 

 personal direction of Dr. P. D. Nieuwkoop and with the assistance of the 

 other members of the staff. 



The general topic will be: "Experimental studies of basic mechanisms acting 

 in successive phases of vertebrate morphogenesis". It is hoped that the fourth 

 team work will be the last one held in the old building, and that it will be 

 possible to receive the fifth team in the new building, which may be ready 

 in 1962 or 1963. The more or less firmly established tradition of the orga- 

 nization of an international team work evecy second year will in this way be 

 interfered with as little as possible. 



II The building project 



The present building not only offers insufficient accommodation for the 

 rapidly expanding staff of the institute and for the increasing number of foreign 

 workers, but it also greatly restricts the development of the research pro- 

 gramme itself. Embryology is a science which develops very rapidly; many 

 new methods have been introduced in the last decade, leading to new forms 

 of approach and to new subfields of science. 



The new building will therefore provide accommodation for several new 

 fields of research. Besides descriptive and comparative embryology and the 

 already well established field of experimental morphology, which together form 

 the trunk upon which the new branches can be grafted, histo- and cytochemical 

 analysis of development, the method of tissue culture, developmental genetics, 

 developmental physiology and biophysical analysis of developmental processes 

 will receive adequate accommodation, while an additional research unit will 

 be reserved for new, still unknown offshoots. 



This programme will lead to a considerable extension of the scientific staff 

 and consequently of the technical staff as well. 



First of all tissue culture research will be developed by Mrs. H. Sobel from 

 Jerusalem. With this a beginning will be made while still in the old building. 

 In the coming years the other units will be developed one after the other.
