Communications from the Hubreclit Laboratory 



I The scientific staff 



The composition of the scientific staff is given in the information booklet 

 distributed in 1966. In addition, a ninth member has joined the staff in 1967: 

 Mr. P. Th. M. van der Saag, M.Sc, a biochemically trained biologist, who 

 is in charge of the unit of developmental biochemistry. In 1968 the staff will 

 probably be extended by a tenth member, who will take charge of the Central 

 Embryological Library and of other work relative to scientific documentation. 



II The international team project 



As was announced earlier the sixth international team in embryology will 

 meet from February 1st till July 31st, 1968. Its central topic will be: "Cell contacts 

 and their role in morphogenesis and cyto-differentiation". The team will work 

 under the guidance of the Director of the Laboratory with the assistance of 

 the scientific staff. Prof. L. Weiss, of the Roswell Park Memorial Institute, 

 Buffalo, N.Y., will act as co-leader of the team. 



From the large number of applicants 16 scientists have been selected as 

 team members. They come from the following countries: 



Argentine ( 1 ) Sweden ( 1 ) 



Brasil (1) Switzerland (2) 



India ( 1 ) Turkey ( 1 ) 



Indonesia (1) U.S.A. (3) 



Israel (1) U.S.S.R. (1) 



Poland (2) Yugoslavia (1) 



III Foreign guests 



Two American guests continued their stay at the Laboratory in 1967. 

 Dr. L. Hearson (East Lansing, Mich.) left in May, and Dr. J. E. Foret 

 (Princeton, N.J.) in August. They both studied aspects of limb regeneration 

 in the axolotl with various techniques, including chemical treatment, autoradio- 

 graphy, and tissue culture. 



Miss R. Czolowska (Warsaw), a former member of the fifth international 

 team in embryology (1965), came again to the Laboratory in February for a 

 period of one year, to continue her cytochemical study of the germinal cyto- 

 plasm in oocytes of Xenopus. 



Dr. K. L. Duke (Durham, N.C.) visited the Laboratory for three weeks in 

 the spring, to study material from the Central Embryological Collection per- 

 tinent to the ovarial histology of Tarsias. 



Dr. J. G. Hollyfield (Austin, Tex.) arrived in September for a stay of one 

 year. He studies mitotic activity and cell migration in the layers of the retina 

 of the amphibian eye during metamorphosis. 



IV Facilities for international use 



These facilities comprise the Central Embryological Collection, and the 

 Central Embryological Library, with its extensive reprint collection, and its 

 bibliographical service and copying service. Details pertinent to these facilities 

 may be found in the information booklet distributed on a large scale in 1966. 

 This booklet is available on request, but the supply is limited. A special leaflet 

 describing the Central Embryological Library and its facilities is also available 

 on request.
