Communications from tLe HubrecLt Laboratory 



I The scientific staff 



In the beginning of 1968 a tenth member joined the staff: Mr. B. Z. Salome, 

 M.Sc. He acts as chief librarian and supervises and coordinates all work con- 

 nected with the Central Embryological Library, and with scientific information 

 dissemination both inside and outside the Laboratory. 



II The international team project 



The sixth international team in embryology met from February 1st till July 

 31st, 1968. Its central topic was: "Cell contacts and their role in morphogenesis 

 and cytodifferentiation". The co-leader of the team, Prof. L. Weiss of the 

 Roswell Park Memorial Institute, Buffalo, N.Y., was present during several 

 weeks at the beginning of the team period. A series of introductory lectures 

 were given by him and by the entire staff of the Laboratory; several faculty 

 members of the University of Utrecht also lectured on specific topics during 

 this programme. 



Three of the 1 6 accepted members had to withdraw for various reasons. The 

 team ultimately consisted of the following members: 



Dr. R. Adler (Buenos Aires, Argentine) 



Dr. D. Beig (Rio Claro, Brasil) 



Dr. Beth Burnside (Austin, Tex., U.S.A.) 



Dr. R. Hauser (Bern, Switzerland) 



S. Kochav, M.Sc. (Jerusalem, Israel) 



Dr. Louise Luckenbill (Boston, Mass., U.S.A.) 



Dr. J. Marthy (Basel, Switzerland) 



Dr. Teresa Rogulska (Warsaw, Poland) 



Miss Aysel Seftalioglu, M.Sc. (Ankara. Turkey) 



Dr. A. Scislawski (Krakow, Poland) 



Dr. R. Singh (Jaipur, India) 



Miss Sri Sudarwati, M.Sc. (Bandung, Indonesia) 



Dr. A. Svajger (Zagreb, Yugoslavia) 

 The members carried out a variety of research projects planned so as to fit 

 into the research programmes of the Laboratory's various research units. 



The seventh team will probably meet in 1971 or 1972. A circular pertaining 

 to this team will be distributed about 1 8 months in advance. 



Ill Fo reign guests 



Miss R. Czotowska (Warsaw) finished her cytochemical study of the 

 germinal cytoplasm in oocytes of Xenopus, and returned to Poland in March 

 1968. 



Dr. J. G. Holly field (Austin, Tex.) continued his study of mitotic activity 

 and cell migration in the layers of the retina of the amphibian eye during 

 metamorphosis. 



Dr. K. Ulrich (Kgs.Lyngby, Denmark) visited the Laboratory during 

 February 1968 to learn the technique of cell electrophoresis and to take part in 

 discussions of the international team. 



Dr. Rosine Chandebois (Marseille) stayed at the Laboratory in May to 

 learn experimental techniques with amphibian embryos. Also during May, short
