We briefly announce this volume in the interest of our readers, particularly those 

 working on cellular slime moulds. The NATO Advanced Study Institute in question was 

 held in Bellagio in September 1975. Sixof the 32 research reports deal with D/crvo^reZ/wm, 

 particularly with cell-surface lectins and cyclic AMP receptors (one deals with a macro- 

 molecular effector of cell differentiation). The authors are Barondes and Rosen and their 

 group, Gerisch, Malchow et al, Town, and Darmon et al. 



Other papers deal with sponge cell aggregation (Burger's group), adhesion of neurons 

 (Gottlieb's group), and membrane components in differentiating muscle cells (Prives).

N. MULLER-BERAT, ed. 1976. PROGRESS IN DIFFERENTIATION RESEARCH, 



proceedings of the Second International Conference on Differentiation, Copenhagen, 

 Denmark, 8-12 September, 1975 



North-Holland, Amsterdam; Amer. Elsevier, New York. X, 588 pp., 241 figs., 2 pis., 

 69 tabs., index to contributors and subject index. $ 46.25, Dfl. 120.00 



This conference brought together a large number of workers from all over the world. 

 Among the contributors were established authorities but also many younger people. Like 

 the report of the first conference in this series the book is heterogeneous but provides a 

 useful cross section of the many different approaches and systems being used at present. 

 Most of the contributions are short research reports or reviews of recent work. 



The 58 contributions are grouped into six sections as follows: Cell proliferation, 

 growth and expression of differentiation potential by proliferating cells (9 papers); Regul- 

 ation of gene activity and chromatin activity during cell differentiation (11); Cell mem- 

 branes and ceU surfaces in relation to differentiation (4); Aspects of carcinogenic dis- 

 orders and differentiation (15); Hormonal induction of cell differentiation (7); Normal 

 and malignant hemopoiesis as a model of differentiation (12). No group discussions are 

 recorded. 



The book is produced from typescripts in good offset print and profusely illustrated; 

 the numerous photographs are well reproduced. The subject index is curiously deficient.
