M.BALLS and F.S.BILLETT, eds. 1973. THE CELL CYCLE IN DEVELOPMENT AND 



DIFFERENTIATION 



Cambridge Univ. Press, London. XII, 483 pp., 128 figs., 14 pis., 58 tabs., combined sub- 

 ject and taxonomic index. £ 1 1.00, $ 32.50 



This book contains the 26 papers presented at a symposium held in Bristol in July 

 1972. Most of the contributors came from Great Britain, but there were several from 

 other Western-European countries. The contributions vary widely in scope. 



Two introductory reviews deal with differentiation within the cell cycle (Mitchison, 

 12 pp.) and with the measurement of the intermitotic period (Steel, 18 pp.). Two other 

 contributions are pure reviews, size are mixtures of review and research report, and the 

 remainder are reports on recent research in special areas, some only a few pages long. Yet 

 together they provide an interesting survey of what is going on in this field in Britain and 

 parts of Europe. The range of organisms involved in this work comprises slime moulds 

 and ciliates, lower and higher plants, invertebrates, and vertebrates. 



The book is well produced and illustrated. It has an extensive index.

S.BONOTTO, R.GOUTIER, R.KIRCHMANN, and J.R.MAISIN, eds. 1972. BIOLOGY 



AND RADIOBIOLOGY OF ANUCLEATE SYSTEMS 



Academic Press, New York, etc. 



Vol. I Bacteria and animal cells. XVIII,227 pp. $ 7.00 



Vol. II Plant cells. XX,368 pp., 191 figs., 6 tabs. $ 1 1.00 



Although vol. I of this symposium report was not available for review, we briefly 

 review vol. II because of the intrinsic interest of the subject. The Symposium was held in 

 Mol, Belgium in June 1971. 



Vol. II contains 16 papers on plant cells. Most of the contributors came from five 

 Western-European countries. One contribution by a group from Novosibirsk (U.S.S.R.) 

 was read by title. Of the 16 papers, nine are concerned partly or entirely with problems 

 of development and morphogenesis in unicellular algae: five on A cetabularia and four on 

 Micrasterias. 



Vol. I contains an opening lecture by Brachet and 1 1 papers on work with bacteria and 

 animal cells.

CIBA - Symposium. 1973. HAEMOPOIETIC STEM CELLS 



Elsevier - Excerpta Medica -- North-Holland, Amsterdam, etc. X,345 pp., 84 figs., 

 33 tabs., index to contributors, subject index. D.fl. 44.00, ca. U.S. $ 19.00 



This symposium was held in London in July, 1972. Attendance was truly inter- 

 national, and encompassed both morphologists and physiologists. As with most Ciba 

 Symposia the book is a must for all those who are themselves working in this field. 

 However, a large proportion of the 13 papers and the group discussions held is of interest 

 to those working on cell differentiation generally. 



The following aspects may be highlighted: morphological identification of stem cells, 

 kinetics of proliferation in cell populations, differentiation in cell populations and its 

 interplay with proliferation, hormonal and cell-to-cell controls in cell differentiation, and 

 the role of the micro-environment. 



As usual the book's production is excellent and the price reasonable.
