This new manual provides a convenient source of experimental procedures, including the most modern and frequently used molecular and cellular techniques. Experimental protocols have been carefully selected by developmental toxicologists for developmental toxicologists. The most important new trends, such as evaluation of the safety of therapeutic antisense oligonucleotides, studies of the role of cell death in abnormal development, and the identification of sparingly expressed developmental control genes are featured. This is the perfect manual for scientists trained in classical developmental toxicology who want to add molecular and cellular methods to their research.
