Cell Lines as a Model for the Study of Metamorphosism a study of established insect cell lines. However, during the past 5 years the potential usefulness of such cell lines has been forcefully demonstrated in a number of laboratories (Courgeon, 1972, 1975; Cherbas .., 1977; Maroy .., 1978; Chang .., 1980). It seems appropriate prior to a detailed dis

This reproductive strategy is used by some species in all chordate classes excluding birds and mammals.

Cytological and Morphological Changes during Amphibian Metamorphosisical, physiological, and behavioral changes. Since it was first discovered that thyroid feeding of anuran larvae hastens metamorphic changes, a vast corpus of knowledge on the subject has accumulated. During premetamorphosis there is no effective level of hormonal secretion of the thyroid and its ac

The Dual Role of Thyroid Hormones in Vertebrate Development and Calorigenesisd hormone(s) (TH). A huge and bewildering array of observations has been published and has generated more confusion than clarification. The difficulty of successfully integrating these data has been compounded by the use of a wide range of TH dosages, from physiological (10. to 10. M) to pharmacolog
