Induction and differentiation of an epithelial tumour in the newt (Triturus cristatus).
W A D D I N G T O N (1935) and later Needham (1936) have suggested that the autonomy of tumours originates in a 'morphological escape' of tumour cells from the controlling influence of an individuation field which has locally become weak or has vanished. The persistence and strength of such an individuation field can be seen in its ability to induce its parts to regeneration (Ruben, 1955). This...
متن کاملSex reversal of the newt Triturus cristatus reared at extreme temperatures.
Crested newt larvae were reared at defined temperatures, either from uncleaved eggs or from early feeding larvae, until metamorphosis when sexual differentiation had occurred. Trials at 18-24 degrees C showed a 1:1 sex ratio. A higher temperature trial produced more males than females, including some XX neomales. Lower temperatures resulted in a significant excess of females, including XY neofe...
متن کاملDigit regeneration in the amphibian--Triturus cristatus.
Digit regeneration has been examined in Triturus cristatus. Because of their size, blastemas that form after digit amputation are relatively a lot more suitable for quantitative studies that involve for example the counting of cells in histological sections. They are also very useful for the study of some basic histological aspects of regeneration particularly cartilage formation. This has been...
متن کاملThe Occurrence and Possible Significance of Haemoglobin in the Chromosomal Regions of Mature Erythrocyte Nuclei of the Newt Triturus Cristatus Cristatus
Absorption measurements in violet light (lambda 4047 A) of thin sections of mature newt erythrocytes have indicated the presence of a haem compound, probably haemoglobin, within the chromosomal regions of the nucleus. The amount is about 45 per cent of that in the cytoplasm. The possible significance of this nuclear haemoglobin in determining nuclear structure is discussed in terms of the elect...
متن کاملThe form and structure of supernumerary hindlimbs formed following skin grafting and nerve deviation in the newt Triturus cristatus.
The results of a series of skin grafting experiments performed on the hindlimb of the newt Triturus cristatus are described. In an attempt to limit the position of origin and the complexity of supernumerary limb outgrowths four experimental features were varied. These were 1) size of skin grafts; 2) their position of origin; 3) the position to which they were grafted; and 4) the presence or abs...
