Example text

Cleavage and development of the embryo are oriented with regard to the original polarity, and are independent of the direction in which the centrifugal force has been operating. Evidently, the factors governing polarity have not been shifted by the centrifuging; they must be inherent in a component of the egg that is not moved by the centrifugal force. Presumably this is the more solid outer layer of the egg, the cortex. Polarity, then, depends on factors localised in the egg cortex; the axial gradients arise only as a result of these factors.

Here as a rule cleavage does not occur in fully-activated eggs, but only when activation is incomplete and polar body formation is suppressed. In these cases the presumptive maturation spindle may either be converted directly into a cleavage spindle, or so-called "subĀ­ merged" maturation divisions (without extrusion of polar bodies) may occur followed by fusion of nuclei and association of cytocentres. Apparently, the egg cytocentre under these circumstances does not lose its capacity for division.

In normal developĀ­ ment the parts that are suppressed by lithium develop from the cells lying around the animal pole of the egg. When eggs were exposed to a heat shock at an early cleavage stage, on the contrary this middle part of the head seemed to be reduplicated. From these experiments the conclusion was drawn that 54 POLARITY AND SYMMETRY; lithium and heat shock treatment act directly on the cortical field, and that this field has the character of a gradient-field, a certain property having its maximum value at the animal pole, and decreasing gradually from this point.
