The production of heat in the fertilized eggs, during the early development of the Japanese pond frog, Rana brevipoda porosa, was measured using a pyroelectric detector constructed with a polyvinylidene fluoride film. One and 2 渭W of heat production was detected during the cleavage periods in ...

Translation regulation is critical for early mammalian embryonic development1. However, previous studies had been restricted to bulk measurements2, precluding precise determination of translation regulation including allele-specific analyses. Here, to address this challenge, we developed a novel microfluidic i...

(1) During the first 5 weeks of development, the neuroepithelium proliferated and the dorsal metencephalic plates increased in size. (2) Starting in the sixth week, a patch of neuroepithelium began to differentiate and gave rise to a small population of Purkinje cells. In subsequent weeks, ...

Embryonic cells grow in environments that provide a plethora of physical cues, including mechanical forces that shape the development of the entire embryo. Despite their prevalence, the role of these forces in embryonic development and their integration with chemical signals have been mostly neglected,...

I suggest that eggs from these two ponds differed genetically in the growth and development strategy. Despite the obvious risks, and the moderate gain in terms of early metamorphosis, frogs breed dangerously early in spring. Possible reasons for this are discussed. These include external selective ...
