Developmental Mechanics of Chicken and Duck Embryos

TLDR: Some experiments which I have recently performed on young chicken and duck embryos in vitro using the ‘watch-glass technique’ employed at the Strangeways Laboratory for the cultivation of embryonic organs, although the rates both of differentiation and of growth are slower in vitro than in vivo.

Abstract: IT has recently proved possible to cultivate young chicken and duck embryos in vitro, using the ‘watch-glass technique’ employed at the Strangeways Laboratory for the cultivation of embryonic organs. Experiments using a somewhat similar technique were made in this laboratory two or three years ago by T. S. P. Strangeways and D. H. Strangeways, but the work was given up after a few trials and the results never published. The embryos can easily be kept alive for two or three days and differentiate nearly normally, although the rates both of differentiation and of growth are slower in vitro than in vivo. I wish here to summarise some experiments which I have recently performed on this material: full reports will be published in the near future.
