A 15 day old chick embryo, and its developing organs, are revealed inside an egg.
Zooming into a young B Cell nucleus, an animation depicting gene rearrangement is shown.
B Cells then cross into epithelial buds, probably following dendritic cell chemoattractants.
Zooming back into the nucleus, gene conversion is observed (‘2D on screen’, and then 3D).
The chick hatches with a diverse B cell repertoire, thanks to gene conversion.
