(18) It appears that the avian allantois, in addition to its role in respiration and urea disposal, also serves the instant CA removal from the circulation.
(19) Around the 8th day p.c., the allantois reaches contact with the ectoplacental cone, which develops into the chorioallantoic (definitive) placenta.
(20) It has been shown that capillary formation in chorion-allantois membranes of chicken embryos under the influence of tumour necrosis factor (TNF) on neovascularization process depends on the dose applied and that the character of this influence may be different.
