The chicken embryo is a unique model that overcomes many limitations to studying the biology of cancer in vivo. The chorioallantoic membrane (CAM), a well-vascularized extra-embryonic tissue located underneath the eggshell, has a successful history as a biological platform for the molecular analysis of cancer including viral oncogenesis, [8] carcinogenesis, [9] tumor xenografting, [1] [10] [11 ...
Candling an egg. Candling is a method used in embryology to study the growth and development of an embryo inside an egg.The method uses a bright light source behind the egg to show details through the shell, and is so called because the original sources of light used were candles.
In this method, the eggs are first kept in inside a humidified incubator for up to a period of 3 days, to ensure that the position of the embryo is opposite to the position where the egg will be subsequently cracked. A small hole is made on the side of the air chamber to equilibrate the pressure, followed by the cracking of the egg on a petri-dish.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Eggshell membrane is the clear film lining the chicken eggshell displayed. Eggshell membrane or shell membrane is the clear film lining eggshells, visible when one peels a boiled bird egg. Chicken eggshell membranes are used as a dietary supplement. Eggshell membrane is derived commercially from the eggshells of industrial processors.
Buffalo Chicken Deviled Eggs My daughter Sara loves spicy Buffalo chicken and deviled eggs, so I combined the two. Make and chill a day ahead so the flavors mingle.
As soon as the butter begins to brown, I take the skillet off the heat, add the eggs, and immediately stir with a silicone spatula until the heat of the pan dies down and the scrambled eggs stop ...
The innermost membrane of all animal eggs except some cnidarians is called the vitelline membrane. Some invertebrates and some lower chordate eggs are covered by this membrane only, while most have other membranes. [10] Frog and bird eggs have a very thin vitelline membrane which are surrounded by either a jelly layer (frogs) or other membranes ...
