The RBC lifetime is about 120 days
The life cycle of a Red Blood Cell.
a) Kidneys respond to a lower than normal oxygen concentration in the blood by releasing the hormone erythropoietin.
b) Erythropoietin travels to the red bone marrow and stimulates an increase in the production of red blood cells (RBCs).
c) The red bone marrow manufactures RBCs from stem cells that live inside the marrow.
d) RBCs squeeze through blood vessel membranes to enter the circulation.
e) The heart and lungs work to supply continuous movement and oxygenation of RBCs.
f) Damaged or old RBCs are destroyed primarily by the spleen.
What is artificial blood?
Blood produced from stem cells and can be manufactured as type “O-negative”, which is produced by only 7 % of the World and is suitable for use in up to 98 % of population.
A success story…
“A French doctor has completed the first-ever artificial blood transfusion after extracting stem cells from a patient‘s bone marrow, which were then used to grow the red blood cells under laboratory settings. After five days, 94 to 100 percent of the blood cells remained circulating in the body. After 26 days, 41 to 63 percent remained, which is a normal survival rate for naturally produced blood cells. The cells carried oxygen throughout the patient’s body, just as normal red blood cells would.”
