Human RBC precursors are obtained by (i) separating glycophorin A(+) (gly A(+)) cells using a magnetic cell sorting (MACS) technique and by (ii) ex vivo expansion of precursors BFU-E (burst forming unit-erythroid) on methylcellulose semi-solid culture media from mononuclear cells of cord blood.
We have seen blood consist of cells known as formed elements of blood. These cells have their own functions and roles to play in the body. Red blood cells (RBCs): RBCs are the biconcave cells; also known as erythrocytes. RBCs contain the iron-rich protein called haemoglobin; give blood its red color.
