Question

Quizplus · Accepted Answer

All blood cells originate from a single type of cell called a stem cell. Stem cells have the ability to differentiate into different types of blood cells, including erythrocytes (red blood cells), leukocytes (white blood cells), and platelets. Cytokines are proteins that regulate the immune response and inflammation, but they do not directly give rise to blood cells.
