14 Questions
Where do most plastic cells in the adult body originate from?

What happens as the hematopoiesis process progresses?
Cells lose their multipotent ability and gain specific functions
What are Colony Forming Units (CFUs) responsible for?
Giving rise to other cells
Where does myelopoiesis occur?
Bone marrow
What is the fate of monocytes during hematopoiesis?
They form macrophages in tissues
Where does lymphopoiesis occur?
Lymphoid organs
Which of the following conditions is characterized by severe reduction/absence of reticulocytes and all erythron in the bone marrow?
Aplastic anemia
Which of the following anemias is characterized by a lack/reduction of precursor and progenitor cells, resulting in absence of erythroblasts in the bone marrow?
Aplastic anemia
Which condition is often associated with BM aplasia and can be caused by thymoma, carcinomas, or hematologic neoplastic diseases?
Acquired erythroblastopenia (aplastic anemia)
Which type of anemia is primarily due to damage in erythroblasts' precursors, resulting in reduced erythroblastogenesis?
Congenital erythroblastopenia
Which condition can cause a transient reduction in one or all bone marrow lineages, including a decrease in erythroblasts?
Viral infections
Which type of anemia is characterized by reduced RBC survival and can be caused by autoimmune hemolysis or erythrocyte structural and metabolic dysfunction?
Autoimmune hemolysis
Which condition is characterized by reduced hemoglobin synthesis, either in the Heme or in the Globin part?
Thalassemias
(Select all that apply) Which conditions are often characterized by BM aplasia?
(Aplastic anemia)
This quiz covers the basics of hematopoiesis, the process through which blood-circulating cells originate from stem cells in the bone marrow. It explores the differentiation of pluripotent stem cells into various precursor cells and their specific functions in the body.
