What is the first recognizable erythroid precursor?
What gives rise to a Proerythroblast?
The erythropoietin-senstive progenitor cell (CFU-E)
The maturation of erythrocytes
What occurs during erythropoiesis?
- Cell volume decreases - Nucleus diameter decreases, chromatin condenses, nucleus is extruded - Cytoplasm has a decreased number of polyribosomes, increased hemoglobin, and mitochondria and other organelles disappear
In what cells of erythropoiesis does mitosis occur?
It occurs in proerythroblasts, basophilic erythroblasts, and polychromatic erythroblasts
When are erythrocytes released into circulation?
As soon as they are formed
What regulates erythrocyte formation and release?
What is the lifespan of erythrocytes?
about 120 days
What induces CFU-GEMM to differentiate into CFU-GM and then CFU-G?
