The sequence of developmental steps in the formation of red blood cells beginning with hematopoietic stem cells is:
A) proerythroblasts, polychromic erythroblasts, basophilic erythroblasts, and reticulocytes.
B) proerythroblasts, reticulocytes, polychromic erythrocytes, and basophilic erythrocytes.
C) proerythroblasts, basophilic erythroblasts, polychromic erythroblasts, and reticulocytes.
D) polychromic erythroblasts, basophilic erythroblasts, proerythroblasts, and reticulocytes.

Question

Quizplus · Accepted Answer

Hematopoietic stem cells differentiate into proerythroblasts, which then become basophilic erythroblasts. These basophilic erythroblasts will then develop into polychromic erythroblasts and subsequently into reticulocytes, which mature into red blood cells. Therefore, the correct sequence is proerythroblasts, basophilic erythroblasts, polychromic erythroblasts, and reticulocytes.
