| Admin Total Posts: 890 | Posted: Tue Apr 15, 2008 05:35 am Williams - "Interestingly, the timing of the production of each of these early hemoglobin versions corresponds to changes in the site of hemoglobin production. As Figure 7-10 illustrates, fetal blood is first produced in the yolk sac, where hemoglobins Gower 1, Gower 2, and Portland are made. Erythropoiesis then moves to the liver, where hemoglobin F (fetal hemoglobin) is produced. When hemopoiesis finally moves to the bone marrow at around 11 weeks, normal hemoglobin A appears in fetal red cells and is present in progressively greater amounts as the fetus matures (Pataryas and Stamatoyannopoulos, 1972)." |
| LeMans Total Posts: 16 | Posted: Tue Apr 15, 2008 02:57 pm acc to harrison-16 th edition pg 594 under 'developmental biology of human hemoglobin' "The switch to nearly exclusive synthesis of adult hemoglobin(Hb A)occurs at about 38 weeks of gestation." "At 10 to 11 weeks,fetal hemoglobin becomes predominant." does the question refer to beginning of hb a synthesis or the time when it becomes the dominant hb ? |
