Blood and blood vessels
Summary
Description
This original animation begins with an embryo at the end of the second week under low magnification. Then, it presents a segment of the splanchnopleuric layer lined by the endoderm of the yolk sac under high light microscopic magnification. Next, in an approximately 17-day-old embryo, the animation shows the formation of a blood island from the mesenchymal cells under the influence of endodermal signaling molecules.... (more)
This original animation begins with an embryo at the end of the second week under low magnification. Then, it presents a segment of the splanchnopleuric layer lined by the endoderm of the yolk sac under high light microscopic magnification. Next, in an approximately 17-day-old embryo, the animation shows the formation of a blood island from the mesenchymal cells under the influence of endodermal signaling molecules. Finally, it demonstrates the differentiation of mesenchymal cells into endothelial cells and blood cells, including stem cells.
The animation describes the medullary phase of fetal hematopoiesis, featuring the monophyletic theory of hematopoiesis via a pluripotent hematopietic stem cell (PHSC) and a pluripotent hematopoietic progenitor cell (PHPC).
One side of the diagram shows lymphopoiesis, while the other shows myelopoiesis.
The next sequence shows the formation of the B- and T-lymphocytes, a natural killer cell (NK), and a follicular dendritic cell (F) from a common lymphoid progenitor cell. The animation shows the diapedesis of all of these cells into the sinuses of the bone marrow. Myelopoiesis is animated in a similar manner as lymphopoiesis. Next, it presents the formation of CFU-G/M, CFU-Eo, CFU-Baso, CFU-Meg, and CFU-E from a common myeloid progenitor cell. In addition to the diapedesis of the leukocytes, erythrocytes, and an interdigitated dendritic cell into the blood sinus of the bone marrow, the animation also includes fragmentation of a megakaryocyte into platelets and their penetration into the sinus.
The following sequence illustrates the connection of extraembryonic and intraembryonic blood vessels starting from an embryo at the end of the 2nd week. First, a diagram shows the spreading of the splanchnopleuric blood islands and their connection with vessels around the allantois and in the chorionic plate. The next series shows the formation of the cardiogenic plate and the connection of extraembryonic and intraembryonic blood vessels.
A final diagram summarizes all phases of hematopoiesis (e.g. embryonic or mesodermal, hepatosplenic and medullary).
(This animation is essential for students of medicine, stomatology, veterinary medicine; it is also recommended for departments of internal medicine and hematology, biology students and hematologic technicians).
