Extra- and Intraembryonic HSC Commitment in the Avian Model,ntiality and self-renewal capacity, setde in the bone marrow where they can differentiate into progenitors with more restricted lineage potential and generate all blood lineages via a cascade of commitment events. However HSC are generated during the earliest phases of embryonic development into spe意见一致 发表于 2025-3-27 01:26:45
Avian Lymphopoiesis and Transcriptional Control of Hematopoietic Stem Cell Differentiation, stem cells in the embryo proper has increased in last years. In an avian model the primitive erythropoiesis derived from extraembryonic yolk sac is short lived and the evidence that adult hematopoiesis arises from intraembryonic sources has been extended from birds to mammals.

Endothelial and Hematopoietic Cells in the Intraembryonic Compartment,ngioblast. Differentiation into hematopoietic and endothelial lineages begins with proliferation of a single layer of mesodermal cells in the yolk sac resulting in formation of cell clusters, the blood islands. Cells at the periphery of these mesodermal aggregations differentiate into angioblasts. BTRUST 发表于 2025-3-27 23:56:04

Intraembryonic Development of Hematopoietic Stem Cells during Human Ontogeny: Expression Analysis, It is generally believed that all these cell types derive, through a series of maturing progenitors, from a common stem cell, which first appears during embryogenesis and persists into adult life. This hematopoietic stem cell (HSC) is defined by its ability to self-renew and to generate cells of al正面 发表于 2025-3-28 13:26:43
