Mouse Yolk Sac Hematopoiesis [PDF]
Frontiers in Cell and Developmental Biology, 2018 The yolk sac is the first observed site of hematopoiesis during mouse ontogeny. Primitive erythroid cells are the most well-recognized cell lineages produced from this tissue. In addition to primitive erythroid cells, several types of hematopoietic cells

Differential regulation of fetal bone marrow and liver hematopoiesis by yolk-sac-derived myeloid cells [PDF]
Nature CommunicationsFetal hematopoiesis takes place in the liver before colonizing the bone marrow where it will persist for life. This colonization is thought to be mediated by specification of a microenvironment that selectively recruits hematopoietic cells to the nascent
