Hematopoietic stem cells (HSCs) are the stem cells [1] that give rise to other blood cells.This process is called haematopoiesis. [2] In vertebrates, the first definitive HSCs arise from the ventral endothelial wall of the embryonic aorta within the (midgestational) aorta-gonad-mesonephros region, through a process known as endothelial-to-hematopoietic transition.
The following are the non-pulmonic consonants.They are sounds whose airflow is not dependent on the lungs. These include clicks (found in the Khoisan languages and some neighboring Bantu languages of Africa), implosives (found in languages such as Sindhi, Hausa, Swahili and Vietnamese), and ejectives (found in many Amerindian and Caucasian languages).
Myeloid neoplasms always concern bone marrow cell lineage and are related to hematopoietic cells. Myeloid tissue can also be present in the liver and spleen [ 5 ] in fetuses , and sometimes even in adults as well, which leads to extramedullary hematopoiesis .
