That bone marrow is a priming site for T-cell responses to blood-borne antigens was first described in 2003. [13] Mature circulating naïve T cells home to bone marrow sinuses after they have passed through arteries and arterioles. [14] They transmigrate sinus endothelium and enter the parenchyma which contains dendritic cells (DCs).
A mongoose is a small terrestrial carnivorous mammal belonging to the family Herpestidae. This family has two subfamilies, the Herpestinae and the Mungotinae . The Herpestinae comprises 23 living species that are native to southern Europe , Africa and Asia , whereas the Mungotinae comprises 11 species native to Africa. [ 2 ]
The marsh mongoose is primarily a solitary species. [2] It is an excellent swimmer and can dive for up to 15 seconds, using its feet to paddle. On land, it usually trots slowly, but can also move fast. [14] Radio-collared marsh mongooses in KwaZulu-Natal were active from shortly after sunset until after midnight showing a crepuscular activity ...
Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [10] [11] [12] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical ...
The bone marrow of essentially all the bones produces red blood cells until a person is around five years old. The tibia and femur cease to be important sites of hematopoiesis by about age 25; the vertebrae , sternum , pelvis and ribs , and cranial bones continue to produce red blood cells throughout life.
Endothelial stem cells (ESCs) are one of three types of stem cells found in bone marrow. They are multipotent, which describes the ability to give rise to many cell types, whereas a pluripotent stem cell can give rise to all types. ESCs have the characteristic properties of a stem cell: self-renewal and differentiation.
Megakaryocytes are derived from hematopoietic stem cell precursor cells in the bone marrow. They are produced primarily by the liver, kidney, spleen, and bone marrow. These multipotent stem cells live in the marrow sinusoids and are capable of producing all types of blood cells depending on the signals they receive.
The ring-tailed vontsira (Galidia elegans), locally still known as the ring-tailed mongoose, is a euplerid in the subfamily Galidiinae, a carnivoran native to Madagascar. [2] It is the only species in the genus Galidia .
