Bst1 (Bone marrow stromal cell antigen 1, ADP-ribosyl cyclase 2, CD157) is an enzyme that in humans is encoded by the BST1 gene. [ 5 ] [ 6 ] [ 7 ] CD157 is a paralog of CD38 , both of which are located on chromosome 4 (4p15) in humans.
Stromal tissue falls into the "functional" class that contributes to the body's support and movement. The cells which make up stroma tissues serve as a matrix in which the other cells are embedded. [2] Stroma is made of various types of stromal cells. Examples of stroma include: stroma of iris; stroma of cornea; stroma of ovary; stroma of ...
Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. [2] In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). [3] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
Bone marrow was the original source of MSCs, [16] and is still the most frequently utilized source. These bone marrow stem cells do not contribute to the formation of blood cells, and so do not express the hematopoietic stem cell marker CD34. They are sometimes referred to as bone marrow stromal stem cells. [17]
Stromal cells, or mesenchymal stromal cells, are differentiating cells found in abundance within bone marrow but can also be seen all around the body. Stromal cells can become connective tissue cells of any organ , for example in the uterine mucosa ( endometrium ), prostate , bone marrow , lymph node and the ovary .
Stroma of ovary, a soft tissue, well supplied with blood, consisting of spindle-shaped cells with a small amount of connective tissue; Stroma of iris, fibres and cells in the iris; Stroma of cornea, plates of collagen fibrils in the cornea; Lymph node stromal cell, cells which provide a scaffold for other lymph node cells; Stroma of bone marrow
Vertebrate hematopoietic stem cells niche in the bone marrow is formed by cells subendosteal osteoblasts, sinusoidal endothelial cells and bone marrow stromal (also sometimes called reticular) cells which includes a mix of fibroblastoid, monocytic and adipocytic cells (which comprise marrow adipose tissue). [1]
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 ...
