Stromal cell-associated erythropoiesis.
A novel cover slip-transfer culture system was designed to study the functional roles of stromal cells in hemopoiesis, particularly erythropoiesis. Human bone marrow stromal cell colonies were allowed to develop on small glass cover slips in liquid medium. The cover slips, along with the stromal cell colonies and progenitors attached to them were then transferred to a new tissue culture dish an...
متن کاملA stromal myoid cell line provokes thymic erythropoiesis between 16th to 20th weeks of intrauterine life.
BACKGROUND The thymus provides an optimal cellular and humoral microenvironment for cell line committed differentiation of haematopoietic stem cells. The immigration process requires the secretion of at least one peptide called thymotaxine by cells of the reticulo-epithelial (RE) network of the thymic stromal cellular microenvironment. The thymic RE cells are functionally specialised based on t...
متن کاملStromal cell-associated hematopoiesis: immortalization and characterization of a primate bone marrow-derived stromal cell line.
An elucidation of the interaction between the bone marrow microenvironment and hematopoietic stem cells is critical to the understanding of the molecular basis of stem cell self renewal and differentiation. This interaction is dependent, at least in part, on direct cell to cell contact or cellular adhesion to extracellular matrix proteins. Long-term bone marrow cultures (LTMC) provide an approp...
متن کاملCarbon monoxide production associated with ineffective erythropoiesis.
The rate of endogenous carbon monoxide production ( Vco), determined by the closed rebreathing system technique, was elevated above the normal range in four of five patients studied with ineffective erythropoiesis (four patients with primary refractory anemia, one with thalassemia). The mean molar ratio of Vco to Vheme (rate of circulating heme catabolism, determined from (51)Cr red cell surviv...
متن کاملCell-intrinsic requirement for pRb in erythropoiesis.
Retinoblastoma (Rb) and family members have been implicated as key regulators of cell proliferation and differentiation. In particular, accumulated data have suggested that the Rb gene product pRb is an important controller of erythroid differentiation. However, current published data are conflicting as to whether the role of pRb in erythroid cells is cell intrinsic or non-cell intrinsic. Here,...
