introduction: recognition of human leukocyte antigens (hla) is of importance for hematopoietic stem cell transplantation. any hla-mismatches between the donor and recipient can cause graft rejection or other complications. in hla-typing experiments, usage of hla-known reference cells accompany with hla-unknown samples is obligatory. some international centers represent these cells with high exp...

the sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. the passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematopoieti...

Hematopoietic reconstitution (HR) after peripheral blood stem cell transplantation is characterized by a delay of 8 and 12 days for recovery to safe levels of neutrophils and platelets even in patients with the most rapid engraftment. We postulate that a further enhancement in the rate of HR may be achieved by transplanting with an expanded postprogenitor cell population that can provide mature...

Shifting sites of blood cell production during development is common across widely divergent phyla. In zebrafish, like other vertebrates, hematopoietic development has been roughly divided into two waves, termed primitive and definitive. Primitive hematopoiesis is characterized by the generation of embryonic erythrocytes in the intermediate cell mass and a distinct population of macrophages tha...

Background: Natural killer (NK) cells originate from the differentiation of hematopoietic stem (HSCs) in common lymphoid progenitor pathway, and HSCs can be obtained umbilical cord blood (UCB). Comparative studies NK cell between cultured freshly isolated are important development therapy for cancer. This study aimed to compare maturation stages newly HSC samples using interleukin-2 absence fee...

embryonic stem cells (escs) as pluripotent stem cells have the potential to give rise to all three germ layer cells. also, these cells have the self-renewing ability. escs could differentiate into most of cell lineages. lymphocytes generated from hematopoietic stem cells. we designed a feeder free culture condition to generate lymphoid lineage cells from escs. we demonstrated that il-7 plays cr...

Erythropoietin (Epo), granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor- (G-CSF) dependent cell lines have been derived from the murine hematopoietic cell line 32D with a selection strategy involving the culture of the cells in FBS-deprived medium supplemented only with pure recombinant Epo, GM-CSF, or G-CSF. The cells retain the diploid karyoty...

Embryonic Hematopoiesis In article number 2205345, Fudi Wang, Junxia Min, and co-workers identify demonstrate indispensable function of zinc transporter SLC39A10 (ZIP10) its mediated homeostasis for maintaining the survival fetal hematopoietic stem/progenitor cells. As most important importer on cell membrane stem cells, ZIP10 functions as a gatekeeper (like vacuum to transport across membrane)...
