Zebrafish embryonic red blood cells (RBCs) develop in trunk intermediate mesoderm (IM), and early macrophages develop in the head, suggesting that local microenvironmental cues regulate differentiation of these two blood lineages. s padetail (spt) mutant e ...
IgG autoantibodies against the alpha-chain of the high affinity IgE receptor are claimed to play a pathogenetic role in autoimmune urticaria. The best methods for detection of functional autoantibodies are currently the autologous serum skin test and the b ...
Angiogenic tumor vessels are promising targets for the activity and the selective delivery of cancer therapeutics. The bone marrow contributes different cell types to the tumor stroma, including hematopoietic cells and, as recently suggested, vascular endo ...
Notch signaling regulates many cell fate decisions during development of multi-cellular organisms. Signals initiated by Notch influence a wide variety of processes that include lineage specification, cell survival and proliferation, and border formation. D ...
We envision the use of human fetal bone cells for engineered regeneration of adult skeletal tissue. A description of their cellular function is then necessary. To our knowledge, there is no description of human primary fetal bone cells treated with differe ...
Allogeneic MHC-incompatible organ or cell grafts are usually promptly rejected by immunocompetent hosts. Here we tested allogeneic beta-islet cell graft acceptance by immune or naive C57BL/6 mice rendered diabetic with streptozotocin (STZ). Fully MHC-misma ...
Members of the Ets gene family are known to be expressed in the hematopoietic tissue and some of them play a pivotal role in normal hematopoietic cell development. Ets-1 gene expression was analyzed in Friend Leukemia Cells (FLC) induced to erythroid diffe ...
BACKGROUND: Autologous transplantation is an attractive approach to treat some neurological diseases. A major obstacle is the capacity to produce cells for transplantation at the appropriate time. We describe a cryopreservation procedure for adult human br ...
Successful photodynamic therapy of epithelial cancer requires a specific photosensitization of malignant tissue. We evaluate the intensity and localization of protoporphyrin IX (PpIX) in superficial transitional cell carcinoma and nonmalignant cells of the ...
Efficient vector transduction of hematopoietic stem cells is a requirement for successful gene therapy of hematologic disorders. We asked whether human umbilical cord blood CD34(+)CD38(lo) nonobese diabetic/severe combined immunodeficiency (NOD/SCID) repop ...
