BACKGROUND Previous studies have shown that the numbers of both circulating hematopoietic progenitor cell (HPC) and CD34(+) cell are positively correlated with CD34(+) cell harvest yield. However, the minimal numbers of both circulating HPCs and CD34(+) cells required for performing an efficient hematopoietic stem cell (HSC) harvest in lymphoma and myeloma patients have not been defined in our ...
Hepatic stellate cell (HSC) activation is a key event in the natural process of wound healing as well as in fibrosis development in liver. Current in vitro models for HSC activation contribute significantly to the understanding of HSC biology and fibrogenesis but still fall far short of recapitulating in vivo intercellular functional and anatomic relationships. In addition, when cultured on unc...
Hepatic stellate cells (HSC), the key fibrogenic cells of the liver, transdifferentiate into myofibroblasts upon phagocytosis of apoptotic hepatocytes. Galectin-3, a β-galactoside-binding lectin, is a regulator of the phagocytic process. In this study, our aim was to study the mechanism by which extracellular galectin-3 modulates HSC phagocytosis and activation. The role of galectin-3 in engulf...
Bone marrow hematopoietic stem cells (HSCs) are responsible for both lifelong daily maintenance of all blood cells and for repair after cell loss. Until recently the cellular mechanisms by which HSCs accomplish these two very different tasks remained an open question. Biological evidence has now been found for the existence of two related mouse HSC populations. First, a dormant HSC (d-HSC) popu...
Hepatic stellate cell (HSC) proliferation is a key event in liver fibrosis; therefore, pharmacological intervention with antiproliferative drugs may result in antifibrotic effects. In this article, the antiproliferative effect of three cytostatic drugs was tested in cultured rat HSC. Subsequently, the antifibrotic potential of the most potent drug was evaluated in vivo. As a strategy to overcom...
Following liver injury, the wound-healing process is characterized by hepatic stellate cell (HSC) activation from the quiescent fat-storing phenotype to a highly proliferative myofibroblast-like phenotype. Snail1 is a transcription factor best known for its ability to trigger epithelial-mesenchymal transition, to influence mesoderm formation during embryonic development, and to favor cell survi...
BACKGROUND The causes of female infertility are multifactorial and necessitate comprehensive evaluation including physical examination, hormonal testing, and imaging. Given the associated psychological and financial stress that imaging can cause, infertility patients benefit from a structured and streamlined evaluation. The goal of such a work up is to evaluate the uterus, endometrium, and fall...
Introduction: Precision-cut liver slices are a promising alternative to cell culture models for the study of hepatic stellate cell (HSC) activation and fibrogenesis since HSC are maintained in their original extracellular matrix and multicellular milieu. In the present study we evaluated human liver slices as a tool to study fibrogenesis and to test antifibrotic drugs. Methods: Firstly we deter...
Hematopoietic stem cell transplantation (HSCT) is an important therapy for patients with a variety of hematological malignancies. HSCT would be greatly improved if patient-specific hematopoietic stem cells (HSCs) could be generated from induced pluripotent stem cells in vitro. There is an incomplete understanding of the genes and signals involved in HSC induction, migration, maintenance, and ni...
