The role of stem cells in cancer formation and spreading has been established. As with normal tissue, the cancer stem cells need a special microenvironment to support their growth. This microenvironment may be represented by the tumor stroma. One of the possible ways of tumor stromal formation is the epithelial-mesenchymal transition of tumor epithelium. Following this mechanism, stromal cells ...
The placenta, a transient organ in human, is essential for pregnancy maintenance and for fetal growth and development. Trophoblast and stromal cells are the main cell types present in human placenta. Trophoblast cells are present in different subtypes depending on their differentiation state and their temporal and spatial location during pregnancy. The stromal cells are of extraembryonic mesenc...
In both preclinical and clinical studies, cell transplantation of several cell types is used to promote repair of damaged organs and tissues. Nevertheless, despite the widespread use of such strategies, there remains little understanding of how the efficacy of cell therapy is regulated. We showed previously that augmentation of a unique, metabolically derived stress signal (i.e., O-GlcNAc) impr...
Multipotent mesenchymal stromal cells (MSCs) have generated considerable interest in the fields of regenerative medicine, cell therapy and immune modulation. Over the past 5 years, the initial observations that MSCs could enhance regeneration and modulate immune responses have been significantly advanced and we now have a clearer picture of the effects that MSCs have on the immune system partic...
Extracellular vesicles (EV) awakened interest in the research on mesenchymal stromal cells by exploring their paracrine effects. However, many isolation protocols use bovine serum albumin (BSA) during the preparation of the EV. Therefore, we produced 'sham' BSA-EV and tested them in comparison to EV derived from mesenchymal stromal cells (MSC-EV). We found that BSA-EV did not express MSC-specif...
Liver becomes the predominant site of hematopoiesis by 11.5 dpc (days after coitus) in the mouse and 15 gestational weeks in humans and stays so until the end of gestation. The reason the liver is the major hematopoietic site during fetal life is not clear. In this work, we tried to define which of the fetal liver microenvironmental cell populations would be associated with the development of h...
Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...
Abstract Easy, quantitative measures of biomolecular heterogeneity and high-stratified phenotyping are needed to identify characterise complex disease processes at the single-cell level, as well predict cell fate. Here, we demonstrate how Raman spectroscopy can be used in difficult-to-assess case clonal, bone-derived mesenchymal stromal cells (MSCs) MSC lines group these according biological fu...
Telocytes (TCs) are a type of interstitial cells with essential roles in regenerative medicine. TCs spatially exist the stem cell niche and considered ‘stem helper cell’. Mesenchymal stromal therapy has been widely used treating lung diseases, while there is increasing evidence from preclinical studies to show beneficial effects support smooth muscle treat by releasing paracrine factors, exosom...
objective(s): bone marrow-derived mesenchymal stem cells (bm-mscs) potentials make them appropriate for cell therapy including ability of differentiation and release of anti-inflammatory cytokines and growth factors secreta. for treatment of azoospermia to induce proliferation and differentiation of germ cells, mscs transplantation has been introduced. the aim of the present experimental case-c...
