For cartilage replacement we established two novel ways to use decellularized cartilage matrix for cell therapy. (icgeb.org)
Cell therapy is a potential new treatment for post MI patients, but the main challenges are : the necessity to preserve immune competency and to gain adequate nutrition and homing signals necessary for stem cells' engraftment and survival. (escardio.org)
Repair of scar tissue constitutes a challenge for cardiac stem cell therapy due to lack of adequate nutrition and homing signals necessary for stem cells' engraftment and survival. (escardio.org)
Introduction Stem cell therapy with bone marrow-derived mononuclear cells (BMMCs) is an option for improving joint function in osteonecrosis of the femoral head (ONFH). (bioskinrevive.com)
If you are that patient, ask your orthopedic surgeon about A Novel Cell-based therapy in Orthopedic Surgery: Endothelial Progenitor Cells. (sheinkopmd.com)
Even though the potential is great, it will be a while before stem cell therapy can become a part of routine treatment. (ndtv.com)
Mesenchymal stem cells - a promising therapy for Acute Respiratory Distress Syndrome. (istanbul.edu.tr)

These cells are plastic-adherent, colony forming cells. (celprogen.com)
It is a key cytokine involved in the production of neutrophils and the stimulation of granulocyte colony formation from hematopoietic progenitor cells (Metcalf & Nicola). (stemcell.com)
thus, a successful metastatic colony depends on the ability of cancer cells to appropriate distinct microenvironments at each step in the metastatic cascade: the primary tumor, systemic circulation, and the final metastatic destination. (medscape.com)

Bone marrow mesenchymal stem cells (BMSCs) have been reported to attenuate myocardial I/R injury via their paracrine effects, which can be enhanced by hypoxic preconditioning. (researchsquare.com)

For instance, it is known that they can become bone, fat or cartilage cells. (analytica-world.com)

However, further studies are required to gain complete understanding of stem cell biology, which is fundamental for the development of successful cell-based therapies 1-3 . (bvsalud.org)

The G-CSF receptor is expressed on a variety of hematopoietic cells, including myeloid-committed progenitor cells, neutrophils, granulocytes, and monocytes. (stemcell.com)
CXCR4 is a G protein-linked seven transmembrane spanning receptor that has been identified as a receptor of stromal cell-derived factor-1 (SDF-1) for stem cells [ 22 - 24 ]. (hindawi.com)

At day 28, bony ankylosis showed increased biological process related to new bone formation, while fibrous ankylosis was characterized by a prolonged immune and inflammatory reaction. (medscimonit.com)

Hypoxia leads to the up-regulation of hypoxia-induced transcription factors (HIF)-a and HIF-2a, which are the master regulators of proangiogenic signals, mainly the vascular endothelial cell growth factors (VEGFs). (medscape.com)

We used a transplant model to determine whether CD341 cells migrate from the bone marrow to Ewing s sarcoma tumors and participate in the neovascularization process that supports tumor growth. (conicet.gov.ar)

Interestingly, contradictory data exist for transformation of bone marrow derived progenitor cells (BMPC) into new cardiomyocytes and alternative mechanisms as enhanced neovascularization, enhanced scar tissue formation due to augmented inflammatory response and decreased apoptosis have been suggested for the benefical effects of these cells on myocardial function after myocardial infarction (4). (escardio.org)
Endothelial injury triggers activation of the complement system-significantly through the lectin pathway-via altered cell-surface patterns on injured endothelial cells, initiating an inflammatory response [ 7 ]. (biomedcentral.com)
So we're going to go through its inflammatory modulating effects of what's called BMPs, which I'm going to refer to pretty frequently throughout the presentation, that's called bone morphogenetic proteins. (chiroeco.com)

The bone marrow stromal cell (BMSC) population, which makes up a large part of the hematopoietic microenvironment, encompasses a variety of adherent cell types. (techscience.com)

Aberrant high expression of B lymphocyte chemokine (BLC/CXCL13) by C11b + CD11c + dendritic cells in murine lupus and preferential chemotaxis of B1 cells towards BLC. (southernbiotech.com)

In the bone field we study cell based therapies using hypertrophic bone marrow or adipose derived MSC and iPS derived MSC. (icgeb.org)
