mesenchymal stem cells can be obtained from deferent tissues like adipose tissue, umbilical cord, placenta, skin, bone marrow, etc. these cells have regulatory effects on all types of immune cells such as dendritic cell, natural killers and lymphocytes. mesenchymal stem cells induce inhibitory phenotypes of antigen presenting cells (apcs) following their activity. they also change t cells pheno...

OBJECTIVE The multipotential nature of stem or progenitor cells apparently makes them the ideal choice for any cell therapy, but this as yet remains to be proven. This study (30 subjects) was designed to compare the potential to repair articular cartilage of chondrocytes taken from different regions in osteoarthritic cartilage with that of mesenchymal stem cells prepared from bone marrow of the...

Bone marrow hosts variety of tissues including hematopoietic lineage cells and mesenchymal stem cells (MSCs). The hematopoietic cells are the major source of the blood cells in the adult body which are regulated within the microenvironment of the stromal cells of the bone marrow [1]. MSCs are multipotent cells and can be differentiate into various cell lineage depend upon their environment and ...

according to significant improvements in the tissue engineering field over the past several years, lung tissue cells have recently attracted more attention due to the high prevalence and diversity in related diseases. however, selection of an appropriate cell type, screening of suitable conditions for growth and proliferation, as well as subsequent implantation into the body to repair and regen...

background: mesenchymal stem cells (msc) are a very promising transplantable stem cell source for a variety of cell replacement therapies. as the main source of msc is bone marrow (bm), most of studies have been done on bm-derived msc (bm-msc). umbilical cord (uc)-derived msc (uc-msc) which are recently introduced, is one of the good alternative source for these cells. the objective of this stu...

background :cell-based therapies can be used to treat neurological diseases and spinal cord injuries. the aim of this study was to assess the clinical outcome of bone marrow derived mononuclear cells (bm-mncs) transplantation in patients with spinal cord injuries.   method s: following a systematic review to detect clinical intervention studies, a meta-analysis was done for pooling data to esti...

Background: Adipose-derived stem cells (ADSC) could be an appealing alternative to bone marrow stem cells (BMSC) for engineering cell-based osteoinductive grafts. Meanwhile, prior studies have demonstrated that melatonin can stimulate osteogenic differentiation. Therefore, we assayed and compared the melatonin effect on osteogenic differentiation of BMSC with that of ADSC. Methods: Mesenchymal...

Reconstruction of the human auricle remains a challenge to plastic surgeons, and current approaches are not ideal. Tissue engineering provides a promising alternative. This study aims to evaluate the chondrogenic potential of bone marrow-derived mesenchymal stem cells on a novel, auricular-shaped polymer. The proposed polyhedral oligomeric silsesquioxane-modified poly(hexanolactone/carbonate)ur...

Bone marrow stromal cells are adult multipotent cells that represent an attractive tool in cellular therapy strategies. Several studies have reported that in vitro passaging of mesenchymal stem cells alters the functional and biological properties of those cells, leading to the accumulation of genetic aberrations. Recent studies described bone marrow stromal cells (BMSC) as mixed populations of...

BACKGROUND Stem cells, with their regeneration capacity, long-term viability, and differentiation characteristics, have indispensable biological properties. As described by Hauner and Grigoradis et al., mesenchymal stem cell originating from adipose or bone marrow can be differentiated into many tissues such as adipocyte, chondrocyte, myeloblast, and osteoblast. The aim of our study is to compa...
