Multicellular spheroids are an established system for three-dimensional cell culture. Spheroids are typically generated using hanging drop or non-adherent culture; however, an emerging technique is to use magnetic levitation. Herein, mesenchymal stem cell spheroids were generated using magnetic nanoparticles and subsequently cultured within a type I collagen gel, with a view towards developing ...

the stem cells can be considered as the miracle of creation, because, they are a major reservoir of the bioactive factors, molecules and cells. these reservoir cells play a major role in development and growth of the tissues and organs. regardless of the differences in differentiation capacity of embryonic and adult stem cells, both the cells are rich sources of stem cells with therapeutic appl...

OBJECTIVE To evaluate the effect of low-level laser irradiation on the proliferation and possible nuclear morphological changes of mouse mesenchymal stem cells. METHODS Mesenchymal stem cells derived from bone marrow and adipose tissue were submitted to two applications (T0 and T48 hours) of low-level laser irradiation (660 nm; doses of 0.5 and 1.0 J/cm2). The trypan blue assay was used to ev...

Imbalance in immune responses plays an indispensable role pathogenesis and development of multiple sclerosis (MS), as a neurodegenerative disorder. Current treatments are not always successful preventing MS treating the disease. Stem cell-based cell therapy has provided new window for disorders. cells can regulate system improve axonal remyelination. They be isolated from different origins such...

Mesenchymal stem cells (MSCs) - usually obtained from bone marrow - often require expansion culture. Our protocol uses clinical grade urokinase to degrade clots in the bone marrow and release MSCs for further use. This protocol provides a rapid and inexpensive alternative to bone marrow resampling. Bone marrow is a major source of MSCs, which are interesting for tissue engineering and autologou...

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...

OBJECTIVE To evaluate the effects of the petroleum ether extract of Cissus quadrangularis on the proliferation rate of bone marrow mesenchymal stem cells, the differentiation of marrow mesenchymal stem cells into osteoblasts (osteoblastogenesis) and extracellular matrix calcification. This study also aimed to determine the additive effect of osteogenic media and Cissus quadrangularis on prolife...

PURPOSE To evaluate in vitro ability the of three different biomaterials - purified hydroxyapatite, demineralized bone matrix and castor oil-based polyurethane - as biocompatible 3D scaffolds for canine bone marrow mesenchymal stem cell (MSC) intending bone tissue engineering. METHODS MSCs were isolated from canine bone marrow, characterized and cultivated for seven days with the biomaterials...
