Objective(s):Sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. This study was performed   to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rBMMSc) into osteogenic lineage. Materials and Methods: Isolated rBMMSc were grown in DMEM supplemented with 10% FBS. The cells were exposed to different concen...

introduction: the purpose of this study was to cultivate bone marrow cells from two different mouse strains (nmri and balb/c) and to examine them in terms of expression of ten surface antigens from primary culture to passage 3. material and methods: 6-8 weeks old either nmri or balb/c mice were sacrificed and their bone marrows were harvested and cultivated .two weeks after culture initiation, ...

human mesenchymal stem cells (hmscs), which also called mesenchymal stromal cells, are multipotent stem cell. human mscs typically are positive for the surface markers cd44, cd73, cd90, cd105, cd106, and also negative for hematopoietic markers cd34 and cd45.these cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

The purpose of this study was to determine the clinicopathological and immunohistochemical features of lipoma/fibrolipoma with rare occasions as osseous and/or chondroid differentiation in the oral cavity. Two cases of the tumors, who presented with a painless, relatively hard mass on the oral mucosa, were studied. These were consisted of a well-circumscribed mass of fatty tissue with chondroid...

Adipose differentiation is a complex process controlled by a network of transcription factors and co-regulators. We compared the global gene expression patterns of adipogenic and nonadipogenic clones of 3T3-F442A preadipocytes and identified the transcriptional cofactor, vestigial-like 3 (Vgll3), as an inhibitor of adipogenesis. Vgll3 expression is down-regulated during terminal adipocyte diffe...

Hyperlipidemia and marrow fat are associated with lowering bone density in vivo, suggesting that lipid contributes to bone loss. Using bone marrow-derived macrophages, we investigated the effect of saturated fatty acids (SFA) on osteoclastogenesis. The level of free fatty acids and adiposity in bone marrow was significantly elevated in obese mice. SFA increased osteoclast (OC) survival by preve...

Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...

to evaluate the effects of supplementation of tomato pomace (tp), canola, soybean and tallow oils on performance, carcass characteristics, and bone parameters of heat stressed broilers, 792 d-old arian broiler were divided to 36 pens. each dietary treatment had 4 replicate with 22 birds each. these factorial experiment (3*3) involved 3 kinds of canola, soybean and tallow oils and 3 levels of 0,...
