Fotografía correspondiente a la placa de cultivo coloreada con rojo de alizarina de cultivos de células estromales humanas tratadas por 33 días con C: medio control (DMEM:HAM F12, 1:1 + 10 mM β-glicerol fosfato y 50 mg/ml ácido ascórbico); DXM: medio control +dexametasona 10 -7 M; BM: medio control +0,20 mg/ml extracto acuoso foliar de B. megalandra; G: medio control + 10 -4 M genisteína. En la fila inferior se muestran las micrografías obtenidas mediante microscopia óptica convencional, donde se observan en detalle la presencia o no de nódulos de mineralización.

RESUMEN Estudios epidemiológicos demuestran que dietas ricas en flavonoides previenen afecciones relacionadas con la menopausia tales como la osteoporosis, debido a que poseen una estructura similar al 17β-estradiol. Por ello pueden ser empleados como sustitutos terapéuticos y de allí su nombre más conocido: fitoestrógenos. En Venezuela, se ha repo...

Bone mass is determined by the balance between bone formation, carried out by mesenchymal stem cell-derived osteoblasts, and bone resorption, carried out by monocyte-derived osteoclasts. Here we investigated the potential roles of p38 MAPKs, which are activated by growth factors and cytokines including RANKL and BMPs, in osteoclastogenesis and bone...
In this study, we identified a CD105+CD90.1−CD133−CD55− (CD133−CD55−) population in the fetal skeletal element that can generate bone and bone marrow. Besides osteoblasts and chondrocytes, the CD133−CD55− common progenitors can give rise to marrow reticular stromal cells and perivascular mesenchymal progenitors suggesting they function as the fetal...
Similar to other adult tissue stem/progenitor cells, bone marrow mesenchymal stem/stromal cells (BM MSCs) exhibit heterogeneity at the phenotypic level and in terms of proliferation and differentiation potential. In this study such a heterogeneity was reflected by the CD200 protein. We thus characterized CD200(pos) cells sorted from whole BM MSC cu...
