Although the bone marrow (BM) microenvironment is the main inducer niche of early B lymphopoiesis during the adult life, other extramedullar microenvironments, such as the liver, may also have potential for supporting B-cell development. Previously, we reported that murine liver sinusoidal endothelial cells (LSECs) support in vitro and in vivo hematopoietic(More)
Today's high-end Gouraud renderers produce nicely textured scenes by mapping two-dimensional images onto modeled objects in real· time. We present a renderer which textures surfaces in the normal sense of the word using bump textures to simulate wrinkled or dimpled color­ ful surfaces. Using a simplified bump mapping method we first suc­ ceeded in designing(More)
Multipotent mesenchymal stromal cells (MSCs) from the human olfactory mucosa (OM) are cells that have been proposed as a niche for neural progenitors. OM-MSCs share phenotypic and functional properties with bone marrow (BM) MSCs, which constitute fundamental components of the hematopoietic niche. In this work, we investigated whether human OM-MSCs may(More)
Although there is evidence suggesting that statins may exert an endothelial protecting effect, recent in vitro data have shown that these compounds may induce endothelial cells (EC) apoptosis. We previously reported that the Fas-death receptor may induce apoptosis of the liver sinusoid endothelial cells (LSEC), and that TNF-alpha increases the(More)
Patients with mild cognitive impairment (MCI) or Alzheimer's disease (AD) might develop olfactory dysfunction that correlates with progression of disease. Alteration of olfactory neuroepithelium associated with MCI may be useful as predictor of cognitive decline. Biomarkers with higher sensitivity and specificity would allow to understand the biological(More)
There is evidence showing that mesenchymal stromal cells (MSC) may constitute a potential therapeutic strategy to induce bone regeneration. In this work, we investigate the capacity of autologous bone marrow (BM) MSC loaded on collagen microspheres (CM) and included into autologous platelet-rich plasma (PRP) clots (MSC/CM/PRP) to induce bone formation in(More)
Congenital pseudoarthrosis of the tibia (CPT) is an uncommon disease whose etiology and pathogenesis is unknown. Several evidences suggest that decreased osteogenic capacities, impaired local vascularization, and microenvironment alterations may play a role in the pathogenesis of CPT. Additionally, it is not clear if the pathogenesis of this disease is(More)
