Structural and ultrastructural evaluation of the aortic wall after transplantation of bone marrow-derived cells (BMCs) in a model for atherosclerosis.

Stem cells are characterized by their ability to differentiate into multiple cell lineages and display the paracrine effect. The aim of this work was to evaluate the effect of therapy with bone marrow-derived cells (BMCs) on glucose, lipid metabolism, and aortic wall remodeling in mice through the administration of a high-fat diet and subsequent BMCs transplantation. C57BL/6 mice were fed a control diet (CO group) or an atherogenic diet (AT group).

Remodeling of the thoracic aorta after bone marrow cell transplantation.

Stem cells are characterized by their ability to differentiate into multiple cell lineages and display the paracrine effect. The aim of this work was to evaluate the effect of therapy with bone marrow cells (BMCs) on blood glucose, lipid metabolism and aortic wall remodeling in mice through the administration of a high fat diet and subsequent BMCs transplantation. C57BL/6 mice were fed a control diet (CO group) or an atherogenic diet (AT group).

Exercise training enhances elastin, fibrillin and nitric oxide in the aorta wall of spontaneously hypertensive rats.

This work aimed to analyze the effect of low-intensity exercise training on ultrastructural and molecular aortic remodeling. Male Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR) were allocated into four groups: sedentary WKY (SED-WKY), exercised WKY (EX-WKY, 1 h/day, 5 days/week treadmill exercise training), sedentary SHR (SED-SHR), and exercised SHR (EX-SHR). EX-SHR showed blood pressure reduction of 26% in comparison to SED-SHR after 1 month of exercise (P<0.
