We utilized two separate techniques, human Umbilical Cord Blood Stem Cells (hUCBC) and chitosan hydrogels, to limit acute myocardial infarction size and LV remodeling. Human Umbilical Cord Blood Mononuclear Cells (hUCBC), contain hematopoietic and mesenchymal stem cells. Chitosan is a polysaccharide....

The development of cell lines with high cell density, controlled proliferation, apoptosisresistance, and easy adaptation into cultures of serum free media is essential for the success of tissue engineering strategies....

Hypoxia is one of the factors that trigger the release of inflammatory and vasculogenic cytokines during tissue regeneration. Mesenchymal stem cells (MSC) with and without endothelial cells (EC) were cultured in vitro in normoxic and hypoxic environments. The mRNA expression of inflammatory and vasculogenic cytokines were evaluated at 1, 12, 24 and 48 hours. After 48 hours of incubation in normoxic and hypoxic conditions, supernatants termed as conditioned medium (CM) from each group were collec...
