Abstract Mesenchymal stem cells (MSCs) are ideal candidates for treating many cardiovascular diseases. MSCs can modify the internal cardiac microenvironment to facilitate their immunomodulatory and differentiation abilities, which are essential to restore heart function. MSCs can be easily isolated from different sources, including bone marrow, adipose tissues, umbilical cord, and dental pulp. MSCs from various sources differ in their regenerative and therapeutic abilities for cardiovascular disorders. In this review, we will summarize the therapeutic potential of each MSC source for heart diseases and highlight the possible molecular mechanisms of each source to restore cardiac function. More >

Abstract Objective: This study aimed to investigate the potential of human umbilical cord mesenchymal stem cell (hucMSC)-derived exosomes (hucMSC-Exos) in inhibiting hypoxia-induced cell hyper proliferation and overexpression of vascular endothelial growth factor A (VEGF-A) in immature human fetal retinal microvascular endothelial cells (hfRMECs). Methods: Exosomes were isolated from hucMSCs using cryogenic ultracentrifugation and characterized through various techniques, including transmission electron microscopy, nanoparticle tracking analysis, bicinchoninic acid assays, and western blotting. The hfRMECs were identified using von Willebrand factor (vWF) co-staining and divided into four groups: a control group cultured under normoxic condition, a hypoxic model group, a hypoxic… More > Graphic Abstract

Abstract Human Umbilical Cord Mesenchymal Stem Cells (hUCMSCs) were subjected to in vitro osteogenic differentiation using a novel combination of signaling molecules including BMP-2 and purmorphamine. Differentiation outcomes were assessed by calcein staining and by microscopic examination of the cytoskeleton. Calcein staining showed appreciable degree of calcium mineralization in cell culture, and changes in the morphological attributes of differentiating cells were observed vis-a-vis the actin cytoskeleton. Finally, positive calcein staining, altered cytoskeletal profile, and stress fiber formation in treated cells demonstrated, for the first time, a potentially synergistic interplay between BMP-2 and the hedgehog agonist, purmorphamine.
