Background Adipose tissue mesenchymal stem cells (AT-MSCs) are suitable choices in treatment of liver associated diseases. Dimethyl Sulfoxide (DMSO) is an amphipathic molecule with potential of delivering both lipophilic and hydrophilic agents into cells. Few protocols used DMSO for induction of AT-MSCs towards hepatocyte like cells but the effect of DMSO on hepatogenic differentiation were no...

Background Recently, the clinical use of low power lasers has increased, and it is said that wound healing is accelerated by their irradiation. The aim of this study was evaluation of the effect of platelet-rich plasma on proliferation and differentiation of human dental pulp stem cells with or without Ga-Al-As laser. Methods: In this experimental study, human lower third molar dental pulp c...

Introduction: Chemokine receptors are found on the surface of stem cells. There have been 19 distinct chemokine receptors described in mammals. Chemokines are major players in migration and homing. Therefore, changes in their levels or function can help us to increase the migratory potential of these cells. Valproic acid differs in structure from other drugs in common use. The way in which Va...

Introduction: Adult stem cells are the group of cells which conserve their nature in tissues and organs among other cells. In recent years, the researchers reported the existence of stem cells on the Bulge of hair follicles near to the smooth muscle. It is possible to differentiate these stem cells to neural cells by induction of Shh, FGF, and RA factors. Because of existence of these factors ...

The old wishes of people were to regenerate lost tissues of periodontium that this fact is achieved by gen and cell therapy .Periodontal disease is a chronic inflammation around the tooth by microbes that causes destruction of supporting structure of tissue of tooth such as alveolar bone, cementum and periodontal ligament. For treatment of periodontal diseases we can use the biomaterials which ...

We present the results of a combined experimental and theoretical investigation of the vertical impact of a hydrophobic sphere with a water surface. Particular attention is given to characterizing the shape of the resulting air cavity in the low Bond number limit. A theoretical model is developed to describe the evolution of the cavity shape, and the pinch-off time is deduced for each of the th...

Glucose transporter 4 (GLUT4) is the major insulin-responsible glucose transporter expressed in muscle and adipose tissue and plays an important role in whole body glucose homeostasis. In the basal state, GLUT4 is sequestrated in several intracellular compartments, one of which has come to be known as insulin-responsive compartment (IRC). The IRC is a tissue specific compartment that is a targe...

Email of the presenting author: [email protected] Environmental scanning electron microscopy (ESEM) is an established method to investigate uncoated insulators, organic or biological samples in their original state. The presence of the imaging gas inside the specimen chamber is responsible for the secondary electron (SE) detection caused by gas amplification and the generated ...

Email of the presenting author: [email protected] After the first report of the production of an electron vortex beam, an electron traveling in free space with orbital angular momentum (OAM) [1], electron vortex beams have been attracting a great attention owing to the unique physical property and application to a new microscopy in materials science [2]. In the present paper, we show t...
