Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model. Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from ...

To investigate the effects of the conditioned medium on regulation of hematopoietic stem cells, serial volumes of monocyte-conditioned medium were added to the culture systems of CFUE and CFUC. Small volumes of the conditioned medium possessed stimulatory activity and large volumes inhibitory activity for both CFUE and CFUC. These findings suggest that the monocyte-conditioned medium regulates ...

Background and Aims: It has been proven that human mesenchymal stem cells (MSCs) conditioned medium (hMSCs-CM) can influence human embryonic stem cells (hESCs) chondrogenic differentiation. In this study, we hypothesized that conditioned medium (CM) from hESCs-derived MSCs in a sequential 3D-2D culture system could facilitate the induction of chondrogenesis in hESCs. Materials and Methods: CM ...

Background: Dental Pulp Stem Cells (DPSCs) are multipotent mesenchymal stem cells. DPSCs can renew themselves and differentiate into various cell types such as adipocytes, osteocytes, neurons, etc. DPSCs possess immunomodulatory properties and can inhibit peripheral blood mononuclear cell (PBMC) proliferation. Recent studies showed that conditioned-medium mesenchymal stem cells also had immunos...

A previous report has shown a deficiency of a cholinergic differentiating factor in spent culture media in which Alzheimer's disease (AD) patient fibroblasts were grown (Kessler, 1987). We used a similar approach to investigate whether AD fibroblast-conditioned medium demonstrated central nervous system (CNS) neuronal growth sustaining properties. For these investigations we used cultured fetal...

Anticoagulant properties of culture medium conditioned by human umbilical vein endothelial cells were investigated. In the presence of conditioned medium, both prothrombin time and activated partial thromboplastin time of normal plasma were prolonged by 4 and 10 seconds respectively compared with those in the presence of nonconditioned medium. The prologation of coagulation time was not affecte...

Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...

Background: Non-alcoholic fatty liver disease (NAFLD) constitutes a global pandemic. An intricate network among cytokines and lipids possesses a central role in NAFLD pathogenesis. Red blood cells comprise an important source of both cytokines and signaling lipids and have an important role in molecular crosstalk during immunometabolic deregulation. However, their role in NAFLD has not been tho...

Previous studies suggested that arterial smooth muscle cells (SMC) may be involved in regulating the growth of capillaries into atherosclerotic plaques. In the present study, we determined the effect of SMC products on porcine aortic endothelial cell (EC) replication in vitro. Quiescent or slowly growing EC in medium without endothelial cell growth factor (ECGF) were stimulated to proliferate i...

Heart cell-conditioned medium supports extensive neurite outgrowth from dissociated parasympathetic neurons of the chicken embryo ciliary ganglion. We have shown previously that neurite outgrowth in this system depends on the deposition of a substratum-conditioning factor from conditioned medium onto the polyornithine culture substratum. However, in the presence of only the substratum-bound mat...
