Mesenchymal stem cells (MSCs) show high expression of PD-L1. Exosomes can transmit signals between tumor and stromal cells; however, the effect tumor-derived exosomes on cell signaling pathways is unclear. The PD-L1 in bone marrow mesenchymal (BMMSCs) was detected by western blot RT-PCR. effects gastric cancer line-derived BMMSC migration conditioned medium from educated BMMSCs were analyzed. O...

Background and Aims: Mesenchymal stem cells (MSCs) are a preferred cell source for the generation of hepatocyte-like cells in regenerative medicine. They can be isolated from different sources, including adipose tissues. The Raman spectroscopy approach was evaluated for quick and efficient identification of MSCs differentiation status and a broader perspective on cell differentiation. Material...

Articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. The scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. Cartilage tissue engineering requires 3 components: cells, scaffold, and environment. ...

Background: Hemophilia B is an X-linked hereditary disorder of blood coagulation system which is caused by factor IX (FIX) deficiency. Factor IX is a plasma glycoprotein that participates in the coagulation process leading to the generation of fibrin. Replacement of factor IX with plasma-derived or recombinant factor IX is the conventional treatment for hemophilia B to raise the factor IX le...

today, stem cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. the safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scient...

objective(s): nowadays much effort is being invested in order to diagnose the mechanisms involved in neural differentiation. by clarifying this, making desired neural cells in vitro and applying them into diverse neurological disorders suffered from neural cell malfunctions could be a feasible choice. thus, the present study assessed the capability of fetal brain extract (fbe) to induce rat bon...

in recent years, considerable advances have been made in the field of regenerative medicine. unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. it h...
