Tumor antigens is at the core of cancer immunotherapy, however, the ideal antigen selection is difficult especially in poorly immunogenic tumors. In this study, we designed a strategy to modify hepatocellular carcinoma (HCC) cells by surface expressing anti-CD3scfv within the tumor site strictly, which depended on the E1A-engineered human umbilical cord mesenchymal stem cells (HUMSC.E1A) delivery system. Subsequently, membrane-bound anti-CD3scfv actived the lymphocytes which lysed HCC cells bypassing the expression of antigens or MHC restriction...

BACKGROUND/AIMS: Mesenchymal stem cells (MSCs) play an important role in regulating angiogenesis and immune balance. Abnormal proliferation and function of MSCs were reported at maternal fetal interface in patients with pre-eclampsia (PE). Micro-RNA-495 was known to be upregulated in the MSCs derived from patients with PE. However, it is not clear whether the up-regulated miR-495 is related to the pathogenesis of PE. METHODS: We analyzed the expression of miR-495 in MSCs and umbilical cords derived from healthy pregnancies (NC) and PE, then we upregulated or downregulated the expression of miR-495 in MSCs derived from NC and tested the proliferation, apoptosis, migration, invasion, tube formation and senescence...

Activated platelet-rich plasma (PRP) has been studied as a replacement for fetal bovine serum (FBS) in stem cell culture. However, current methods are time-consuming or require addition of exogenous substances to activate PRP, which have disadvantages in clinical applications. In this study, we developed a new method for PRP activation using a bead mill homogenizer and compared it with previous methods of PRP activation. PRP was prepared via a two-step centrifugation process and activated via calcium (Ca-PRP), freeze-thaw cycles (FT-PRP), or bead mill homogenizer processing (BM-PRP)...

Cardiotrophin-1 (CT1) plays an important role in the differentiation, development, and survival of neural stem cells. In this study, we analyzed its effects on the stimulation of human umbilical cord blood-derived mesenchymal stem cells in terms of their potential to differentiate into neuron-like cells, their survival characteristics, and the molecular mechanisms involved. The treatment of cells with neural induction medium (NIM) and CT1 generated more cells that were neuron-like and produced stronger expression of neural-lineage markers than cells treated with NIM and without CT1...

OBJECTIVE: Musculodegenerative diseases threaten the life of many patients in the world. Since drug administration is not efficient in regeneration of damaged tissues, stem cell therapy is considered as a good strategy to restore the lost cells. Since the efficiency of myogenic differentiation potential of human Chorion- derived Mesenchymal Stem Cells (C-MSCs) has not been addressed so far; we set out to evaluate myogenic differentiation property of these cells in comparison with Umbilical Cord Blood- derived Mesenchymal Stem Cells (UCB-MSCs) in the presence of 5-azacytidine...

Induced osteogenesis of mesenchymal stem cells (MSCs) may provide an important tool for bone injuries treatment. Human umbilical cord and adipose tissue are routinely discarded as clinical waste and may be used as noncontroversial MSCs sources. It still remains to be verified which source of MSCs is the most suitable for bone regeneration. The aim of this research was to investigate the osteogenic potential of human MSCs derived from adipose tissue (AT-MSCs) and Wharton's jelly of the human umbilical cord (WJ-MSCs) differentiated under the same conditions...

Background: Adult mesenchymal stem cells (MSCs) were first isolated from bone marrow by Friedenstein in 1976. These cells were clonogenic, non-haematopoietic, and able to replicate extensively in vitro. The fields of regenerative medicine and tissue engineering have grown dramatically since their inception. In the decades since, MSCs have been identified from mesoderm-, endoderm- and ectoderm-derived tissues. In light of our ageing population, the need for effective cell-based therapies for tissue repair and regeneration is ever-expanding...

Previous studies have reported that the conditioned medium (CM) of bone marrow-mesenchymal stem cells (BM-MSCs) stimulate the migration and proliferation of cell types involved in the wound healing process. However, these studies only show MSC-CM effects that were obtained using a two-dimensional (2D) culture. Recently, a three-dimensional (3D) culture has been considered to be a more physiologically appropriate system than the 2D culture. In addition, it has been shown that the procurement of BM-MSC is invasive, and other sources of MSC are thus being explored...
