While paralysis is widely appreciated to impact the quality-of-life after spinal cord injuries (SCIs), neuropathic chronic pain may also occur in many cases. In this study, we investigated whether human umbilical cord-derived mesenchymal stromal cells (hUCMSCs) possess the therapeutic potential to reduce neuropathic pain following SCI in rats. Spinal cord hemitransection, which was used as a ra...

BACKGROUND Mesenchymal stem cells (MSCs) promote tumor growth by differentiating into carcinoma-associated fibroblasts (CAFs) and composing the tumor microenvironment. However, the mechanisms responsible for the transition of MSCs to CAFs are not well understood. Exosomes regulate cellular activities by mediating cell-cell communication. In this study, we aimed to investigate whether cancer cel...

The aim of this study was to investigate whether the chromosomes of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) change following in vitro culture for several generations. In the present study, umbilical cords from two healthy infants following cesarean delivery were collected aseptically and hUCMSCs were isolated by digestion with collagenase and trypsin, and then cultured in ...

The present study aimed to investigate the effects of lentiviral infection of human umbilical cord mesenchymal stem cells (hUCMSCs) on the expression of octamer transcription factor 4 (Oct4). hUCMSCs were infected with lentivirus carrying the green fluorescent protein gene (GFP) at different multiplicities of infection (MOI), and the optimal MOI was determined by flow cytometry; the proliferati...

Mesenchymal stem cells (MSCs) have exhibited therapeutic effects in multiple animal models so that are promising liver substitute for transplantation treatment of end-stage liver diseases. However, it has been shown that over-manipulation of these cells increased their tumorigenic potential, and that reducing the in vitro culture time could minimize the risk. In this study, we used a D-galactos...

Cell sources and tissue integration between cartilage and bone regions are critical to successful osteochondral regeneration. In this study, human umbilical cord mesenchymal stromal cells (hUCMSCs), derived from Wharton's jelly, were introduced to the field of osteochondral tissue engineering and a new strategy for osteochondral integration was developed by sandwiching a layer of cells between ...

OBJECTIVE This study aimed to compare the therapeutic efficacy of transplantation of human umbilical cord mesenchymal stem cells (hUCMSC) in different routes in acute hepatic failure (ALF) in rats. METHODS hUCMSCs were isolated and identified by detection of surface antigens via flow cytometry. In T group and H group, ALF rats received hUCMSC transplantation through the tail vein and intrahep...

Mesenchymal stem cells (MSCs) are mesoderm-derived cells that are considered a good source of somatic cells for treatment of many degenerative diseases. Previous studies have reported the differentiation of mesodermal MSCs into endodermal and ectodermal cell types beyond their embryonic lineages, including hepatocytes and neurons. However, the molecular pathways responsible for the direct or in...

BACKGROUND AND OBJECTIVES The purpose of this first of its kind study was to analyse the growth, development and attachment of cultured human umbilical cord stem cells alone or supplemented with basic Fibroblast Growth Factor (bFGF) on both healthy and periodontally diseased tooth surfaces in vitro. METHODS Four groups of 12 root surface scaffolds each were classified as Group I- healthy root...

Hydroxyapatite-tricalcium phosphate (HA-TCP) scaffold is a three-dimensional structure used to support bone regeneration. Ideally, the should be biocompatible, biodegradable, and non-toxic. The tissue engineering technique uses combined stem cell repair defect. To prove non-toxic properties of scaffold, cytotoxicity test needed for human umbilical cord mesenchymal (HUCMSCs). In this study, 27 s...
