Patients with human immunodeficiency virus-1 (HIV-1) infection often present with hematopoietic failure. As the important hematopoietic support cells in the bone marrow (BM), the bone marrow mesenchymal stem cells (BMSCs) can be impacted by HIV proteins that are released by infected cells within BM. In this study, we tested whether HIV protein p55-gag could induce senescence of BMSCs and reduce their capacity to support expansion of hematopoietic stem cells in vitro. BMSCs were chronically treated with p55-gag (BMSCgag ) for up to 20 days, and their proliferative activity and senescence makers were compared to nontreated cells (BMSCcon )...

Cardiomyopathy induced by doxorubicin (DOX) was recognized at an early stage and also several years after drug administration. Mesenchymal stem cells (MSCs) have many properties that make them suitable for preventive and/ or regenerative therapies. In this study, we evaluated the effect of MSCs in the functional and the structural improvement of DOX-induced cardiomyopathy in rats. Ninety adult male albino rats were randomly divided into three equal groups of thirty rats each: Group I (control): rats received normal saline...

Islets from xeno-sources and islet like clusters derived from autologus stem cells have emerged as alternatives to cadaveric pancreas used for treatment of type 1 diabetes. However, the immuno-isolation of these islets from the host immune system suffers from the issue of biocompatibility and hypoxia. To overcome the issues of immunobarrier biocompatibility, we developed a Polysulfone (Psf)/TPGS composite hollow fiber membrane (HFM) using a hollow fiber spinning pilot plant specially developed for this purpose...

Recent approaches in tissue regeneration focus on combining innovative achievements of stem cell biology and biomaterial sciences to develop novel therapeutic strategies for patients. Growing recent evidence indicates that mesenchymal stem cells harvested from human umbilical cord Wharton's jelly (hUC-MSCs) are a new valuable source of cells for autologous as well as allogeneic therapies in humans. hUC-MSCs are multipotent, highly proliferating cells with prominent immunoregulatory activity. In this study, we evaluated the impact of widely used FDA approved poly(α-esters) including polylactide (PLA) and polycaprolactone (PCL) on selected biological properties of hUC-MSCs in vitro...

Hybrid tissue engineered (HTE) scaffolds constituting polymeric nanofibers and biological tissues have attractive bio-mechanical properties. However, they suffer from small pore size due to dense overlapping nanofibers resulting in poor cellular infiltration. In this study, using nanosecond (ns) laser, we fabricated micro-scale features on Polycaprolactone (PCL)-Chitosan (CH) nanofiber layered bovine pericardium based Bio-Hybrid scaffold to achieve enhanced cellular adhesion and infiltration. The laser energy parameters such as fluence of 25J/cm(2), 0...

Bone marrow derived mesenchymal stem cells (MSCs) play a critical role in immune modulation. However, immunomodulatory function of whole human umbilical cord derived mesenchymal stem cells (UC-MSCs) remains unclear. In this study, UC-MSCs were separated from whole umbilical cord using a single enzyme digestion. UC-MSCs (CD73(+), CD90(+), CD105(+), and CD34(-), CD45(-), HLA-DR(-)) were differentiated into adipocytes, osteocytes and chondrocytes in vitro under specific stimulatory environments. UC-MSCs suppressed umbilical cord blood lymphocyte proliferation stimulated by mitogen, and ELISA showed that the secretion of INF-γ was downregulated, and the secretion of IL-4 was upregulated, with CD8(+) T cells markedly decreased and CD4(+) T cells changed lightly...

Human umbilical cord-derived mesenchymal stem cells (hucMSCs) are suggested as a promising therapeutic tool in regenerative medicine, however, their efficacy requires improvement. Small molecules and drugs come up to be a convenient strategy in regulating stem cells fate and function. Here, we evaluated 3,3'-diindolylmethane (DIM), a natural small-molecule compound involved in the repairing effects of hucMSCs on a deep second-degree burn injury rat model. HucMSCs primed with 50 μM of DIM exhibited desirable repairing effects compared with untreated hucMSCs...

We are rapidly becoming an aging society, with the ongoing increase in challenges of the elderly. The age-related cognitive decline in accordance with aging society is of major importance in public health. Recent studies have proved the impacts of sex-steroid hormone on the brain; compliant with aging, menopause and decrease in estrogen have an effect on the occurrence and prevention of Alzheimer's disease. A new hypothesis states that Alzheimer's disease is a postmenopausal dementia, and is a negative form of estrogen deficiency...

The concept of Regenerative Medicine combined with Cell based Therapy and Tissue Engineering represents the fourth pillar of healthcare and provides a promising approach for the treatment of serious diseases. Recently, cell based therapies are focused on the use of mesenchymal stem/stromal cells (MSCs). Human MSCs, that represent a mesoderm derived population of progenitors, are easily expanded in culture. They are capable to differentiate into osteoblasts, chondrocytes, and adipocytes and exhibit the potential to repair or regenerate damaged tissues...

Objective. Human umbilical cord mesenchymal stem cells (hUC-MSCs) potentially differentiate to various types of cells including neuron-like cells. The natural polyphenol resveratrol benefits patients with many diseases including ischemic brain injury. We hypothesize that resveratrol induces differentiation of hUC-MSCs into neuron-like cells. Methods. Flow cytometry was used to determine the surface antigens in different stage of hUC-MSCs (P2, P5, and P10). Nestin, neuron-specific enolase (NSE), and glial fibrillary acidic protein (GFAP) were detected by immunocytochemistry, Western blotting, and real time RT-PCT...

Mitochondria are the central hubs for cellular bioenergetics and are crucial to cell survival. It is well accepted that compromised mitochondrial function is linked with hepatocytes injury and contribute to progression of liver diseases. Despite the therapeutic potential of mesenchymal stem cells (MSCs) transplantation on hepatic disorders have been extensively investigated, the effects of MSCs on mitochondrial function in liver injury models remain unknown. Here we investigated the effects of treatment with umbilical cord (UC) MSC in a rat model of D-Gal induced liver injury, characterized by organ damage, oxidative stress and mitochondrial dysfunction...

Spinal Cord Injury (SCI) is a serious devastating condition associated to the high chances of morbidity and mortality. It involves a primary and a secondary injury, former cause damages to both lower and upper motor neurones and disrupts sensory, motor and autonomic functions while the latter involves various stages of molecular plus cellular incidents which elaborate the original injury. In the treatment of SCI, stem cells possess a good therapeutic potential. Bone marrow, adipose tissue, placenta, amniotic fluid and umbilical cord are the good sources for mesenchymal stem cells...

Bone marrow (BM) aspirates, mobilized peripheral blood (PB) and umbilical cord blood (UCB) have developed as graft sources of hematopoietic stem and progenitor cells (HSPC) for stem cell transplantation and other cellular therapeutics. Individualized techniques are necessary to enhance graft HSPC yields and cell quality from each graft source. BM aspirates yield adequate CD34+cells but can result in relative delays in engraftment. Granulocyte-colony stimulating factor (G-CSF) primed bone marrow HSPC may facilitate faster engraftment while minimizing graft-versus-host disease (GVHD) in certain patient subsets...

The umbilical cord has become an increasingly used source of mesenchymal stromal cells for preclinical and, more recently, clinical studies. Despite the increased activity, several aspects of this cell population have been under-appreciated. Key issues are that consensus on the anatomical structures within the cord is lacking, and potentially different populations are identified as arising from a single source. To help address these points, we propose a histologically based nomenclature for cord structures and provide an analysis of their developmental origins and composition...

Effective therapeutic strategies for treating chronic spinal cord injury (SCI) are currently unavailable. Scar tissue in the lesion area is a main inhibitory factor for axonal regeneration and repair of chronic SCI. In this study, scar tissue was surgically resected from adult rats with 12-week chronic SCI, and then collagen scaffold (named NeuroRegen Scaffold [NRS]) and human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) were implanted into the resected cavity to repair chronic SCI. The results demonstrated that the locomotor function of rats was not affected by surgical scar resection, indicating its safety in treating chronic SCI...
