Resorbable, porous iron-manganese-hydroxyapatite biocomposites with suitable degradation rates for orthopedic applications are prepared using salt-leaching for the first time. These transient biomaterials have the potential to replace inert, permanent implants that can suffer from long-term complications, or have to be surgically removed, leaving an unfavorable void. Fe30Mn-10HA materials are newly developed to address inadequate resorption rates of degradable materials proposed for orthopedic environments in the past...

Therapy targeting mitochondria may provide novel ways to treat diabetes and its complications. Bone marrow-derived mesenchymal stem cells (MSCs), the peroxisome proliferator-activated receptor gamma (PPAR-γ) agonists and exendin-4; an analog of glucagon-like peptide-1 have shown cardioprotective properties in many cardiac injury models. So, we evaluated their effects in diabetic cardiomyopathy (DCM) in relation to mitochondrial dysfunction. This work included seven groups of adult male albino rats: the control group, the non-treated diabetic group, and the treated diabetic groups: one group was treated with MSCs only, the second with pioglitazone only, the third with MSCs and pioglitazone, the forth with exendin-4 only and the fifth with MSCs and exendin-4...

Dysfunction of salivary glands leads to several oral health problems, including dental caries, mastication and swallowing dysfunctions and multiple oral infections. Conventional treatments for such condition fell short of providing satisfying therapeutic results. Recent advances in organ regeneration therapy which utilize tissue stem cells to fabricate bioengineered 3D organ buds, have introduced a promising therapeutic tool for full functional organ regeneration. However, finding a sustainable and easily accessible cell source for such approaches is still challenging, especially in case of severely atrophied tissues such as irradiated salivary glands...

Mesenchymal stem cells derived from bone marrow (BM-MSCs) have multi-functional properties that have made them a promising therapeutic agent for many regenerative, anti-inflammatory, and auto-immune applications. Under chronic pathological conditions, however, BM-MSCs can become functionally compromised due to long term exposure to changes in the systemic and localized stem cell niche micro-environments. In addition to the fact that functionally compromised BM-MSCs may be therapeutically ineffective, the impairment of BM-MSCs is potentially a contributing factor to disease progression and the development of co-morbidities...

Vitamin K2 has been demonstrated to promote the osteogenic differentiation of mesenchymal stem cells; however, the mechanisms underlying this effect remain unclear. As microRNA (miR)‑133a has been identified as a negative regulator of osteogenic differentiation, the present study hypothesized that vitamin K2 promoted osteogenesis by inhibiting miR‑133a. Using human bone marrow stromal cells (hBMSCs) overexpressing miR‑133a, or a control, the expression levels of osteogenesis‑associated proteins, including runt‑related transcription factor 2, alkaline phosphatase and osteocalcin, were analyzed...

The aim of the present study was to explore the effects of co‑culturing bone marrow‑derived mesenchymal stem cells (BM-MSCs) cultured with hepatitis B virus (HBV)‑infected lymphocytes in vitro. BM‑MSCs and lymphocytes from Brown Norway rats were obtained from the bone marrow and spleen, respectively. Rats were divided into the following five experimental groups: Group 1, splenic lymphocytes (SLCs); group 2, HepG2.2.15 cells; group 3, BM‑MSCs + HepG2.2.15 cells; group 4, SLCs + HepG2.2.15 cells; and group 5, SLCs + BM‑MSCs + HepG2...

The occurrence of pelvic organ prolapse (POP) is closely associated with alterations in the extracellular matrix proteins of the supporting ligament. Bone marrow mesenchymal stem cells (BMSCs) have the potential to differentiate into a variety of cell types, including osteoblasts, chondroblasts and adipocytes. Therefore, BMSCs have the potential to improve the clinical outcomes of POP. Tenascin‑C is a large glycoprotein that is present in the ECM and is involved in morphogenetic movements, and tissue patterning and repair...

Human bone marrow stromal cells (BMSCs, also known as bone marrow-derived mesenchymal stem cells) are manufactured using many different methods, but little is known about the spectrum of manufacturing methods used and their effects on BMSC characteristics and function. Seven centers using, and one developing, Good Manufacturing Practices (GMP) processes were surveyed as to their production methods. Among the seven centers, all used marrow aspirates as the starting material, but no two centers used the same manufacturing methods...

<p>Biodistribution and fate of transplanted stem cells via longitudinal monitoring has been successfully achievedin the last decade using optical imaging. However, sensitive longitudinal imaging of transplanted stem cells in deep tissue like the brain remains challenging not only due to low light penetration but because of other factors such as low or inferior expression levels of optical reporters in stem cells and stem cell death after transplantation. Here we describe an optimized imaging protocol for sensitive long term monitoring of human bone marrow derived mesenchymal stem cells (hMSCs) expressing a novel bioluminescent/near infrared fluorescent (NIRF) fusion reporter transplanted in mouse brain cortex...

Spinal cord injury (SCI) is a widely disabling condition, constraining those affected by it to wheelchairs and requiring intense daily care and assistance. Cell replacement therapies, targeting regeneration of cells in the injured cord, are currently gaining momentum in the field of SCI research. Previous studies indicate that mesenchymal stem cells (MSCs) can reduce functional deficits through immunomodulation and production of trophic factors in a variety of neurological disorders. The present study assessed the efficacy of transplanted bone marrow-derived MSCs at different concentrations and locations for promoting functional recovery following SCI...

BACKGROUND: In view of the current interest in exploring the clinical use of mesenchymal stem cells (MSCs) from different sources, we performed a side-by-side comparison of the biological properties of MSCs isolated from the Wharton's jelly (WJ), the most abundant MSC source in umbilical cord, with bone marrow (BM)-MSCs, the most extensively studied MSC population. METHODS: MSCs were isolated and expanded from BM aspirates of hematologically healthy donors (n = 18) and from the WJ of full-term neonates (n = 18)...

BACKGROUND: Three-dimensional cultured clumps of a mesenchymal stem cell (MSC)/extracellular matrix (ECM) complex (C-MSC) consists of cells and self-produced ECM. C-MSC can regulate the cellular function in vitro and induce successful bone regeneration using ECM as a cell scaffold. Potentiating the immunomodulatory capacity of C-MSCs, which can ameliorate the allo-specific immune response, may be helpful in developing beneficial "off-the-shelf" cell therapy for tissue regeneration. It is well reported that interferon (IFN)-γ stimulates the immunosuppressive properties of MSC via upregulation of the immunomodulatory enzyme IDO...

Background and Objectives: Neuroinflammation is involved in the pathogenesis of neurodegenerative disorders. Conditioned medium (CM) derived from bone marrow mesenchymal stem cells (MSCs) revealed substantial benefits due to its rich content of trophic factors. Salidroside (Sal), extracted from Rhodiola rosea, is known for its anti-inflammatory and neuroprotective effects. This study was designed to investigate the effect of Sal pretreated CM (CM-Sal) derived from bone marrow MSCs in lipopolysaccharide (LPS) induced neuroinflammation...

Mesenchymal stem cells (MSCs) have been widely used in regenerative medicine and cellular therapy due to their multi-lineage differentiation potential and immunomodulatory function. The applicability of MSCs also depends on their cellular sources and in vivo functions. Here in this study, we systematically compared the morphologic characteristics, immunophenotypes and the adipogenic differentiation of MSCs derived from umbilical cord (UC), adipose tissue (Ad) and bone marrow (BM). We found that the three tissues-derived MSCs displayed decreased adipogenic capacity in the order: Ad-MSC > BM-MSC > UC-MSC, and no morphologic and immunophenotypic differences were observed...

A predominant challenge in developing curative leukemia therapy is interactions of leukemic cells with the bone marrow stromal microenvironment. We aimed to investigate the role of stromal cells, such as bone marrow mesenchymal stromal cells (BMSCs) and osteoblasts (OBs), in curcumin (CUR) and daunorubicin (DNR) induced apoptosis of acute myeloid leukemia (AML) cells. We used KG1 and U937 as leukemia cell line models and treated them with CUR and DNR. The cells were then co-cultured with BMSCs or a combination of BMSCs and OBs as feeders...

Cancer survivors after radiotherapy may suffer a variety of bone‑related adverse side effects, including radioactive osteoporosis and fractures. Localized irradiation is a common treatment modality for malignancies. Recently, a series of reactions and injuries called indirect effects (remote changes in bone when other parts of the body are irradiated) have been reported on the indirect irradiated area of bone tissue after radiotherapy. To address this issue, we developed a rat localized irradiation model...

Damage of retinal ganglion cells (RGCs) is the major consequence of glaucoma and regeneration of RGCs is extremely difficult once the damage has occurred. Retinal stem cells (RSCs) are considered an ideal choice for RGC regeneration. Pigmented cells from the ciliary margin (PCMs) have great retinal differentiation potential and may be an ideal RSC candidate. However, the ciliary margin is too small, so the number of cells that can be obtained is limited. Bone marrow‑derived mesenchymal stem cells (BMMSCs) are another type of stem cell that have been previously investigated for RGC regeneration...

Recently, we identified the scrapie responsive gene 1 (SCRG1) secreted from mesenchymal stem cells (MSCs) and its receptor bone marrow stromal cell antigen 1 (BST1) as positive regulators of stem cell qualities such as self‑renewal, migration abilities, and osteogenic differentiation potential. Here, we examined the effect of the paracrine activity of SCRG1 in macrophages. The mouse macrophage‑like cell line Raw264.7 expressed BST1/β1 or BST1/β2 integrin as possible SCRG1 receptors. Unexpectedly, recombinant SCRG1 did not enhance cell proliferation, migration, or adhesion in these macrophages...

Mesenchymal stem cells (MSC) stand as a promising tool in regenerative medicine because of their high therapeutic potential in treatment of degenerative, metabolic and other types of diseases. The cellular therapies involving MSCs include their isolation mainly from the bone marrow, adipose tissue or umbilical cord and in vitro expansion for further autologous or allogeneic transplantation. Recent studies revealed, that bioactive compounds, naturally occurring in seaweeds, herbs, fruits and vegetables, possess the ability to modulate self-renewal and differentiation potential of adult stem cells, targeting a broad range of intracellular signal transduction pathways...
