Mesenchymal stem cells (MSCs) curative effects on methotrexate (MTX)-induced kidney and liver injuries remain elusive. Therefore, rats were divided into five groups, rats received MTX orally (14 mg/kg) as a single dose/week for 2 weeks, groups 3 and 4 were injected once with 2 × 10(6) cells bone marrow MSCs and adipose-derived MSCs, respectively. The last group administered dexamethasone (DEX) (0.5 mg/kg, p.o) for 7 days. MTX caused marked increase in malondialdehyde and nitrite/nitrate concentrations...

BACKGROUND: Low birth weight (LBW) neonates have impaired kidney development that leaves them susceptible to kidney disease and hypertension during adulthood. The study here identifies events that blunt nephrogenesis and kidney development in the murine LBW neonate. METHODS: We examined survival, kidney development, GFR, gene expression, and cyto-/chemokines in the LBW offspring of malnourished (caloric and protein restricted) pregnant mice. RESULTS: Malnourished pregnant mothers gave birth to LBW neonates that had 40% reduced body weight and 54% decreased survival...

PURPOSE: RRx-001, a minimally toxic tumor-associated macrophage and neutrophil-repolarizing agent, is under investigation in Phase II clinical trials as a sensitizer/resensitizer to cisplatin and carboplatin. On the basis of anecdotal clinical observations of improved platinum tolerability following a priming period with RRx-001 as well as preclinical studies that have previously demonstrated radioprotection of intestinal stem cells and cardioprotection from doxorubicin, the in vivo cytoprotective potential of RRx-001 pretreatment against cisplatin-induced bone marrow suppression and renal toxicity was investigated...

Osteoblasts, originating from mesenchymal cells, make the receptor activator of the nuclear factor kappa B ligand (RANKL) and osteoprotegerin (OPG) in order to control differentiation of activated osteoclasts, originating from hematopoietic stem cells. When the RANKL binds to the RANK of the pre-osteoclasts or mature osteoclasts, bone resorption increases. On the contrary, when OPG binds to the RANK, bone resorption decreases. Denosumab (AMG 162), like OPG (a decoy receptor), binds to the RANKL, and reduces binding between the RANK and the RANKL resulting in inhibition of osteoclastogenesis and reduction of bone resorption...

Preconditioning of mesenchymal stem cells (MSCs) with melatonin (MT) has shown promising results in animal models of myocardial infarction, renal ischemia and cerebral ischemia. Here, we use this strategy in the liver fibrosis induced by CCl4. There were five groups: normal, CCl4, CCl4 + vehicle, CCl4 + BMMSCs and CCl4 + MT-bone marrow (BM)-derived MSCs (MT-BMMSCs). CCl4 was injected twice weekly for 8 weeks and treatment either with cells or vehicle was performed at the beginning of week 5 with a single dose...

BACKGROUND: Interleukin-10 secreting B-cells are a major subset of B-regulatory cells (B-regs), commonly recognized as CD19(+)/38(hi)/24(hi)/IL10(+). They carry out immunomodulation by release of specific cytokines and/or cell-to-cell contact. We have generated B-regs in-vitro from donor adipose tissue derived mesenchymal stem cells (AD-MSC) and renal allograft recipient (RAR) peripheral blood mononuclear cells (PBMC) for potential cell therapy. MATERIAL AND METHODS: Mononuclear cells separated by density gradient centrifugation from 50 ml anti-coagulated blood of 15-RAR and respective donors were analysed for baseline B-regs using appropriate antibodies...

The collecting duct of the mammalian kidney is important for the regulation of extracellular volume, osmolarity, and pH. There are two major structurally and functionally distinct cell types: principal cells and intercalated cells. The former regulates Na(+) and water homeostasis, while the latter participates in acid-base homeostasis. In vivo lineage tracing using Cre recombinase or its derivatives such as CreGFP and CreER(T2) is a powerful new technique to identify stem/progenitor cells in their native environment and to decipher the origins of the tissue that they give rise to...

Identification of a specific biomarker for cancer stem cells (CSCs) is of potential applications in the development of effective therapeutic strategies for renal cell carcinoma (RCC). In this study, both the RCC cell line 786-O and surgically removed clear cell RCC (ccRCC) tissues were implemented to grew as spheroids in serum-free medium supplemented with mitogens. This subpopulation possessed key characteristics defining CSCs. We also identified that surgically removed ccRCC tissues were heterogenic and there was a subpopulation of cells that was highly stained with rhodamine-123...

Transplantation of autologous mesenchymal stem cells (MSCs) has been shown to attenuate renal injury and dysfunction in several animal models, and its efficacy is currently being tested in clinical trials for patients with renal disease. Accumulating evidence indicates that MSCs release extracellular vesicles (EVs) that deliver genes, microRNAs and proteins to recipient cells, acting as mediators of MSC paracrine actions. In this context, it is critical to characterize the MSC-derived EV cargo to elucidate their potential contribution to renal repair...

Native extracellular matrix (ECM) provides scaffolds for tissue engineering with natural architecture and biochemical composition. Maintaining the native ECM in decellularized tissues provides cues for cells, which promote their tissue specific arrangement and function. Several approaches have been used to decellularize ECM from the kidney in order to reestablish renal tissue but their comparability is hampered because methods for decellularization and assessment of ECM vary widely. Therefore, we applied a standardized immersion protocol to decellularize porcine kidney tissue with three detergents Triton X-100, sodium dodecyl sulfate (SDS) and sodium deoxycholate (SDC) at variable temperatures...

Clofarabine is a purine nucleoside analog with immunosuppressive and anti-leukemic activity and its inclusion in reduced intensity regimens could potentially improve outcomes. We performed a prospective Phase I study of clofarabine combined with 2 Gy total body irradiation (TBI) as a non-myeloablative (NMA) preparative regimen for allogeneic stem cell transplantation in pediatric patients, who were considered at high risk of mortality from standard myeloablative regimens. The main goal of the study was to delineate the maximum feasible dose (MFD) of clofarabine in combination with 2 Gy TBI...

BACKGROUND: The administration of cisplatin is limited due to its nephrotoxic side effects, and prevention of this nephrotoxicity of cisplatin is difficult. Mesenchymal stem cell (MSC)-derived exosomes have been implicated as a novel therapeutic approach for tissue injury. In this study, we demonstrated that the pretreatment of human umbilical cord MSC-derived exosomes (hucMSC-Ex) can prevent the development of cisplatin-induced renal toxicity by activation of autophagy in vitro and in vivo...

Podocalyxin (PODXL) is a CD34-related sialomucin and a well-known marker of embryonic stem cells. PODXL is expressed in many types of tumors including colorectal cancers, breast cancers, and brain tumors. Overexpression of PODXL is an independent predictor of progression, metastasis, and poor outcome. PODXL is also expressed in many normal cells such as renal podocytes and endothelial cells (ECs). However, high-sensitive and high-specific anti-PODXL monoclonal antibodies (mAbs) have not been established. Herein, we immunized mice with recombinant human PODXL, which was produced using LN229 glioblastoma cells...

Light chain deposition disease (LCDD) is characterized by monotypic immunoglobulin depositions which will eventually lead to loss of organ function if left untreated. While the kidney is almost always affected, the presence and degree of LCDD in other organs vary. Ten to 30% of LCDD patients have underlying Multiple Myeloma (MM), yet outcome and prognostic markers in this particular patient group are still lacking. Here, we analyzed 69 patients with MM and biopsy proven LCDD and report on renal and extra-renal involvement and its impact on prognosis as well as renal response depending on hematologic response...

The relationships between exposure, biomarkers (vascular endothelial growth factor (VEGF), soluble VEGF receptors (sVEGFR)-1, 2, 3, and soluble stem cell factor receptor (sKIT)), tumor sum of longest diameters (SLD), diastolic blood pressure (dBP) and overall survival (OS) were investigated in a modeling framework. The dataset included 64 metastatic renal cell carcinoma patients (mRCC) treated with oral axitinib. Biomarker time-courses were described by indirect response (IDR) models where axitinib inhibits sVEGFR-1, 2 and 3 production, and VEGF degradation...

Previous studies have suggested that CD133(+) cells isolated from human kidney biopsies have the potential to ameliorate injury following intravenous (IV) administration in rodent models of kidney disease by integrating into damaged renal tissue and generating specialized renal cells. However, whether renal engraftment of CD133(+) cells is a prerequisite for ameliorating injury has not yet been unequivocally resolved. Here, we have established a cisplatin-induced nephropathy model in immunodeficient rats to assess the efficacy of CD133(+) human kidney cells in restoring renal health, and to determine the fate of these cells after systemic administration...

The DHAP regimen (high-dose cytarabine in combination with dexamethasone and cisplatin) with or without rituximab (DHAP+/-R) is one of the most common regimens in daily practice. It is considered the standard treatment for relapse or refractory Hodgkin's and non-Hodgkin's lymphoma (NHL). Cisplatin nephrotoxicity is a major concern, and other platinum compounds are being tried. We performed a monocentric retrospective analysis to evaluate the use of carboplatin, so-called DHAC+/-R regimen. The purpose was to assess the toxicity of the DHAC+/-R regimen in real-life...
