The inhibitor of growth family, member 3 (ING3) protein may be capable of blocking the cell cycle via activating p53-transactivated promoters of p21 and Bcl2-associated X protein, and may induce apoptosis via a Fas/caspase-8-dependent signaling pathway. In the present study, immunohistochemistry was performed in order to characterize the expression profile of ING3 protein in tissue microarrays containing mouse and human normal tissue, human hepatocellular (n=62), renal clear cell (n=62), pancreatic (n=62), esophageal squamous cell (n=45), cervical squamous cell (n=31), breast (n=144), gastric (n=196), colorectal (n=96), ovarian (n=208), endometrial (n=96) and lung carcinoma (n=192)...

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...

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...

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...

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...

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...

Renovascular hypertension (RVH) is a progressive disease, leading to chronic kidney disease when untreated and no specific treatment is available. Therefore, development of new therapeutic modalities is imperative. RVH is triggered by renal artery stenosis and subsequent renin-angiotensin-aldosterone system activation; it can be experimentally induced by the 2 Kidneys-1 Clip (2K1C) model. This study investigates the therapeutic potential of renal subcapsular mesenchymal stem cell (MSC) infusion in 2K1C rats...

Induction of allograft tolerance has been considered the ultimate goal in organ transplantation. Although numerous protocols to induce allograft tolerance have been reported in mice, a chimerism-based approach through donor haematopoietic stem cell transplantation has been the only approach to date that induced allograft tolerance reproducibly following kidney transplantation in man. Renal allograft tolerance has been achieved by induction of either transient mixed chimerism or persistent full donor chimerism...

An organoid can be defined as a three-dimensional organ-like structure formed from organ-specific progenitor cells. Organ progenitor cells were empirically found to self-organize three-dimensional tissues when they were aggregated and cultivated in vitro. While this nature power of progenitor cells has an amazing potential to recreate artificial organs in vitro, there had been difficulty to apply this technology to human organs due to the inaccessibility to human progenitor cells until human-induced pluripotent stem cell (hiPSC) was invented by Takahashi and Yamanaka in 2007...

Preemptive treatment with mesenchymal stem cells (MSCs) can attenuate cisplatin-induced acute kidney injury (AKI). However, it is uncertain whether MSC treatment after the development of renal dysfunction prevents AKI progression, or if their immunomodulatory properties contribute to MSC therapy. In this study, human umbilical cord blood (hUCB)-derived MSCs were used to compare the effects and mechanisms of early and late MSC therapy in a murine model. After cisplatin injection into C57BL/6 mice, hUCB-MSCs were administered on day 1 (early treatment) or day 3 (late treatment)...

4-Pirydone-3-carboxamide-1β-D-ribonucleoside (4PYR) is an endogenous nucleoside that could be converted to triphosphates, diphosphates, monophosphates and an analogue of NAD - 4PYRAD. Elevated level of these compounds were observed in chronic renal failure, cancer and active HIV infection. However, little is known about the effect on cell functionality and the metabolic pathways. This study tested effects of 4PYR in different cell types on nucleotide and energy metabolism and clarified enzymes that are involved in conversions of 4PYR...

Kidney diseases are a public health problem worldwide; the mortality rate is between 50 and 80%. Available therapies include replacement function by dialysis or transplant, associated with a high morbidity and mortality; kidney transplantation is limited by the shortage of donor organs, immune rejection and lifelong treatment with immunosuppressive. Likewise, none of these treatments compensates all kidney functions. There is a great concern in developing more effective therapies with the ability to replace the wide range of renal functions, so that, new researches on developing therapeutic strategies have focused on regenerative medicine, science that includes artificial creation of tissues and organs, in order to repair or replace a tissue or organ function...

Acute kidney injury (AKI) is characterized by an increasing incidence and poor outcomes in both developed and undeveloped countries. AKI is also acquiring importance in the setting of kidney transplantation (KT): besides all the classical forms of AKI that KT patients may undergo, several transplant-specific injuries can also lead to the loss of graft function. The mechanisms of tissue damage in native and grafted kidneys share several common pathogenic elements. Since appropriate therapeutic treatments are still lacking-probably due to the disease complexity-clinicians are forced to provide only supportive care...

Renal cell carcinoma (RCC) is the most lethal of the common urologic malignancies, comprising 3% of all human neoplasms, and the incidence of kidney cancer is rising annually. We need new approaches to target tumor cells that are resistant to current therapies and that give rise to recurrence and treatment failure. In this study, we focused on low oxygen tension and three-dimensional (3D) cell culture incorporation to develop a new RCC growth model. We used the hanging drop and colony formation methods, which are common in 3D culture, as well as a unique methylcellulose (MC) method...

Accumulation of myofibroblasts is a hallmark of renal fibrosis. A significant proportion of myofibroblasts has been reported to originate via endothelial-mesenchymal transition. We initially hypothesized that exposing myofibroblasts to the extract of endothelial progenitor cells (EPCs) could reverse this transition. Indeed, in vitro treatment of transforming growth factor-β1 (TGF-β1)-activated fibroblasts with EPC extract prevented expression of α-smooth muscle actin (α-SMA); however, it did not enhance expression of endothelial markers...

Stem cells therapy has been suggested as a promising option for the treatment of acute kidney injury (AKI). This study was performed to compare the abilities of xenogenic transplantation of human adipose stromal vascular fraction (SVF) and adipose-derived mesenchymal stem cells (AdMSCs) to facilitate the recovery of renal function and structure in a rat model of ischemia/reperfusion (IR) induced AKI. SVF or AdMSCs were transplanted to the injured kidney through intra-parenchymal injection. Significantly improved renal function and reduced tubular injury were observed in SVF and AdMSCs groups...
