Mesodermal populations can be generated in vitro from mouse embryonic stem cells (mESCs) using three-dimensional (3-D) aggregates called embryoid bodies or two-dimensional (2-D) monolayer culture systems. Here, we investigated whether Brachyury -expressing mesodermal cells generated using 3-D or 2-D culture systems are equivalent, or instead, have different properties. Using a Brachyury -GFP/E2-Crimson reporter mESC line, we isolated Brachyury- GFP+ mesoderm cells using flow-activated cell sorting and compared their gene expression profiles and ex vivo differentiation patterns...

Proper control of multipotent/stem cell number and fate is essential for ensuing organ formation during development. β1-integrin, a subfamily of cell surface receptors, has a conserved role in maintenance of multipotent/stem cells, including renal progenitor cells, follicle stem cells, epidermal stem cells and neural stem cells. However, it remains unclear whether β1-integrin has a role in cardiac progenitor cell (CPC) development. Here we show that a mesodermal deletion of β1-integrin decreases Isl1+ cell number in the second pharyngeal arch (PA2), where CPCs undergo renewal and expansion...

BACKGROUND: Fanconi anaemia (FA) is an inherited disease with bone marrow failure, variable congenital and developmental abnormalities, and cancer predisposition. With improved survival, non-haematological manifestations of FA become increasingly important for long-term management. While renal abnormalities are recognized, detailed data on patterns and frequency and implications for long-term management are sparse. METHODS: We reviewed clinical course and imaging findings of FA patients with respect to renal complications in our centre over a 25-year period to formulate some practical suggestions for guidelines for management of renal problems associated with FA...

Amniotic fluid is an alternative source of stem cells, and human amniotic fluid-derived stem cells (AFSCs) obtained from a small amount of amniotic fluid collected during the second trimester represent a novel source for use in regenerative medicine. These AFSCs are characterized by lower diversity, a higher proliferation rate and a wider differentiation capability than adult mesenchymal stem cells (MSCs). AFSCs are selected based on the cell surface marker c-kit receptor (CD117) using immunomagnetic sorting...

Microsporidiosis is a rare, but emerging opportunistic infection in solid organ transplant and stem cell transplant recipients. Renal involvement in microsporidiosis is very rarely seen in these recipients. We describe two cases of pediatric renal microsporidiosis, diagnosed on renal biopsies, following bone marrow transplantation presenting as severe acute kidney injury. The first patient died, whereas the second survived due to early diagnosis based on high index of suspicion and prompt treatment with Albendazole...

Autologous stem cell transplantation (ASCT) is considered as standard of care in patients with multiple myeloma (MM) patients aged 65 years or younger. We analyzed data of 94 patients of plasma cell dyscrasias who underwent 95 autologous transplants at our institute from October 2003 to Aug 2016. Other than 76 patients of newly diagnosed multiple myeloma, we also transplanted two patients of POEMS syndrome, two patients of plasma cell leukemia, three patients of concurrent light chain deposition disease, three patients of multifocal plasmacytomas, and eight patients of isolated light chain myeloma...

Mesenchymal stem cell‑conditioned medium (MSC‑CM) contains various cytokines (osteopontin and macrophage colony stimulating factor 1) secreted by MSCs and may modulate the immune response in tubulointerstitial fibrosis. The aim of the present study was to investigate whether MSC‑CM treatment may affect B cell‑dependent immune responses, which have previously been reported to facilitate the renal fibrotic processes following unilateral ureteral obstruction (UUO). In the present study, histological analysis, flow cytometry, western blotting and reverse transcription‑quantitative polymerase chain reaction were performed...

Fabry's disease is a genetic disorder of X-linked inheritance caused by mutations in the alpha galactosidase A gene resulting in deficiency of this lysosomal enzyme. The progressive accumulation of glycosphingolipids, caused by the inadequate enzymatic activity, is responsible of organ dysfunction and thus of clinical manifestations. In presence of a high clinical suspicion, a careful physical examination and specific laboratory tests are required, finally diagnosis of Fabry's disease is confirmed by demonstration of absence or reduced alpha galactosidase A enzyme activity in hemizygous men and gene typing in heterozygous females; in fact the performance of enzymatic activity assay alone in women is inconclusive...

We evaluated the impact of light chain type, lambda (λ) or kappa (κ), on disease features and outcomes in patients with immunoglobulin light chain (AL) amyloidosis receiving stem cell transplant at the Mayo Clinic between October 2002 and August 2016. Patients with λ AL amyloidosis had higher rates of renal and neurological involvement (λ 69% vs κ 57%, P = .02 and λ 16% vs κ 9%, P = .03, respectively). Patients with κ AL amyloidosis had more hepatic involvement (λ 7% vs κ 18%, P = .0003). Complete response rate was 43% for both groups and overall response rates were similar (λ 85% vs κ 91%, P = ...

In the XXI century diabetes mellitus has become one of the main threats to human health with higher incidence in regions such as Europe and North America. Type 1 diabetes mellitus (T1DM) occurs as a consequence of the immune-mediated destruction of insulin producing β-cells located in the endocrine part of the pancreas, the islets of Langerhans. The administration of exogenous insulin through daily injections is the most prominent treatment for T1DM but its administration is frequently associated to failure in glucose metabolism control, finally leading to hyperglycemia episodes...

BACKGROUND: Acute kidney injury (AKI) leads to serious renal damage, and early inhibition of inflammation is necessary for its treatment. C5a/C5aR signaling activation promotes inflammatory response in tissue injury. Anti-inflammatory activity of mesenchymal stem cells (MSCs) makes it possible to alleviate AKI by controlling the C5a/C5aR signaling activation. METHODS: Ischemia reperfusion (I/R)-induced AKI models in wild-type and C5aR KO mice were used. In addition, human bone marrow MSCs (hBM-MSCs) or C5aR antagonist were injected in this model...

Cystinosis is a rare autosomal recessive lysosomal storage disorder caused by mutations in the CTNS gene. Main dysfunction is a defective clearance of cystine from lysosomes that leads to accumulation of cystine crystals in every tissue of the body. There are three different forms: infantile nephropathic cystinosis, which is the most common form, juvenile nephropatic, and non-nephropathic cystinosis. Mostly, first symptom in infantile nephropathic cystinosis is renal Fanconi syndrome that occurs within the first year of life...

Advancements in hematopoietic cell transplantation (HCT) have broadened indications for its use and resulted in more long-term survivors. Stem cell transplantation is associated with several well-known toxicities, although renal complications are not well defined. Acute and chronic kidney disease remains a common complication following transplantation itself. Incidence and risk factors for the development of chronic kidney disease (CKD) is less well understood. Recent estimates suggest that nearly 15% of subjects undergoing HCT will develop CKD, a complication that can progress to end-stage renal disease (ESRD), disrupts overall quality of life, and reduces overall survival...

Renal cell carcinoma (RCC) is a common and devastating disease characterized by a hypoxic microenvironment, epithelial-mesenchymal transition, and potent resistance to therapy evidencing the presence of cancer stem cells (CSCs). Various CSC markers have been studied in RCC, but overall there is limited data on their role and most markers studied have been relatively non-specific. Doublecortin-like kinase 1 (DCLK1) is a validated CSC marker in the gastrointestinal tract and evidence for an equivalent role in other cancers is accumulating...

Kidney-derived c-Kit+ cells exhibit progenitor/stem cell properties in vitro (self-renewal capacity, clonogenicity, and multipotentiality). These cells can regenerate epithelial tubular cells following ischemia-reperfusion injury and accelerate foot processes effacement reversal in a model of acute proteinuria in rats. Several mechanisms are involved in kidney regeneration by kidney-derived c-Kit+ cells, including cell engraftment and differentiation into renal-like structures, such as tubules, vessels, and podocytes...

Interferon (IFN) gamma is the prototypic proinflammatory cytokine used to preactivate the immunomodulatory properties of mesenchymal stem cells (MSC). IFN-gamma, however, converts MSC into a cell therapy that can be immunogenic, detrimental, and hence nonfeasible for clinical application. The article by Bai et al. is an in vivo proof-of-concept study that interleukin-17A (IL-17A) enhances the immunosuppressive, tolerance-promoting, and renoprotective properties of MSC. IL-17A is an alternative cytokine to preactivate MSC...

Renal interstitial fibrosis is a final pathway that is observed in various types of kidney diseases, including diabetic kidney disease (DKD). The present study investigated the effect of tranilast on renal interstitial fibrosis and the association between its role and mast cell infiltration in a rat model of DKD. A total of 30 healthy 6‑week‑old male Sprague‑Dawley rats were randomly divided into the following four groups: Normal control group; DKD model group; low‑dose tranilast group (200 mg/kg/day); and high‑dose tranilast group (400 mg/kg/day)...
