After contextualising the generic frameworks of nanotechnology and nanomedicine, the 2disciplines are discussed in the field of Nephrology. The potential downside to nanonephrology is the renal clearance of nanoparticles, the use of which is ever-increasing both for nanomedicinal purposes and in nanofoods. The positive impact of nanotechnology in Nephrology is centred on the development of renal nanodiagnostics for basic renal function studies, the early diagnosis of acute kidney injury, reliable and simple follow-up of chronic kidney disease and the improvement of magnetic resonance imaging...

Kidney organoid is an emerging topic of importance for research in kidney development and regeneration. Conventional culture systems for kidney organoids reported thus far use culture media containing serum, which may compromise our understanding and the potential clinical applicability of the organoid system. In our present study, we tested two serum-free culture conditions and compared their suitability for the maintenance and growth of kidney organoids in culture. One of the serum-free culture conditions was the combination of keratinocytes serum free medium (KSFM) with knockout serum replacement (KSR) (KSFM + KSR), and the other was the combination of knockout DMEM/F12 (KD/F12) and KSR (KD/F12 + KSR)...

Endothelial cells (EC) frequently undergo primary or secondary injury during kidney disease such as thrombotic microangiopathy or glomerulonephritis. Renin Lineage Cells (RLCs) serve as a progenitor cell niche after glomerular damage in the adult kidney. However, it is not clear whether RLCs also contribute to endothelial replenishment in the glomerulus following endothelial injury. Therefore, we investigated the role of RLCs as a potential progenitor niche for glomerular endothelial regeneration. We used an inducible tet-on triple-transgenic reporter strain mRen-rtTAm2/LC1/LacZ to pulse-label the renin-producing RLCs in adult mice...

Endothelial progenitor cells (EPC) are bone marrow derived or tissue-resident cells that play major roles in the maintenance of vascular integrity and repair of endothelial damage. Although EPCs may be capable of directly engrafting and regenerating the endothelium, the most important effects of EPCs seem to be depended on paracrine effects. In recent studies, specific microvesicles and mRNAs have been found to mediate the pro-angiogenic and regenerative effects of EPCs on endothelium. EPC counts have important prognostic implications in cardiovascular diseases (CVD)...

Early and adequate restoration of endothelial and tubular renal function is a substantial step during regeneration after ischemia reperfusion (IR) injury, occurring, e.g., in kidney transplantation, renal surgery, and sepsis. While tubular epithelial cell injury has long been of central importance, recent perception includes the renal vascular endothelium. In this regard, the fibrin cleavage product fibrinopeptide Bβ15-42 mitigate IR injury by stabilizing interendothelial junctions through its affinity to VE-cadherin...

Tissue engineering has been recognized as a translational approach to replace damaged tissue or whole organs. Engineering tissue, however, faces an outstanding knowledge gap in the challenge to fully recapitulate complex organ-specific features. Major components, such as cells, matrix, and architecture, must each be carefully controlled to engineer tissue-specific structure and function that mimics what is found in vivo. Here we review different methods to engineer tissue, and discuss critical challenges in recapitulating the unique features and functional units in four major organs-the kidney, liver, heart, and lung, which are also the top four candidates for organ transplantation in the USA...

Acute kidney injury frequently occurs in hospitalized patients all over the world. The prognosis remains poor since specific therapies for promoting kidney regeneration/repair are still missing. In recent years cell-based strategies have improved AKI outcomes under experimental circumstances. Four groups of cells, each of them displaying certain biological and functional characteristics have been evaluated in AKI, induced Pluripotent Stem Cells (iPSCs), Spermatagonial Stem Cells (SSCs), Proangiogenic Cells (PACs) and Endothelial Colony Forming Cells (ECFCs), and Mesenchymal Stem Cells (MSCs)...

Endothelial progenitor cells are circulating blood cells derived from various sources like bone marrow, spleen, umbilical cord, liver, kidney and other sources that play a vital role in the regeneration of endothelial lining of blood vessels and wound repair. There are two types of EPCs, early EPCs and late EPCs. EPCs are believed to originate from hematopoietic stem cells and mesenchymal stem cells. The mobilization of progenitor cells from bone marrow to the peripheral circulation is highly regulated under both normal physiological conditions and stress...

BACKGROUND: Although adult human tissue-derived epidermal stem cells are capable of differentiating into enamel-secreting ameloblasts and forming teeth with regenerated enamel when recombined with mouse dental mesenchyme that possesses odontogenic potential, the induction rate is relatively low. In addition, whether the regenerated enamel retains a running pattern of prism identical to and acquires mechanical properties comparable with human enamel indeed warrants further study. METHODS: Cultured human keratinocyte stem cells (hKSCs) were treated with fibroblast growth factor 8 (FGF8) and Sonic hedgehog (SHH) for 18 h or 36 h prior to being recombined with E13...

Failure of solid organs, such as heart, liver and kidney, remains a major cause of the world's mortality due to critical shortage of donor organs. Tissue engineering, which uses elements including cells, scaffolds and growth factors to fabricate functional organs in vitro, is a promising strategy to mitigate the scarcity of transplantable organs. Within recent years, different construction strategies which guide the combination of tissue engineering elements have been applied in solid organ tissue engineering and have achieved much progress...

Cylindrospermopsin (CYN) is a toxin associated with numerous species of freshwater cyanobacteria throughout the world. It is postulated to have caused an episode of serious illnesses in Australia through treated drinking water, as well as lethal effects in livestock exposed to water from farm ponds. Toxicity included effects indicative of both hepatic and renal dysfunction. In humans, symptoms progressed from initial hepatomegaly, vomiting, and malaise to acidosis and hypokalemia, bloody diarrhea, and hyperemia in mucous membranes...

BACKGROUND: Cold storage is poorly tolerated by kidney grafts retrieved after Donation after Circulatory Death (DCD). It has been determined that normothermic ex vivo kidney perfusion (NEVKP) preservation decreases injury by minimizing cold ischemic storage. The impact of NEVKP on warm ischemic injury is unknown. METHODS: We compared pig kidneys retrieved after 30minutes warm ischemia and immediate transplantation (no-preservation) with grafts that were exposed to 30min of warm ischemia plus 8hr NEVKP or plus 8hr SCS...

Severe traumatic brain injury (STBI) is characterized by a primary injury which cannot be reversed and a secondary injury that can be prevented or reversed. Management of STBI patients in intensive care mainly aims at preventing the secondary injury. Treatment aims to: reducing ICP pressure (that can result in an ischemic insult); avoiding hypotension, hyperthermia, or hypoxemia; maintaining a normal electrolytes homeostasis; treating the Autonomic dysfunction syndrome, coagulopathies, Acute Kidney Injury and maintaining an adequate nutrition...

BACKGROUND/AIMS: Physical training has beneficial effects on endothelial function and can influence the regeneration of the endothelial cell. We investigated the effect of physical training on cisplatin (CP)-induced acute kidney injury and assessed the impact of training on endothelial structure and function, and on the inflammatory processes in rats. METHODS: We injected male Wistar rats subjected to previous physical training in treadmill running (trained, TR) or not (sedentary, SED) with CP (5 mg/kg) (TR+CP and SED+CP groups, respectively)...

Progression of chronic kidney disease associated with progressive fibrosis and impaired tubular epithelial regeneration is still an unmet biomedical challenge, because once chronic lesions have manifested, no effective therapies are available as of yet for clinical use. Prompted by various studies across multiple organs demonstrating that preconditioning regimens to induce endogenous regenerative mechanisms protect various organs from later incurring acute injuries, we here aimed to gain insights into the molecular mechanisms underlying successful protection and to explore whether such pathways could be utilized to inhibit progression of chronic organ injury...

As a traditional concept of Chinese medicine (CM), the theory of "Shen (Kidney) controlling bones" has been gradually proven. And in modern allopathic medicine, the multiple mechanisms of bone growth, development and regeneration align with the theory. Shen defifi ciency as a pathological condition has a negative effect on the skeleton of body, specififi cally the disorder of bone homeostasis. Present studies indicate that Shen defifi ciency shares a common disorder characterized by dysfunction of hypothalamic-pituitary-adrenal (HPA) axis...

Mesenchymal stem cells (MSCs) are a source for cell-based therapy. Although MSCs have the potential for tissue regeneration, their therapeutic efficacy is restricted by the uremic toxin, p -cresol, in chronic kidney disease (CKD). To address this issue, we investigated the effect of fucoidan, a marine sulfated polysaccharide, on cellular senescence in MSCs. After p -cresol exposure, MSC senescence was induced, as indicated by an increase in cell size and a decrease in proliferation capacity. Treatment of senescent MSCs with fucoidan significantly reversed this cellular senescence via regulation of SMP30 and p21, and increased proliferation through the regulation of cell cycle-associated proteins (CDK2, CDK4, cyclin D1, and cyclin E)...

The decellularized (DC) scaffolds retain three-dimensional structures for the stimulation of cell growth, with components of the extracellular matrix (ECM) relatively conserved between species. The strategy based on decellularized scaffolds provides a new way for organ regeneration, with a number of prominent advances having been reported in the past few years. While their lack of biomechanical strength and excessive degradation limit the clinical applications, therefore it is urgent to modify the DC scaffolds to improve the performance...

Nephron induction during kidney development is driven by reciprocal interactions between progenitor cells (NPCs) of the cap mesenchyme (CM) and the ureteric bud (UB). The prorenin receptor (PRR) is a receptor for renin and prorenin, and an accessory subunit of the vacuolar proton pump V-ATPase. Previously, we demonstrated that conditional ablation of the PRR in Six2+ NPCs in mice (Six2PRR -/- ) causes early neonatal death. Here, we identified genes that are regulated by PRR in Six2+ NPCs FACS-isolated from Six2PRR -/- and control kidneys on embryonic day E15...
