Effect of Human Amniotic Fluid Stem Cells on Kidney Function in a Model of Chronic Kidney Disease.

ABSTRACT: Kidney disease is a major medical problem globally. Chronic kidney disease (CKD) is a progressive loss of kidney function. It causes accumulation of waste and fluid in the body, eventually resulting in kidney failure as well as damaging other organs. Although dialysis and kidney transplantation have been used as primary treatments for renal disease, dialysis does not restore full renal function, and there is a shortage of donor kidneys for transplantation. Recent advances in cell-based therapies have offered a means to augment and restore renal function. Various types of cells have been tested to evaluate their therapeutic effects on injured kidneys. Among various types of cells, amniotic fluid stem cells (AFSCs) share advantages of both embryonic and adult stem cells, such as pluripotent activity, remarkable plasticity, and immunomodulatory effects, which may allow their future therapeutic use as an "off-the-shelf" cell source. AFSC presents advantages of both conventional pluripotent and adult stem cells, such as pluripotent activity, remarkable plasticity, and immunomodulatory effects. This study demonstrates that administration of human-derived AFSC facilitates functional and structural improvement in a rat model of CKD, and suggests that cell therapy with AFSC has potential as a therapeutic strategy to recover renal function in patients with CKD. Impact Statement Patients with chronic kidney disease (CKD) have limited treatment options, and renal transplantation is the only definitive treatment method that restores kidney function. However, challenges associated with transplantation, including donor organ shortage, rejection, and life-long immunosuppression, remain a problem. Recently, stem cell-based therapies have been proposed as an alternative approach to augment and restore renal function. In this study, we used human-derived amniotic fluid stem cells (AFSCs) to treat CKD in a rat model and demonstrated that AFSC treatment facilitated positive effects in terms of improvements of renal function.

Project description:BackgroundDiabetes mellitus (DM) is a serious and growing global health burden. It is estimated that 80% of diabetic patients have micturition problems such as poor emptying, urinary incontinence, urgency, and urgency incontinence. Patients with diabetic bladder dysfunction are often resistant to currently available therapies. It is necessary to develop new and effective treatment methods.AimTo examine the therapeutic effect of human amniotic fluid stem cells (hAFSCs) therapy on bladder dysfunction in a type 2 diabetic rat model.MethodsSixty female Sprague-Dawley rats were divided into five groups: Group 1, normal-diet control (control); group 2, high-fat diet (HFD); group 3, HFD plus streptozotocin-induced DM (DM); group 4, DM plus insulin treatment (DM + insulin); group 5, DM plus hAFSCs injection via tail vein (DM + hAFSCs). Conscious cystometric studies were done at 4 and 12 wk after insulin or hAFSCs treatment to measure peak voiding pressure, voided volume, intercontraction interval, bladder capacity, and residual volume. Immunoreactivities and/or mRNA expression of muscarinic receptors, nerve growth factor (NGF), and sensory nerve markers in the bladder and insulin, MafA, and pancreatic-duodenal homeobox-1 (PDX-1) in pancreatic beta cells were studied.ResultsCompared with DM rats, insulin but not hAFSCs treatment could reduce the bladder weight and improve the voided volume, intercontraction interval, bladder capacity, and residual volume (P < 0.05). However, both insulin and hAFSCs treatment could help to regain the blood glucose and bladder functions to the levels near controls (P > 0.05). The immunoreactivities and mRNA expression of M2- and M3-muscarinic receptors (M2 and M3) were increased mainly at 4 wk (P < 0.05), while the number of beta cells in islets and the immunoreactivities and/or mRNA of NGF, calcitonin gene-related peptide (CGRP), substance P, insulin, MafA, and PDX-1 were decreased in DM rats (P < 0.05). However, insulin and hAFSCs treatment could help to regain the expression of M2, M3, NGF, CGRP, substance P, MafA, and PDX-1 to near the levels of controls at 4 and/or 12 wk (P > 0.05).ConclusionInsulin but not hAFSCs therapy can recover the bladder dysfunction caused by DM; however, hAFSCs and insulin therapy can help to regain bladder function to near the levels of control.
