Curr Stem Cell Res Ther 2024; 19:103-115. [PMID: 36999714 DOI: 10.2174/1574888x18666230331123540] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 12/30/2022] [Accepted: 01/26/2023] [Indexed: 04/01/2023]
Abstract
BACKGROUND Urine-derived stem cells (USCs) were considered to be an ideal source of stem cells for repairing urological diseases. However, the proliferative ability of USCs significantly decreased when cultured on plastic dishes, which limited their clinical application. It was found that collagen gels could promote the proliferation of USCs, but the underlying molecular mechanisms were unclear. OBJECTIVE The study aims to investigate the role of the mechanically activated cation channel Piezo1 and the transcriptional coactivator YAP in the regulation of proliferation of USCs on collagen gels. METHODS USCs were cultured on collagen gels (group COL), or plastic dishes (group NON). MTT assay, Scratch assay, EDU staining, and immunofluorescence (IF) of Ki67 were performed to evaluate the proliferation of USCs; IF of YAP was conducted to observe its nuclear localization; calcium imaging experiment was executed to evaluate the function of Piezo1; western blot was used to compare changes in protein expression of YAP, LATS1, ERK1/2, and p-ERK1/2. In addition, the regulatory effect of YAP on the proliferative capacity of USCs was confirmed by intervening YAP with its inhibitor verteporfin (VP); and the inhibitor or activator of Piezo1, GsMTx4 or Yoda1 was used to explore the effect of Piezo1 on the nuclear localization of YAP, the proliferation of USCs and the regeneration of injured bladder. RESULTS The results showed that cell proliferation was significantly enhanced in USCs in the COL group with the nuclear accumulation of YAP compared with the NON group and VP attenuated these effects. The expression and function of Piezo1 were higher in the COL group compared with the NON group. Blockage of Piezo1 by GsMTx4 decreased nuclear localization of YAP, the proliferation of USCs, and caused the failure of bladder reconstruction. Activation of Piezo1 by Yoda1 increased the nuclear expression of YAP, and the proliferation of USCs, which further improved the regeneration of the injured bladder. Finally, the ERK1/2 rather than LATS1 was revealed to participate in the Piezo1/YAP signal cascades of USCs proliferation. CONCLUSION Taken together, Piezo1-ERK1/2-YAP signal cascades were involved in regulating the proliferation ability of USCs in collagen gels which would be beneficial for the regeneration of the bladder.

Abstract
Exosomes, small tiny vesicle contains a large number of intracellular particles that employ to cause various diseases and prevent several pathological events as well in the human body. It is considered a "double-edged sword", and depending on its biological source, the action of exosomes varies under physiological conditions. Also, the isolation and characterization of the exosomes should be performed accurately and the methodology also will vary depending on the exosome source. Moreover, the uptake of exosomes from the recipients' cells is a vital and initial step for all the physiological actions. There are different mechanisms present in the exosomes' cellular uptake to deliver their cargo to acceptor cells. Once the exosomal uptake takes place, it releases the intracellular particles that leads to activate the physiological response. Even though exosomes have lavish functions, there are some challenges associated with every step of their preparation to bring potential therapeutic efficacy. So, overcoming the pitfalls would give a desired quantity of exosomes with high purity.

Abstract
Peritoneal fibrosis (PF) is a pathophysiological condition caused by a variety of pathogenic factors. The most important features of PF are mesothelial-mesenchymal transition and accumulation of activated (myo-)fibroblasts, which hinder effective treatment; thus, it is critical to identify other practical approaches. Recently, stem cell (SC) therapy has been indicated to be a potential strategy for this disease. Increasing evidence suggests that many kinds of SCs alleviate PF mainly by differentiating into mesothelial cells; secreting cytokines and extracellular vesicles; or modulating immune cells, particularly macrophages. However, there are relatively few articles summarizing research in this direction. In this review, we summarize the risk factors for PF and discuss the therapeutic roles of SCs from different sources. In addition, we outline effective approaches and potential mechanisms of SC therapy for PF. We hope that our review of articles in this area will provide further inspiration for research on the use of SCs in PF treatment.

Abstract
Critical roles of stem cell-extracellular vesicles (EVs) in the management of osteoporosis have been documented. Here, this study was designed to enlarge the research of the specific effects and underlying mechanism of urine-derived stem cells-EVs (USCs-EVs) on osteoporosis in diabetes rats. Firstly, miR-26a-5p and histone deacetylase 4 (HDAC4) expression in USCs of rats after diabetic osteoporosis (DOP) modeling induced by streptozotocin injection was determined, followed by study of their interaction. Then, USCs-EVs were co-cultured with osteogenic precursor cells, the effects of miRNA-26a-5p (miR-26a-5p) on osteoblasts, osteoclasts, bone mineralization deposition rate were evaluated. Meanwhile, the effect of USCs-EVs carrying miR-26a-5p on DOP rats was assessed. Elevated miR-26a-5p was seen in USCs-EVs which limited HDAC4 expression. Moreover, USCs-EVs delivered miR-26a-5p to osteogenic precursor cells, thereby promoting their differentiation, enhancing the activity of osteoblasts, and inhibiting the activity of osteoclasts, thereby preventing DOP through the activation of hypoxia inducible factor 1 subunit alpha (HIF-1α)/vascular endothelial growth factor A (VEGFA) pathway by repressing HDAC4. In a word, USCs-EVs-miR-26a-5p is a promising therapy for DOP by activating HIF-1α/VEGFA pathway through HDAC4 inhibition. 1. USCs-EVs-miR-26a-5p targeted HDAC4 and limited HDAC4 expression. 2. miR-26a-5p was delivered by USCs-EVs into osteoblast precursor cells. 3. USCs-EVs-miR-26a-5p promoted the differentiation of osteoblast precursor cells into osteoblasts. 4. miR-26a-5p delivered by USCs-EVs could inhibit HDAC4. 5. USCs-EVs-miR-26a-5p could prevent the pathogenesis of DOP via HIF-1α/VEGFA aix.

Abstract
DNA sequencing is a reliable tool for identifying genetic variants in osteogenesis imperfecta (OI) but cannot always establish pathogenicity, particularly in variants altering splicing. RNA sequencing can provide functional evidence of the effect of a variant on the transcript but requires cells expressing the relevant genes. Here, we used urine-derived cells (UDC) to characterize genetic variants in patients with suspected or confirmed OI and provide evidence on the pathogenicity of variants of uncertain significance (VUS). Urine samples were obtained from 45 children and adolescents; UDC culture was successful in 40 of these participants (age range 4-20 years, 21 females), including 18 participants with OI or suspected OI who had a candidate variant or VUS on DNA sequencing. RNA was extracted from UDC and sequenced on an Illumina NextSeq550 device. Principal component analysis showed that the gene expression profiles of UDC and fibroblasts (based on Genotype Tissue Expression [GTEx] Consortium data) clustered close together and had less variability than those of whole blood cells. Transcript abundance was sufficient for analysis by RNA sequencing (defined as a median gene expression level of ≥10 transcripts per million) for 25 of the 32 bone fragility genes (78%) that were included in our diagnostic DNA sequencing panel. These results were similar to GTEx data for fibroblasts. Abnormal splicing was identified in 7 of the 8 participants with pathogenic or likely pathogenic variants in the splice region or deeper within the intron. Abnormal splicing was also observed in 2 VUS (COL1A1 c.2829+5G>A and COL1A2 c.693+6T>G), but no splice abnormality was observed in 3 other VUS. Abnormal deletions and duplications could also be observed in UDC transcripts. In conclusion, UDC are suitable for RNA transcript analysis in patients with suspected OI and can provide functional evidence for pathogenicity, in particular of variants affecting splicing. © 2023 The Authors.

Abstract
Bone regeneration after injury or after surgical bone removal due to disease is a serious medical challenge. A variety of materials are being tested to replace a missing bone or tooth. Regeneration requires cells capable of proliferation and differentiation in bone tissue. Although there are many possible human cell types available for use as a model for each phase of this process, no cell type is ideal for each phase. Osteosarcoma cells are preferred for initial adhesion assays due to their easy cultivation and fast proliferation, but they are not suitable for subsequent differentiation testing due to their cancer origin and genetic differences from normal bone tissue. Mesenchymal stem cells are more suitable for biocompatibility testing, because they mimic natural conditions in healthy bone, but they proliferate more slowly, soon undergo senescence, and some subpopulations may exhibit weak osteodifferentiation. Primary human osteoblasts provide relevant results in evaluating the effect of biomaterials on cellular activity; however, their resources are limited for the same reasons, like for mesenchymal stem cells. This review article provides an overview of cell models for biocompatibility testing of materials used in bone tissue research.

Abstract
Ciliopathies comprise a group of inherited diseases caused by mutations in genes encoding proteins that localize to cilia or centrosomes. They afflict multiple organs and are one of the most frequent monogenic causes of kidney failure in adults, adolescents and children. Primary cilia play diverse roles in cell signaling, cell cycle regulation, planar cell polarity and mechanosensing. The use of patient-derived cells possessing endogenous disease causing mutations enables the study of these processes and their dysregulation in disease. Here we describe methods to cultivate patient-derived dermal fibroblast and renal epithelial cells isolated from urine. Fibroblasts are highly robust, long-lived, and easy to culture cells in which ciliary assembly can be easily induced. Similarly, the ability to acquire and culture ciliated renal epithelial cells without patient-invasive-intervention holds great potential to further our understanding of ciliopathies. In addition to monolayer cultures, we also detail the formation of three-dimensional renal-epithelial organoids-so-called tubuloids-that demonstrate epithelial-polarization and transepithelial transport activities like those seen in vivo renal-tubules. These in vitro models are powerful tools to investigate the underlying disease mechanisms of human ciliopathies that can be employed without the need for heavy-handed genetic or molecular manipulations.

Abstract
Mesenchymal/medicinal stem/signaling cells (MSCs), well known for regenerative potential, have been involved in hundreds of clinical trials. Even if equipped with reparative properties, aging significantly decreases their biological activity, representing a major challenge for MSC-based therapies. Age-related joint diseases, such as osteoarthritis, are associated with the accumulation of senescent cells, including synovial MSCs. An impaired ability of MSCs to self-renew and differentiate is one of the main contributors to the human aging process. Moreover, senescent MSCs (sMSCs) are characterized by the senescence-messaging secretome (SMS), which is typically manifested by the release of molecules with an adverse effect. Many factors, from genetic and metabolic pathways to environmental stressors, participate in the regulation of the senescent phenotype of MSCs. To better understand cellular senescence in MSCs, this review discusses the characteristics of sMSCs, their role in cartilage and synovial joint aging, and current rejuvenation approaches to delay/reverse age-related pathological changes, providing evidence from in vivo experiments as well.

Abstract
Background Due to the large area and deep width of the artificial neovagina after vaginoplasty, it takes a considerable amount of time to achieve complete epithelization of the neovagina. Currently, the clinical therapies for vaginal epithelization after vaginoplasty are still dissatisfactory. Recent studies showed that small extracellular vesicles (sEVs) derived from stem cells could accelerate wound epithelization. The sustained release of sEVs from optimized hydrogels may be a promising strategy to accelerate vaginal epithelization after vaginoplasty. Methods The efficacy of phototriggered imine crosslink hydrogels (piGEL) containing sEVs derived from human urine-derived stem cells (hUSC-sEVs, piGEL-sEVs) on vaginal mucosa defects in rabbits was assessed by wound closure rates, histological analysis and immunofluorescence staining analysis. Cell counting kit-8, 5-ethynyl-2′-deoxyuridine and scratch wound assays were performed to assess the effects of hUSC-sEVs on the proliferation and migration ability of vaginal epithelial cells (VK2/E6E7). Quantitative real-time polymerase chain reaction (qRT-PCR) was carried out to test the expression of epithelial differentiation markers in VK2 cells. Moreover, a microRNA (miRNA) microarray was used to find hUSC-sEVs-specific miRNAs that potentially affected the proliferation, migration and differentiation ability of VK2 cells. Results The in vitro release profile revealed that the piGEL could ensure sustained release of hUSC-sEVs. The in vivo results showed that piGEL-sEVs effectively promoted epithelization and angiogenesis of vaginal mucosa defects in rabbits. According to miRNA microarray and qRT-PCR results, miR-126-3p might be the crucial molecule among the various miRNAs contained in hUSC-sEVs. The data showed that hUSC-sEVs promoted the migration and differentiation of VK2 cells by delivering miR-126-3p to suppress the expression of Spred1 and PIK3R2, thereby activating the ERK1/2 and ATK signaling pathways. Conclusion The results indicated that piGEL-sEVs could be a novel promising approach for enhancing the epithelization of the neovagina after vaginoplasty and provided useful data for understanding the underlying mechanism of the effect of hUSC-sEVs on epithelization.

Abstract
Bone defects still pose various challenges in osteology. As one treatment method for bone defects, tissue engineering requires biomaterials with good biocompatibility and stem cells with good differentiation. This study aimed to fabricate a 3D-printed polylactic acid and hydroxyapatite (PLA/HA) composite scaffold with urine-derived stem cells (USCs) to study its therapeutic effect in a rat model of skull defects. USCs were isolated and extracted from the urine of healthy adult males and inoculated onto PLA/HA and PLA scaffolds fabricated by 3D printing technology. A total of 36 skull defect models in eighteen Sprague-Dawley rats were randomly divided into a control group (no treatment of the defects), PLA group (treated with PLA scaffolds with USCs), and PLA/HA group (treated with PLA/HA scaffolds with USCs). The therapeutic efficacy was evaluated by real-time PCR, microcomputed tomography (micro-CT), and immunohistochemistry at 4, 8, and 12 weeks. We found that the PLA/HA scaffold loaded with USCs effectively promoted new bone regeneration in the defect area. CT images showed that in the PLA/HA group, the defect area was almost entirely covered by newly formed bone (coverage of 96.7 ± 1.6%), and the coverage was greater than that in the PLA group (coverage of 74.6 ± 1.9%) at 12 weeks. Histology and immunohistochemical staining showed the highest new bone formation on the PLA/HA scaffolds containing USCs in the defect site at 12 weeks. These findings demonstrate the broad application prospects of PLA/HA scaffolds with USCs in bone tissue engineering. Graphical abstract.

Abstract
Mesenchymal stem cells (MSCs) are important seed cells for cell therapy and tissue engineering because of their multidirectional differentiation potential, high proliferative capacity, low immunogenicity, and immunomodulatory ability. In this study, we successfully isolated and cultured a population of mesenchymal stem-like cells from pediatric urethra (PU-MSLCs). The cells had a spindle-shaped fibroblast-like morphology, similar to MSCs derived from other tissues. The PU-MSLCs highly expressed MSC surface markers CD29, CD73, CD90, and CD105 but were negative for leukocyte common antigen CD45, and MHC class II-encoded molecule HLA-DR. After in vitro induction, the PU-MSLCs had the potential to differentiate into adipocytes, osteocytes, and chondrocytes. The PU-MSLCs maintained a normal karyotype and showed no tumorigenicity during long-term cultivation. We thus demonstrated that the mesenchymal stem/stromal cell-like population obtained from pediatric urethra tissue is capable of self-renewal and multidirectional differentiation, has promising application prospects for cell therapy and tissue engineering, and is expected to contribute to urethral tissue reconstruction.

Abstract
BACKGROUND Immunoglobulin A (IgA) nephropathy (IgAN) is one of an important cause of progressive kidney disease and occurs when IgA settles in the kidney resulted in disrupts kidney's ability to filter waste and excess water. Hydrogels are promising material for medical applications owing to their excellent adaptability and filling ability. Herein, we proposed a hyaluronic acid/gelatin (CHO-HA/Gel-NH2) bioactive hydrogel as a cell carrier for therapeutic kidney regeneration in IgAN. METHODS CHO-HA/Gel-NH2 hydrogel was fabricated by Schiff-base reaction without any additional crosslinking agents. The hydrogel concentrations and ratios were evaluated to enhance adequate mechanical properties and biocompatibility for further in vivo study. High serum IgA ddY mice kidneys were treated with human urine-derived renal progenitor cells encapsulated in the hydrogel to investigate the improvement of IgA nephropathy and kidney regeneration. RESULTS The stiffness of the hydrogel was significantly enhanced and could be modulated by altering the concentrations and ratios of hydrogel. CHO-HA/Gel-NH2 at a ratio of 3/7 provided a promising milieu for cells viability and cells proliferation. From week four onwards, there was a significant reduction in blood urea nitrogen and serum creatinine level in Cell/Gel group, as well as well-organized glomeruli and tubules. Moreover, the expression of pro-inflammatory and pro-fibrotic molecules significantly decreased in the Gel/Cell group, whereas anti-inflammatory gene expression was elevated compared to the Cell group. CONCLUSION Based on in vivo studies, the renal regenerative ability of the progenitor cells could be further increased by this hydrogel system.

Abstract
OBJECTIVE Stem-cell therapy is a promising treatment for cartilage defects. The newly identified urine-derived stem cells (USCs), which have multipotency and sufficient proliferative ability, are promising candidates for several tissue engineering therapies. In this study, we investigated the role of USC extracellular vehicles (EVs) in promoting the proliferation and migration of chondrocytes. DESIGN USCs were characterized by measuring induced multipotent differentiation and flow cytometry analysis of surface marker expression. The EVs were isolated from USCs under normoxic conditions (nor-EVs) and hypoxic conditions (hypo-EVs). Transmission electron microscopy and western blot analysis characterized the EVs. The chondrocytes were cultured in the USC-EVs. CCK-8 assay and EdU staining detected the proliferation of chondrocytes, and transwell assay detected their migration. miR-26a-5p expression in EVs was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The target relationship of miR-26a-5p and phosphatase and tensin homolog (PTEN) was predicted and confirmed. The roles of EVs-miR-26a-5p and PTEN on the proliferation and migration of chondrocytes were also investigated. RESULTS Hypo-EVs showed a superior effect in promoting the proliferation and migration of chondrocytes than nor-EVs. Mechanistically, USC-EVs delivered miR-26a-5p into chondrocytes to overexpress miR-26a-5p. PTEN was identified as an miR-26a-5p target in chondrocytes. The effects of EVs-miR-26a-5p on promoting the proliferation and migration of chondrocytes were mediated by its regulation of PTEN. CONCLUSION Our study suggested that hypoxic USC-EVs may represent a promising strategy for osteoarthritis by promoting the proliferation and migration of chondrocytes via miR-26a-5p transfer.

Epithelial Sodium Channel Alpha Subunit (αENaC) Is Associated with Inverse Salt Sensitivity of Blood Pressure. Biomedicines 2022; 10:biomedicines10050981.

Abstract
Salt sensitivity of blood pressure (BP) refers to an increase in BP following an increase in dietary salt, which is associated with increased incidence of cardiovascular disease and early death. However, decreased sodium intake also increases mortality and morbidity. Inverse salt sensitivity (ISS), defined as a paradoxical increase in BP on a low-salt diet, about 11% of the population, may be the cause of this phenomenon. The epithelial sodium channel (ENaC) is a major regulator of sodium reabsorption in the kidney. In this study, human renal tubular epithelial cells (hRTC) were cultured from the urine of phenotyped salt study participants. αENaC expression was significantly lower in ISS than salt resistant (SR) hRTC, while ENaC-like channel activity was dramatically increased by trypsin treatment in ISS cells analyzed by patch clamp. αENaC expression was also decreased under high-salt treatment and increased by aldosterone treatment in ISS cells. Moreover, the αENaC variant, rs4764586, was more prevalent in ISS. In summary, αENaC may be associated with ISS hypertension on low salt. These findings may contribute to understanding the mechanisms of ISS and low salt effect on morbidity and mortality.

Abstract
BACKGROUND The generation of induced pluripotent stem cells (iPSC) has been a game-changer in translational and regenerative medicine; however, their large-scale applicability is still hampered by the scarcity of accessible, safe, and reproducible protocols. The porcine model is a large biomedical model that enables translational applications, including gene editing, long term in vivo and offspring analysis; therefore, suitable for both medicine and animal production.
AIM To reprogramme in vitro into pluripotency, and herein urine-derived cells (UDCs) were isolated from porcine urine.
METHODS The UDCs were reprogrammed in vitro using human or murine octamer-binding transcription factor 4 (OCT4), SRY-box2 (SOX2), Kruppel-like factor 4 (KLF4), and C-MYC, and cultured with basic fibroblast growth factor (bFGF) supplementation. To characterize the putative porcine iPSCs three clonal lineages were submitted to immunocytochemistry for alkaline phosphatase (AP), OCT4, SOX2, NANOG, TRA1 81 and SSEA 1 detection. Endogenous transcripts related to the pluripotency (OCT4, SOX2 and NANOG) were analyzed via reverse transcription quantitative real-time polymerase chain reaction in different time points during the culture, and all three lineages formed embryoid bodies (EBs) when cultured in suspension without bFGF supplementation.
RESULTS The UDCs were isolated from swine urine samples and when at passage 2 submitted to in vitro reprogramming. Colonies of putative iPSCs were obtained only from UDCs transduced with the murine factors (mOSKM), but not from human factors (hOSKM). Three clonal lineages were isolated and further cultured for at least 28 passages, all the lineages were positive for AP detection, the OCT4, SOX2, NANOG markers, albeit the immunocytochemical analysis also revealed heterogeneous phenotypic profiles among lineages and passages for NANOG and SSEA1, similar results were observed in the abundance of the endogenous transcripts related to pluripotent state. All the clonal lineages when cultured in suspension without bFGF were able to form EBs expressing ectoderm and mesoderm layers transcripts.
CONCLUSION For the first time UDCs were isolated in the swine model and reprogrammed into a pluripotent-like state, enabling new numerous applications in both human or veterinary regenerative medicine.

Abstract
Stem cells possess regenerative powers and multidirectional differentiation potential and play an important role in disease treatment and basic medical research. Urine-derived stem cells (USCs) represent a newly discovered type of stem cell with biological characteristics similar to those of mesenchymal stromal cells (MSCs), including their doubling time and immunophenotype. USCs are noninvasive and can be readily obtained from voided urine and steadily cultured. Based on advances in this field, USCs and their secretions have increasingly emerged as ideal sources. USCs may play regulatory roles in the cellular immune system, oxidative stress, revascularization, apoptosis and autophagy. This review summarizes the applications of USCs in tissue regeneration and various disease treatments. Furthermore, by analysing their limitations, we anticipate the development of more feasible therapeutic strategies to promote USC-based individualized treatment.

Abstract
Regenerative medicine based on stem cell research has the potential to provide advanced health care for human beings. Recent studies demonstrate that stem cells in human urine can serve as an excellent source of graft cells for regenerative therapy, mainly due to simple, low-cost, and noninvasive cell isolation. These cells, termed human urine-derived stem cells (USCs), are highly expandable and can differentiate into various cell lineages. They share many biological properties with mesenchymal stem cells, such as potent paracrine effects and immunomodulation ability. The advantage of USCs has motivated researchers to explore their applications in regenerative medicine, including genitourinary regeneration, musculoskeletal repair, skin wound healing, and disease treatment. Although USCs have showed many positive outcomes in preclinical studies, and although the possible applications of USCs for animal therapy have been reported, many issues need to be addressed before clinical translation. This article provides a comprehensive review of USC biology and recent advances in their application for tissue regeneration. Challenges in the clinical translation of USC-based therapy are also discussed. Impact statement Recently, stem cells isolated from urine, referred to as urine-derived stem cells (USCs), have gained much interest in the field of regenerative medicine. Many advantages of human USCs have been found for cell-based therapy: (i) the cell isolation procedure is simple and low cost; (ii) they have remarkable proliferation ability, multidifferentiation potential, and paracrine effects; and (iii) they facilitate tissue regeneration in many animal models. With the hope to facilitate the development of USC-based therapy, we describe the current understanding of USC biology, summarize recent advances in their applications, and discuss future challenges in clinical translation.

Abstract
Mesenchymal stem cells (MSCs) represent an attractive source within the field of tissue engineering. However, their harvesting often requires invasive medical procedures. Urine-derived stem cells (UDSCs) display similar properties to MSCs, and their obtention and further processing is non-invasive for the donors as well as low cost. Here, we offer a comprehensive analysis of their biological properties. The goal of this study was to analyze their morphology, stemness, differentiation potential and cytokine profile. We have successfully isolated UDSCs from 25 urine samples. First colonies emerged up to 9 days after the initial seeding. Cell doubling time was 45 ± 0.24 SD, and when seeded at the density of 100 cells/cm2, they formed 42 ± 6.5 SD colonies within 10 days. Morphological analyzes revealed that two different types of the cell populations have been present. The first type had a rice-grain shape and the second one was characterized by a polyhedral shape. In several cell cultures, dome-shaped cells were observed as well. All examined UDSCs expressed typical MSC-like surface markers, CD73, CD90 and CD105. Moreover, conditioned media from UDSCs were harvested, and cytokine profile has been evaluated showing a significantly higher secretory rate of IL-8, IL-6 and chemokines MCP-1 and GM-CSF. We have also successfully induced human UDSCs into chondrogenic, osteogenic and myogenic cell lineages. Our findings indicate that UDSCs might have immense potential in the regeneration of the damaged tissues.

Abstract
Urine-derived stem cells (USCs) are adult stem cells isolated from urine with strong proliferative ability and differentiation potentials. Cell transplantation of USCs could partly repair liver injury. It has been reported that the proliferative ability of bone mesenchymal stem cells in patients with chronic liver failure is significantly lower than in patients without liver disease. The aim of this study was therefore to evaluate the biological characteristics of USCs from end-stage liver disease patients (LD-USCs, USCs from patients with liver disease) compared with those from normal healthy individuals (N-USCs, USCs from normal individuals), with a view to determining whether autologous USCs can be applied to the treatment of liver disease. In this study USCs were isolated from urine samples of male patients with end-stage liver disease. Adherent USCs exhibit a spindle- or rice grain-like morphology, and express CD24, CD29, CD73, CD90, and CD146 surface markers, but not CD31, CD34, CD45, and CD105. We observed no differences in cell morphology or cell surface marker profile between LD-USCs and N-USCs. LD-USCs exhibited similar proliferative, colony-forming, apoptotic, and migratory abilities to N-USCs. Both USCs demonstrated similar capacities for osteogenic, adipogenic, and chondrogenic differentiation. When USCs were transplanted into CCl4 treatment-induced acute and chronic liver fibrosis mouse models, we observed a decrease in liver index, recovery of alanine aminotransferase and aspartate aminotransferase levels, alleviation of liver tissue injury, and dramatic improvement of liver tissue structure. USC transplantation can effectively recover liver function and improve liver tissue damage in acute or chronic liver injury mouse models. According to the results, we concluded that the biological characteristics of LD-USCs are not affected by basic liver disease. This study provides further evidence of the stem cell characteristics and liver repair function of LD-USCs, which may serve as a theoretical and experimental foundation for autologous USC transplantation technology in the treatment of liver failure and end-stage liver diseases.

Molecular Mechanisms of Renal Progenitor Regulation: How Many Pieces in the Puzzle? Cells 2021; 10:cells10010059.

Abstract
Kidneys of mice, rats and humans possess progenitors that maintain daily homeostasis and take part in endogenous regenerative processes following injury, owing to their capacity to proliferate and differentiate. In the glomerular and tubular compartments of the nephron, consistent studies demonstrated that well-characterized, distinct populations of progenitor cells, localized in the parietal epithelium of Bowman capsule and scattered in the proximal and distal tubules, could generate segment-specific cells in physiological conditions and following tissue injury. However, defective or abnormal regenerative responses of these progenitors can contribute to pathologic conditions. The molecular characteristics of renal progenitors have been extensively studied, revealing that numerous classical and evolutionarily conserved pathways, such as Notch or Wnt/β-catenin, play a major role in cell regulation. Others, such as retinoic acid, renin-angiotensin-aldosterone system, TLR2 (Toll-like receptor 2) and leptin, are also important in this process. In this review, we summarize the plethora of molecular mechanisms directing renal progenitor responses during homeostasis and following kidney injury. Finally, we will explore how single-cell RNA sequencing could bring the characterization of renal progenitors to the next level, while knowing their molecular signature is gaining relevance in the clinic.
