Abstract
Background: ANCA-associated vasculitis (AAV) is a rare small vessel disease characterized by multi-organ involvement. Biomarkers that can measure specific organ involvement are missing. Here, we ask whether certain circulating cytokines and chemokines correlate with renal involvement and if distinct cytokine/chemokine patterns can differentiate between renal, ear/nose/throat, joints, and lung involvement of AAV. Methods: Thirty-two sets of Birmingham vasculitis activity score (BVAS), PR3-ANCA titers, laboratory marker, and different cytokines were obtained from 17 different patients with AAV. BVAS, PR3-ANCA titers, laboratory marker, and cytokine concentrations were correlated to different organ involvements in active AAV. Results: Among patients with active PR3-AAV (BVAS > 0) and kidney involvement we found significant higher concentrations of chemokine ligand (CCL)-1, interleukin (IL)-6, IL21, IL23, IL-28A, IL33, monocyte chemoattractant protein 2 (MCP2), stem cell factor (SCF), thymic stromal lymphopoietin (TSLP), and thrombopoietin (TPO) compared to patients without PR3-ANCA-associated glomerulonephritis. Patients with ear, nose, and throat involvement expressed higher concentrations of MCP2 and of the (C-X-C motif) ligand-12 (CXCL-12) compared to patients with active AAV and no involvement of these organs. Conclusion: We identified distinct cytokine patterns for renal manifestation and for ear, nose and throat involvement of PR3-AAV. Distinct plasma cytokines might be used as non-invasive biomarkers of organ involvement in AAV.

Abstract
Stem cell factor (SCF) and its receptor c-kit have been implicated in inflammation, tissue remodeling, and fibrosis. Ingenuity Integrated Pathway Analysis of gene expression array data sets showed an upregulation of SCF transcripts in idiopathic pulmonary fibrosis (IPF) lung biopsies compared with tissue from nonfibrotic lungs that are further increased in rapid progressive disease. SCF248, a cleavable isoform of SCF, was abundantly and preferentially expressed in human lung fibroblasts and fibrotic mouse lungs relative to the SCF220 isoform. In fibroblast-mast cell coculture studies, blockade of SCF248 using a novel isoform-specific anti-SCF248 monoclonal antibody (anti-SCF248), attenuated the expression of COL1A1, COL3A1, and FN1 transcripts in cocultured IPF but not normal lung fibroblasts. Administration of anti-SCF248 on days 8 and 12 after bleomycin instillation in mice significantly reduced fibrotic lung remodeling and col1al, fn1, acta2, tgfb, and ccl2 transcript expression. In addition, bleomycin increased numbers of c-kit+ mast cells, eosinophils, and ILC2 in lungs of mice, whereas they were not significantly increased in anti-SCF248-treated animals. Finally, mesenchymal cell-specific deletion of SCF significantly attenuated bleomycin-mediated lung fibrosis and associated fibrotic gene expression. Collectively, these data demonstrate that SCF is upregulated in diseased IPF lungs and blocking SCF248 isoform significantly ameliorates fibrotic lung remodeling in vivo suggesting that it may be a therapeutic target for fibrotic lung diseases.

Abstract
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. Moreover, paracrine mechanisms could also account for kidney regeneration, either by stimulating proliferation of surviving cells or modulating autophagy and podocyte cytoskeleton rearrangement through mTOR‐Raptor and ‐Rictor signaling, which ultimately lead to morphological and functional improvement. To gain insights into the functional properties of c‐Kit+ cells during kidney development, homeostasis, and disease, studies on lineage tracing using transgenic mice will unveil their fate. The results obtained from these studies will set the basis for establishing further investigation on the therapeutic potential of c‐Kit+ cells for treatment of kidney disease in preclinical and clinical studies. stemcellstranslationalmedicine2018;7:317–324

Abstract
Mast cells (MCs) are derived from committed precursors that leave the hematopoietic tissue, migrate in the blood, and colonize peripheral tissues where they terminally differentiate under microenvironment stimuli. They are distributed in almost all vascularized tissues where they act both as immune effectors and housekeeping cells, contributing to tissue homeostasis. Historically, MCs were classified into 2 subtypes, according to tryptic enzymes expression. However, MCs display a striking heterogeneity that reflects a complex interplay between different microenvironmental signals delivered by various tissues, and a differentiation program that decides their identity. Moreover, tissue-specific MCs show a trained memory, which contributes to shape their function in a specific microenvironment. In this review, we summarize the current state of our understanding of MC heterogeneity that reflects their different tissue experiences. We describe the discovery of unique cell molecules that can be used to distinguish specific MC subsets in vivo, and discuss how the improved ability to recognize these subsets provided new insights into the biology of MCs. These recent advances will be helpful for the understanding of the specific role of individual MC subsets in the control of tissue homeostasis, and in the regulation of pathological conditions such as infection, autoimmunity, and cancer.

Abstract
BACKGROUND AND OBJECTIVES Stem cell factor (SCF), the ligand of the c-kit receptor, actively participates in the organ reconstruction and fibrosis associated with various diseases, including kidney disease. However, it remains unclear whether SCF plays a role in kidney aging. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS In the present study, we measured the serum SCF level, estimated glomerular filtration rate (eGFR), and other biological parameters in a Chinese Han group of 892 subjects, and explored the relationship between SCF level and renal function during aging; we sought to define novel biomarkers of kidney aging. RESULTS Multiple linear regression was used to select potential indicators of decline in renal function. Only age, SCF level, and 25% maximum expiratory flow (25% MEF) were significant predictors after redundancy analysis (|r| > 0.70 and P < 0.05). Multiple linear regression showed that the relationship among eGFR, SCF level, and age could be described as follows: eGFR = 154.486 - (0.846 × age) - (0.011 × SCF level). CONCLUSIONS We found no between-gender difference in the effect of SCF on kidney aging. In conclusion, the SCF level is an ideal biomarker of renal aging and may help to predict changes in eGFR during aging.

Abstract
CD34, traditionally a marker of hematopoietic stem cells (HSCs), was found on endothelial cells and fibroblasts as well. At the level of the extraglomerular or intraglomerular mesangium, CD34 may signal either the presence of HSCs or, conversely, may be a marker of transdifferentiation. CD34-positive cells of the extraglomerular mesangium could migrate into the intraglomerular mesangium and participate in reparative processes at this level. The aim of our study was to analyze the presence of CD34 at the level of the extraglomerular and intraglomerular mesangium and its relationship with histological markers of activity and chronicity, as well as with other immunohistochemical markers in glomerulonephritis (GN). A cross-sectional study of 36 patients with GN was conducted. Conventional stains: hematoxylin-eosin, periodic acid Schiff, and Trichrome Gömöri, as well as immunohistochemistry: CD34, alpha smooth muscle actin (alpha SMA), vimentin, and proliferating cell nuclear antigen (PCNA) were employed. Activity and chronicity of GN were evaluated according to a scoring system initially used for lupus nephritis and antineutrophil-cytoplasmic-antibody-associated vasculitis. Immunohistochemistry was assessed using a semiquantitative score. The mean age was 46.44 +/- 12.97 years; 22 were male and 14 were female. The extraglomerular mesangium was visible on specimens in 30 patients. CD34 was present in the extraglomerular mesangium in 15 patients: 11 of these patients showed concomitant intraglomerular and extraglomerular mesangial CD34 immunostaining, while four showed only extraglomerular mesangial immunostaining. In three patients, CD34 immunostaining was present only in the intraglomerular mesangium. Twelve patients showed negative immunostaining in both the extraglomerular and the intraglomerular mesangium. Overall, there was a fair degree of relationship, which did not reach statistical significance between CD34 in the extraglomerular mesangium and CD34 in the intraglomerular mesangium across the 36 patients. In the intraglomerular mesangium, CD34 did not significantly correlate with mesangial alpha SMA, vimentin, PCNA, and activity or chronicity index. In the extraglomerular mesangium, CD34 did not show a significant correlation with alpha SMA, vimentin, or PCNA. The activity index and the chronicity index showed a good correlation with serum creatinine. Mesangial cell proliferation correlated well with the mesangial matrix increase, while interstitial vimentin showed a good correlation with interstitial alpha SMA. We demonstrated the presence of CD34 in the extraglomerular mesangium, which could be related to transdifferentiated mesangial cells or to HSCs in the absence of blood vessels at this level. Our study shows the value of histological indices for evaluating GN but cannot assign significance to CD34 immunolabeling for the assessment of GN.

Abstract
In the present studies the role of stem cell factor (SCF) in mediating eosinophil and fibroblast activation during their interaction was investigated. SCF was significantly higher in fibroblasts grown from lungs of chronic allergen-challenged mice compared to fibroblasts grown from normal mice. When eosinophils were layered onto fibroblasts from allergic mice, a significant increase in SCF was detected compared to fibroblasts from nonallergic mice. The interaction of fibroblasts with eosinophils also increased the production of asthma-associated chemokines, CCL5 and CCL6, was dependent on cell-to-cell interaction, and was observed only with fibroblasts derived from lungs of chronic allergen-challenged mice and not from those derived from unchallenged normal mice. Chemokine production was significantly decreased when anti-SCF antibodies were added during eosinophil-fibroblast interaction. The interaction of fibroblasts from chronic allergen-challenged mice with eosinophils also increased alpha-smooth muscle cell actin and procollagen I expression as well as induced transforming growth factor-beta. The changes in myofibroblast activation were dependent on SCF-mediated pathways because anti-SCF antibody treatment reduced the expression of all three of these latter fibrosis-associated markers. Thus, our data suggest that SCF mediates an important activation pathway for fibroblasts during chronic allergic responses on interaction with recruited eosinophils and suggest a potential mechanism of airway remodeling during chronic disease.

Abstract
Inflammatory kidney disease involves a complex network of interactions between resident kidney and infiltrating hematopoietic cells. Mast cells (MCs) are constitutively found in kidneys in small numbers but increase considerably in various renal diseases. While this increase is usually interpreted as a sign of pathological involvement, recent data using MC-deficient animals show their ability to restore kidney homeostasis. In anti-glomerular basement membrane antibody-induced glomerulonephritis, MCs are protective by initiating repair and remodeling functions counteracting the devastating effects of glomerular injury. Protection may also include immunoregulatory capacities to limit autoreactive T-cell responses. MCs also control tubulointerstitial fibrosis by activating tissue remodeling and neutralizing fibrotic factors. Release of mediators by MCs during inflammation, however, could also promote unwanted responses that ultimately lead to destruction of kidney structure, as exemplified by data showing either protection or aggravation in related renal disease models. Similarly, while the action of proteases may initially be beneficial, the generation of fibrosis-promoting angiotensin II by chymase also shows the limits of adaptive responses to achieve homeostasis. Thus, it is likely the physiological context involving the interaction with other cells and inflammatory mediators that determines the final action of MCs in the development of kidney disease.

Abstract
Tubulointerstitial fibrosis is a final common pathway to the eventual structural desolation of kidneys. However, the mechanism involved in this phenomenon is still poorly understood, and current therapies are ineffective or only marginally effective. Mast cell has a variety of physiological and pathological functions through the production of heparin, histamine, neutrophil chemoattractants, immunoregulatory cytokines, and mast cell-specific serine proteases tryptase and chymase. The survival and proliferation of mast cell are dependent upon stem cell factor. Presently, mast cells are known to participate in the pathogenesis of tubulointerstitial fibrosis in many kidney diseases. Several therapeutic approaches to inhibit mast cell activation have already demonstrated some clinical utility in tissue fibrosis or inflammatory diseases such as the use of mast cell stabilizers, inhibitors of tryptase or chymase, blockade of stem cell factor and anti-IgE therapy. We hypothesize that mast cell has a significant role in the progression of tubulointerstitial fibrosis, thus the treatment strategies based on mast cell appear to be promising in these conditions. Development of these novel therapeutic approaches will enable us to target any types of renal disease.

Abstract
Although glomerulonephritis and renal failure have been observed after allogenic stem cell transplantation, only a few such reports were published about patients undergoing autologous stem cell transplantation. We report a case of mesangial proliferative glomerulonephritis developing 4 months after autologous stem cell transplantation for chronic lymphatic leukemia. Serological test results, together with histological, immunohistochemical, and electronic microscopic findings of a kidney biopsy specimen, confirmed the diagnosis of mesangial proliferative glomerulonephritis in our patient. Complement and immunoglobulin A were not present in the kidney biopsy specimen. An abnormal clone, not previously reported, with the translocation t(5;11)(q31;q13) in blood and bone marrow was observed. The reason for and whether progenitor cells in stem cell transplantations could contribute to the development of glomerulonephritis remain open questions. Kidney biopsy should be performed in patients with microscopic hematuria and/or proteinuria after autologous stem cell transplantation.

Abstract
Mast cells are detrimental in several inflammatory diseases; however, their physiological roles are also increasingly recognized. Recent data suggest that mast cells may also be involved in renal diseases. We therefore used congenitally mast cell-deficient W/W(v) mice and normal +/+ littermates to assess their role in anti-glomerular basement membrane-induced glomerulonephritis. Following administration of anti-glomerular basement membrane Abs, W/W(v) mice exhibited increased mortality as compared with +/+ mice owing to rapid deterioration of renal function. Reconstitution of the mast cell population in W/W(v) mice restored protection. This was independent of activating FcgammaR, as protection was also obtained using mast cells deficient in FcRgamma. Comparative histological analysis of kidneys showed that deterioration of renal function was caused by the presence of thick layers of subendothelial glomerular deposits in W/W(v) mice, while +/+ mice or mast cell-reconstituted W/W(v) mice showed significantly less. Deposits appeared during the early phase of disease and persisted thereafter, and were accompanied by enhanced macrophage recruitment. Immunohistochemical analysis revealed increased amounts of fibrin and type I collagen in W/W(v) mice, which were also unable to maintain high tissue plasminogen activator and urinary-type plasminogen activator activity in urine in the heterologous phase of disease. Our results indicate that mast cells by their ability to mediate remodeling and repair functions are protective in immune complex-mediated glomerulonephritis.

Abstract
Mast cells infiltrate kidneys of humans with crescentic glomerulonephritis (GN), and the degree of infiltrate correlates with outcome. However, a functional role for mast cells in the pathogenesis of GN remains speculative. GN was induced by intravenous administration of sheep anti-mouse glomerular basement membrane globulin. After 21 d, systemic immune responses and disease severity were analyzed in wild-type, mast cell-deficient (W/Wv), and bone marrow-derived mast cell-reconstituted W/Wv mice (BMMC-->W/Wv). There were no significant differences in the humoral response toward the nephritogenic antigen or in memory T cell number among the three groups; however, antigen-stimulated T cell IFN-gamma production was significantly elevated in BMMC-->W/Wv mice. Dermal delayed-type hypersensitivity in W/Wv mice was reduced compared with wild-type and BMMC-->W/Wv mice. No mast cells were detected in kidneys of W/Wv mice with GN, whereas in BMMC-->W/Wv mice, the numbers of renal mast cells were similar to wild-type mice with GN. W/Wv mice were protected from the development of crescentic GN, exhibiting reduced crescent formation (10 +/- 1% c.f. 36 +/- 2% in wild type), glomerular influx of T cells/macrophages, and interstitial infiltrate compared with wild-type mice. In contrast, BMMC-->W/Wv demonstrated a similar severity of GN as wild-type mice (35 +/- 2% crescentic glomeruli), accompanied by a prominent inflammatory cell infiltrate into glomeruli and interstitial areas. Glomerular expression of intercellular adhesion molecule-1 and P-selectin were reduced in W/Wv mice but restored to wild-type levels in BMMC-->W/Wv mice. These findings suggest that renal mast cells mediate crescentic GN by facilitating effector cell recruitment into glomeruli via augmentation of adhesion molecule expression.

Abstract
There has been considerable focus on the ability of bone marrow-derived cells to differentiate into non-haematopoietic cells of various tissue lineages, including cells of the kidney. This growing evidence has led to a reconsideration of the source of cells contributing to renal repair following injury. The kidney has an inherent ability for recovery and regeneration following acute damage. It is thought that dedifferentiation of glomerular and tubular cells to a more embryonic/mesenchymal phenotype represent key processes for recovery in response to damage. However, there has been much contention as to the source of regenerating renal cells. The present review focuses on new aspects of the plasticity of intrinsic renal cells and their role in renal remodelling and scarring. Growing support also suggests that bone marrow-derived cells have the ability to contribute to structural and functional repair following acute renal failure. Evidence for bone marrow cell engraftment in the repairing kidney leading to incorporation into a variety of tissue types is discussed. Because cell death and fibrosis is a common end-point in a variety of acute and chronic renal nephropathies, the paradigm of stem cell plasticity may have important implications in the cellular and pathological mechanisms of renal injury and repair. A better understanding of the processes controlling extra-renal cell engraftment and intrinsic renal cell differentiation may provide important clues for the development of new cell-based therapies in the field of renal reparative medicine.

Abstract
The progression of renal scarring and the associated loss of function remains one of the main challenges in nephrology. Until recently, the glomerular and tubulointerstitial scarring processes were thought to involve primarily interactions between infiltrating inflammatory cells and resident renal cells culminating in loss of renal cells and their replacement by extracellular collagenous matrix (ECM). This review focuses on new aspects of renal response to injury and remodeling. Emphasis is on the plasticity of renal cells with the capacity of both glomerular and tubular cells to assume a range of phenotypes during the remodeling process. Both glomerular and tubular epithelial cells regress to primitive/embryonic mesenchymal phenotype in response to injury. This reverse embryogenesis is a key step in renal healing and scarring. In addition to the plasticity of intrinsic renal cells, it is becoming apparent that renal remodeling in health and disease involves the migration of progenitor hematopoietic stem cells into the kidneys. These cells assume various glomerular and tubular epithelial phenotype. They are also involved in the evolution of lesions toward healing or scarring. A better understanding of some of these key events in renal remodeling and their mediators may open the way to new interventions based on their manipulations and aimed at favoring renal healing and preventing scarring.
