Abstract
A novel avenue for advancing our understanding of kidney disease mechanisms and developing targeted therapeutics lies in overcoming the limitations of the existing in vitro models. Traditional animal models, while useful, do not fully capture the intricacies of human kidney physiology and pathophysiology. Tissue engineering offers a promising solution, yet current models often fall short in replicating the complex microarchitecture and biochemical milieu of the kidney. To address this challenge, we propose the development of a sophisticated in vitro glomerular filtration barrier (GFB) utilizing advanced biomaterials and a kidney decellularized extracellular matrix (kdECM). In our approach, we employ a bacterial cellulose membrane (BC) as a scaffold, providing a robust framework for cell growth and interaction. Coating this scaffold with kdECM hydrogel derived from caprine kidney tissue via a detergent-free decellularization method ensures the preservation of vital extracellular matrix proteins crucial for cellular compatibility and signaling. Our engineered GFB not only supports the growth of endothelial and podocyte cells but also exhibits the presence of key markers such as CD31 and nephrin, indicating successful cellular integration. Furthermore, the expression of collagen IV, an essential extracellular matrix (ECM) protein, validates the fidelity of our model in simulating cellular interactions within a kdECM matrix. Additionally, we assessed the filtration efficiency of the developed GFB model using albumin, a standard protein, to evaluate its performance under conditions that closely mimic the native physiological environment. This innovative approach, which faithfully recapitulates the native microenvironment of the glomerulus, holds immense promise for elucidating kidney disease mechanisms, conducting permeability studies, and advancing personalized therapeutic strategies. By leveraging cutting-edge biomaterials and tissue-specific coculture technology, this study can be further extended to develop GFB for the treatment of renal diseases, ultimately improving patient outcomes and quality of life.

Abstract
Background: Chronic kidney disease (CKD) poses a global health challenge, and it needs alternative therapeutic approaches for patients with end-stage renal disease (ESRD). Although organ transplantation is effective, it faces challenges such as declining quality of life, immunological responses, transplant rejection, and donor shortages. Tissue engineering, by using suitable scaffolds, cells, and growth factors, emerges as a promising treatment option for kidney regeneration. Experiment: We precisely decellularized scaffold, derived from rat kidneys while maintaining its native three-dimensional (3D) architecture. The efficiency of decellularization was evaluated through histological examinations, including hematoxylin and eosin, periodic acid-Schiff, and DAPI staining, as well as scanning electron microscopy. The scaffolds were then recellularized with kidney mesenchymal stem cells (kMSCs), and their adhesion, proliferation, and differentiation were assessed over 1, 2, and 3 weeks. The expression of specific renal markers, including Wt-1, ZO-1, AQP-1, and ANG-1, was examined through quantitative reverse transcription-polymerase chain reaction (qRT-PCR) in monolayer and 3D cultures. Results: The infiltration rate of cells into the scaffold increased in a time-dependent manner, and the expression of specific renal markers significantly increased, demonstrating successful differentiation of kMSCs within the scaffold. The application of basic fibroblast growth factor (bFGF) could intensify the expression of kidney-specific genes. Conclusions: The study highlighted the importance of preserving the 3D architecture of the scaffold during decellularization to achieve optimal cellular responses. Moreover, the capacity of mesenchymal stem cells in recellularized scaffolds facilitated tissue regeneration.

Sustained in vivo perfusion of a re-endothelialized tissue engineered kidney graft in a human-scale animal model. Front Bioeng Biotechnol 2023; 11:1184408. [PMID: 37388767 PMCID: PMC10307518 DOI: 10.3389/fbioe.2023.1184408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 05/25/2023] [Indexed: 07/01/2023] Open
Abstract
Introduction: Despite progress in whole-organ decellularization and recellularization, maintaining long-term perfusion in vivo remains a hurdle to realizing clinical translation of bioengineered kidney grafts. The objectives for the present study were to define a threshold glucose consumption rate (GCR) that could be used to predict in vivo graft hemocompatibility and utilize this threshold to assess the in vivo performance of clinically relevant decellularized porcine kidney grafts recellularized with human umbilical vein endothelial cells (HUVECs). Materials and methods: Twenty-two porcine kidneys were decellularized and 19 were re-endothelialized using HUVECs. Functional revascularization of control decellularized (n = 3) and re-endothelialized porcine kidneys (n = 16) was tested using an ex vivo porcine blood flow model to define an appropriate metabolic glucose consumption rate (GCR) threshold above which would sustain patent blood flow. Re-endothelialized grafts (n = 9) were then transplanted into immunosuppressed pigs with perfusion measured using angiography post-implant and on days 3 and 7 with 3 native kidneys used as controls. Patent recellularized kidney grafts underwent histological analysis following explant. Results: The glucose consumption rate of recellularized kidney grafts reached a peak of 39.9 ± 9.7 mg/h at 21 ± 5 days, at which point the grafts were determined to have sufficient histological vascular coverage with endothelial cells. Based on these results, a minimum glucose consumption rate threshold of 20 mg/h was set. The revascularized kidneys had a mean perfusion percentage of 87.7% ± 10.3%, 80.9% ± 33.1%, and 68.5% ± 38.6% post-reperfusion on Days 0, 3 and 7, respectively. The 3 native kidneys had a mean post-perfusion percentage of 98.4% ± 1.6%. These results were not statistically significant. Conclusion: This study is the first to demonstrate that human-scale bioengineered porcine kidney grafts developed via perfusion decellularization and subsequent re-endothelialization using HUVEC can maintain patency with consistent blood flow for up to 7 days in vivo. These results lay the foundation for future research to produce human-scale recellularized kidney grafts for transplantation.

Abstract
Organ decellularization creates cell-free, collagen-based extracellular matrices that can be used as scaffolds for tissue engineering applications. This technique has recently gained much attention, yet adequate scaffold repopulation and implantation remain a challenge. Specifically, there still needs to be a greater understanding of scaffold responses post-transplantation and ways we can improve scaffold durability to withstand the in vivo environment. Recent studies have outlined vascular events that limit organ decellularization/recellularization scaffold viability for long-term transplantation. However, these insights have relied on in vitro/in vivo approaches that need enhanced spatial and temporal resolutions to investigate such issues at the microvascular level. This study uses intravital microscopy to gain instant feedback on their structure, function, and deformation dynamics. Thus, the objective of this study was to capture the effects of in vivo blood flow on the decellularized glomerulus, peritubular capillaries, and tubules after autologous and allogeneic orthotopic transplantation into rats. Large molecular weight dextran molecules labeled the vasculature. They revealed substantial degrees of translocation from glomerular and peritubular capillary tracks to the decellularized tubular epithelium and lumen as early as 12 h after transplantation, providing real-time evidence of the increases in microvascular permeability. Macromolecular extravasation persisted for a week, during which the decellularized microarchitecture was significantly and comparably compromised and thrombosed in both autologous and allogeneic approaches. These results indicate that in vivo multiphoton microscopy is a powerful approach for studying scaffold viability and identifying ways to promote scaffold longevity and vasculogenesis in bioartificial organs.

Abstract
Background: In end-stage chronic liver disease, transplantation represents the only curative option. However, the shortage of donors results in the death of many patients. To overcome this gap, it is mandatory to develop new therapeutic options. In the present study, we decellularised pig livers and reseeded them with allogeneic porcine mesenchymal stromal cells (pMSCs) to understand whether extracellular matrix (ECM) can influence and/or promote differentiation into hepatocyte-like cells (HLCs). Methods: After decellularisation with SDS, the integrity of ECM-scaffolds was examined by histological staining, immunofluorescence and scanning electron microscope. DNA quantification was used to assess decellularisation. pMSCs were plated on scaffolds by static seeding and maintained in in vitro culture for 21 days. At 3, 7, 14 and 21 days, seeded ECM scaffolds were evaluated for cellular adhesion and growth. Moreover, the expression of specific hepatic genes was performed by RT-PCR. Results: The applied decellularisation/recellularisation protocol was effective. The number of seeded pMSCs increased over the culture time points. Gene expression analysis of seeded pMSCs displayed a weak induction due to ECM towards HLCs. Conclusions: These results suggest that ECM may address pMSCs to differentiate in hepatocyte-like cells. However, only contact with liver-ECM is not enough to induce complete differentiation.

Abstract
Aim: This study aims to compare the efficacy of tissue engineering for kidney reconstruction. Materials & methods: We searched MEDLINE, EMBASE (May 2021), and reference lists of review articles. Results: 19 articles matched our inclusion criteria. A range of natural, synthetic and hybrid scaffolds with or without incorporating cells/growth factors was investigated in 937 animals. More favorable results were observed with a combination of two or more biomaterials, addition of bioactive moieties, and cell seeding. Creatinine concentration, PAX2, collagen type-1, α-SMA, vimentin, IL-1, IL-6 and TNF-α gene expressions were significantly increased compared with native control. Conclusion: Tissue engineering can improve renal function and regeneration; however, further research could benefit from using hybrid scaffolds, stem cells and large animal models.

Abstract
Vascular diseases contribute to intensive and irreversible damage, and current treatments include medications, rehabilitation, and surgical interventions. Often, these diseases require some form of vascular replacement therapy (VRT) to help patients overcome life-threatening conditions and traumatic injuries annually. Current VRTs rely on harvesting blood vessels from various regions of the body like the arms, legs, chest, and abdomen. However, these procedures also produce further complications like donor site morbidity. Such common comorbidities may lead to substantial pain, infections, decreased function, and additional reconstructive or cosmetic surgeries. Vascular tissue engineering technology promises to reduce or eliminate these issues, and the existing state-of-the-art approach is based on synthetic or natural polymer tubes aiming to mimic various types of blood vessel. Burgeoning decellularization techniques are considered as the most viable tissue engineering strategy to fill these gaps. This review discusses various approaches and the mechanisms behind decellularization techniques and outlines a simplified model for a replacement vascular unit. The current state-of-the-art method used to create decellularized vessel segments is identified. Also, perspectives on future directions to engineer small- (inner diameter >1 mm and <6 mm) to large-caliber (inner diameter >6 mm) vessel substitutes are presented.

Abstract
Background Since human fetal liver progenitor cells (hFLPC) can differentiate into multiple liver cell types in vitro and in vivo, hFLPC may be a suitable source for cell therapy and regeneration strategies. Imperative for effective clinical applications of hFLPC is the enhanced knowledge of growth factors that mediate and improve migration and proliferation. The canonical wingless/int-1 (Wnt) signal transduction pathway is known to play a key role in proliferation and migration of stem cells. So, we investigated a role for Wnt3a and Wnt5a ligands in regulating the proliferation and migration of hFLPC. Methods We used alamarBlue assay and transwell migration assay and examined proliferation and migration of hFLPC to Wnt3a and Wnt5a. In addition, the target genes of Wnt signal transduction pathway was identified using microarray analysis and validated by quantitative real-time polymerase chain reaction (qPCR). Results We found that Wnt3a or Wnt5a independently significantly increased migration and proliferation in a dose-dependent manner which was significantly inhibited by Wnt inhibitors Wnt-C59 or KN-62. Addition of Wnt3a to hFLPC resulted in increased mRNA expression of the known Wnt target genes Axin-2, DKK2, while Wnt5a increased CXCR7, all of which are closely associated with an enhanced proliferation capacity of stem cells. Conclusions Thus, we report that Wnt3a and Wnt5a may play an important role in the proliferation and migration of hFLPC by possibly regulating key target genes-involved in these processes. Incorporating recombinant human Wnt3a and Wnt5a in regenerative strategies using liver stem/progenitor cells might improve the process of liver regeneration.

Abstract
AIMS Regeneration of discarded human kidneys has been considered as an ideal approach to overcome organ shortage for the end-stage renal diseases (ESRDs). The aim of this study was to develop an effective method for preparation of kidney scaffolds that retain the matrix structure required for proliferation and importantly, differentiation of human adipose-derived mesenchymal stem cells (hAd-MSCs) into renal cells. MAIN METHODS we first compared two different methods using triton X-100 and sodium dodecyl sulfate (SDS) for human kidney decellularization; and characterized developed human renal extracellular matrix (ECM) scaffolds. Then, hAd-MSCs were seeded on human decellularized kidney scaffolds and cultured for up to 3 weeks. Next, viability, proliferation, and migration of seeded hAd-MSCs within the scaffolds, underwent histological and scanning electron microscopy (SEM) assessments. Moreover, differentiation of hAd-MSCs into kidney-specific cell types was examined using immunohistochemistry (IHC) staining and qRT-PCR. KEY FINDINGS Our results indicated that triton X-100 was a more effective detergent for decellularization of human kidneys compared with SDS. Moreover, attachment and proliferation of hAd-MSCs within the recellularized human kidney scaffolds, were confirmed. Seeded cells expressed epithelial and endothelial differentiation markers, and qRT-PCR results indicated increased expression of platelet and endothelial cell adhesion Molecule 1 (PECAM-1), paired box 2 (PAX2), and e-cadherine (E-CDH) as factors required for differentiation of hAd-MSCs into epithelial and endothelial cells. SIGNIFICANCE These observations indicate effectiveness of decellularization by triton X-100 to generate suitable human ECM renal scaffolds, which supported adhesion and proliferation of hAd-MSCs and could induce their differentiation towards a renal lineage.

Tissue decellularization has rapidly developed to be a practical approach in tissue engineering research; biological tissue is cleared of cells resulting in a protein-rich husk as a natural scaffold for growing transplanted cells as a donor organ therapy. Minimally processed, acellular extracellular matrix reproduces natural interactions with cells in vitro and for tissue engineering applications in animal models. There are many decellularization techniques that achieve preservation of molecular profile (proteins and sugars), microstructure features such as organization of ECM layers (interstitial matrix and basement membrane) and organ level macrofeatures (vasculature and tissue compartments). While structural and molecular cues receive attention, mechanical and material properties of decellularized tissues are not often discussed. The effects of decellularization on an organ depend on the tissue properties, clearing mechanism, chemical interactions, solubility, temperature, and treatment duration. Physical characterization by a few labs including work from the authors provides evidence that decellularization protocols should be tailored to specific research questions. Physical characterization beyond histology and immunohistochemistry of the decellularized matrix (dECM) extends evaluation of retained functional features of the original tissue. We direct our attention to current technologies that can be employed for structure function analysis of dECM using underutilized tools such as atomic force microscopy (AFM), cryogenic electron microscopy (cryo-EM), dynamic mechanical analysis (DMA), Fourier-transform infrared spectroscopy (FTIR), mass spectrometry, and rheometry. Structural imaging and mechanical functional testing combined with high-throughput molecular analyses opens a new approach for a deeper appreciation of how cellular behavior is influenced by the isolated microenvironment (specifically dECM). Additionally, the impact of these features with different decellularization techniques and generation of synthetic material scaffolds with desired attributes are informed. Ultimately, this mechanical profiling provides a new dimension to our understanding of decellularized matrix and its role in new applications.

Rizki-Safitri A, Traitteur T, Morizane R. Bioengineered Kidney Models: Methods and Functional Assessments. FUNCTION 2021; 2:zqab026. [PMID: 35330622 PMCID: PMC8788738 DOI: 10.1093/function/zqab026] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 05/04/2021] [Accepted: 05/06/2021] [Indexed: 01/06/2023] Open
Abstract
Investigations into bioengineering kidneys have been extensively conducted owing to their potential for preclinical assays and regenerative medicine. Various approaches and methods have been developed to improve the structure and function of bioengineered kidneys. Assessments of functional properties confirm the adequacy of bioengineered kidneys for multipurpose translational applications. This review is to summarize the studies performed in kidney bioengineering in the past decade. We identified 84 original articles from PubMed and Mendeley with keywords of kidney organoid or kidney tissue engineering. Those were categorized into 5 groups based on their approach: de-/recellularization of kidney, reaggregation of kidney cells, kidney organoids, kidney in scaffolds, and kidney-on-a-chip. These models were physiologically assessed by filtration, tubular reabsorption/secretion, hormone production, and nephrotoxicity. We found that bioengineered kidney models have been developed from simple cell cultures to multicellular systems to recapitulate kidney function and diseases. Meanwhile, only about 50% of these studies conducted functional assessments on their kidney models. Factors including cell composition and organization are likely to alter the applicability of physiological assessments in bioengineered kidneys. Combined with recent technologies, physiological assessments importantly contribute to the improvement of the bioengineered kidney model toward repairing and refunctioning the damaged kidney.

Kidney tissue engineering using a well-preserved acellular rat kidney scaffold and mesenchymal stem cells. VETERINARY RESEARCH FORUM : AN INTERNATIONAL QUARTERLY JOURNAL 2021; 12:339-348. [PMID: 34815846 PMCID: PMC8576151 DOI: 10.30466/vrf.2019.104640.2491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/03/2019] [Accepted: 09/14/2019] [Indexed: 11/29/2022]
Abstract
The aim of this study was to acquire an effective method for preparation of rat decellularized kidney scaffolds capable of supporting proliferation and differentiation of human adipose tissue derived mesenchymal stem cells (AD-MSCs) into kidney cells. We compared two detergents, the sodium dodecyl sulfate (SDS) and triton X-100 for decellularization. The efficiency of these methods was assessed by Hematoxylin and Eosin (H&E), 4', 6 diamidino-2-phenylindole and immunohistochemistry (IHC) staining. In the next step, AD-MSCs were seeded into the SDS-treated scaffolds and assessed after three weeks of culture. Proliferation and differentiation of AD-MSCs into kidney-specific cell types were then analyzed by H&E and IHC staining. The histological examinations revealed that SDS was more efficient in removing kidney cells at all-time points compared to triton X-100. Also, in the SDS-treated sections the native extracellular matrix was more preserved than the triton-treated samples. Laminin was completely preserved during decellularization procedure using SDS. Cell attachment in the renal scaffold was observed after recellularization. Furthermore, differentiation of AD-MSCs into epithelial and endothelial cells was confirmed by expression of Na-K ATPase and vascular endothelial growth factor receptor 2 (VEGFR-2) in seeded rat renal scaffolds, respectively. Our findings illustrated that SDS was more effective for decellularization of rat kidney compared to triton X-100. We presented an optimized method for decellularization and recellularization of rat kidneys to create functional renal natural scaffolds. These natural scaffolds supported the growth of AD-MSCs and could also induce differentiation of these cells into epithelial and endothelial cells.

Abstract
BACKGROUND Renal fibrosis occurs largely through epithelial-mesenchymal transition (EMT). This study explored the beneficial effects of a human umbilical cord mesenchymal stem cell-loaded decellularized kidney scaffold (ucMSC-DKS) on renal fibrosis in a rodent model of post-transplantation renal failure, and the underlying mechanism. METHODS Rat-derived DKSs were examined after preparation, and then recellularized with human ucMSCs to prepare cell-loaded patches. A rat model of renal failure was established after subtotal nephrectomy (STN). The cell patches were transplanted to remnant kidneys. Changes in renal function, histology, EMT, and proteins related to the transforming growth factor-β (TGF-β)/Smad signaling pathway in the remnant kidneys were examined 8 weeks after surgery, compared with non-cell patch controls. RESULTS The DKSs were acellular and porous, with rich cytokine and major extracellular matrix components. The ucMSCs were distributed uniformly in the DKSs. Renal function was improved, renal fibrosis and EMT were reduced, and the TGF-β/Smad signaling pathway was inhibited compared with controls at 8 weeks after ucMSC-DKS patch transplantation. CONCLUSIONS The ucMSC-DKS restores renal function and reduces fibrosis by reducing EMT via the TGF-β/Smad signaling pathway in rats that have undergone STN. It provides an alternative for renal fibrosis treatment.

Abstract
The mechanism upon which human kidneys undergo regeneration is debated, though different lineage-tracing mouse models have tried to explain the cellular types and the mechanisms involved. Different sources of human renal progenitors have been proposed, but it is difficult to argue whether these populations have the same capacities that have been described in mice. Using the nephrosphere (NS) model, we isolated the quiescent population of adult human renal stem-like PKHhigh/CD133+/CD24− cells (RSC). The aim of this study was to deepen the RSC in vitro multipotency capacity. RSC, not expressing endothelial markers, generated secondary nephrospheres containing CD31+/vWf+ cells and cytokeratin positive cells, indicating the coexistence of endothelial and epithelial commitment. RSC cultured on decellularized human renal scaffolds generated endothelial structures together with the proximal and distal tubular structures. CD31+ endothelial committed progenitors sorted from nephrospheres generated spheroids with endothelial-like sprouts in Matrigel. We also demonstrated the double commitment toward endothelial and epithelial lineages of single RSC. The ability of the plastic RSC population to recapitulate the development of tubular epithelial and endothelial renal lineages makes these cells a good tool for the creation of organoids with translational relevance for studying the parenchymal and endothelial cell interactions and developing new therapeutic strategies.

Abstract
Background Organoids play an important role in basic research, drug screening, and regenerative medicine. Here, we aimed to develop a novel kind of three-dimensional (3D) organoids generated from urine-derived stem cells (USCs) and to explore whether kidney-specific extracellular matrix (kECM) could enable such organoids for renal function in vitro. Methods USCs were isolated from human urine samples and cultured with kECM extraction to generate 3D organoids in vitro. Eight densities from 1000 to 8000 cells per organoids were prepared, and both ATP assay and Live/Dead staining were used to determine the optimal USC density in forming organoids and kECM additive concentration. The morphology and histology of as-made organoids were evaluated by hematoxylin and eosin (H.E.) staining, immunofluorescence staining and whole mount staining. Additionally, RT-qPCR was implemented to detect renal-related gene expression. Drug toxicity test was conducted to evaluate the potential application for drug screening. The renal organoids generated from whole adult kidney cells were used as a positive control in multiple assessments. Results The optimized cell density to generate ideal USC-derived organoids (USC-organoids) was 5000 cells/well, which was set as applying density in the following experiments. Besides, the optimal concentration of kECM was revealed to be 10%. On this condition, Live/Dead staining showed that USC-organoids were well self-organized without significant cell death. Moreover, H.E. staining showed that compact and viable organoids were generated without obvious necrosis inside organoids, which were very close to renal organoids morphologically. Furthermore, specific proximal tubule marker Aquaporin-1 (AQP1), kidney endocrine product erythropoietin (EPO), kidney glomerular markers Podocin and Synaptopodin were detected positively in USC-organoids with kECM. Nephrotoxicity testing showed that aspirin, penicillin G, and cisplatin could exert drug-induced toxicity on USC-organoids with kECM. Conclusions USC-organoids could be developed from USCs via an optimal procedure. Combining culture with kECM, USC-organoid properties including morphology, histology, and specific gene expression were identified to be similar with real renal organoids. Additionally, USC-organoids posed kECM in vitro showed the potential to be a drug screening tool which might take the place of renal organoids to some extent in the future.

Feng H, Xu Y, Luo S, Dang H, Liu K, Sun WQ. Evaluation and preservation of vascular architectures in decellularized whole rat kidneys. Cryobiology 2020; 95:72-79. [PMID: 32526236 DOI: 10.1016/j.cryobiol.2020.06.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2020] [Revised: 06/01/2020] [Accepted: 06/02/2020] [Indexed: 01/22/2023]
Abstract
Organ transplantation is the gold standard treatment for end-stage organ failure. Due to the severe shortage of transplantable organs, only a tiny fraction of patients may receive timely organ transplantation every year. Decellularization-recellularization technology using allogeneic and xenogeneic organs is currently conceived to be a promising solution to generate functionally transplantable organs in vitro. This approach, however, still faces tremendous technological challenges, one of them being the ability to evaluate and preserve the integrity of vascular architectures upon decellularization and cryostorage of the whole organ matrices so that the off-the-shelf organ grafts are available on demand for clinical applications. In the present study, we report a Micro-CT imaging method for evaluating the integrity of vasculature of the decellularized whole organ scaffolds with/without freezing/thawing. The method uses radiopaque Microfil perfusion and x-ray fluoroscopy to acquire high-resolution angiography of the organ matrix. The whole rat kidney is decellularized using a new multistep perfusion protocol with the combined use of Triton X-100 and DNase. The decellularized kidney matrix is then cryopreserved after the pretreatment with different cryoprotectant solutions. The reconstructed tomographic images from Micro-CT confirm various structural alterations in the vasculature of the whole decellularized kidney matrix with/without frozen storage. The freezing damage to the vascular architectures can be reduced by perfusing cryoprotectant solutions into the whole kidney matrix. Ice-free cryopreservation with the vitrification solution VS83 can successfully preserve the integrity of the whole kidney matrix's vasculature after frozen storage.

A Comparative Study of the Effects of Different Decellularization Methods and Genipin-Cross-Linking on the Properties of Tracheal Matrices. Tissue Eng Regen Med 2018; 16:39-50.

Abstract
Background Different decellularization methods can affect the integrity and the biomechanical and biocompatible properties of the tracheal matrix. Natural cross-linking with genipin can be applied to improve those properties. The goals of this study were to evaluate the effects of different decellularization methods on the properties of genipin-cross-linked decellularized tracheal matrices in rabbits. Methods The tracheas of New Zealand rabbits were decellularized by the Triton-X 100-processed method (TPM) and the detergent-enzymatic method (DEM) and were then cross-linked with genipin. Mechanical tests, haematoxylin-eosin staining, Masson trichrome staining, Safranin O staining, DAPI staining, scanning electronic microscopy (SEM), and biocompatibility tests were used to evaluate the treatment. The bioengineered trachea and control trachea were then implanted into allogeneic rabbits for 30 days. The structural and functional analyses were performed after transplantation. Results The biomechanical tests demonstrated that the biomechanical properties of the decellularized tracheas decreased and that genipin improved them (p < 0.05). The histological staining results revealed that most of the mucosal epithelial cells were removed and that the decellularized trachea had lower immunogenicity than the control group. The analysis of SEM revealed that the decellularized trachea retained the micro- and ultra-structural architectures of the trachea and that the matrices cross-linked with genipin were denser. The biocompatibility evaluation and in vivo implantation experiments showed that the decellularized trachea treated with the DEM had better biocompatibility than that treated with the TPM and that immunogenicity in the cross-linked tissues was lower than that in the uncross-linked tissues (p < 0.05). Conclusions Compared with the trachea treated with the TPM, the rabbit trachea processed by the DEM had better biocompatibility and lower immunogenicity, and its structural and mechanical characteristics were effectively improved after the genipin treatment, which is suitable for engineering replacement tracheal tissue.

Abstract
In recent years, rapid development of tissue engineering technology provides possibilities for the construction of artificial tissues or organs. In construction of engineered kidneys, researchers used native decellularized extracellular matrix (ECM) as the scaffolds to recellularization. However, thrombosis has been a great issue that hinders the progress of transplantation in vivo. In this study, heparin was immobilized to the collagen part of decellularized scaffold with collagen-binding peptide (CBP). Through the anticoagulant and endothelial cell reperfusion experiments, it can be demonstrated that the heparinized scaffolds absorbed less platelets and red blood cells which can effectively reduce the formation of thrombosis. Moreover, it is conducive to long-term adhesion of endothelial cells which is important for the formation of subsequent vascularization. Taken together, our results reveal that the whole kidney can be modified by CBP-heparin composite to reduce the thrombosis and provide the better conditions for neovascularization.

Abstract
Whole kidney decellularization is a promising approach in regenerative medicine for engineering a functional organ. The reaction of the potential host depends on the biocompatibility of these decellularized constructs. Despite the proven ability of decellularized kidney scaffolds to guide cell attachment and growth, little is known about biocompatibility and hemocompatibility of these scaffolds. Our aim is to prepare decellularized kidneys of a clinically relevant size and evaluate its biocompatibility and hemocompatibility. Porcine kidneys were cannulated via the renal artery, and then perfused with 0.1% sodium dodecyl sulfate solution. Hematoxylin and eosin as well as DAPI staining confirmed cellular clearance from native kidneys in addition to preservation of the microstructure. SEM confirmed the absence of any cellular content within the scaffold, which is maintained in a well-organized 3D architecture. Decellularized kidneys retained the intact renal vasculature upon examination with contrast radiography. The essential structural extracellular matrix molecules were well-preserved. Scaffolds were susceptible to enzymatic degradation upon collagenase treatment. Scaffolds showed a good hemocompatibility when exposed to porcine blood. Decellularization was efficient to remove 97.7% of DNA from native kidneys in addition to the immunogenic and pathogenic antigens. Scaffolds did not induce the human immune response in vitro. Decellularized kidneys were non-cytotoxic to pig kidney cells (PKs). PKs were able to grow and proliferate within the decellularized renal scaffolds with maintaining a higher function than cells grown as monolayers. Thus, we have developed a rapid decellularization technique for generating biocompatible kidney scaffolds that represents a step toward development of a transplantable organ. © 2018 Wiley Periodicals, Inc.

Abstract
In end-stage chronic kidney disease, the option of organ transplantation is limited because of the scarce availability of kidneys. The combination of stem cell research, regenerative medicine, and tissue engineering seems a promising approach to produce new transplantable kidneys. Currently, the possibility to repopulate naturally obtained scaffolds with cells of different sources is advancing. Our aim was to test, for the first time, whether the nephrosphere (NS) cells, composed by renal stem/progenitor-like cells, were able to repopulate different nephron portions of renal extracellular matrix scaffolds obtained after decellularization of human renal tissue slices. Our decellularization protocol enabled us to obtain a completely acellular renal scaffold while maintaining the extracellular matrix structure and composition in terms of collagen IV, laminin, and fibronectin. NS cells, cultured on decellularized renal scaffolds with basal medium, differentiated into proximal and distal tubules as well as endothelium, as highlighted by histology and by the specific expression of epithelial cytokeratin 8.18, proximal tubular CD10, distal tubular cytokeratin 7, and endothelial von Willebrand factor markers. Endothelial medium promoted the differentiation toward the endothelium, whereas epithelial medium promoted the differentiation toward the epithelium. NS cells seem to be a good tool for scaffold repopulation, paving the way for experimental investigations focused on whole-kidney reconstruction.

Towards a Bioengineered Kidney: Recellularization Strategies for Decellularized Native Kidney Scaffolds. Int J Artif Organs 2017; 40:150-158.

Abstract
Patients with end-stage renal disease often undergo dialysis as a partial substitute for kidney function while waiting for their only treatment option: a kidney transplant. Several research directions emerged for alternatives in support of the ever-growing numbers of patients. Recent years brought big steps forward in the field, with researchers questioning and improving the current dialysis devices as well as moving towards the design of a bioengineered kidney. Whole-organ engineering is also being explored as a possibility, making use of animal or human kidney scaffolds for engineering a transplantable organ. While this is not a new strategy, having been applied so far for thin tissues, it is a novel approach for complex organs such as the kidneys. Kidneys can be decellularized and the remaining scaffold consisting of an extracellular matrix can be repopulated with (autologous) cells, aiming at growing ex vivo a fully transplantable organ. In a broader view, such organs might also be used for a better understanding of fundamental biological concepts and disease mechanisms, drug screening and toxicological investigations, opening new pathways in the treatment of kidney disease. Decellularization of whole organs has been widely explored and described; therefore, this manuscript only briefly reviews some important considerations with an emphasis on scaffold decontamination, but focuses further on recellularization strategies. Critical aspects, including cell types and sources that can be used for recellularization, seeding strategies and possible applications beyond renal replacement are discussed.

Abstract
The rising number of patients needing renal replacement therapy, alongside the significant clinical and economic limitations of current therapies, creates an imperative need for new strategies to treat kidney diseases. Kidney bioengineering through the production of acellular scaffolds and recellularization with stem cells is one potential strategy. While protocols for obtaining organ scaffolds have been developed successfully, scaffold recellularization is more challenging. We evaluated the potential of in vivo and in vitro kidney scaffold recellularization procedures. Our results show that acellular scaffolds implanted in rats cannot be repopulated with host cells, and in vitro recellularization is necessary. However, we obtained very limited and inconsistent cell seeding when using different infusion protocols, regardless of injection site. We also obtained experimental and theoretical data indicating that uniform cell delivery into the kidney scaffolds cannot be obtained using these infusion protocols, due to the permeability of the extracellular matrix of the scaffold. Our results highlight the major physical barriers that limit in vitro recellularization of acellular kidney scaffolds and the obstacles that must be investigated to effectively advance this strategy for regenerative medicine.

Abstract
Decellularized porcine kidneys were recellularized with renal epithelial cells by three methods: perfusion through the vasculature under high pressure, perfusion through the ureter under high pressure, or perfusion through the ureter under moderate vacuum. Histology, scanning electron microscopy, confocal microscopy, and magnetic resonance imaging were used to assess vasculature preservation and the distribution of cells throughout the kidneys. Cells were detected in the magnetic resonance imaging by labeling them with iron oxide. Perfusion of cells through the ureter under moderate vacuum (40 mmHg) produced the most uniform distribution of cells throughout the kidneys.

Abstract
Organoids are self-organizing, multicellular structures that contain multiple cell types, represent organ structure and function, and can be used to model organ development, maintenance and repair ex vivo. Organoids, derived from embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs) or adult stem cells, are cultured in extracellular matrix (ECM). Organoid cultures have been developed for multiple organs and for the kidney, pluripotent stem cell (PSCs) derived organoid technology has rapidly developed in the last three years. Here, we review available PSC differentiation protocols, focusing on the pluripotent stem cells to initiate the organoid culture, as well as on growth factors and ECM used to regulate differentiation and expansion. In addition, we will discuss the read out strategies to evaluate organoid phenotype and function. Finally, we will indicate how the choice of both culture parameters and read out strategy should be tailored to specific applications of the organoid culture.

Abstract
Chronic kidney diseases affect thousands of people worldwide. Although hemodialysis alleviates the situation by filtering the patient's blood, it does not replace other kidney functions such as hormone release or homeostasis regulation. Consequently, orthotopic transplantation of donor organs is the ultimate treatment for patients suffering from end-stage renal failure. Unfortunately, the number of patients on the waiting list far exceeds the number of donors. In addition, recipients must remain on immunosuppressive medications for the remainder of their lives, which increases the risk of morbidity due to their weakened immune system. Despite recent advancements in whole organ transplantation, 40% of recipients will face rejection of implanted organs with a life expectancy of only 10 years. Bioengineered patient-specific kidneys could be an inexhaustible source of healthy kidneys without the risk of immune rejection. The purpose of this article is to review the pros and cons of several bioengineering strategies used in recent years and their unresolved issues. These strategies include repopulation of natural scaffolds with a patient's cells, de-novo generation of kidneys using patient-induced pluripotent stem cells combined with stepwise differentiation, and the creation of a patient's kidney in the embryos of other mammalian species.
