Abstract
The respiratory system, which includes the trachea, airways, and distal alveoli, is a complex multi-cellular organ that intimately links with the cardiovascular system to accomplish gas exchange. In this review and as members of the NIH/NHLBI-supported Progenitor Cell Translational Consortium, we discuss key aspects of lung repair and regeneration. We focus on the cellular compositions within functional niches, cell-cell signaling in homeostatic health, the responses to injury, and new methods to study lung repair and regeneration. We also provide future directions for an improved understanding of the cell biology of the respiratory system, as well as new therapeutic avenues.

Post-transplant outcomes of standard and extended criteria donation after circulatory death donor lungs categorized by donation after brain death lung criteria. Eur J Cardiothorac Surg 2021; 60:590-597. [PMID: 33693567 DOI: 10.1093/ejcts/ezab121] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 02/02/2021] [Accepted: 02/08/2021] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES Most transplant centres use donation after brain death (DBD) criteria to assess the quality of controlled donation after circulatory death (cDCD) lungs. However, research on the relationship between DBD extended criteria and cDCD lung transplantation outcomes is limited. We investigated the outcomes of using DBD extended criteria donor organs in cDCD lung transplantation, compared to the standard criteria cDCD lung transplantation. METHODS A retrospective chart review of consecutive cDCD lung referrals to Hospital Universitario Puerta de Hierro-Majadahonda from June 2013 to December 2019 was undertaken. Donors were divided into standard and extended criteria groups. Early outcomes after lung transplant were compared between these groups using the Kaplan-Meier method and log-rank test. RESULTS Thirty out of 91 cDCD donor lung offers were accepted for transplantation, of which 11 were from standard criteria donors and 19 were extended criteria donors. The baseline characteristics of the 2 recipient groups were similar. There were no differences in the rates of grade 3 primary graft dysfunction at 72 h after lung transplantation (21% vs 18%), duration of mechanical ventilation (48 h vs 36 h), total intensive care unit stay (10 days vs 7 days) and 1-year survival (89% vs 90%). CONCLUSIONS Carefully selecting cDCD lungs from outside the standard acceptability criteria may expand the existing donor pool with no detrimental effects on lung transplantation outcomes.

Abstract
As neurologists earn their living with the preservation and restoration of brain function, they are also well-positioned to address the science behind the transition from life to death. This essay in pictures highlights areas of neurological expertise needed for brain death determination; shows pitfalls to avoid during the clinical examination and interpretation of confirmatory laboratory tests in brain death protocols; illustrates the great variability of brain death legislations around the world; discusses arguments for the implementation of donation after circulatory death (DCD); points to unresolved questions related to DCD and the time between cardiac standstill and organ procurement (“hands-off period”); provides an overview of the epidemiology and semiology of near-death experiences, including their importance for religion, literature, and the visual arts; suggests biological mechanisms for near-death experiences such as dysfunction of temporoparietal cortex, N-methyl-D-aspartate receptor antagonism, migraine aura, and rapid eye movement sleep; hypothesizes that thanatosis (aka. death-feigning, a common behavioral trait in the animal kingdom) represents the evolutionary origin of near-death experiences; and speculates about the future implications of recent attempts of brain resuscitation in an animal model. The aim is to provide the reader with a thorough understanding that the boundaries within the neurology of death and the dying brain are being pushed just like everywhere else in the clinical neurosciences.

Abstract
BACKGROUND It is poorly understood how public perception of the difference between brain death and circulatory death may influence attitudes towards organ donation. We investigated the public opinion on brain death versus circulatory death and documented inconsistencies in the legislations of countries with different cultural and socioeconomic backgrounds. METHODS Using a crowdsourcing approach, we randomized 1072 participants from 30 countries to a case report of organ donation after brain death or to one following circulatory death. Further, we sampled guidelines from 24 countries and 5 continents. RESULTS Of all participants, 73% stated they would be willing to donate all organs, while 16% would want to donate some of their organs. To increase the rate of donations, 47% would agree with organ donation without family consent as the default. Exposure to "brain death" was not associated with a lesser likelihood of participants agreeing with organ donation (82.1%) compared to "circulatory death" (81.9%; relative risk 1.02, 95% CI 0.99 to 1.03; p = .11). However, participants exposed to "circulatory death" were more certain that the patient was truly dead (87.9% ± 19.7%) than participants exposed to "brain death" (84.1% ± 22.7%; Cohen's d 0.18; p = 0:004). Sampling of guidelines revealed large differences between countries regarding procedures required to confirm brain death and circulatory death, respectively. CONCLUSIONS Implementation of organ donation after circulatory death is unlikely to negatively influence the willingness to donate organs, but legislation is still brain death-based in most countries. The time seems ripe to increase the rate of circulatory death-based organ donation.

Abstract
BACKGROUND Severe ischemia-reperfusion injury (SIRI) seems to be the key factor that can significantly affect the function of both native kidneys and renal allografts. Therefore, the development of a successful strategy is of a paramount importance in both basic and clinical research. METHODS To determine the effects of SIRI on the native kidney function, a murine model was planned as follows: group 1 (n = 6) mice underwent to nephrectomy plus ischemia-reperfusion injury for 30 minutes; group 2 (n = 6) mice underwent to nephrectomy without ischemia-reperfusion injury and thus served as sham controls for SIRI. The results of serum creatinine (SCr) were analyzed using Mann-Whitney U tests to calculate the significance between mean values. Survival between groups was measured by Kaplan-Meier test. RESULTS To reliably achieve an elevation of SCr levels animals were exposed to a SIRI. The values of SCr increased from 0.35 (SD, 0.09) mg/dL to about 2-fold within 2 days and 3-fold within the following 5 days. Under these given conditions the mice displayed signs and histologic findings of severe kidney damage. The survival rate was about 83% of the animals within a week, and they showed no capacity of complete spontaneous self-regeneration. CONCLUSIONS In this study, we aim to establish a murine model with extensive structural kidney damage and significant elevation of SCr levels, which could be used in basic and translational research of transplantation and regenerative therapies.

Abstract
PURPOSE To investigate the long non-coding RNAs (lncRNAs) profile on renal ischemia reperfusion in a mouse model. METHODS Microarray analysis was used to study the expression of misregulated lncRNA in a mouse model of renal ischemia reperfusion(I/R) with long ischemia time. Quantitative real-time PCR (qPCR) was used to verify the expression of selected lncRNAs and mRNAs.The potential functions of the lncRNA was analyzed by bioinformatics tools and databases. RESULTS Kidney function was impaired in I/R group compared to the normal group. Analysis showed that a total of 2267 lncRNAs and 2341 messenger RNAs (mRNAs) were significantly expressed in I/R group (≥2.0-fold, p < 0.05).The qPCR result showed that lncRNAs and mRNAs expression were consistent with the microarray analysis. The co-expression network profile analysis based on five validated lncRNAs and 203 interacted mRNAs showed it existed a total of 208 nodes and 333 connections. The GO and KEEG pathway analysis results showed that multiple lncRNAs are involved the mechanism of I/R. CONCLUSION Multiple lncRNAs are involved in the mechanism of I/R.These analysis results will help us to further understand the mechanism of I/R and promote the new methods targeted at lncRNA to improve I/R injury.

Abstract
BACKGROUND As the number of patients with end-stage lung disease continues to rise, there is a growing need to increase the limited number of lungs available for transplantation. Unfortunately, attempts at engineering functional lung de novo have been unsuccessful, and artificial mechanical devices have limited utility as a bridge to transplant. This difficulty is largely due to the size and inherent complexity of the lung; however, recent advances in cell-based therapeutics offer a unique opportunity to enhance traditional tissue-engineering approaches with targeted site- and cell-specific strategies. METHODS Human lungs considered unsuitable for transplantation were procured and supported using novel cannulation techniques and modified ex-vivo lung perfusion. Targeted lung regions were treated using intratracheal delivery of decellularization solution. Labeled mesenchymal stem cells or airway epithelial cells were then delivered into the lung and incubated for up to 6 hours. RESULTS Tissue samples were collected at regular time intervals and detailed histologic and immunohistochemical analyses were performed to evaluate the effectiveness of native cell removal and exogenous cell replacement. Regional decellularization resulted in the removal of airway epithelium with preservation of vascular endothelium and extracellular matrix proteins. After incubation, delivered cells were retained in the lung and showed homogeneous topographic distribution and flattened cellular morphology. CONCLUSIONS Our findings suggest that targeted cell replacement in extracorporeal organs is feasible and may ultimately lead to chimeric organs suitable for transplantation or the development of in-situ interventions to treat or reverse disease, ultimately negating the need for transplantation.

Abstract
Liver transplantation (LT) has become the treatment of choice for a wide range of liver diseases in both adult and pediatric patients. Until recently, the largest proportion of LT in adults, were performed in patients with hepatitis C (HCV) related cirrhosis. The recent availability of safe and effective direct antiviral agents to cure HCV infection in almost all patients whatever the HCV genotype and severity of liver disease, will reduce the need for LT in this category of recipients. Thus, it is presumed that in the next 1 to 2 decades HCV related liver disease will diminish substantially, whereas non-alcoholic steato-hepatitis (NASH) will correspondingly escalate as an indication for LT. The greatest challenges facing LT remain the limited supply of donor organs, and the need for chronic immunosuppression, which represent the true obstacles to the greater application and durable success of the LT procedure. This review aimed to highlight, in different sections, the main open issues and future developments in LT. These will be focused to explore current and future strategies to maximize the use of limited organs, to offer an update on potential new approaches to immunosuppression and to imagine new indications for LT when the number of patients awaiting transplants for HCV related liver disease is reduced.

Abstract
Repair of injured lungs represents a longstanding therapeutic challenge. We recently demonstrated that human and mouse embryonic lung tissue from the canalicular stage of development are enriched with lung progenitors, and that a single cell suspension of canalicular lungs can be used for transplantation, provided that lung progenitor niches in the recipient mice are vacated by strategies similar to those used in bone marrow transplantation. Considering the ethical limitations associated with the use of fetal cells, we investigated here whether adult lungs could offer an alternative source of lung progenitors for transplantation. We show that intravenous infusion of a single cell suspension of adult mouse lungs from GFP+ donors, following conditioning of recipient mice with naphthalene and subsequent sublethal irradiation, led to marked colonization of the recipient lungs, at 6-8 weeks post-transplant, with donor derived structures including epithelial, endothelial, and mesenchymal cells. Epithelial cells within these donor-derived colonies expressed markers of functionally distinct lung cell types, and lung function, which is significantly compromised in mice treated with naphthalene and radiation, was found to be corrected following transplantation. Dose response analysis suggests that the frequency of patch forming cells in adult lungs was about threefold lower compared to that found in E16 fetal lungs. However, as adult lungs are much larger, the total number of patch forming cells that can be collected from this source is significantly greater. Our study provides proof of concept for lung regeneration by adult lung cells after preconditioning to vacate the pulmonary niche. Stem Cells Translational Medicine 2018;7:68-77.
