Organ xenotransplantation acceptance in veterinary students: A multicentric opinion study in Spain. Xenotransplantation 2023; 30:e12823. [PMID: 37695105 DOI: 10.1111/xen.12823] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/27/2023] [Accepted: 08/29/2023] [Indexed: 09/12/2023]
Abstract
BACKGROUND The shortage of available transplant organs has made it necessary to search for alternatives, one of which is xenotransplantation. However, the use of animal organs could face rejection from society and the personnel involved in its implementation. OBJECTIVES (a) to analyze the attitudes of Veterinary Degree students in six Spanish Universities towards xenotransplantation; and (b) to determine the factors that affect its acceptance. METHODS Of the 2815 students surveyed in the degree program, 2683 valid surveys were obtained. Attitudes towards organ xenotransplantation were evaluated using a validated questionnaire of organ donation. RESULTS If xenotransplantation was confirmed as a clinical reality, 93% (n = 2493) of those surveyed would accept a xenotransplanted organ, whilst 7% would not. If the results of xenotransplantation were worse than those obtained with human donors and it entailed more risk, 12% (n = 318) would be in favor. 56% (n = 1497) of the students would accept a xenotransplantation provisionally pending the arrival of a human organ. Attitudes towards xenotransplantation were affected by the academic year in which a student was studying, with more favorable attitudes among students in the last year (88% in first year vs. 95% in fifth year; p < .001). More favorable attitudes are also observed depending on the attitude they have towards organ transplantation, with those students being more in favor of donating their organs when they die (94% vs. 88%; p < .001). CONCLUSION Veterinary students would have a very favorable attitude toward xenotransplantation if these animal organs functioned as well as human organs. Therefore, these students could play an important role in the future promotion of this technique.

Abstract
In utero hematopoietic cell transplantation (IUHCT) is considered a potentially efficient therapeutic approach with relatively few side effects, compared to adult hematopoietic cell transplantation, for various hematological genetic disorders. The principle of IUHCT has been extensively studied in rodent models and in some large animals with close evolutionary similarities to human beings. However, IUHCT has only been used to rebuild human T cell immunity in certain patients with inherent immunodeficiencies. This review will first summarize the animal models utilized for IUHCT investigations and describe the associated outcomes. Recent advances and potential barriers for successful IUHCT are discussed, followed by possible strategies to overcome these barriers experimentally. Lastly, we will outline the progress made towards utilizing IUHCT to treat inherent disorders for patients, list out associated limitations and propose feasible means to promote the efficacy of IUHCT clinically.

Abstract
Information on the biodistribution (BD) of cell therapy products (CTPs) is essential for prediction and assessment of their efficacy and toxicity profiles in non-clinical and clinical studies. To conduct BD studies, it is necessary to understand regulatory requirements, implementation status, and analytical methods. This review aimed at surveying international and Japanese trends concerning the BD study for CTPs and the following subjects were investigated, which were considered particularly important: 1) comparison of guidelines to understand the regulatory status of BD studies in a global setting; 2) case studies of the BD study using databases to understand its current status in cell therapy; 3) case studies on quantitative polymerase chain reaction (qPCR) used primarily in non-clinical BD studies for CTPs; and 4) survey of imaging methods used for non-clinical and clinical BD studies. The results in this review will be a useful resource for implementing BD studies.

Abstract
Background Animals can play an important role in preparing tissues for human through the development of xenotransplantation protocols. The most common problem with liver transplantation like any other organ transplantation is organ supply shortage. Objective To evaluate the in utero xenotransplantation of mouse bone marrow-derived stromal/stem cells (BMSCs) to the liver of rat fetus to produce mouse liver tissue. Materials and Methods BMSCs were isolated and confirmed from enhanced green fluorescent protein (eGFP)-genetic labeled mice. Using a microinjection protocol, mice BMSCs were injected into the liver of rat fetuses in utero on day 14 of pregnancy. After birth, livers were collected and the presence of mice eGFP-positive cells in rat livers was evaluated through polymerase chain reaction. Results The eGFP mRNA was detected in the liver of injected infant rats. BMSCs of adult mice were capable to remain functional probably as hepatocyte-like cells in liver of infant rats after in utero xenotransplantation. Conclusion BMSCs have the potential for intrauterine xenotransplantation for the treatment of liver dysfunction before birth. This method can also be used for xenoproduction of liver tissue for transplantation.

Abstract
INTRODUCTION Recent immunological and transgenic advances are a promising alternative using limited materials of human origin for transplantation. However, it is essential to achieve social acceptance of this therapy. OBJECTIVE To analyze the attitude of nursing students from Spanish universities toward organ xenotransplantation (XTx) and to determine the factors affecting their attitude. MATERIALS AND METHODS Type of study: A sociological, multicentre, and observational study. STUDY POPULATION Nursing students enrolled in Spain (n = 28,000). SAMPLE SIZE A sample of 10 566 students estimating a proportion of 76% (99% confidence and precision of ±1%), stratified by geographical area and year of study. Instrument of measurement: A validated questionnaire (PCID-XenoTx-RIOS) was handed out to every student in a compulsory session. This survey was self-administered and self-completed voluntarily and anonymously by each student in a period of 5-10 min. STATISTICAL ANALYSIS descriptive analysis, Student's t test, the chi-square test, and a logistic regression analysis. RESULTS A completion rate: 84% (n = 8913) was obtained. If the results of XTx were as good as in human donation, 74% (n = 6564) would be in favor and 22% (n = 1946) would have doubts. The following variables affected this attitude: age (P < 0.001); sex (P < 0.001); geographical location (P < 0.001); academic year of study (P < 0.001); attitude toward organ donation (P < 0.001); belief in the possibility of needing a transplant (P < 0.001); discussion of transplantation with one's family (P < 0.001) and friends (P < 0.001); and the opinion of one's partner (P < 0.001). The following variables persisted in the multivariate analysis: being a male (OR = 1.436; P < 0.001); geographical location (OR = 1.937; P < 0.001); an attitude in favor of donation (OR = 1.519; P < 0.001); belief in the possibility of needing a transplant (OR = 1.497; P = 0.036); and having spoken about the issue with family (OR = 1.351; P < 0.001) or friends (OR = 1.240; P = 0.001). CONCLUSIONS The attitude of nursing students toward organ XTx is favorable and is associated with factors of general knowledge about organ donation and transplantation and social interaction.

Abstract
Swine are a commonly used animal model for biomedical research. One research application of swine models is the in utero injection of human or pig cells into the fetal liver (FL) or intraperitoneal space. In utero injections can be accomplished through laparotomy procedures in pregnant swine. In this study, we aimed to establish comprehensive laparotomy protocols for ultrasound-guided injections into fetuses. Two pregnant gilts, with a total of 16 fetuses, underwent laparotomy at 41 and 42 d of gestation. During surgery, we attempted to inject half of the fetuses in the FL or intraperitoneal space with saline and titanium wire for radiographic imaging after birth. After the laparotomy and fetal injections, both gilts maintained pregnancy throughout gestation and initiated labor at full term. Of the 16 fetuses present at the time of laparotomy, 12 were liveborn, 2 were stillborn, and the remaining 2 were mummies. A total of 7 fetuses from the 2 litters were known to have been injected with a wire during the surgery. After farrowing, piglets were radiographed, and 6 piglets were identified to have wire within the abdominal space. Livers were dissected, and additional radiographs were obtained. It was determined that one piglet had wire within the liver, whereas the other 5 had wire within the intraperitoneal space. Overall, we describe in-depth laparotomy surgery protocols, ultrasound-guided injection of saline and titanium wire into the FL or intraperitoneal space, postoperative monitoring protocols, and information on radiographic detection of titanium wire after piglet birth. These protocols can be followed by other research groups intending to inject cells of interest into either the intraperitoneal space or FL of fetal piglets.

Abstract
This work was undertaken to evaluate whether a real-time quantitative polymerase chain reaction (qPCR) is as an adequate method for detection and quantification of human-specific DNA elements (Alu gene) in tissues and blood samples of pigs in which human stem cells were engrafted. Real-time qPCR quantification was performed with the use of previously described primers. The human DNA was mixed with different quantities of porcine DNA. The primer concentration and specificity, the qPCR efficiency, the quantification variations due to different porcine DNA concentrations, and the dissociation curve produced by the assay were evaluated. The qPCR proved to be specific, robust, with a reproducible and specific bimodal melting curve. High porcine DNA concentration produced subquantification, especially with low human DNA quantity. However, the assay proved to be useful for the detection of chimeric piglets produced by human cells injected in utero, because the effect caused by the porcine DNA interference was corrected in quantification of human DNA from piglets.

Abstract
BACKGROUND The objective of this study was to investigate the humoral immune response to xenogeneic antigens administered during the fetal state utilizing a baboon-to-pig model. METHODS Nine fetuses from an alpha-1,3-galactosyltransferase gene knockout (GalT-KO) MGH-miniature swine sow underwent transuterine ultrasound-guided intraportal injection of T-cell depleted baboon bone marrow (B-BM) at mid-gestation. Two juvenile GalT-KO swine undergoing direct B-BM intraportal injection were used as controls. RESULTS Postnatal humoral tolerance was induced in the long-term surviving piglets as demonstrated by the absence of any antibody response to baboon donor cells. In addition, a second intraportal B-BM administration at 2.5 months post-birth led to no antibody formation despite re-exposure to xenogeneic antigens. This B-cell unresponsiveness was abrogated only when the animal was exposed subcutaneously to third-party xenogeneic and allogeneic antigens, suggesting that the previously achieved humoral non-responsiveness was donor specific. In comparison, the two juvenile GalT-KO control swine demonstrated increasing anti-baboon IgM and IgG levels following intraportal injection. CONCLUSIONS In summary, xenogeneic B-cell tolerance was induced through in utero intraportal exposure to donor cells and this tolerance persisted following postnatal rechallenge with donor B-BM, but was lost on exposure to third-party antigen, possibly as a result of cross-reactive antibody formation.

Abstract
Many tissue-engineering approaches for repair and regeneration involve transplants between species. Yet a challenge is distinguishing donor versus host effects on gene expression. This study provides a simple molecular strategy to quantify species-specific contributions in chimeras and xenografts. Species-specific primers for reverse transcription quantitative real-time PCR (RT-qPCR) were designed by identifying silent mutations in quail, duck, chicken, mouse and human ribosomal protein L19 (RPL19). cDNA from different pairs of species was mixed in a dilution series and species-specific RPL19 primers were used to generate standard curves. Then quail cells were transplanted into transgenic-GFP chick and resulting chimeras were analyzed with species-specific primers. Fluorescence-activated cell sorting (FACS) confirmed that donor- and host-specific levels of RPL19 expression represent actual proportions of cells. To apply the RPL19 strategy, we measured Runx2 expression in quail-duck chimeras. Elevated Runx2 levels correlated with higher percentages of donor cells. Finally, RPL19 primers also discriminated mouse from human and chick. Thus, this strategy enables chimeras and/or xenografts to be screened rapidly at the molecular level.
