Abstract
The most common cause of acquired thyroid dysfunction is autoimmune thyroid disease, which is an organ-specific autoimmune disease with two presentation phenotypes: hyperthyroidism (Graves-Basedow disease) and hypothyroidism (Hashimoto's thyroiditis). Hashimoto's thyroiditis is distinguished by the presence of autoantibodies against thyroid peroxidase and thyroglobulin. Meanwhile, autoantibodies against the TSH receptor have been found in Graves-Basedow disease. Numerous susceptibility genes, as well as epigenetic and environmental factors, contribute to the pathogenesis of both diseases. This review summarizes the most common genetic, epigenetic, and environmental mechanisms involved in autoimmune thyroid disease.

Abstract
There is a bidirectional transplacental cell trafficking between mother and fetus during pregnancy in placental mammals. The presence and persistence of fetal cells in maternal tissues are known as fetal microchimerism (FMc). FMc has high multilineage potential with a great ability to differentiate and functionally integrate into maternal tissue. FMc has been found in various maternal tissues in animal models and humans. Its permanence in the maternal body up to decades after delivery suggests it might play an essential role in maternal pathophysiology. Studying the presence, localization, and characteristics of FMc in maternal tissues is key to understanding its impact on the woman's body. Here we comprehensively review the existence of FMc in different species and organs and tissues, aiming to better characterize their possible role in human health and disease. We also highlight several methodological considerations that would optimize the detection, quantification, and functional determination of FMc.

Abstract
We encountered a 30-year-old woman who developed dermatomyositis during pregnancy and was positive for anti-Mi-2 antibodies. She was successfully treated with prednisolone and tacrolimus and delivered a healthy child. We reviewed the cases of idiopathic inflammatory myositis (IIM) that developed during pregnancy that were published after the year 2000 to elucidate the profile of myositis-specific antibodies (MSAs) in them and to evaluate their obstetric outcomes. In cases with IIM that developed during pregnancy, anti-Mi-2, anti-TIF1-g, anti-Jo-1, and anti-EJ antibodies was detected in one case each. The obstetric outcomes of the IIM-complicated pregnancies were poor, especially when complicated with active maternal myositis. Further studies focusing on the possible causal relationships between MSAs and cases with IIM that developed during pregnancy are needed. For better obstetric outcomes, appropriate suppression of the maternal disease activity using immunosuppressants and vigilance regarding the patient's requirement of Caesarean section is important.

Abstract
Prenatal diagnosis plays a crucial role in clinical genetics. Non-invasive prenatal diagnosis using fetal cells circulating in maternal peripheral blood has become the goal of prenatal diagnosis, to obtain complete fetal genetic information and avoid risks to mother and fetus. The development of high-efficiency separation technologies is necessary to obtain the scarce fetal cells from the maternal circulation. Over the years, multiple approaches have been applied, including choice of the ideal cell targets, different cell recovering technologies, and refined cell isolation yield procedures. In order to provide a useful tool and to give insights about limitations and advantages of the technologies available today, we review the genetic research on the creation and validation of non-invasive prenatal diagnostic testing protocols based on the rare and labile circulating fetal cells during pregnancy.

Abstract
Maternal-fetal immune-tolerance occurs throughout the whole gestational trimester, thus a mother can accept a genetically distinct fetus without immunological aggressive behavior. HLA-G, one of the non-classical HLA class I molecules, is restricted-expression at extravillous trophoblast. It can concordantly interact with various kinds of receptors mounted on maternally immune cells residing in the uterus (e.g. CD4+ T cells, CD8+ T cells, natural killer cells, macrophages, and dendritic cells) for maintaining immune homeostasis of the maternal-fetus interface. HLA-G is widely regarded as the pivotal protective factor for successful pregnancies. In the past 20 years, researches associated with HLA-G have been continually published. Indeed, HLA-G plays a mysterious role in the mechanism of maternal-fetal immune-tolerance. It can also be ectopically expressed on tumor cells, infected sites and other pathologic microenvironments to confer a significant local tolerance. Understanding the characteristics of HLA-G in immunologic tolerance is not only beneficial for pathological pregnancy, but also helpful to the therapy of other immune-related diseases, such as organ transplant rejection, tumor migration, and autoimmune disease. In this review, we describe the biological properties of HLA-G, then summarize our understanding of the mechanisms of fetomaternal immunologic tolerance and the difference from transplant tolerance. Furthermore, we will discuss how HLA-G contributes to the tolerogenic microenvironment during pregnancy. Finally, we hope to find some new aspects of HLA-G in fundamental research or clinical application for the future.

Abstract
During pregnancy several types of fetal cells and fetal stem cells, including pregnancy-associated progenitor cells (PAPCs), traffic into the maternal circulation. Whereas they also migrate to various maternal organs and adopt the phenotype of the target tissues to contribute to regenerative processes, fetal cells also play a role in the pathogenesis of maternal diseases. In addition, cell-free fetal DNA (cffDNA) is detectable in the plasma of pregnant women. Together they constitute the well-known phenomenon of fetomaternal microchimerism, which inspired the concept of non-invasive prenatal testing (NIPT) using maternal blood. An in-depth knowledge concerning the origins of these fetal cells and cffDNA allows a more comprehensive understanding of the biological relevance of fetomaternal microchimerism and has implications for the ongoing expansion of resultant clinical applications.

J Clin Med 2021; 10:jcm10122613.

Abstract
Known etiologic factors can only be found in about 50% of patients with recurrent pregnancy loss (RPL). We hypothesized that male microchimerism is a risk factor for RPL and aimed to explore whether information on family tree and reproductive history, obtained from 383 patients with unexplained RPL, was supportive of this hypothesis. The male:female sex ratio of older siblings was 1.49 (97:65) in all RPL patients and 1.79 (52:29) in secondary RPL (sRPL) patients, which differed significantly from the expected 1.04 ratio (p = 0.027 and p = 0.019, respectively). In contrast, the sex ratio of younger siblings was close to the expected ratio. Sex ratio of the firstborn child before sRPL was 1.51 (p = 0.026). When combined, 79.1% of sRPL patients had at least one older brother, a firstborn boy, or both. This differed significantly from what we expected based on the distribution of younger siblings and a general 1.04 sex ratio of newborns (p = 0.040). We speculate whether (s)RPL patients possibly acquired male microchimerism from older brother(s) and/or previous birth of boy(s) by transplacental cell trafficking. This could potentially have a detrimental impact on their immune system, causing a harmful response against the fetus or trophoblast, resulting in RPL.

Abstract
Feto-maternal immune tolerance is established during pregnancy; however, its mechanism and maintenance remain underexplored. Here, we investigated whether mesenchymal stem/stromal cells (MSCs) as non-inherited maternal antigens (NIMAs) transferred by maternal microchimerism could induce immune tolerance. We showed that MSCs had a potential equivalent to hematopoietic stem and progenitor cells (HSPCs) to induce immune tolerance and that MSCs were essential to induce tolerance to MSC-specific antigens. Furthermore, we demonstrated that MSCs as NIMAs transferred by maternal microchimerism could induce robust immune tolerance that can be further enhanced using a drug. Our data shed light on induction of immune tolerance and serve as a foundation to develop new therapies using maternally derived cells for autoimmune or genetic diseases.

Abstract
Brazilian-born British biologist Dr. Peter Medawar played an integral role in developing the concepts of immunologic rejection and tolerance, which led to him receiving the Nobel Prize "for the discovery of acquired immunologic tolerance" and eventually made organ transplantation a reality. However, at the time of his early work in tolerance, a paradox to his theories was brought to his attention; how was pregnancy possible? Pregnancy resembles organ transplantation in that the fetus, possessing paternal antigens, is a semi-allogeneic graft that can survive without immunosuppression for 9 months. To answer this question, Medawar proposed three hypotheses of how a mother supports her fetus in utero, now known as "Medawar's Paradox." The mechanisms that govern fetomaternal tolerance are still incompletely understood but may provide critical insight into how to achieve immune tolerance in organ transplantation. Here, we review current understanding of the immune factors responsible for fetomaternal tolerance during pregnancy and discuss the potential implications for advances in transplantation science.

Abstract
Despite the advances in medicine, about 4 million children under the age of 6 months die annually around the world due to infection, which is 450 deaths per hour (UNISEF, 2009). The degree of development of the immune system of children born in time is determined by many factors, including the immunogenetic similarity or difference of mother and fetus organisms, which, in turn, is due to the genotypes of mating pairs, as well as the selection of surrogate mothers duringin vitrofertilization. From our review of the literature, it follows that immunogenetic interactions of mother and fetus organisms, which occur at all stages of pre- and postnatal development, have a signifcant effect on the resistance of offspring to infections and allergens. Before implantation, the mother’s immune responses are formed under the influence of semen fluid antigens, leukocytes and cytokines, as well as under the influence of the genes of the major histocompatibility complex, which are expressed in embryos at the stage of two cells. After implantation, transplacental transfer of immunoglobulins and immunocompetent cells becomes of immunomodulating importance. It is important to emphasize that, although substances with a high molecular weight usually do not pass through the placenta, this rule does not apply to immunoglobulin G (IgG), which, with a molecular weight of about 160 kDa, overcomes the transplacental barrier due to binding to the fetal Fc receptor. The level of IgG in newborns usually correlates with the level of maternal antibodies. During the period of natural feeding, the immune protection of newborns is provided by the mechanisms of innate immunity and the factors of humoral immunity of mothers. It has been shown that immunoglobulins from the milk of many animal species are transferred through the neonatal intestinal epithelium to the blood. Since breast milk contains large amounts of various immunoactive components, including proteins, cytokines, hormones, immunoglobulins, exosomes containing micro-RNA, and viable immune cells, the immunomodulating effects of breast milk persist even after elimination of maternal immunoglobulins from the blood of the offspring, up to maturation. Analysis of a large body of experimental data shows that the study of mechanisms of “motherfetus” and “mother-newborn” interactions are the basis of a knowledge base needed to fnd means of life-long directed modulation of the descendants’ immune status.

Abstract
Microchimerism is the presence of cells from one individual in another genetically distinct individual. Pregnancy is the main cause of natural microchimerism through transplacental bi-directional cell trafficking between mother and fetus. In addition to a variety of cell-free substances, it is now well-recognized that some cells are also exchanged in pregnancy. Furthermore, it is now known that microchimerism persists decades later both in mother and in her progeny. The consequences of pregnancy-related microchimerism are under active investigation. However, many authors have suggested a close relationship linking fetal microchimerism and the development of autoimmune diseases. Fetal microchimerism is emerging as a potential contributing factor in certain diseases, including cancer. Parallel studies in animal and human pregnancy suggest that microchimeric fetal cells play a role in wound healing. Role of these microchimeric cells in human health and disease is discussed here.

Abstract
The presence of microchimeric cells is known for >100 years and well documented since decades. Earlier, microchimeric cells were mainly used for cell-based non-invasive prenatal diagnostics during early pregnancy. Microchimeric cells are also present beyond delivery and are associated to various autoimmune diseases, tissue repair, cancer and immune tolerance. All these findings were based on low complexity studies and occasionally accompanied by artefacts not allowing the biological functions of microchimerism to be determined. However, with the recent developments in single-cell analysis, new means to identify and characterize microchimeric cells are available. Cell labelling techniques in combination with single-cell analysis provide a new toolbox to decipher the biology of microchimeric cells at molecular and cellular level. In this review, we discuss how recent developments in single-cell analysis can be applied to determine the role and function of microchimeric cells.

Ichinohe T. Long-term feto-maternal microchimerism revisited: Microchimerism and tolerance in hematopoietic stem cell transplantation. CHIMERISM 2017; 1:39-43.

Abstract
Bidirectional fetal-maternal cell traffic during pregnancy gives rise to stable persistence of minute amounts of allogeneic cells both in the mother and in her offspring, a phenomenon called long-term fetal or maternal microchimerism. Over the past decade, increasing attention has been devoted to elucidating the biological relevance of such reciprocal microchimerism, unveiling its conflicting roles in either immune sensitization or tolerance induction against fetal or maternal alloantigens. Recent studies in mice and humans have highlighted the significance of fetal-maternal microchimerism in the induction and maintenance of CD4(+)CD25(+) and CD8(+) T regulatory cells that counterbalance the immune responses to fetal or maternal antigens mediated by T effector cells. Consistent with these observations, T-cell-replete hematopoietic stem cell transplantation between mutually microchimeric mothers and their HLA-haploidentical offspring has been shown to be feasible, although the degree of microchimerism-associated tolerance appears to substantially differ among the cases. Since in vitro or trans-vivo assays to detect antigen-specific tolerance in the context of the T regulator versus T effector balance are now available, future clinical studies incorporating these tests into the criteria for donor selection are warranted to more precisely define the relevance of fetal-maternal microchimerism in allotolerance and immune homeostasis after hematopoietic stem cell transplantation.

Abstract
BACKGROUND A long sought goal in medical genetics has been the replacement of invasive procedures for the detection of chromosomal aneuploidies by isolating and analyzing fetal cells or free fetal DNA from maternal blood, avoiding risk to the fetus. However, a rapid, simple, consistent, and low-cost procedure suitable for routine clinical practice has not yet been achieved. The purpose of this study was to assess the feasibility of predicting fetal aneuploidy by applying our recently established dual-probe FISH protocol to fetal cells isolated and enriched from maternal blood. METHODS A total of 172 pregnant women underwent prospective testing for fetal aneuploidy by FISH analysis of fetal cells isolated from maternal blood. Results were compared with the karyotype determined through invasive procedures or at birth. RESULTS Seven of the samples exhibited fetal aneuploidy, which was confirmed by invasive prenatal diagnosis procedures. After enrichment for fetal cells, the frequency of trisomic cells was at least double in samples from aneuploid pregnancies (range 0.38-0.90%) compared to samples from normal pregnancies (≤0.18%). One false negative result was also obtained. CONCLUSIONS Noninvasive prenatal aneuploidy screening using fetal cells isolated from maternal blood is feasible and could substantially reduce the need for invasive procedures.

Abstract
Systemic lupus erythematosus (SLE) disproportionately affects women of reproductive age. During pregnancy, women are exposed to various sources of fetal material possibly constituting a significant immunologic exposure relevant to the development of SLE. The objective of this study was to investigate whether having any children who carry DRB1 alleles associated with SLE increase the risk of maternal SLE. This case-control study is based on the University of California, San Francisco Mother-Child Immunogenetic Study and from studies at the Inova Translational Medicine Institute. Analyses were conducted using data for 1304 mothers (219 cases/1085 controls) and their respective 1664 children. We selected alleles based on their known association with risk of SLE (DRB1*03:01, *15:01, or *08:01) or Epstein-Barr virus (EBV) glycoproteins (*04:01) due to the established EBV association with SLE risk. We used logistic regression models to estimate odds ratios (OR) and 95% confidence intervals (CI) for each allele of interest, taking into account maternal genotype and number of live births. We found an increase in risk of maternal SLE associated with exposure to children who inherited DRB1*04:01 from their father (OR 1.9; 95% CI, 1.1-3.2), among *04:01 allele-negative mothers. Increased risk was only present among mothers who were positive for one or more SLE risk-associated alleles (*03:01, *15:01 and/or *08:01). We did not find increased risk of maternal SLE associated with any other tested allele. These findings support the hypothesis that a child's alleles inherited from the father influence a mother's subsequent risk of SLE.

Abstract
BACKGROUND Porcine ulcerative dermatitis syndrome (PUDS) is a rare disease of breeding sows with an unknown pathogenesis. OBJECTIVE To describe the evolution of clinical and histopathological lesions over the course of the disease and to elucidate the pathogenesis. ANIMAL A 24-month-old, pluriparous, large white sow presented during gestation with ulcerations around the teats compatible with PUDS. METHODS AND RESULTS Clinical and histopathological lesions were monitored over the course of the disease (i.e. during and after the subsequent pregnancy). A clear gestation-dependent flare of the lesions was observed with partial resolution occurring postpartum. The histological pattern presented as a lymphocytic interface dermatitis. CONCLUSIONS AND CLINICAL IMPORTANCE The findings in this case report link gestation with the development of clinical signs and histological changes. Multiparity appears to enhance severity and may finally result in a self-perpetuating disease. Therefore, it seems advisable to cull breeding sows after they have developed PUDS.

Abstract
Fetal cells enter maternal circulation during pregnancy and persist in the woman’s body for decades, achieving a form of physiological microchimerism. These cells were also evidenced in tumors. We investigated the frequency and concentration of fetal microchimerism in the local breast cancer environment. From 19 patients with confirmed breast neoplasia, after breast surgical resection, we collected three fresh specimens from the tumor core, breast tissue at tumor periphery, and adjacent normal breast tissue. The presence of male DNA was analyzed with a quantitative PCR assay for the sex determining region gene (SRY) gene. In the group of women who had given birth to at least one son, we detected fetal microchimerism in 100% of samples from tumors and their periphery and in 64% (9 of 14) of those from normal breast tissue. The tissues from the tumor and its periphery carry a significantly increased number of SRY copies compared to its neighboring common breast tissue (p = 0.005). The median of the normalized SRY-signal was about 77 (range, 3.2–21467) and 14-fold (range, 1.3–2690) greater in the tumor and respectively in the periphery than in the normal breast tissue. In addition, the relative expression of the SRY gene had a median 5.5 times larger in the tumor than in its periphery (range, 1.1–389.4). We found a heterogeneous distribution of fetal microchimerism in breast cancer environment. In women with sons, breast neoplasia harbors male cells at significantly higher levels than in peripheral and normal breast tissue.

Abstract
The rate of inflammation increases in elderly individuals, a phenomenon called inflammaging, and is associated with degenerative diseases. However, the causes of inflammaging and the origin of the associated inflammatory mediators have remained enigmatic. We show herein that there is a positive correlation between the number of sons born and C-reactive protein concentrations in 90-year-old women. This association is influenced by HLA genetics known to regulate the immune response against HY antigens.

Abstract
BACKGROUND Fetal-maternal microchimerism (MC) can develop during pregnancy and may persist for decades. Pretransplantation fetal-maternal MC may be present between mother and child and between siblings; however, its effect on renal transplantation is not known. We investigated the effects of pretransplantation MC on allograft outcomes in human leukocyte antigen (HLA)-haploidentical family donor transplantation. METHODS A total of 106 cases transplanted from 1996 to 2004 were retrospectively studied, with median follow-up of 96 months. The study and control groups included 63 and 43 cases of HLA-haploidentical and HLA-identical donor transplantations, respectively. MC against mismatched donor HLA-DRB1 allele was detected in the recipient's peripheral blood using nested polymerase chain reaction-single-strand conformation polymorphism method. The allograft outcomes of HLA-haploidentical MC (+) and (-) subgroups were compared with those of HLA-identical group. RESULTS Pretransplantation MC in the HLA-haploidentical recipients was detected in 22.2% (14 of 63). Compared with HLA-identical group, MC (-) subgroup showed significantly inferior allograft outcomes: higher acute rejection rate (11.6% vs. 42.9%; P=0.001), higher 5-year serum creatinine level (1.1 vs. 1.4 mg/dL; P=0.009), and lower 10-year rejection-free survival rate (83.7% vs. 54.5%; log-rank P=0.001). In contrast, MC (+) subgroup showed no significant differences from HLA-identical group in acute rejection rate (14.3%), 5-year serum creatinine level (1.1 mg/dL), and 10-year rejection-free survival rate (85.7%). Multivariate analysis revealed that pretransplantation MC is associated with a significantly lower risk of acute rejection (odds ratio=0.10; P=0.021). CONCLUSION Pretransplantation MC present in the recipient may have beneficial effects on rejection-free allograft survival in renal transplantation.

Abstract
Autoimmune thyroid diseases (AITD) show a female predominance, with an increased incidence in the years following parturition. Fetal microchimerism has been suggested to play a role in the pathogenesis of AITD. However, only the presence of fetal microchimeric cells in blood and in the thyroid gland of these patients has been proven, but not an actual active role in AITD. Is fetal microchimerism harmful for the thyroid gland by initiating a Graft versus Host reaction (GvHR) or being the target of a Host versus Graft reaction (HvGR)? Is fetal microchimerism beneficial for the thyroid gland by being a part of tissue repair or are fetal cells just innocent bystanders in the process of autoimmunity? This review explores every hypothesis concerning the role of fetal microchimerism in AITD.

Abstract
Clinical observations suggest that pregnancy provides protection against cancer. The mechanisms involved, however, remain unclear. Fetal cells are known to enter the mother's circulation during pregnancy and establish microchimerism. We investigated if pregnancy-related embryonic/fetal stem cell integration plays a role in breast cancer. A high-sensitivity Y-chromosome assay was developed to trace male allogeneic cells (from male fetus) in females. Fixed-embedded samples (n = 206) from both normal and breast cancer patients were screened for microchimerism. The results were combined with matching clinicopathological and histological parameters and processed statistically. The results show that in our samples (182 informative) more than half of healthy women (56%) carried male cells in their breast tissue for decades (n = 68), while only one out of five in the cancer sample pool (21%) (n = 114) (odds ratio = 4.75, CI at 95% 2.34-9.69; p = 0.0001). The data support the notion that a biological link may exist between chimerism and tissue-integrity. The correlation, however, is non-linear, since male microchimerism in excess ("hyperchimerism") is also involved in cancer. The data suggest a link between hyperchimerism and HER2-type cancers, while decreased chimerism ("hypochimerism") associates with ER/PR-positive (luminal-type) breast cancers. Chimerism levels that correlate with protection appear to be non-random and share densities with the mammary progenitor components of the stem cell lineage in the breast. The results suggest that protection may involve stem/progenitor level interactions and implicate novel quantitative mechanisms in chimerism biology.

Abstract
Embryonic, adult, artificially reprogrammed, and cancer…- there are various types of cells associated with stemness. Do they have something fundamental in common? Are we applying a common name to very different entities? In this review, we will revisit the characteristics that define 'pluripotency', the main property of stem cells (SCs). For each main type of physiological (embryonic and adult) or synthetic (induced pluripotent) SCs, markers and functional behavior in vitro and in vivo will be described. We will review the pioneering work that has led to obtaining human SC lines, together with the problems that have arisen, both in a biological context (DNA alterations, heterogeneity, tumors, and immunogenicity) and with regard to ethical concerns. Such problems have led to proposals for new operative procedures for growing human SCs of sufficiently high quality for use as models of disease and in human therapy. Finally, we will review the data from the first clinical trials to use various types of SCs.

Abstract
Microchimerism is the presence of cells from one individual in another genetically distinct individual. Pregnancy is the main cause of natural microchimerism through transplacental bidirectional cell trafficking between mother and fetus. The consequences of pregnancy-related microchimerism are under active investigation. However, many authors have suggested a close relationship linking fetal microchimerism and the development of autoimmune diseases. It has been more than ten years now since the demonstration of the presence of a significant high number of fetal microchimeric cells residing in thyroid glands from operated patients with Graves' disease. This intrathyroidal fetal microchimerism is an attractive candidate mechanism for the modulation of Graves' disease in pregnancy and the postpartum period.

Abstract
Given the shortage of human organs for transplantation, the waiting lists are increasing annually and consequently so is the time and deaths during the wait. As most immune suppression therapy is not antigen specific and the risk of infection tends to increase, scientists are looking for new options for immunosuppression or immunotolerance. Tolerance induction would avoid the complications caused by immunosupressive drugs. As such, taking into account the experience with autoimmune diseases, one strategy could be immune modulation-induced changes in T-cell cytokine secretion or antigen therapy; however, most clinical trials have failed. Gene transfer of MHC genes across species may be used to induce tolerance to xenogenic solid organs. Other options are induction of central tolerance by the establishment of mixed chimerism through hematopoietic stem cell transplantation and the induction of 'operational tolerance' through immunodeviation involving dendritic or Tregs. I propose that, as the recognition and tolerance of proteins takes place in the thymus, this organ should be the main target for immunotolerance research protocols even as early as during the fetal development.

Abstract
During pregnancy women can develop B- and T-cell immunity against the inherited paternal antigens (IPAs) of the fetus, such as HLA, peptides of minor histocompatibilty antigens, and possibly onco-fetal antigens. The biological and pathological role of these pregnancy-induced immunological events is only understood in part. However, anti-IPA immunity in the mother persists for many decades after delivery and may reduce relapse in offspring with leukemia after HLA-haploidentical transplantation of maternal hematopoietic stem cells (HSC). We hypothesized that maternal anti-IPA immune elements cross the placenta and might confer a potent graft-versus-leukemia effect when cord blood (CB) is used in unrelated HSC transplantation. In a retrospective study of single-unit CB recipients with all grafts provided by the New York Blood Center, we show that patients with acute myeloid or lymphoblastic leukemia (n = 845) who shared one or more HLA-A, -B, or -DRB1 antigens with their CB donor's IPAs had a significant decrease in leukemic relapse posttransplantation [hazard ratio (HR) = 0.38, P < 0.001] compared with those that did not. Remarkably, relapse reduction in patients receiving CB with one HLA mismatch (HR = 0.15, P < 0.001) was not associated with an increased risk of severe acute graft-versus-host disease (HR = 1.43, P = 0.730). Our findings may explain the unexpected low relapse rate after CB transplantation, open new avenues in the study of leukemic relapse after HSC transplantation (possibly of malignancies in general), and have practical implications for CB unit selection.

Abstract
RATIONALE Fetal cells enter the maternal circulation during pregnancy and may persist in maternal tissue for decades as microchimeras. OBJECTIVE Based on clinical observations of peripartum cardiomyopathy patients and the high rate of recovery they experience from heart failure, our objective was to determine whether fetal cells can migrate to the maternal heart and differentiate to cardiac cells. METHODS AND RESULTS We report that fetal cells selectively home to injured maternal hearts and undergo differentiation into diverse cardiac lineages. Using enhanced green fluorescent protein (eGFP)-tagged fetuses, we demonstrate engraftment of multipotent fetal cells in injury zones of maternal hearts. In vivo, eGFP+ fetal cells form endothelial cells, smooth muscle cells, and cardiomyocytes. In vitro, fetal cells isolated from maternal hearts recapitulate these differentiation pathways, additionally forming vascular tubes and beating cardiomyocytes in a fusion-independent manner; ≈40% of fetal cells in the maternal heart express Caudal-related homeobox2 (Cdx2), previously associated with trophoblast stem cells, thought to solely form placenta. CONCLUSIONS Fetal maternal stem cell transfer appears to be a critical mechanism in the maternal response to cardiac injury. Furthermore, we have identified Cdx2 cells as a novel cell type for potential use in cardiovascular regenerative therapy.

Abstract
Detection of chromosomal aneuploidies using fetal cells isolated from maternal blood, for prenatal non-invasive genetic investigation, has been a long-sought goal of clinical genetics to replace amniocentesis and chorionic villous sampling to avoid any risk to the fetus. The purpose of this study was to develop a sensitive and specific new assay for diagnosing aneuploidy with circulating fetal cells isolated from maternal blood as previously reported using two novel approaches: (i) simultaneous immunocytochemistry (ICC) evaluation using a monoclonal antibody for i-antigen, followed by fluorescence in situ hybridization (FISH); (ii) dual-probe FISH analysis of interphase nuclei using two differently labeled probes, specific for different loci of chromosomes 21 and 18; in addition, short tandem repeats (STR) analysis on single cells isolated by micromanipulation was applied to confirm the presence of fetal cells in the cell sample enriched from maternal blood. Blood samples were obtained from women carrying trisomic fetuses, and from non-pregnant women and men as controls. Using ICC-FISH approach, a large heterogeneity in immunostaining pattern was observed, which is a source of very subjective signal interpretation. Differently, dual-probe FISH analysis provided for a correct diagnosis of all pregnancies: the mean percentage of trisomic cells was 0.5% (range, 0.36-0.76%), while the mean percentage of trisomic cells in the control group (normal pregnancies or non-pregnant women) was ≤0.20%. The application of the dual-probe FISH protocol on fetal cells isolated from maternal blood enables accurate molecular detection of fetal aneuploidy, thus providing a foundation for development of non-invasive prenatal diagnostic testing.

Abstract
CONTEXT Stem cells are undifferentiated cells with the property of self-renewal and give rise to highly specialized cells under appropriate local conditions. The use of stem cells in regenerative medicine holds great promise for the treatment of many diseases, including those of the thyroid gland. EVIDENCE ACQUISITION This review focuses on the progress that has been made in thyroid stem cell research including an overview of cellular and molecular events (most of which were drawn from the period 1990-2011) and discusses the remaining problems encountered in their differentiation. EVIDENCE SYNTHESIS Protocols for the in vitro differentiation of embryonic stem cells, based on normal developmental processes, have generated thyroid-like cells but without full thyrocyte function. However, agents have been identified, including activin A, insulin, and IGF-I, which are able to stimulate the generation of thyroid-like cells in vitro. In addition, thyroid stem/progenitor cells have been identified within the normal thyroid gland and within thyroid cancers. CONCLUSIONS Advances in thyroid stem cell biology are providing not only insight into thyroid development but may offer therapeutic potential in thyroid cancer and future thyroid cell replacement therapy.

Abstract
Microchimerism has been studied in the context of a variety of diseases which include autoimmune diseases (such as systemic sclerosis, rheumatoid arthritis, systemic lupus erythematosus and autoimmune thyroid diseases), cancer (e.g., of the cervix, thyroid gland, lung, breast), tissue repair, transplantation and transfusion. It may become relevant in the context of cell-based non-invasive prenatal diagnosis. But how to safely identify individual microchimeric cells? This is a nontrivial question, for which a solution has recently been suggested.

Abstract
The extreme polymorphism of mammalian major histocompatibility (MHC) Class I and Class II alleles has been attributed to inbreeding avoidance, heterozygote advantage and pathogen driven selection for rare MHC alleles. However, MHC alleles can be classified into a limited number of allele supertypes based on the specificity of their peptide binding grooves (about 10 supertypes in the case of human MHC Class I alleles). The paradox is that if antigen presentation can be accomplished by a limited number of binding groove motifs, why are these loci so polymorphic? An unexplored driver of this complexity may be selection pressure to enhance the antigenicity and immune recognition of transplacentally acquired lymphoid allografts during pregnancy. The exchange of lymphoid cells between mother and fetus probably occurs in all pregnancies and may lead to fetal and/or maternal lymphoid microchimerism, a known cause of autoimmune disease. Natural selection may have favoured increased polymorphism at MHC Class I and Class II loci in order to improve immune surveillance of these cells and thereby reduce the incidence of maternal and fetal autoimmune disease. At the same time, selection may have favoured the retention of a limited set of allele supertypes which optimally present immunodominant antigens.

Abstract
Autoimmune diseases (AID) predominantly affect women of reproductive age. While
basic molecular studies have implicated persisting fetal cells in the mother in
some AID, supportive epidemiological evidence is limited. We investigated the
effect of vaginal delivery, caesarean section (CS) and induced abortion on the
risk of subsequent maternal AID. Using the Danish Civil Registration System
(CRS) we identified women who were born between 1960 and1992. We performed data
linkage between the CRS other Danish national registers to identify women who
had a pregnancy and those who developed AID. Women were categorised into 4
groups; nulligravida (control group), women who had 1st child by vaginal
delivery, whose 1st delivery was by CS and who had abortions. Log-linear Poisson
regression with person-years was used for data analysis adjusting for several
potential confounders. There were 1,035,639 women aged >14 years and 25,570
developed AID: 43.4% nulligravida, 44.3% had their first pregnancy
delivered vaginally, 7.6% CS and 4.1% abortions. The risk of AID
was significantly higher in the 1st year after vaginal delivery
(RR = 1.1[1.0, 1.2]) and CS
(RR = 1.3[1.1, 1.5]) but significantly lower in
the 1st year following abortion (RR = 0.7[0.6,
0.9]). These results suggest an association between pregnancy and the risk
of subsequent maternal AID. Increased risks of AID after CS may be explained by
amplified fetal cell traffic at delivery, while decreased risks after abortion
may be due to the transfer of more primitive fetal stem cells. The increased
risk of AID in the first year after delivery may also be related to greater
testing during pregnancy.

Abstract
Fetal cell microchimerism is defined as the persistence of fetal cells in the mother after birth without any apparent rejection. Fetal microchimeric cells (FMCs) engraft into the maternal bone marrow for decades after delivery and are able to migrate to blood and tissues. This phenomenon was hypothesized to have a detrimental role in autoimmune diseases, but data are still controversial and debated. In malignant tumors, fetal cell microchimerism has been postulated to have a positive effect on tumor burden, although some evidence suggests that FMCs may be involved in neoplastic progression. At the peripheral level, circulating FMCs are less frequently detected in patients with thyroid cancer, breast cancer or other solid, hematologic malignancies than in healthy individuals, which suggests a protective role for fetal cell microchimerism. In tissues, FMCs have been found in tumor sections from malignancies such as thyroid, breast, cervix, lung cancers and melanomas and have been shown to differentiate into epithelial, hematopoietic, endothelial and mesenchymal cells. FMCs with hematopoietic differentiation have been postulated to have a role in destroying the tumor, whereas mesenchymal and epithelial cells could participate in repair processes. Endothelial cells, on the other hand, are believed to play a part in tumor progression. This Review provides an overview of the role of fetal cell microchimerism in autoimmune and benign or malignant nonautoimmune diseases. Moreover, the mechanisms by which fetal cell microchimerism is believed to modulate the protection against cancer or tumor progression will be discussed, together with future research directions.

Abstract
During pregnancy, due to the bidirectional traffic through the placenta, chimera cells or DNA gets into the mother's and her fetus' body. This is the phenomenon of fetal and maternal microchimerism. These cells, even decades after the birth, can be detected in the host. Despite the fact that a lot of research-team deals with this phenomenon, the importance of microchimerism in health and diseases remains little known. In this article, we aimed to give an overview of the current state of science about this topic. The possible role of microchimerism studied mostly in the pathogenesis of autoimmune processes, non-autoimmune diseases and tumors, or even in the regression of them; it can be as well as a possible component of transplant immunology. The phenomenon of microchimerism could mean important opportunity in the non-invasive prenatal diagnosis, cutting off the currently associated risk of abortion. Due to the constantly developing cell identification- and enrichment procedures, it is expected to be revealed in more and more processes of the human body, that microchimera cells and DNA, as an inheritance of pregnancy, play a role in them.

Abstract
The use of neuroprotective therapies begs the question of how such therapies could affect preexisting stem cell populations within the host, as well as those introduced through cell-replacement therapy. Multiple mechanisms may mediate stem cell responses to neuroprotectants such as host/donor age and gender, cellular lineage/differentiation status, and mitochondrial dynamics. Current therapeutic sources for stem cells are embryonic, somatic, or induced pluripotent, with very little known about the effects of gender, age, cell type, and mitochondrial dynamics. With the advent of therapies to stimulate and recruit endogenous stem cells or transplant donor cells into damage areas in the hopes of recuperative regeneration of lost neurons, it is important to discuss mechanisms that dictate the winning players in the neuroprotection game. This review will focus on our current understanding of the characteristics of renewing stem cells that may affect neuroprotection.

Abstract
BACKGROUND AIMS Chimerism is an important outcome measure in hematopoietic cell transplantation as well as somatic cell therapy. Commonly used methods to estimate chimerism are restricted by either gender or inefficient sensitivity. In principle, real-time polymerase chain reaction (PCR)-based assays can be used to assess single nucleotide polymorphisms (SNP), which are a vast resource of molecular markers, and such assays demonstrate a substantially higher sensitivity (0.001%), but the specificity is unclear because of a low-level signal from mismatched sequences. METHODS In this study, we cloned 14 pairs of SNP selected from the SNP HapMap database and examined the specificity and sensitivity of their detection by real-time PCR using two primer/fluorescent probe pairs to allow genotyping of the two possible variant alleles. Clinical donor-recipient pairs from 18 families were used to explore the efficacy of using SNP assays to measure chimerism. RESULTS We found that the polymorphic nucleotide influences the ability to distinguish the signal generated by the target and mismatched sequences. Moreover, the specific fluorescent reporter probe can affect the difference in signal intensity between the target and mismatched sequences. Real-time PCR SNP assays can attain a sensitivity of 0.1-0.5% with 100% specificity. When comparing possible clinical donor-recipient pairs, we found an average 3.3 out of 14 SNP were informative. CONCLUSIONS By optimal selection of the polymorphic sequences and fluorescent reporter, the real-time PCR SNP assay is superior to the short-tandem repeat chimerism assay and broadly applicable. This strategy may be applied in future clinical trials of bone marrow cell therapy.

Abstract
BACKGROUND Thyroid gland development and function are essential for life, and recent findings indicate the presence of stem/progenitor cells within the thyroid gland as a potential source of tissue regeneration and cancer formation. SUMMARY This review summarizes the current knowledge on early differentiation of thyroid cells from embryonic stem cells and highlights exciting concepts and recent novel findings on adult thyroid stem/progenitor cells in the normal thyroid gland and in thyroid cancer. Other potential sources and markers of stem/progenitor cells in the thyroid include bone marrow, microchimerism, and embryological remnant-derived multifocal solid cell nests. Finally, we discuss new therapeutic strategies that target thyroid cancer stem cells. CONCLUSIONS Thyroid stem/progenitor cell populations are present in the normal and diseased thyroid gland. Advances in normal and cancer thyroid stem cell biology will be essential for future targeted therapies.
