Abstract
The COVID-19 pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), still remains a severe threat. At the time of writing this paper, the second infectious wave has caused more than 280,000 deaths all over the world. Italy was one of the first countries involved, with more than 200,000 people reported as infected and 30,000 deaths. There are no specific treatments for COVID-19 and the vaccine still remains somehow inconclusive. The world health community is trying to define and share therapeutic protocols in early and advanced clinical stages. However, numbers remain critical with a serious disease rate of 14%, ending with sepsis, acute respiratory distress syndrome (ARDS), multiple organ failure (MOF) and vascular and thromboembolic findings. The mortality rate was estimated within 2-3%, and more than double that for individuals over 65 years old; almost one patient in three dies in the Intensive Care Unit (ICU). Efforts for effective solutions are underway with multiple lines of investigations, and health authorities have reported success treating infected patients with donated plasma from survivors of the illness, the proposed benefit being protective antibodies formed by the survivors. Plasma transfusion, blood and stem cells, either autologous or allograft transplantation, are not novel therapies, and in this short paper, we propose therapeutic autologous plasma and peripheral blood stem cells as a possible treatment for fulminant COVID-19 infection.

Abstract
Cell fusion is involved in the development of some adult organs, is implicated in the pathogenesis of specific types of cancer, and is known to participate in repair/regeneration processes mediated by bone-marrow-derived cells (BMDCs). Endometriosis is a disease characterized by growth of functional endometrial tissue outside of the uterine cavity. Endometriosis shares some molecular properties with cancer and BMDCs home to endometriosis lesions in a mouse model. Our objective was to determine if cell fusion can occur in endometriosis and establish whether bone-marrow-derived cells participate in cell fusion events in lesions. We employed a Cre-Lox system to identify cell fusion events in a mouse model of endometriosis. Fused cells were detected in endometriotic lesions, albeit at a low frequency (∼1 in 400 cells), localized to the stromal compartment, and displayed restricted proliferation. Using 5-fluorouracil-based nongonadotoxic bone marrow transplantation model, we demonstrate that bone marrow cells represent a principal cell source for fusion events in lesions. Cell fusion progeny uniformly lacked expression of selected markers of hematopoietic, endothelial, and epithelial markers, though they expressed the mesenchymal/stromal markers Sca-1 and CD29. This study is the first to describe the phenomenon of cell fusion in endometriosis and points to a mesenchymal population derived from cell fusion events with limited proliferative activity, properties previously attributed to endometrial stem cells. Their putative role in the pathogenesis of the disease remains to be elucidated.

Abstract
Alveolar type 2 progenitor cells (AT2) seem closest to clinical translation, specifying the evidence that AT2 may satisfactorily control the immune response to decrease lung injury by stabilizing host immune-competence and a classic and crucial resource for lung regeneration and repair. AT2 establish potential in benefiting injured lungs. However, significant discrepancies linger in our understanding vis-à-vis the mechanisms for AT2 as a regime for stem cell therapy as well as essential guiding information for clinical trials, including effectiveness in appropriate pre-clinical models, safety, mostly specifications for divergent lung injury patients. These important gaps shall be systematically investigated prior to the vast therapeutic perspective of AT2 cells for pulmonary diseases can be considered. This review focused on AT2 cells homeostasis, pathophysiological changes in the pathogenesis of lung injury, physiological function of AT2 cells, apoptosis of AT2 cells in lung diseases, the role of AT2 cells in repairing processes after lung injury, mechanism of AT2 cells activation promote repairing processes after lung injury, and potential therapy of lung disease by utilizing the AT2 progenitor cells. The advancement remains to causally connect the molecular and cellular alteration of AT2 cells to lung injury and repair. Conclusively, it is identified that AT2 cells can convert into AT1 cells; but, the comprehensive cellular mechanisms involved in this transition are unrevealed. Further investigation is mandatory to determine new strategies to prevent lung injury.

Abstract
Advances in stem cell biology and materials science have provided a basis for developing tissue engineering methods to repair muscle injury. Among stem cell populations with potential to aid muscle repair, adipose-derived mesenchymal stem cells (ASC) hold great promise. To evaluate the possibility of using porcine ASC for muscle regeneration studies, we co-cultured porcine ASC with murine C2C12 myoblasts. These experiments demonstrated that porcine ASC display significant myogenic potential. Co-culture of ASC expressing green fluorescent protein (GFP) with C2C12 cells resulted in GFP+ myotube formation, indicating fusion of ASC with myoblasts to form myotubes. The presence of porcine lamin A/C positive nuclei in myotubes and RTqPCR analysis of porcine myogenin and desmin expression confirmed that myotube nuclei derived from ASC contribute to muscle gene expression. Co-culturing GFP+ASC with porcine satellite cells demonstrated enhanced myogenic capability of ASC, as the percentage of labeled myotubes increased compared to mouse co-cultures. Enhancing myogenic potential of ASC through soluble factor treatment or expansion of ASC with innate myogenic capacity should allow for their therapeutic use to regenerate muscle tissue lost to disease or injury.

Abstract
Cigarette smoke exposure causes chronic oxidative lung damage. During pregnancy, fetal microchimeric cells traffic to the mother. Their numbers are increased at the site of acute injury. We hypothesized that milder chronic diffuse smoke injury would attract fetal cells to maternal lungs. We used a green-fluorescent-protein (GFP) mouse model to study the effects of cigarette smoke exposure on fetomaternal cell trafficking. Wild-type female mice were exposed to cigarette smoke for about 4 weeks and bred with homozygote GFP males. Cigarette smoke exposure continued until lungs were harvested and analyzed. Exposure to cigarette smoke led to macrophage accumulation in the maternal lung and significantly lower fetal weights. Cigarette smoke exposure influenced fetomaternal cell trafficking. It was associated with retention of GFP-positive fetal cells in the maternal lung and a significant reduction of fetal cells in maternal livers at gestational day 18, when fetomaternal cell trafficking peaks in the mouse model. Cells quickly clear postpartum, leaving only a few, difficult to detect, persisting microchimeric cells behind. In our study, we confirmed the postpartum clearance of cells in the maternal lungs, with no significant difference in both groups. We conclude that in the mouse model, cigarette smoke exposure during pregnancy leads to a retention of fetal microchimeric cells in the maternal lung, the site of injury. Further studies will be needed to elucidate the effect of cigarette smoke exposure on the phenotypic characteristics and function of these fetal microchimeric cells, and confirm its course in cigarette smoke exposure in humans.

Abstract
Chronic lung diseases, such as cystic fibrosis (CF), asthma, and chronic obstructive pulmonary disease (COPD) are incurable and represent a very high social burden. Stem cell-based treatment may represent a hope for the cure of these diseases. In this paper, we revise the overall knowledge about the plasticity and engraftment of exogenous marrow-derived stem cells into the lung, as well as their usefulness in lung repair and therapy of chronic lung diseases. The lung is easily accessible and the pathophysiology of these diseases is characterized by injury, inflammation, and eventually by remodeling of the airways. Bone marrow-derived stem cells, including hematopoietic stem/progenitor cells (HSPCs) and mesenchymal stromal (stem) cells (MSCs), encompass a wide array of cell subsets with different capacities of engraftment and injured tissue regenerating potential. Proof-of-principle that marrow cells administered locally may engraft and give rise to specialized epithelial cells has been given, but the efficiency of this conversion is too limited to give a therapeutic effect. Besides the identification of plasticity mechanisms, the characterization/isolation of the stem cell subpopulations represents a major challenge to improving the efficacy of transplantation protocols used in regenerative medicine for lung diseases.

Abstract
BACKGROUND Definite identification of the cell types and the mechanism relevant to cardiomyogenesis is essential for effective cardiac regenerative medicine. We aimed to identify the cell populations that can generate cardiomyocytes and to clarify whether generation of donor-marker(+) cardiomyocytes requires cell fusion between BM-derived cells and recipient cardiomyocytes. METHODOLOGY/PRINCIPAL FINDINGS Purified BM stem/progenitor cells from green fluorescence protein (GFP) mice were transplanted into C57BL/6 mice or cyan fluorescence protein (CFP)-transgenic mice. Purified human hematopoietic stem cells (HSCs) from cord blood were transplanted into immune-compromised NOD/SCID/IL2rγ(null) mice. GFP(+) cells in the cardiac tissue were analyzed for the antigenecity of a cardiomyocyte by confocal microscopy following immunofluorescence staining. GFP(+) donor-derived cells, GFP(+)CFP(+) fused cells, and CFP(+) recipient-derived cells were distinguished by linear unmixing analysis. Hearts of xenogeneic recipients were evaluated for the expression of human cardiomyocyte genes by real-time quantitative polymerase chain reaction. In C57BL/6 recipients, Lin(-/low)CD45(+) hematopoietic cells generated greater number of GFP(+) cardiomyocytes than Lin(-/low)CD45(-) mesenchymal cells (37.0+/-23.9 vs 0.00+/-0.00 GFP(+) cardiomyocytes per a recipient, P = 0.0095). The number of transplanted purified HSCs (Lin(-/low)Sca-1(+) or Lin(-)Sca-1(+)c-Kit(+) or CD34(-)Lin(-)Sca-1(+)c-Kit(+)) showed correlation to the number of GFP(+) cardiomyocytes (P<0.05 in each cell fraction), and the incidence of GFP(+) cardiomyocytes per injected cell dose was greatest in CD34(-)Lin(-)Sca-1(+)c-Kit(+) recipients. Of the hematopoietic progenitors, total myeloid progenitors generated greater number of GFP(+) cardiomyocytes than common lymphoid progenitors (12.8+/-10.7 vs 0.67+/-1.00 GFP(+) cardiomyocytes per a recipient, P = 0.0021). In CFP recipients, all GFP(+) cardiomyocytes examined coexpressed CFP. Human troponin C and myosin heavy chain 6 transcripts were detected in the cardiac tissue of some of the xenogeneic recipients. CONCLUSIONS/SIGNIFICANCE Our results indicate that HSCs resulted in the generation of cardiomyocytes via myeloid intermediates by fusion-dependent mechanism. The use of myeloid derivatives as donor cells could potentially allow more effective cell-based therapy for cardiac repair.

Abstract
Previous studies have demonstrated that bone marrow (BM)-derived cells differentiate into nonhematopoietic cells of multiple tissues. To date, it remains unknown which population(s) of BM cells are primarily responsible for this engraftment. To test the hypothesis that nonhematopoietic stem cells in the BM are the primary source of marrow-derived lung epithelial cells, either wild-type hematopoietic or nonhematopoietic BM cells were transplanted into irradiated surfactant-protein-C (SPC)-null mice. Donor-derived, SPC-positive type 2 pneumocytes were predominantly detected in the lungs of mice receiving purified nonhematopoietic cells and were absent from mice receiving purified hematopoietic stem and progenitor cells. We conclude that cells contained in the nonhematopoietic fraction of the BM are the primary source of marrow-derived lung epithelial cells. These nonhematopoietic cells may represent a primitive stem cell population residing in adult BM.

Abstract
Accumulated evidence demonstrates the existence of bone marrow-derived cells origin in the endometria of women undergoing bone marrow transplantation (BMT). In these reports, cells of a bone marrow (BM) origin are able to differentiate into endometrial cells, although their contribution to endometrial regeneration is not yet clear. We have previously demonstrated the functional relevance of side population (SP) cells as the endogenous source of somatic stem cells (SSC) in the human endometrium. The present work aims to understand the presence and contribution of bone marrow-derived cells to the endometrium and the endometrial SP population of women who received BMT from male donors. Five female recipients with spontaneous or induced menstruations were selected and their endometrium was examined for the contribution of XY donor-derived cells using fluorescent in situ hybridization (FISH), telomapping and SP method investigation. We confirm the presence of XY donor-derived cells in the recipient endometrium ranging from 1.7% to 2.62%. We also identify 0.45-0.85% of the donor-derived cells in the epithelial compartment displaying CD9 marker, and 1.0-1.83% of the Vimentin-positive XY donor-derived cells in the stromal compartment. Although the percentage of endometrial SP cells decreased, possibly being due to chemotherapy applied to these patients, they were not formed by XY donor-derived cells, donor BM cells were not associated with the stem cell (SC) niches assessed by telomapping technique, and engraftment percentages were very low with no correlation between time from transplant and engraftment efficiency, suggesting random terminal differentiation. In conclusion, XY donor-derived cells of a BM origin may be considered a limited exogenous source of transdifferentiated endometrial cells rather than a cyclic source of BM donor-derived stem cells.

Abstract
The therapeutic potential of stem cells in chronic obstructive pulmonary disease is not well known although stem cell therapy is effective in models of other pulmonary diseases. We tested the capacities of bone marrow cells (BMCs), mesenchymal stem cells (MSCs), and conditioned media of MSCs (MSC-CM) to repair cigarette smoke-induced emphysema. Inbred female Lewis rats were exposed to cigarette smoke for 6 mo and then received BMCs, MSCs, or MSC-CM from male Lewis rats. For 2 mo after injection, the BMC treatment gradually alleviated the cigarette smoke-induced emphysema and restored the increased mean linear intercept. The BMC treatment significantly increased cell proliferation and the number of small pulmonary vessels, reduced apoptotic cell death, attenuated the mean pulmonary arterial pressure, and inhibited muscularization in small pulmonary vessels. However, only a few male donor cells were detected from 1 day to 1 mo after BMC administration. The MSCs and cell-free MSC-CM also induced the repair of emphysema and increased the number of small pulmonary vessels. Our data show that BMC, MSCs, and MSC-CM treatment repaired cigarette smoke-induced emphysema. The repair activity of these treatments is consistent with a paracrine effect rather than stem cell engraftment because most of the donor cells disappeared and because cell-free MSC-CM also induced the repair.

Abstract
Cell-cell fusion is a natural process that occurs not only during development, but as has emerged over the last few years, also with an important role in tissue regeneration. Interestingly, in-vitro studies have revealed that after fusion of two different cell types, the developmental potential of these cells can change. This suggests that the mechanisms by which cells differentiate during development to acquire their identities is not irreversible, as was considered until a few years ago. To date, it is well established that the fate of a cell can be changed by a process known as reprogramming. This mainly occurs in two different ways: the differentiated state of a cell can be reversed back into a pluripotent state (pluripotent reprogramming), or it can be switched directly to a different differentiated state (lineage reprogramming). In both cases, these possibilities of obtaining sources of autologous somatic cells to maintain, replace or rescue different tissues has provided new and fundamental insights in the stem-cell-therapy field. Most interestingly, the concept that cell reprogramming can also occur in vivo by spontaneous cell fusion events is also emerging, which suggests that this mechanism can be implicated not only in cellular plasticity, but also in tissue regeneration. In this chapter, we will summarize the present knowledge of the molecular mechanisms that mediate the restoration of pluripotency in vitro through cell fusion, as well as the studies carried out over the last 3 decades on lineage reprogramming, both in vitro and in vivo. How the outcome of these studies relate to regenerative medicine applications will also be discussed.

Abstract
Cell-based therapies with embryonic or adult stem cells, including induced pluripotent stem cells, have emerged as potential novel approaches for several devastating and otherwise incurable lung diseases, including emphysema, pulmonary fibrosis, pulmonary hypertension, and the acute respiratory distress syndrome. Although initial studies suggested engraftment of exogenously administered stem cells in lung, this is now generally felt to be a rare occurrence of uncertain physiologic significance. However, more recent studies have demonstrated paracrine effects of administered cells, including stimulation of angiogenesis and modulation of local inflammatory and immune responses in mouse lung disease models. Based on these studies and on safety and initial efficacy data from trials of adult stem cells in other diseases, groundbreaking clinical trials of cell-based therapy have been initiated for pulmonary hypertension and for chronic obstructive pulmonary disease. In parallel, the identity and role of endogenous lung progenitor cells in development and in repair from injury and potential contribution as lung cancer stem cells continue to be elucidated. Most recently, novel bioengineering approaches have been applied to develop functional lung tissue ex vivo. Advances in each of these areas will be described in this review with particular reference to animal models.

Abstract
Bone marrow-derived progenitor cells can fuse with cells of several different tissues, including lung, especially following injury. Despite many reports of cell fusion, few studies have examined the function of the resulting hybrid cells. We cocultured human multipotent stromal cells (hMSCs) and normal human bronchial epithelial cells (NHBEs) and observed the formation of hMSC/NHBE heterokaryons. The heterokaryons expressed several proteins characteristic of epithelial cells, such as keratin and occludin. Hybrid cells also expressed the mRNAs and proteins for 2 important ion channels that maintain bronchial and alveolar fluid balance: the cystic fibrosis transmembrane conductance regulator (CFTR) and the amiloride-sensitive epithelial Na(+) channel (ENaC). By immunocytochemistry, CFTR was expressed in many hybrid cells but was absent or low in others. Whole-cell patch-clamp recordings demonstrated a glibenclamide-sensitive current in the presence of barium chloride, consistent with functional CFTR channels, in control NHBEs and hMSC/NHBE heterokaryons. Total cell capacitance measurements showed that the membrane surface area of heterokaryons was similar to that of NHBEs. Heterokaryons expressed the α- and γ-ENaC subunits but did not express the β-ENaC subunit, indicating the inability to form a complete ENaC channel. In addition, hybrid cells formed by the fusion of hMSCs with immortalized bronchial cells that expressed CFTR ΔF508 did not lead to reprogramming of the hMSC nucleus and expression of wild-type CFTR mRNA. Our data show that reprogramming can be incomplete following fusion of adult progenitor cells and somatic cells and may lead to altered cell function.

Abstract
Although cystic fibrosis (CF), an autosomal recessive disease caused by mutations in the gene encoding for the CF transmembrane conductance regulator (CFTR), seems a good candidate for gene therapy, 15 years of intense investigation and a number of clinical trials have not yet produced a viable clinical gene-therapy strategy. In addition, the duration of gene expression has been shown to be limited, only lasting 1-4 weeks. Therefore, alternative approaches involve the search for, and use of, stem cell populations. Bone marrow contains different stem cell types, including hematopoietic stem cells and multipotent mesenchymal stromal cells. Numerous studies have now demonstrated the ability of hematopoietic stem cells and mesenchymal stromal cells to home to the lung and differentiate into epithelial cells of both the conducting airways and the alveolar region. However, engraftment of bone marrow-derived stem cells into the airways is a very inefficient process. Detailed knowledge of the cellular and molecular determinants governing homing to the lung and transformation of marrow cells into lung epithelial cells would benefit this process. Despite a very low level of engraftment of donor cells into the nose and gut, significant CFTR mRNA expression and a measurable level of correction of the electrophysiological defect were observed after transplantation of wild-type marrow cells into CF mice. It is uncertain whether this effect is due to the presence of CFTR-expressing epithelial cells derived from donor cells or to the immunomodulatory role of transplanted cells. Finally, initial studies on the usefulness of umbilical cord blood and embryonic stem cells in the generation of airway epithelial cells will be discussed in this review.

Abstract
The aim of this study was to test the hypothesis that bone marrow mononuclear cell (BMDMC) therapy led an improvement in lung mechanics and histology in endotoxin-induced lung injury. Twenty-four C57BL/6 mice were randomly divided into four groups (n = 6 each). In the acute lung injury (ALI) group, Escherichia coli lipopolysaccharide (LPS) was instilled intratracheally (40 μg, IT), and control (C) mice received saline (0.05 ml, IT). One hour after the administration of saline or LPS, BMDMC (2 × 10(7) cells) was intravenously injected. At day 28, animals were anesthetized and lung mechanics [static elastance (E(st)), resistive (ΔP(1)), and viscoelastic (ΔP(2)) pressures] and histology (light and electron microscopy) were analyzed. Immunogold electron microscopy was used to evaluate if multinucleate cells were type II epithelial cells. BMDMC therapy prevented endotoxin-induced lung inflammation, alveolar collapse, and interstitial edema. In addition, BMDMC administration led to epithelial and endothelial repair with multinucleated type II pneumocytes. These histological changes yielded a reduction in lung E(st), ΔP(1), and ΔP(2) compared to ALI. In the present experimental ALI model, the administration of BMDMC yielded a reduction in the inflammatory process and a repair of epithelium and endothelium, reducing the amount of alveolar collapse, thus leading to an improvement in lung mechanics.

Abstract
Studies on the ability of bone marrow-derived cells to adopt the morphology and protein expression pattern of epithelial cells in vivo have expanded rapidly during the last decade, and hundreds of publications report that bone marrow-derived cells can become epithelial cells of multiple organs, including lung, liver, gastrointestinal tract, skin, pancreas, and others. In this review, we critically evaluate the literature related to engraftment of bone marrow-derived cells as epithelial cells in the lung. More than 40 articles focused on whether bone marrow cells can differentiate into lung epithelial cells have been published, nearly all of which claim to identify marrow-derived epithelial cells. A few investigations have concluded that no such cells are present and that the phenomenon of marrow-derived epithelial cells is based on detection artifacts. Here we discuss the problems that exist in published articles identifying marrow-derived epithelial cells, and propose standards for detection methods that provide the most definitive data. Identification of bone marrow-derived epithelial cells requires reliable and sensitive techniques for their detection, which must include cell identification based on the presence of an epithelial marker and the absence of blood cell markers as well as a marker for donor bone marrow origin. In order for these studies to be rigorous, they must also use approaches to rule out cell overlap by microscopy or single-cell isolation. Once these stringent criteria for identification of marrow-derived epithelial cells are used universally, then the field can move forward to address the critical questions about which bone marrow-derived cells are responsible for engraftment as epithelial cells, the mechanisms by which this occurs, whether these cells play a role in normal tissue repair, and whether specific cell subsets can be used for therapeutic benefit.

Abstract
OBJECTIVE For continuous regeneration of human endometrium in menstrual cycles, endometrial stem cells are assumed to supply differentiating endometrial glandular cells. To elucidate the origin of endometrial stem cells, we examined the presence of donor-derived cells in endometria from patients who received bone marrow transplantation from male donors. STUDY DESIGN Endometrial specimens biopsied after hormone replacement therapy were obtained and examined using fluorescent in situ hybridization analysis targeting X or Y chromosomes. RESULTS All recipients had donor-derived Y chromosome-positive endometrial cells, accounting for 0.6-8.4% of glandular epithelial cells and 8.2-9.8% of stromal cells. Most of the endometrial glands were chimeric, consisting of both donor-derived and recipient cells. CONCLUSION Donor-derived cells are capable of composing endometrium in recipients, even those of the opposite sex. These results suggest unexpected plasticity of bone marrow stem cells as well as a potential origin of endometrial stem cells.

Abstract
The cause of metastasis remains elusive despite vast information on cancer cells. We posit that cancer cell fusion with macrophages or other migratory bone marrow-derived cells (BMDCs) provides an explanation. BMDCs fused with tumor cells were present in animal tumor xenografts where they were associated with metastases. In myeloma patients, transcriptionally active myeloma nuclei were incorporated into osteoclasts through fusion. In patients with renal cell carcinoma arising poststem cell transplant, donor genes were incorporated in recipient cancer cell nuclei, most likely through fusion, and showed tumor distribution patterns characteristic of cancer stem cells. Melanoma-macrophage hybrids generated in vitro contained chromosomes from both parental partners, showed increased ploidy, and transcribed and translated genes from both parents. They exhibited chemotactic migration in vitro toward fibronectin and exhibited high frequencies of metastasis when implanted in mice. They produced macromolecules that are characteristic of macrophages and known indicators of metastasis (c-Met, SPARC, MCR1, GnT-V, and the integrin subunits alpha(3), alpha(5), alpha(6), alpha(v), beta(1), beta(3)). They also produced high levels of beta1,6-branched oligosaccharides-predictors of poor survival in patients with melanoma or carcinomas of the breast, lung, and colon. We thus hypothesize that such gene expression patterns in cancer are generated through fusion. Tumor hybrids also showed active autophagy, a characteristic of both metastatic cancers and macrophages. BMDC-tumor cell fusion explains epidermal-mesenchymal transition in cancer since BMDCs express mesodermal traits and epithelial-mesenchymal transition regulators (Twist, SPARC, and others). If BMDC-tumor cell fusion underlies invasion and metastasis in human cancer, new approaches for therapeutic intervention would be mandated.

Abstract
UNLABELLED A large portion of hepatocytes are polyploid cells, thought to arise through endoduplication followed by aborted cytokinesis. However, several recent reports describing liver cell fusion with exogenously derived bone marrow cells have been published. The exact significance of this finding is unclear, because the adopted protocols involve ablation regimens, damaged livers and artificial injections of adult cells. By creating chimeric mice bearing distinct reporter genes (LacZ and GFP), we show that in an unperturbed setting, hepatocytes carrying both markers can be detected via immunohistochemistry and polymerase chain reaction analysis. To further corroborate these findings with a direct visualization of the chromosome content at the single-cell level, we performed genotype analysis via fluorescence in situ hybridization on XY/XX chimeric mice with a Y chromosome-specific paint and an X chromosome-specific bacterial artificial chromosome clone probes. CONCLUSION This technique confirmed the occurrence of cell fusion in adult mouse liver.

Abstract
Pulmonary arterial hypertension (PAH) is a fatal disease associated with severe remodeling of the large and small pulmonary arteries. Increased accumulation of inflammatory cells and apoptosis-resistant cells are contributing factors. Proliferative apoptosis-resistant cells expressing CD133 are increased in the circulation of PAH patients. Circulating cells can contribute to tissue repair via cell fusion and heterokaryon formation. We therefore hypothesized that in the presence of increased leukocytes and CD133-positive (CD133(pos)) cells in PAH lung tissue, cell fusion and resulting genomic instability could account for abnormal cell proliferation and the genesis of vascular lesions. We performed analyses of CD45/CD133 localization, cell fusion, and proliferation during late-stage PAH in human lung tissue from control subjects and subjects with idiopathic (IPAH) and familial (FPAH) PAH. Localization, proliferation, and quantitation of cell populations in individual patients were performed by immunolocalization. The occurrence of cellular fusion in vascular lesions was analyzed in lung tissue by fluorescence in situ hybridization. We found the accumulation of CD45(pos) leukocytic cells in the tissue parenchyma and perivascular regions in PAH patients and less frequently observed myeloid cells (CD45/CD11b). CD133(pos) cells were detected in occlusive lesions and perivascular areas in those with PAH and were more numerous in those with IPAH lesions than in FPAH lesions. Cells coexpressing CD133 and smooth muscle alpha-actin were occasionally observed in occlusive lesions and perivascular areas. Proliferating cells were more prominent in IPAH lesions and colocalized with CD45 or CD133. We found no evidence of increased ploidy to suggest cell fusion. Taken together, these data suggest that abnormal lesion formation in PAH occurs in the absence of cell fusion.

Abstract
Bone marrow-derived cells can take on the phenotype of epithelial cells and express epithelial-specific genes in multiple organs. Here, we focus on recent data on the appearance of marrow-derived epithelial cells in the adult lung. These findings have garnered significant skepticism because in most cases marrow-derived epithelial cells are very rare, the marrow cell of origin is not known, the techniques for detection have needed improvement, and there seem to be multiple mechanisms by which this occurs. Recent studies have focused on these concerns. Once these important concerns are addressed, further studies on the function(s) of these cells will need to be performed to determine whether this engraftment has any clinical significance-either beneficial or detrimental.

Abstract
Although it has been many years since publication of the first peer-reviewed studies showing that bone marrow (BM)-derived cells can become mature-appearing epithelial cells, we still know very little regarding the mechanisms, kinetics, cells, and potential clinical utility or pathology associated with this phenomenon. The initial discovery of BM-derived epithelial cells (BMDE) in the liver was published by Petersen and colleagues (Petersen BE, Bowen WC, Patrene KD, Mars WM, Sullivan AK, Murase N, Boggs SS, Greenberger JS, Goff JP. Bone marrow as a potential source of hepatic oval cells. Science 1999;284:1168-1170). Since that time, BMDE were identified in the skin, eye, GI tract, kidney, and the lung. Surprisingly, once several laboratories started to examine the effects of BM cells after tissue injury, BM-derived cells of different types were found to decrease tissue injury and enhance tissue repair, often without engraftment of marrow-derived epithelial cells. Thus, the potentially beneficial effects of BM-derived cells in some tissue microenvironments may be unrelated to differentiation into nonhematopoietic cell types. Here, I focus on recent findings from my laboratory as well as several other laboratories on the effects of BM cells on lung damage, and BMDE in the lung, including tracheal epithelial cells, bronchiolar epithelial cells, and type II pneumocytes in the alveoli. Potential mechanisms underlying the appearance of marrow-derived epithelial cells, and the role of tissue damage are discussed.

Abstract
The potential bone marrow origin of hepatocytes, cholangiocytes, and ductal progenitor cells in the liver was examined in female mice after transplantation of bone marrow cells from male green fluorescent protein (GFP) transgenic donors. Following stable hematopoietic engraftment, the livers of the recipients were injured with carbon tetrachloride (CCl(4), with or without local irradiation of the liver) or 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC, with or without local irradiation of the liver). The presence of numerous marrow-derived, GFP-positive inflammatory cells had the potential to lead to erroneous interpretation of marrow-derived hepatocytes, cholangiocytes, and ductal progenitor cells. Identification of marrow-derived ductal progenitor or cholangiocyte phenotype using colocalization of GFP or Y chromosome with pancytokeratin staining also failed to distinguish epithelial cells from closely apposed inflammatory cells. To address this inadequacy, we developed a rigorous new immunofluorescence protocol to identify marrow-derived epithelial cells in the liver using Y chromosome (donor marker) and hepatocyte nuclear factor-1 (HNF1, a nuclear marker of liver epithelial, nonhematopoietic phenotype). Using the Y/HNF1 method, rare (approximately one in 20,000) hepatocytes in female mice transplanted with male bone marrow contained a donor-derived Y chromosome. On the other hand, no Y chromosomes were found in cholangiocytes or ductal progenitor cells in mice with liver injury due to DDC or CCl(4). The use of a nuclear marker of mature hepatocytes or cholangiocytes, such as HNF1, improves discrimination of marrow-derived epithelial cells in tissue sections.

The causes of metastasis remain elusive despite vast information on cancer cells. We posit that cancer cell fusion with macrophages or other migratory bone marrow-derived cells (BMDCs) provides an explanation. BMDC-tumour hybrids have been detected in numerous animal models and recently in human cancer. Molecular studies indicate that gene expression in such hybrids reflects a metastatic phenotype. Should BMDC-tumour fusion be found to underlie invasion and metastasis in human cancer, new approaches for therapy would surely follow.

Abstract
Transplanted bone marrow-derived cells (BMDCs) have been reported to fuse with cells of diverse tissues, but the extremely low frequency of fusion has led to the view that such events are biologically insignificant. Nonetheless, in mice with a lethal recessive liver disease (tyrosinaemia), transplantation of wild-type BMDCs restored liver function by cell fusion and prevented death, indicating that cell fusion can have beneficial effects. Here we report that chronic inflammation resulting from severe dermatitis or autoimmune encephalitis leads to robust fusion of BMDCs with Purkinje neurons and formation of hundreds of binucleate heterokaryons per cerebellum, a 10-100-fold higher frequency than previously reported. Single haematopoietic stem-cell transplants showed that the fusogenic cell is from the haematopoietic lineage and parabiosis experiments revealed that fusion can occur without irradiation. Transplantation of rat bone marrow into mice led to activation of dormant rat Purkinje neuron-specific genes in BMDC nuclei after fusion with mouse Purkinje neurons, consistent with nuclear reprogramming. The precise neurological role of these heterokaryons awaits elucidation, but their frequency in brain after inflammation is clearly much higher than previously appreciated.

Abstract
This review will critically evaluate recent findings suggesting that embryonic stem cells and stem cells derived from adult tissues, including bone marrow and umbilical cord blood, may be utilized in repair and regeneration of injured or diseased lungs. This is an exciting and rapidly moving field that holds promise as a novel therapeutic approach for cystic fibrosis and other lung diseases. However, while early studies suggested substantial lung remodeling, particularly with bone marrow-derived cells, more recent findings suggest that engraftment of adult marrow-derived cells in lung is a rare event of uncertain significance. Most recently, it has been suggested that a more relevant role of adult marrow-derived stem cells in lung is modulation of local inflammatory and immune responses. This review will also describe recent advances in understanding of local stem and progenitor cells in lung and their roles in lung development and repair.

Abstract
The lung is a relatively quiescent tissue comprised of infrequently proliferating epithelial, endothelial, and interstitial cell populations. No classical stem cell hierarchy has yet been described for the maintenance of this essential tissue; however, after injury, a number of lung cell types are able to proliferate and reconstitute the lung epithelium. Differentiated mature epithelial cells and newly recognized local epithelial progenitors residing in specialized niches may participate in this repair process. This review summarizes recent discoveries and controversies, in the field of stem cell biology, that are not only challenging, but also advancing an understanding of lung injury and repair. Evidence supporting a role for the numerous cell types believed to contribute to lung epithelial homeostasis is reviewed, and initial studies employing cell-based therapies for lung disease are presented. As a detailed understanding of stem cell biology, lung development, lineage commitment, and epithelial differentiation emerges, an ability to modulate lung injury and repair is likely to follow.
