The intragraft vascularized bone marrow component plays a critical role in tolerance induction after reconstructive transplantation. Cell Mol Immunol 2019; 18:363-373. [PMID: 31754236 DOI: 10.1038/s41423-019-0325-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Accepted: 10/20/2019] [Indexed: 11/08/2022] Open
Abstract
The role of the vascularized bone marrow component as a continuous source of donor-derived hematopoietic stem cells that facilitate tolerance induction of vascularized composite allografts is not completely understood. In this study, vascularized composite tissue allograft transplantation outcomes between recipients receiving either conventional bone marrow transplantation (CBMT) or vascularized bone marrow (VBM) transplantation from Balb/c (H2d) to C57BL/6 (H2b) mice were compared. Either high- or low-dose CBMT (1.5 × 108 or 3 × 107 bone marrow cells, respectively) was applied. In addition, recipients were treated with costimulation blockade (1 mg anti-CD154 and 0.5 mg CTLA4Ig on postoperative days 0 and 2, respectively) and short-term rapamycin (3 mg/kg/day for the first posttransplant week and then every other day for another 3 weeks). Similar to high-dose conventional bone marrow transplantation, 5/6 animals in the vascularized bone marrow group demonstrated long-term allograft survival (>120 days). In contrast, significantly shorter median survival was noted in the low-dose CBMT group (~64 days). Consistently high chimerism levels were observed in the VBM transplantation group. Notably, low levels of circulating CD4+ and CD8+ T cells and a higher ratio of Treg to Teff cells were maintained in VBM transplantation and high-dose CBMT recipients (>30 days) but not in low-dose VBM transplant recipients. Donor-specific hyporesponsiveness was shown in tolerant recipients in vitro. Removal of the vascularized bone marrow component after secondary donor-specific skin transplantation did not affect either primary allograft or secondary skin graft survival.

Abstract
BACKGROUND Successful nerve regeneration is critical to the functional success of composite tissue allografts. The present study was designed to characterize the effect of acute rejection on nerve regeneration and functional recovery in the setting of orthotopic limb transplantation. METHODS A rat orthotopic limb transplantation model was used to evaluate the effects of acute rejection on nerve regeneration and motor recovery. Continuous administration of FK506 (full suppression), administration of FK506 for the first 8 of 12 weeks (late rejection), or delayed administration of FK506/dexamethasone following noticeable rejection (early rejection) was used to preclude or induce rejection following limb transplantation. Twelve weeks postoperatively, nerve regeneration was assessed by means of histomorphometric analysis of explanted sciatic nerve, and motor recovery was assessed by means of evoked muscle force measurement in extensor digitorum longus muscle. RESULTS A single episode of acute rejection that occurs immediately or late after reconstruction does not significantly alter the number of regenerating axonal fibers. Acute rejection occurring late after reconstruction adversely affects extensor digitorum longus muscle function in composite tissue allografts. CONCLUSIONS Collected data reinforce that adequate immunosuppressant administration in cases of allogeneic limb transplantation ensures levels of nerve regeneration and motor functional recovery equivalent to that of syngeneic transplants. Prompt rescue following acute rejection was further demonstrated not to significantly affect nerve regeneration and functional recovery postoperatively. However, instances of acute rejection that occur late after reconstruction affect graft function. In total, the present study begins to characterize the effect of immunosuppression regimens on nerve regeneration and motor recovery in the setting of composite tissue allografts.

Abstract
The preclinical experimental models of vascularized composite allografts (VCAs) have been rapidly developed for the assessment of immunomodulatory protocols for clinical application. Recently, researchers have focused on immunomodulatory protocols which overcome the immunologic barrier between the allogeneic donor and recipient and may lead to tolerance induction. In order to test the feasibility of chimerism induction, experimental VCAs have been performed in different models including rodents, large animals, and nonhuman primates. These models differ in the complexity of transplanted tissue and in their responses to immunomodulatory protocols. In most applications, VCA contains multiple-tissue components; however, each individual component of CTA possesses unique immunologic characteristics that ultimately contribute to the chimerism induction and successful outcome of the VCA. Heterogenic character and complexity of tissue components in different VCA models determine the quality and robustness of donor-specific chimerism. As introduced in experimental studies, variable immunomodulatory options have been studied to achieve tolerance to VCA in rodents and large animal models allowing for widespread application in clinic. In this paper, based on our own experience, we have analyzed the current knowledge of tolerance-inducing strategies via chimerism induction in VCA experimental models in the context of immunomodulatory protocols and VCA complexity and their relevance and applicability to clinical practice.

Abstract
Successful hand and face transplantation in the last decade has firmly established the field of vascularized composite allotransplantation (VCA). The experience in VCA has thus far been very similar to solid organ transplantation in terms of the morbidity associated with long-term immunosuppression. The unique immunological features of VCA such as split tolerance and resistance to chronic rejection are being investigated. Simultaneously there has been laboratory work studying tolerogenic protocols in animal VCA models. In order to optimize VCA outcomes, translational studies are needed to develop less toxic immunosuppression and possibly achieve donor-specific tolerance. This article reviews the immunology, animal models, mixed chimerism & tolerance induction in VCA and the direction of future research to enable better understanding and wider application of VCA.

Abstract
The aim of the study was to follow the development of microchimerism after allogeneic vascularized bone marrow transplantation (VBMT) versus conventional bone marrow transplantation (BMT). In one group, a VBMT model consisted of donor Brown Norway rat hind limb heterotopic transplanted on recipient Lewis rats. An intravenous infusion of donor bone marrow cells in suspension equivalent to that grafted in the vascularized femur limb was administered intravenously to recipient rats in the second group. Cellular microchimerism was investigated in recipients of VBMT versus BMT. Donor-derived cells could be detected in VBMT recipients at 30 and 60 days but not in recipients of intravenous suspension of BMC. VBMT provides a theoretical alternative to conventional cellular bone marrow transplantation by addressing crucial clinical problems such as failure of engraftment or graft-versus-host disease.

Abstract
Composite tissue allotransplantation (CTA) transplantation is currently being performed with increasing frequency in the clinic. The feasibility of the procedure has been confirmed in over 40 successful hand transplants, 3 facial reconstructions, and vascularized knee, esophageal, abdominal wall, and tracheal allografts. The toxicity of chronic, nonspecific immunosuppression remains a major limitation to the widespread availability of CTA and is associated with opportunistic infections, nephrotoxicity, end-organ damage, and an increased rate of malignancy. Methods to reduce or eliminate the requirement for immunosuppression would represent a significant step forward in the field. Mixed chimerism induces tolerance to solid organ and tissue allografts, including CTA. This overview focuses on the history and expanding applications of CTA as a new frontier in transplantation, and considers the important hurdles that must be overcome through research to allow widespread clinical application.

Abstract
Composite tissue allotransplantation (CTA) is emerging as a potential treatment for complex tissue defects. It is currently being performed with increasing frequency in the clinic. The feasibility of the procedure has been confirmed through 30 hand transplantation, 3 facial reconstructions, and vascularized knee, esophageal, and tracheal allografts. A major drawback for CTA is the requirement for lifelong immunosuppression. The toxicity of these agents has limited the widespread application of CTA. Methods to reduce or eliminate the requirement for immunosuppression and promote CTA acceptance would represent a significant step forward in the field. Multiple studies suggest that mixed chimerism established by bone marrow transplantation promotes tolerance resulting in allograft acceptance. This overview focuses on the history and the exponentially expanding applications of the new frontier in CTA transplantation: immunology associated with CTA; preclinical animal models of CTA; clinical experience with CTA; and advances in mixed chimerism-induced tolerance in CTA. Additionally, some important hurdles that must be overcome in using bone marrow chimerism to induce tolerance to CTA are also discussed.

Abstract
Composite tissue allotransplantation holds a great potential for providing increased knowledge of anatomy and microsurgical experience for life-enhancing reconstructions. Many transplant cases around the world have made this a clinical reality at the present time. Composite tissue allotransplants contain multiple tissue types, including bone, muscle, vessels, nerves, skin, and immune cells and bear a huge antigenic load. Although immunosuppressive drugs are applied successfully to prevent allograft rejection, their side effects pose a barrier to worldwide use. Bone marrow therapy in many tolerance induction protocols, therefore, provides a guide to reaching the target of permanent immunotolerance. Multiple studies suggest that bone marrow is immunomodulatory and may facilitate allograft acceptance. In this review, bone marrow based therapy protocols of clinical and experimental models are presented in two major categories: solid organ and composite tissue transplantation.

Abstract
Administration of donor bone marrow (BM) cells can improve the outcome of transplantation. The ability of donor vascularized bone marrow transplantation (VBM) to provide an ongoing source of donor cells and improve survival in a rigorous rat model of hind limb transplantation (HLTX) was investigated. HLTX were performed between Brown Norway (BN) donors and Lewis recipients in three groups: HLTX; HLTX plus intravenous donor BM cells and HLTX plus simultaneous VBM transplantation. Animals received 12 weeks triple immunosuppression. Survival was compared at 4 months and donor chimerism was evaluated. Simultaneous VBM transplantation led to slight but nonsignificant prolongation of survival (P=0.056). Donor cells in the VBM were eventually replaced by recipient and there was no long-term increase in chimerism. Few donor cells were observed in thymus. Simultaneous VBM transplantation showed a trend for improved survival of HLTX however the VBM failed to provide a sustained increase in chimerism.

Abstract
In this review, we examine the applicability of the vascularized bone marrow transplant (VBMT) as an alternative to conventional bone marrow transplantation (BMT). As a new surgical approach, the VBMT is unique by transplantation of the stromal environment that eliminates the need for an engraftment period, provides critical signaling and modulatory functions, and may potentiate tolerance induction. Thus far, VBMT studies have demonstrated an absence of graft-versus-host disease (GVHD) and robust engraftment into nonmanipulated as well as irradiated recipients with evidence of immunological tolerance. Further investigation is needed to determine the applicability of VBMT as an alternative to BMT.

Abstract
BACKGROUND In this study, we evaluated the role of host thymus in tolerance induction in composite tissue allografts (CTA) across major histocompatibility complex (MHC) barrier during a 7-day alphabeta- T-cell receptor (TCR)/ cyclosporine A (CsA) protocol. MATERIALS AND METHODS A total of 62 limb allograft transplants were studied. Euthymic (group A) and thymectomized (group B) Lewis recipients (LEW, RT1(1)) received vascularized hind-limb allografts from hybrid Lewis x Brown-Norway (F1), (LBN, RT1(1+n)) donors. Mixed lymphocyte reaction (MLR) and skin grafting assessed donor-specific tolerance in vitro and in vivo, respectively. Flow cytometry determined the efficacy of immunosuppressive protocols and the presence of donor-specific chimerism. Immunocytochemistry revealed the presence of donor-specific cells in the lymphoid organs of recipients. RESULTS Isograft transplants survived indefinitely. For thymectomized rats, the median survival time (MST) of limb allograft in non-treated recipients was 7 days; monotherapy with alphabeta-TCR extended MST to 16 days, and CsA therapy extended it to 30 days. Using the alphabeta-TCR/CsA protocol, the MST of allografts was 51 days. For euthymic rats, the MST of limb allograft in non-treated recipients was 7 days; monotherapy with alphabeta-TCR or CsA extended MST to 13 or 22 days, respectively. Treatment with alphabeta-TCR/CsA resulted in indefinite allografts survival (MST=370 days). MLR and skin grafting confirmed donor-specific tolerance in euthymic recipients. Flow cytometry showed stable chimerism in the euthymic rats and transient chimerism in thymectomized limb recipients. Immunoperoxidase staining revealed the persistence of donor-derived cells in the lymphoid tissues of euthymic recipients. CONCLUSION We found that the presence of thymus was imperative for the induction of donor-specific tolerance in rat hind-limb composite tissue allografts using a alphabeta-TCR/CsA protocol.

Abstract
Tolerance induction through allogeneic bone marrow transplantation is an alternative method to chronic immunosuppression in maintaining long-term allograft survival. In this article, we introduce a new method of bone marrow allotransplantation, which preserves its natural microenvironment and does not require marrow processing or recipient conditioning. A total of 43 skin graft transplantations were performed in nine experimental groups between isogeneic [Lewis to Lewis (LEW, RT1(1))] and allogeneic [Lewis x Brown Norway (LBN --> F1, RT1(1+n)) to Lewis] rats under 35-day protocol of alphabeta T-cell receptor (TCR) monoclonal antibody (mAb) and cyclosporine (CsA) protocol. Monotherapies combined with "crude" bone marrow transplantation resulted in extended survival up to 21 days under CsA and up to 10 days under alphabeta-TCR mAb protocol. The use of combined protocol of alphabeta-TCRmAb/CsA with crude bone marrow transplantation resulted in the extension of skin allograft survival up to 65 days (P < .05). This new simple method of "crude" bone marrow allotransplantation without recipient conditioning is a promising, minimally invasive technique with a potential for direct clinical application.

Abstract
According to our experience of over 100 hindlimb transplantations, in rats, catching the posterior wall with an anterior wall suture is the most common cause of thrombosis and acute transplant failure. It is generally due to inadequate visibility of the lumen and consequent blind suture placement. With an intention to find a superior suture technique, a comparative study between standard end-to-end interrupted and combined continuous sutures and interrupted tie techniques was performed. Twenty hindlimb transplantations to rats' femoral vessels were performed in each group. Anastomosis time, patency, complications, and animal and transplant survivals were compared. In the interrupted suture group (group I), anastomosis failure was encountered in one vein, with 95% of immediate patency rate. A redo of the venous anastomosis was performed and successful. The combined suture technique (group II) had 100% patency rates without complications. The average time for arterial anastomosis in groups I and II was 8.5 and 8.9 min, and for venous anastomosis, 10.7 and 9.6 min, respectively. At 2 weeks, no differences were found between groups as related to transplant and animal survival.

Abstract
Relatively slow hematopoietic recovery after isolated bone marrow (I-BM) engraftment is probably caused by a disrupted microenvironment of stromal and stem cells. Thus, we compared the kinetics of hematopoietic recovery of lethally irradiated rats that received I-BM versus vascularized BM (V-BM). Total body irradiated (TBI; 8 Gy) Lewis (LEW; RT1(1)) rats were either injected IV with syngeneic sex-mismatched 80 x 10(6) I-BM or transplanted with 80 x 10(6) V-BM in orthotopic hind limb grafts. Ten days later, peripheral blood (PB) and mesenteric lymph nodes (MLN) of these recipients were examined for the presence of donor-derived hematopoietic cells with a panel of monoclonal antibodies by FACS. To detect male cells in sex-mismatched female recipients, PCR was performed using male Y chromosome primers. When examined in PB and MLN, recipients transplanted with V-BM displayed significantly faster recovery of leukocytes (CD43+), monocytes (CD14+), and T cells (CD5+) in comparison with I-BM recipients. In addition, only V-BM (but not I-BM) groups contained stroma-like male-positive cells in PB and MLN. Our results suggest that V-BM transplants provided superior hematopoietic recovery in comparison to I-BM transplants. We postulated that close proximity between stromal and stem cells in V-BM is essential for efficient repopulation with progenitors of different lines of leukocytes.

Abstract
An isolated vascularized bone marrow transplant (iVBMT) model was developed to study the contribution of the bone marrow component in a composite tissue allograft. We hypothesized that the iVBMT would be functional and cause graft-versus-host disease (GVHD) in a fraction of the recipients. Lewis iVBMT grafts were transplanted to Lewis-Brown Norway recipients. Animals were sacrificed at various times from 1 to 14 weeks. Polymerase chain reaction for microchimerism was performed on the host's marrow. No animals exhibited signs of GVHD at death. Histologic examination of the grafts showed a normal mix of hematopoietic and fatty elements and appeared to be functional. Tissues usually affected-tongue, ear, liver, and gut-also showed no evidence of disease. Polymerase chain reaction demonstrated microchimerism in both groups. These findings suggest that the vascularized bone marrow within a composite tissue allograft is not the component that causes GVHD; rather, it may serve an immunomodulatory function for tolerance induction.

Abstract
Progressive renal failure is accompanied by uncontrolled accumulation of extracellular matrix in glomeruli and tubulointerstitium, eventually resulting in glomerulosclerosis. Although glomerulosclerosis occurs secondary to various renal diseases, the fact that not all patients develop progressive glomerulosclerosis suggests that genetic factors may underlie the tendency to progress, or not to progress. Identified were two Lewis rat substrains with small genetic differences but with considerable difference in resolution of glomerulonephritis after anti-Thy-1 administration. In the Lewis/Møllegard rat strain, anti-Thy-1 glomerulonephritis spontaneously resolves within 4 wk. In contrast, Lewis/Maastricht rats develop progressive glomerulosclerosis after induction of this disease. The involvement of bone marrow-derived cells and kidney cells in the development of glomerulosclerosis was determined. In the first study, exchange of bone marrow between these substrains did not affect the course of anti-Thy-1 nephritis. Lewis/Møllegard rats recovered rapidly, but Lewis/Maastricht rats showed progressive disease regardless of the genotype of the bone marrow they received. In the second study, kidneys were exchanged between the substrains. After transplantation, anti-Thy-1 nephritis was induced and glomerular damage assessed at day 21. Severe damage was observed in Lewis/Maastricht glomeruli independent of whether the kidney had been transplanted or not. Similarly, Lewis/Møllegard glomeruli, whether transplanted or not, revealed no residual histopathologic abnormalities. The inherited differences between the two substrains with regard to their insusceptibility to develop progressive glomerulosclerosis after mesangial injury are governed by genes expressed by the kidney, but not by bone marrow-derived cells.

Abstract
An isolated vascularized bone marrow transplant (iVBMT) model was previously developed in the rat to specifically study the role of bone marrow and its environment in a composite tissue allotransplant. An extraperitoneal model was successfully created to avoid laparotomy and cross-clamping of the great vessels. The extraperitoneal iVBMT model consisted of a left donor femur that was harvested with its nutrient vessels, anastomosed to the right femoral vessels in a syngeneic host, and then placed subcutaneously in the abdominal wall. At explant, the graft vessels were grossly patent, and histology of the graft bones showed a viable marrow compartment. Polymerase chain reaction demonstrated peripheral chimerism in the recipients. This model is technically simple with minimal morbidity in the recipient animals. By using the iVBMT, future studies across semiallogeneic and allogeneic barriers will help define the role of the bone marrow compartment in composite tissue allotransplants to potentially induce immune tolerance.

Abstract
BACKGROUND This study assessed the ability of antilymphocyte serum (ALS) and cyclosporine A (CsA) to induce tolerance for hind limb composite tissue allograft in rats without chronic immunosuppression. METHODS Hind limb transplantations were performed in Lewis-Brown-Norway (LBN, RT1(1+n)) and Lewis (LEW, RT1(1)) rats. Treatment consisted of ALS only (0.4 mL/kg), CsA only (16 mg/kg), and a combination of CsA and ALS, and it was administered 12 hr before surgery at three different intervals (7, 14, and 21 days). Long-term survivors were tested for tolerance by standard skin grafting from the recipient (LEW), the donor (LBN), and the third party (ACI, RT1 ) 60 days after cessation of the treatment and by mixed lymphocyte reaction at 100 days. T-cell lines were analyzed with flow cytometry. RESULTS Single use of ALS in all treatment intervals did not prolong allograft survival. Single use of CsA extended survival up to 23 days in the 21-day protocol group. CsA and ALS caused indefinite survival in two of six rats in the 14-day protocol and in all six rats in the 21-day protocol (>420 days). The six long-term survivors in the 21-day protocol accepted the skin grafts from the donor (LBN) and the recipient (LEW) and rejected third-party grafts (ACI). Tolerant animals showed a donor-specific hematopoietic chimerism of 35% to 42% in the peripheral blood. Mixed lymphocyte reaction assay demonstrated tolerance to the host and donor alloantigens and increased response to the third party. CONCLUSIONS Administration of CsA and ALS for 21 days induced donor-specific tolerance in the recipients of the rat hind limb composite tissue allografts. The mechanism of tolerance should be investigated further.

Abstract
This study indicates that circulating progenitors of bone marrow origin give rise to cells with smooth muscle-like properties during formation of neointimal thickenings in the arterial wall after allotransplantation and after balloon injury. A segment of abdominal aorta was transplanted from female F344 to male LEW rats, and the grafts were analyzed for male cells by using the gene as a marker. Immunostaining demonstrated that CD45-positive leukocytes made up 35-45% of the neointimal cells during the 8-week period examined. Concurrently, up to 70% of the neointimal cells were of host origin, as shown by real-time polymerase chain reaction for the gene (Y chromosome). This suggests that the neointima contained host cells also of noninflammatory character. Accordingly, many cells positive for smooth-muscle alpha-actin were detected in this layer. To explore the possible bone marrow origin of allograft cells, female LEW rats were irradiated and substituted with bone marrow from male LEW rats. Subsequently, the animals received an aortic transplant from female F344 rats or were exposed to a balloon injury of the carotid artery. Immunostaining and real-time polymerase chain reaction confirmed the above findings, but the fractions of leukocytes and -positive cells were lower in the carotids than in the allografts. Combined primed in situ labeling and immunostaining verified that not only inflammatory but also smooth muscle-like cells of male origin appeared in the vessel wall in both situations. These observations suggest that the smooth-muscle cells that participate in the development of neointimal lesions during vascular disease may, in part, originate from circulating progenitors.

Abstract
Composite tissue allograft (CTA) transplantation became a clinical reality despite major side effects associated with the administration of chronic immunosuppression. Development of new treatment modalities eliminating life-long immunosuppression is essential for the future of CTA transplantation. In this study, combined use of cyclosporine A (CsA) and antilymphocyte serum (ALS) was tested for the potential to induce tolerance in the rat hind-limb allograft recipients across a major histocompatibility (MHC) barrier (Lewis-Brown-Norway [LBN, RT1(l+n)] to Lewis [LEW, RT1(l)] rats). Thirty transplantations were performed in 5 experimental groups. Animals received CsA and ALS 12 hours before surgery for 21 days thereafter. Although the allograft controls rejected their limbs at day 7 combined treatment of CsA and ALS resulted in indefinite survival (over 420 d) in all allograft recipients. Long-term survivors showed 35% to 42% of donor-specific chimerism in the peripheral blood. Clinical tolerance was confirmed by acceptance of the donor-specific skin grafts and immunocompetence was confirmed by rejection of the third-party grafts. Mixed lymphocyte reaction revealed suppressed response against donor-type antigens and increased response to third-party antigens. Donor-specific tolerance across MHC barrier was induced in CTA allografts under 21 days protocol of ALS/CsA.

Abstract
The clinical transplantation of composite tissue allografts (CTA) such as human hand or larynx is stimulating discussions among surgeons at national and international forums on the indications, ethical aspects, toxic effects of immunosuppression, and functional results of the first reported cases of unilateral and bilateral hand transplantation. This Clinical Perspective article presents the latest advances in clinical and experimental research related to the field of CTAs. The article presents the historic aspects of CTA, a broad view of the current state of composite tissue transplantation, the mechanism of allograft rejection, current experimental and clinical protocols, and, finally, the future prospects of the standard use of CTAs. It is clear that there is a substantial demand for routine use of CTAs but the treatment protocols need to be optimized and the functional outcomes need to be improved.
