Donor derived hematopoietic stem cell niche transplantation facilitates mixed chimerism mediated donor specific tolerance. Front Immunol 2023; 14:1093302.

Abstract
Compelling experimental evidence confirms that the robustness and longevity of mixed chimerism (MC) relies on the persistence and availability of donor-derived hematopoietic stem cell (HSC) niches in recipients. Based on our prior work in rodent vascularized composite allotransplantation (VCA) models, we hypothesize that the vascularized bone components in VCA bearing donor HSC niches, thus may provide a unique biologic opportunity to facilitate stable MC and transplant tolerance. In this study, by utilizing a series of rodent VCA models we demonstrated that donor HSC niches in the vascularized bone facilitate persistent multilineage hematopoietic chimerism in transplant recipients and promote donor-specific tolerance without harsh myeloablation. In addition, the transplanted donor HSC niches in VCA facilitated the donor HSC niches seeding to the recipient bone marrow compartment and contributed to the maintenance and homeostasis of stable MC. Moreover, this study provided evidences that chimeric thymus plays a role in MC-mediated transplant tolerance through a mechanism of thymic central deletion. Mechanistic insights from our study could lead to the use of vascularized donor bone with pre-engrafted HSC niches as a safe, complementary strategy to induce robust and stable MC-mediated tolerance in VCA or solid organ transplantation recipients.

The Positive Impact of Donor Bone Marrow Cells Transplantation into Immunoprivileged Compartments on the Survival of Vascularized Skin Allografts. Arch Immunol Ther Exp (Warsz) 2021; 69:28. [PMID: 34633538 PMCID: PMC8505373 DOI: 10.1007/s00005-021-00631-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Accepted: 08/02/2021] [Indexed: 11/30/2022]
Abstract
Using the vascularized skin allograft (VSA) model, we compared the tolerogenic effects of different allogeneic bone marrow transplantation (BMT) delivery routes into immunoprivileged compartments under a 7-day protocol immunosuppressive therapy. Twenty-eight fully MHC mismatched VSA transplants were performed between ACI (RT1a) donors and Lewis (RT11) recipients in four groups of seven animals each, under a 7-day protocol of alfa/beta TCRmAb/CsA (alpha/beta-TCR monoclonal antibodies/Cyclosporine A therapy). Donor bone marrow cells (BMC) (100 × 106 cells) were injected into three different immunoprivileged compartments: Group 1: Control, without cellular supportive therapy, Group 2: Intracapsular BMT, Group 3: Intragonadal BMT, Group 4: Intrathecal BMT. In Group 2, BMC were transplanted under the kidney capsule. In Group 3, BMC were transplanted into the right testis between tunica albuginea and seminiferous tubules, and in Group 4, cells were injected intrathecally. The assessment included: skin evaluation for signs and grade of rejection and immunohistochemistry for donor cells engraftment into host lymphoid compartments. Donor-specific chimerism for MHC class I (RT1a) antigens and the presence of CD4+/CD25+ T cells were assessed in the peripheral blood of recipients. The most extended allograft survival, 50–78 days, was observed in Group 4 after intrathecal BMT. The T cells CD4+/CD25+ in the peripheral blood were higher after intrathecal BMC injection than other experimental groups at each post-transplant time point. Transplantation of BMC into immunoprivileged compartments delayed rejection of fully mismatched VSA and induction of robust, donor-specific chimerism.

The intragraft vascularized bone marrow component plays a critical role in tolerance induction after reconstructive transplantation. Cell Mol Immunol 2019; 18:363-373.

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
Tolerance induction by means of costimulation blockade has been successfully applied in solid organ transplantation; however, its efficacy in vascularized composite allotransplantation, containing a vascularized bone marrow component and thus a constant source of donor-derived stem cells, remains poorly explored. In this study, osteomyocutaneous allografts (alloOMCs) from Balb/c (H2(d) ) mice were transplanted into C57BL/6 (H2(b) ) recipients. Immunosuppression consisted of 1 mg anti-CD154 on day 0, 0.5 mg CTLA4Ig on day 2 and rapamycin (RPM; 3 mg/kg per day from days 0-7, then every other day for 3 weeks). Long-term allograft survival, donor-specific tolerance and donor-recipient cell trafficking were evaluated. Treatment with costimulation blockade plus RPM resulted in long-term graft survival (>120 days) of alloOMC in 12 of 15 recipients compared with untreated controls (median survival time [MST] ≈10.2 ± 0.8 days), RPM alone (MST ≈33 ± 5.5 days) and costimulation blockade alone (MST ≈45.8 ± 7.1 days). Donor-specific hyporesponsiveness in recipients with viable grafts was demonstrated in vitro. Evidence of donor-specific tolerance was further assessed in vivo by secondary donor-specific skin graft survival and third-party graft rejection. A significant increase of Foxp3(+) regulatory T cells was evident in tolerant animals. Donor cells populated peripheral blood, thymus, and both donor and recipient bone marrow. Consequently, combined anti-CD154/CTLA4Ig costimulation blockade-based therapy induces donor-specific tolerance in a stringent murine alloOMC transplant model.

Abstract
BACKGROUND Limb transplantation is emerging as a promising area of surgery and is an indispensable alternative for prosthetic rehabilitation of amputees, the severity of which is increasing because of combat-related injuries. Successful unilateral and bilateral limb transplantations have already been performed before this operation. METHODS We performed the first ever quadruple limb transplantation in February 2012. The limbs procured from a 40-year-old man heart-beating donor were transplanted to a 27-year-old male patient who was a quadruple amputee for the last 14 years because of an electrical injury. RESULTS To shorten the ischemic period to a minimum, 3 separate microsurgery teams worked simultaneously. All extremities were reperfused within 8 hours of procurement, and the operation lasted for 12 hours. Metabolic load was managed by hemodialysis. One hour after the completion of the operation, cardiac arrest developed, resuscitation of which necessitated median sternotomy and temporary partial cardiopulmonary support. Despite the removal of the transplanted limbs and all efforts including continuous hemodialysis, plasmapheresis, and extracorporeal membrane oxygenation, the patient died on the fourth day after transplantation in a clinical condition of severe systemic inflammation. CONCLUSIONS The problems we faced were difficulty of vascular access for invasive monitoring and fluid replacement, and the severe systemic inflammation effects of which could not be dealt with, despite aggressive supportive treatment. We hope that our experience will enlighten the surgeons who are willing to extend the limits of limb transplantation and serve the success of future operations.

Abstract
INTRODUCTION Vascularized composite allotransplantation (VCA), a new reconstructive option for patients suffering from extensive facial defects leads to superior functional and aesthetic outcomes compared to the standard autologous reconstruction. Among VCA recipients, each case involves different facial structures and tissues depending on the patient's injury, thus drawing conclusions on the mechanism of immune interactions between the donor and recipient is challenging. This study introduces a new total hemiface VCA model, including scalp, external ear, mystacial pad, premaxilla, upper/lower lids, nose, and upper/lower lips to evaluate the effect of transplantation of multitissue VCA on the recipient's immune response. MATERIAL AND METHODS Ten hemiface allotransplantations were performed in two groups between Lewis-Lewis (isograft) and LBN-Lewis (allograft) rats. Cyclosporine A (CsA) monotherapy was applied in the allograft group to prevent rejection. RESULTS All flaps survived up to 100 days post-transplant. The mean warm ischemia time was 45 minutes. Histological analysis revealed normal bone, cartilage (ear and nose), conjunctiva, palpebra, and eyelashes. Flow cytometry confirmed donor-specific chimerism for T cells (CD4/RT1(n) and CD8/RT1(n)) and B cells (CD45RA/RT1(n)) in the peripheral blood of all rats in the allotransplantation group. At post-transplant day 7, chimerism levels were at 1.68% for CD4/RT1(n) , 0.46% for CD8/RT1(n) and 0.64% for CD45RA/RT1(n). However, chimerism levels for CD4/RT1(n), CD8/RT1(n), and CD45RA/RT1(n) populations decreased at long-term follow-up (at post-transplant day 100) to 0.08%, 0.04%, and 0.23%, respectively. CONCLUSION The feasibility and long-term survival of the new hemiface VCA transplantation model was confirmed, donor-specific chimerism and post-transplant tissue changes were evaluated.

Abstract
In this report, we present a rat orthotopic forelimb allotransplantation model. Eight forelimbs were transplanted from Brown Norway rats to Lewis rats. Axillary vessels of transplant were used as the vascular pedicles, which were anastomosed to the external jugular vein and common carotid artery of the recipient rat. The ulnar, radial, and median nerves were also repaired. Among rats, a tapered dose of cyclosporine was administered in five rats. In other three rats, no immunosuppressive therapy was given. The viability and signs of rejection of transplanted forelimbs, sensation recovery, bone healing, and histology were assessed up to the 90th postoperative day. All of rats but one survived surgery. All of transplanted forelimbs survived. In the rats treated with cyclosporine the transplanted forelimbs achieved long-term survival with motion and sensation recovery. On 90th day after surgery, bone healing was achieved. There was no sign of rejection in histology. In the rats without cyclosporine treatment, the transplanted forelimbs experienced tissue necrosis started from day 12 postoperatively. This experimental study showed the feasibility of orthotopic forelimb allotransplantation in the rat model. © 2015 Wiley Periodicals, Inc. Microsurgery 36:672-675, 2016.

Abstract
BACKGROUND Finger allotransplantation is a promising treatment for severe finger destruction. However, more research is required to decrease the risks of this procedure to a level at which the clinical use of this non-life-saving procedure is justified. A proper animal model is essential for the required experiments. METHODS In this article, we established a toe transplantation model based on anatomic studies. A tapered dose of Cyclosporine A (CsA) was used as an immunosuppressive therapy in the Brown Norway-to-Lewis allotransplantation experimental group, whereas isotransplantation or allotransplantation without treatment or with ligated pedicles was performed on the control groups. Recipients were assessed daily after operation for any signs of rejection and complications. On postoperative day 90, skin graft test was used to test the level of donor-specific tolerance in the recipients. On postoperative day 120, x-rays and micro-computed tomographies were performed for bone morphology evaluation. The chimerism in the recipient peripheral blood, lymph node, spleen, and thymus was tested by flow cytometry and immunohistochemical staining. And histologic study of the toe grafts and skin grafts were carried out. RESULTS The blood supply of the toe graft was confirmed, and accordingly, transplantations were performed. The isografts survived indefinitely. The allografts with ligated pedicles experienced necrosis within 5 d. The allografts without treatment exhibited necrosis within 14 d. Forty percent, 20%, and 40% of the allografts associated with the CsA treatment experienced severe rejection, mild rejection, and nonrejection, according to gross graft appearance, respectively. Skin grafting tests showed three different types of results. X-rays and micro-computed tomographies reveal nearly normal bone morphologies in the bone structures of all surviving animals with grafts. Low levels of donor-specific chimerism were detected in the peripheral blood samples. Spleen, lymph node, and thymus chimerism were also confirmed in the long-term surviving animals with allografts. Histologic evaluation of the long-term survivals revealed similar graft morphologies in the isografts and the nonrejected allografts, inflammatory cell infiltration in the mildly rejected allografts, and degraded cutaneous appendages in the severely rejected allografts. CONCLUSIONS We established a toe allotransplantation model. Moreover, the low rate of chimerism did not introduce specific tolerance, which might explain the high rejection rate. This model might facilitate future research in finger allotransplantation.

Chimerism-based experimental models for tolerance induction in vascularized composite allografts: Cleveland clinic research experience. Clin Dev Immunol 2013; 2013:831410. [PMID: 23573114 PMCID: PMC3612438 DOI: 10.1155/2013/831410] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2012] [Revised: 02/12/2013] [Accepted: 02/12/2013] [Indexed: 11/20/2022]
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
In the past 50 years, hand surgeons have made considerable contributions to microsurgery. The unique demands of complex upper extremity care have driven many of the technical and scientific advances of this discipline, including functional muscle transfers, nerve transfers, and composite tissue allotransplantation. The purpose of this article was to review the current applications of microsurgery to the upper extremity.

Abstract
Recent advances in transplant immunology are shifting the focus from immunosuppression to immunoregulation, making composite tissue allotransplantation with novel and less potent immunosuppressive regimens a possibility. Hand transplantation has been the most frequently performed human composite tissue allotransplantation, with more than 50 upper extremity-based transplants done worldwide. Further research is needed regarding immunomodulating protocols, and careful oversight and individualized screening procedures will be required as patients seeking improved quality of life through human composite tissue allotransplantation come to accept a certain level of risk in these experimental procedures. Still, composite tissue allotransplantation offers to advance transplant medicine and reconstructive surgery.

Abstract
In this study, we extended application of face transplantation model in rat by incorporation of vascularized premaxilla, and nose with infraorbital and facial nerves for evaluation of allotransplanted sensory and motor nerve functional recovery. In group I (n = 3) the dissection technique is studied. In group II (n = 5) isotransplantations were performed. In group III (n = 5) allotransplantations were performed under Cyclosporin A monotherapy. Grafts; composed of nose, lower lip, and premaxilla; were dissected. Infraorbital nerve and facial nerve were included into the transplant. A heterotopic transplantation was performed to inguinal region of recipient. Nerve coaptations were performed between infraorbital-sapheneous nerve and facial-femoral nerve. CT scan, somatosensory-evoked potential testing (SSEP), motor-evoked potential testing (MEP), and microangiography were used for evaluation. All transplants survived indefinitely over 100 days. Microangiography showed preserved vascularization of the graft. Computed tomography revealed vital premaxillary bone segments. SSEP and MEP confirmed recovery of motor and sensory functions and latencies reached 67% of normal infraorbital nerve value and 70% of normal facial nerve value at 100 days post-transplant. We have introduced new midface transplant model of composite midface allograft with sensory and motor units. In this model, motor and sensory functional recovery was confirmed at 100 days post-transplant.
