Abstract
Hair loss is a debilitating condition associated with the depletion of dermal papilla cells (DPCs), which can be replenished by dermal sheath cells (DSCs). Hence, strategies aimed at increasing the populations of DPCs and DSCs hold promise for the treatment of hair loss. In this study, we demonstrated in mice that introduced exogenous DPCs and DSCs (hair follicle mesenchymal stem cells) could effectively migrate and integrate into the dermal papilla and dermal sheath niches, leading to enhanced hair growth and prolonged anagen phases. However, the homing rates of DPCs and DSCs were influenced by various factors, including recipient mouse depilation, cell passage number, cell dose, and immune rejection. Through in vitro and in vivo experiments, we also discovered that the CXCL13/CXCR5 pathway mediated the homing of DPCs and DSCs into hair follicle niches. This study underscores the potential of cell-based therapies for hair loss by targeted delivery of DPCs and DSCs to their respective niches and sheds light on the intriguing concept that isolated mesenchymal stem cells can home back to their original niche microenvironment.

Abstract
Mouse models are an essential tool in different areas of research, including nutrition and phytochemical research. Traditional inbred mouse models have allowed the discovery of therapeutical targets and mechanisms of action and expanded our knowledge of health and disease. However, these models lack the genetic variability typically found in human populations, which hinders the translatability of the results found in mice to humans. The development of genetically diverse mouse models, such as the collaborative cross (CC) or the diversity outbred (DO) models, has been a useful tool to overcome this obstacle in many fields, such as cancer, immunology and toxicology. However, these tools have not yet been widely adopted in the field of phytochemical research. As demonstrated in other disciplines, use of CC and DO models has the potential to provide invaluable insights for translation of phytochemicals from rodents to humans, which are desperately needed given the challenges and numerous failed clinical trials in this field. These models may prove informative for personalized use of phytochemicals in humans, including: predicting interindividual variability in phytochemical bioavailability and efficacy, identifying genetic loci or genes governing response to phytochemicals, identifying phytochemical mechanisms of action and therapeutic targets, and understanding the impact of genetic variability on individual response to phytochemicals. Such insights would prove invaluable for personalized implementation of phytochemicals in humans. This review will focus on the current work performed with genetically diverse mouse populations, and the research opportunities and advantages that these models can offer to phytochemical research.

Abstract
BACKGROUND Most clinical allogeneic hemopoietic cell transplants (alloHCT) are now performed using reduced-intensity conditioning (RIC) instead of myeloablative conditioning (MAC); however, the biology underlying this treatment remains incompletely understood. METHODS We investigated a murine model of major histocompatibility complex-matched multiple minor histocompatibility antigen-mismatched alloHCT using bone marrow (BM) cells and splenocytes from B6 (H-2) donor mice transplanted into BALB.B (H-2) recipients after RIC with fludarabine of 100 mg/kg per day for 5 days, cyclophosphamide of 60 mg/kg per day for 2 days, and total body irradiation (TBI). RESULTS The lowest TBI dose capable of achieving complete donor chimerism in this mouse strain combination was 325 cGy given as a single fraction. Mice that underwent RIC had a reduced incidence and delayed onset of graft-versus-host disease (GVHD) and significantly prolonged survival compared with MAC-transplanted recipients (TBI of 850 cGy plus cyclophosphamide of 60 mg/kg per day for 2 days). Compared with syngeneic controls, RIC mice with GVHD showed evidence of BM suppression, have anemia, reduced BM cellularity, and showed profound reduction in BM B cell lymphopoiesis associated with damage to the endosteal BM niche. This was associated with an increase in BM CD8 effector T cells in RIC mice and elevated blood and BM plasma levels of T helper1 cytokines. Increasing doses of splenocytes resulted in increased incidence of GVHD in RIC mice. CONCLUSIONS We demonstrate that the BM is a major target organ of GVHD in an informative clinically relevant RIC mouse major histocompatibility complex-matched alloHCT model by a process that seems to be driven by CD8 effector T cells.

Xenogeneic cardiac extracellular matrix scaffolds with or without seeded mesenchymal stem cells exhibit distinct in vivo immunosuppressive and regenerative properties. Acta Biomater 2016; 45:155-168.

Abstract
Cardiac extracellular matrix (cECM) scaffolds are promising biomaterials for reconstructive surgery applications since they possess the structure/function properties of native tissue. Production of cECM scaffolds has been achieved using decellularization approaches, which commonly employ denaturing detergents, such as sodium dodecyl sulfate (SDS). Our antigen removal (AR) method has been shown to remove cellular and nonmyocyte components, while preserving cECM scaffold structure/function relationships. Here, we demonstrate that more human mesenchymal stem cells (MSCs) invaded AR scaffolds compared to SDS controls. Additionally, AR scaffolds stimulated a constructive remodeling response similar to allograft controls, and were transformed to adipose tissue in a xenogeneic rat to mouse subpannicular in vivo model. Conversely, SDS scaffolds showed a chronic inflammatory response that worsened throughout the 12-wk time course preventing constructive remodeling and mirroring the response seen towards xenogeneic tissue. AR scaffolds and xenogeneic controls recellularized with murine MSCs (mMSCs) were also implanted to assess whether mMSCs would offer any additive benefit in overcoming residual scaffold-specific immune responses. Paradoxically, recellularization resulted in chronic inflammatory response in AR-recellularized scaffolds. We conclude that AR cECM scaffolds represent a promising biomaterial, which is accepted by the recipient as self in origin and fosters implantation site appropriate regenerative responses. STATEMENT OF SIGNIFICANCE We demonstrated that an antigen-removal (AR) approach utilizing principles of differential solubility for production of a xenogeneic rat cardiac extracellular matrix scaffold results in improved recellularization efficiency with human and mouse mesenchymal stem cells (MSCs) in vitro. Furthermore, we tested the immune response to AR scaffolds versus allograft and xenograft controls with or without MSC recellularization using a rat to mouse subcutaneous model. We showed that AR scaffolds and allograft controls resulted in significant adipose tissue transformation after 12weeks. Paradoxically, MSCs had a positive impact in the immune response to xenografts, but had the opposite effect in AR scaffolds, resulting in chronic inflammatory response, which might be attributed to a change of their phenotype following recellularization into scaffolds.

Abstract
The intestinal microbiota and gut immune system must communicate to maintain a balance between tolerance and activation. Our immune system protects us from pathogenic microbes at the same time that our bodies are host to trillions of microbes, symbionts, mutualists, and some that are essential to human health. Since there is such a close interaction between the immune system and the intestinal microbiota, it is not surprising that some lymphomas such as mucosal-associated lymphoid tissue lymphoma have been shown to be caused by the presence of certain bacteria. Animal models have played an important role in elucidating the causation and establishing the mechanism of bacteria-induced mucosal-associated lymphoid tissue lymphoma. In this review, we discuss different ways that animal models have been applied to investigate links between the gut microbiota and lymphoma and have helped to reveal the mechanisms of microbiota-induced lymphoma. Although there is a paucity of published studies demonstrating the interplay between the microbiota and lymphoma development, we believe that the connection is real and that it can be exploited in the future to enhance our understanding of causation and to improve the prognosis and treatment of lymphoma.

Abstract
![]()
The
severity and longevity of the current Ebola outbreak highlight
the need for a fast-acting yet long-lasting vaccine for at-risk populations
(medical personnel and rural villagers) where repeated prime-boost
regimens are not feasible. While recombinant adenovirus (rAd)-based
vaccines have conferred full protection against multiple strains of
Ebola after a single immunization, their efficacy is impaired by pre-existing
immunity (PEI) to adenovirus. To address this important issue, a panel
of formulations was evaluated by an in vitro assay
for their ability to protect rAd from neutralization. An amphiphilic
polymer (F16, FW ∼39,000) significantly improved transgene
expression in the presence of anti-Ad neutralizing antibodies (NAB)
at concentrations of 5 times the 50% neutralizing dose (ND50). In vivo performance of rAd in F16 was compared
with unformulated virus, virus modified with poly(ethylene) glycol
(PEG), and virus incorporated into poly(lactic-co-glycolic) acid (PLGA) polymeric beads. Histochemical analysis of
lung tissue revealed that F16 promoted strong levels of transgene
expression in naive mice and those that were exposed to adenovirus
in the nasal cavity 28 days prior to immunization. Multiparameter
flow cytometry revealed that F16 induced significantly more polyfunctional
antigen-specific CD8+ T cells simultaneously producing
IFN-γ, IL-2, and TNF-α than other test formulations. These
effects were not compromised by PEI. Data from formulations that provided
partial protection from challenge consistently identified specific
immunological requirements necessary for protection. This approach
may be useful for development of formulations for other vaccine platforms
that also employ ubiquitous pathogens as carriers like the influenza
virus.

Abstract
Gastrointestinal illnesses are a significant health burden for the US population, with 40 million office visits each year for gastrointestinal complaints and nearly 250,000 deaths. Acute and chronic inflammations are a common element of many gastrointestinal diseases. Inflammatory processes may be initiated by a chemical injury (acid reflux in the esophagus), an infectious agent (Helicobacter pylori infection in the stomach), autoimmune processes (graft versus host disease after bone marrow transplantation), or idiopathic (as in the case of inflammatory bowel diseases). Inflammation in these settings can contribute to acute complaints (pain, bleeding, obstruction, and diarrhea) as well as chronic sequelae including strictures and cancer. Research into the pathophysiology of these conditions has been limited by the availability of primary human tissues or appropriate animal models that attempt to physiologically model the human disease. With the many recent advances in tissue engineering and primary human cell culture systems, it is conceivable that these approaches can be adapted to develop novel human ex vivo systems that incorporate many human cell types to recapitulate in vivo growth and differentiation in inflammatory microphysiological environments. Such an advance in technology would improve our understanding of human disease progression and enhance our ability to test for disease prevention strategies and novel therapeutics. We will review current models for the inflammatory and immunological aspects of Barrett's esophagus, acute graft versus host disease, and inflammatory bowel disease and explore recent advances in culture methodologies that make these novel microphysiological research systems possible.

Abstract
The intestinal microbiota and gut immune system must constantly communicate to maintain a balance between tolerance and activation: on the one hand, our immune system should protect us from pathogenic microbes and on the other hand, most of the millions of microbes in and on our body are innocuous symbionts and some can even be beneficial. Since there is such a close interaction between the immune system and the intestinal microbiota, it is not surprising that some lymphomas such as mucosal-associated lymphoid tissue (MALT) lymphoma have been shown to be caused by the presence of certain bacteria. Animal models played an important role in establishing causation and mechanism of bacteria-induced MALT lymphoma. In this review we discuss different ways that animal models have been applied to establish a link between the gut microbiota and lymphoma and how animal models have helped to elucidate mechanisms of microbiota-induced lymphoma. While there are not a plethora of studies demonstrating a connection between microbiota and lymphoma development, we believe that animal models are a system which can be exploited in the future to enhance our understanding of causation and improve prognosis and treatment of lymphoma.

Abstract
Both human cytomegalovirus (HCMV) and murine cytomegalovirus (MCMV) establish persistent infections that induce the accumulation of virus-specific T cells over time in a process called memory inflation. It has been proposed that T cells expressing T-cell receptors (TCRs) with high affinity for HCMV-derived peptides are preferentially selected after acute HCMV infection. To test this in the murine model, small numbers of OT-I transgenic T cells, which express a TCR with high affinity for the SIINFEKL peptide, were transferred into congenic mice and recipients were challenged with recombinant MCMV expressing SIINFEKL. OT-I T cells were selectively enriched during the first 3 weeks of infection. Similarly, in the absence of OT-I T cells, the functional avidity of SIINFEKL-specific T cells increased from early to late times postinfection. However, even when exceedingly small numbers of OT-I T cells were transferred, their inflation limited the inflation of host-derived T cells specific for SIINFEKL. Importantly, subtle minor histocompatibility differences led to late rejection of the transferred OT-I T cells in some mice, which allowed host-derived T cells to inflate substantially. Thus, T cells with a high functional avidity are selected shortly after MCMV infection and continuously sustain their clonal dominance in a competitive manner.

Abstract
The limiting factor for successful hematopoietic stem cell transplantation (HSCT) is graft-versus-host disease (GvHD), a post-transplant disorder that results from immune-mediated attack of recipient tissue by donor T cells contained in the transplant. Mouse models of GvHD have provided important insights into the pathophysiology of this disease, which have helped to improve the success rate of HSCT in humans. The kinetics with which GvHD develops distinguishes acute from chronic GvHD, and it is clear from studies of mouse models of GvHD (and studies of human HSCT) that the pathophysiology of these two forms is also distinct. Mouse models also further the basic understanding of the immunological responses involved in GvHD pathology, such as antigen recognition and presentation, the involvement of the thymus and immune reconstitution after transplantation. In this Perspective, we provide an overview of currently available mouse models of acute and chronic GvHD, highlighting their benefits and limitations, and discuss research and clinical opportunities for the future.
