Abstract
Olfactory disorders may be temporary or permanent and can have various causes. Currently, many COVID-19 patients report a reduced or complete loss of olfactory function. A wide range of treatment options have been investigated in the past, such as olfactory training, acupuncture, medical therapy, transcranial magnetic stimulation, or surgical excision of olfactory epithelium, e.g., in severe qualitative smell disorders. The development of a bioelectric nose, e.g., in connection with direct electrical stimulation or transplantation of olfactory epithelium or stem cells, represent treatment options of the future. The basis of these developments and the state of knowledge is discussed in the following work.

Abstract
The sense of smell is important. This became especially clear to patients with infection-related olfactory loss during the SARS-CoV-2 pandemic. We react, for example, to the body odors of other humans. The sense of smell warns us of danger, and it allows us to perceive flavors when eating and drinking. In essence, this means quality of life. Therefore, anosmia must be taken seriously. Although olfactory receptor neurons are characterized by regenerative capacity, anosmia is relatively common with about 5 % of anosmic people in the general population. Olfactory disorders are classified according to their causes (e. g., infections of the upper respiratory tract, traumatic brain injury, chronic rhinosinusitis, age) with the resulting different therapeutic options and prognoses. Thorough history taking is therefore important. A wide variety of tools are available for diagnosis, ranging from short screening tests and detailed multidimensional test procedures to electrophysiological and imaging methods. Thus, quantitative olfactory disorders are easily assessable and traceable. For qualitative olfactory disorders such as parosmia, however, no objectifying diagnostic procedures are currently available. Therapeutic options for olfactory disorders are limited. Nevertheless, there are effective options consisting of olfactory training as well as various additive drug therapies. The consultation and the competent discussion with the patients are of major importance.

Abstract
In recent years, there has been increasing interest in the treatment of bone defects using undifferentiated mesenchymal stem cells (MSCs) in vivo. Recently, dental pulp has been proposed as a promising source of pluripotent mesenchymal stem cells (MSCs), which can be used in various clinical applications. Dentin is the hard tissue that makes up teeth, and has the same composition and strength as bone. However, unlike bone, dentin is usually not remodeled under physiological conditions. Here, we generated odontoblast-like cells from mouse dental pulp stem cells and combined them with honeycomb tricalcium phosphate (TCP) with a 300 μm hole to create bone-like tissue under the skin of mice. The bone-like hard tissue produced in this study was different from bone tissue, i.e., was not resorbed by osteoclasts and was less easily absorbed than the bone tissue. It has been suggested that hard tissue-forming cells induced from dental pulp do not have the ability to induce osteoclast differentiation. Therefore, the newly created bone-like hard tissue has high potential for absorption-resistant hard tissue repair and regeneration procedures.

Abstract
Passagere oder permanente Riechstörungen können verschiedene Ursachen haben. Ganz aktuell berichtet eine Vielzahl von Patienten im Rahmen von COVID-19-Infektionen über ein fehlendes oder vermindertes Riechvermögen. In der Vergangenheit wurden vielfältige Therapieoptionen untersucht, diese variieren vom Riechtraining über Akupunktur und medikamentöse Therapien bis hin zur transkraniellen Magnetstimulation oder, z. B. bei ausgeprägten qualitativen Riechstörungen, der chirurgischen Resektion der Riechschleimhaut. Die Entwicklung einer bioelektrischen Nase, z. B. in Verbindung mit direkter elektrischer Stimulation des Bulbus olfactorius, oder die Transplantation von Riechschleimhaut oder von Stammzellen stellen Behandlungsmöglichkeiten der Zukunft dar. Die Grundlagen für diese Entwicklungen sowie der Stand des Wissens werden in der vorliegenden Arbeit erläutert.

Abstract
The stroma affects the properties and dynamics of the tumor. Previous studies have demonstrated that bone marrow-derived cells (BMDCs) possess the capability of differentiating into stromal cells. However, the characteristics and roles of BMDCs in oral squamous cell carcinoma remain unclear. The current study therefore investigated their locations and features by tracing green fluorescent protein (GFP)-labeled BMDCs in a transplantation mouse model. After irradiation, BALB-c nu-nu mice were injected with bone marrow cells from C57BL/6-BALB-C-nu/nu-GFP transgenic mice. These recipient mice were then injected subcutaneously in the head with human squamous cell carcinoma-2 cells. Immunohistochemistry for GFP, Vimentin, CD11b, CD31 and α-smooth muscle actin (SMA), and double-fluorescent immunohistochemistry for GFP-Vimentin, GFP-CD11b, GFP-CD31 and GFP-α-SMA was subsequently performed. Many round-shaped GFP-positive cells were observed in the cancer stroma, which indicated that BMDCs served a predominant role in tumorigenesis. Vimentin(+) GFP(+) cells may also be a member of the cancer-associated stroma, originating from bone marrow. Round or spindle-shaped CD11b(+) GFP(+) cells identified in the present study may be macrophages derived from bone marrow. CD31(+)GFP(+) cells exhibited a high tendency towards bone marrow-derived angioblasts. The results also indicated that spindle-shaped α-SMA(+) GFP(+) cells were not likely to represent bone marrow-derived cancer-associated fibroblasts. BMDCs gathering within the tumor microenvironment exhibited multilineage potency and participated in several important processes, such as tumorigenesis, tumor invasion and angiogenesis.

Abstract
Multipotential ability of bone marrow-derived cells has been clarified, and their involvement in repair and maintenance of various tissues has been reported. However, the role of bone marrow-derived cells in osteogenesis remains unknown. In the present study, bone marrow-derived cells during ectopic bone formation of mouse femoral muscle were traced using a GFP bone marrow transplantation model. Bone marrow cells from C57BL/6-Tg (CAG-EGFP) mice were transplanted into C57BL/6 J wild type mice. After transplantation, insoluble bone matrix (IBM) was implanted into mouse muscle. Ectopic bone formation was histologically assessed at postoperative days 7, 14, and 28. Immunohistochemistry for GFP single staining and GFP-osteocalcin double staining was then performed. Bone marrow transplantation successfully replaced hematopoietic cells with GFP-positive donor cells. Immunohistochemical analyses revealed that osteoblasts and osteocytes involved in ectopic bone formation were GFP-negative, whereas osteoclasts and hematopoietic cells involved in bone formation were GFP-positive. These results indicate that bone marrow-derived cells might not differentiate into osteoblasts. Thus, the main role of bone marrow-derived cells in ectopic osteogenesis may not be to induce bone regeneration by differentiation into osteoblasts, but rather to contribute to microenvironment formation for bone formation by differentiating tissue stem cells into osteoblasts.

Abstract
Background: The tumor microenvironment and its stromal cells play an important role in cancer development and metastasis. Bone marrow-derived cells (BMDCs), a rich source of hematopoietic and mesenchymal stem cells, putatively contribute to this tumoral stroma. However their characteristics and roles within the tumor microenvironment are unclear. In the present study, BMDCs in the tumor microenvironment were traced using the green fluorescent protein (GFP) bone marrow transplantation model. Methods: C57BL/6 mice were irradiated and rescued by bone marrow transplantation from GFP-transgenic mice. Lewis lung cancer cells were inoculated into the mice to generate subcutaneous allograft tumors or lung metastases. Confocal microscopy, immunohistochemistry for GFP, α-SMA, CD11b, CD31, CD34 and CD105, and double-fluorescent immunohistochemistry for GFP-CD11b, GFP-CD105 and GFP-CD31 were performed. Results: Round and dendritic-shaped GFP-positive mononuclear cells constituted a significant stromal subpopulation in primary tumor peripheral area (PA) and metastatic tumor area (MA) microenvironment, thus implicating an invasive and metastatic role for these cells. CD11b co-expression in GFP-positive cells suggests that round/dendritic cell subpopulations are possibly BM-derived macrophages. Identification of GFP-positive mononuclear infiltrates co-expressing CD31 suggests that these cells might be BM-derived angioblasts, whereas their non-reactivity for CD34, CD105 and α-SMA implies an altered vascular phenotype distinct from endothelial cells. Significant upregulation of GFP-positive, CD31-positive and GFP/CD31 double-positive cell densities positively correlated with PA and MA (P<0.05). Conclusion: Taken together, in vivo evidence of traceable GFP-positive BMDCs in primary and metastatic tumor microenvironment suggests that recruited BMDCs might partake in cancer invasion and metastasis, possess multilineage potency and promote angiogenesis.

Olfactory bulb plasticity ensures proper olfaction after severe impairment in postnatal neurogenesis. Sci Rep 2017; 7:5654.

Abstract
The olfactory bulb (OB) neurons establish a complex network that ensures the correct processing of the olfactory inputs. Moreover, the OB presents a lifelong addition of new neurons into its existing circuitry. This neurogenesis is considered essential for the OB function. However, its functional impact on physiology and behavior is still unclear. Here, we investigate the mechanisms of OB plasticity that underlie bulbar physiology in relation to severe damage of neurogenesis. The neurogenesis of young mice was altered by ionizing radiation. Afterwards, both multi-channel olfactometry and electrophysiological studies were performed. Furthermore, neurogenesis and differentiation of the newly formed cells were assessed using bromodeoxyuridine labeling combined with a wide battery of neuronal markers. Our results demonstrate a reduction in both neurogenesis and volume of the OB in irradiated animals. The number of neuroblasts reaching the OB was reduced and their differentiation rate into interneurons selectively changed; some populations were noticeably affected whereas others remained preserved. Surprisingly, both olfactory detection and discrimination as well as electrophysiology presented almost no alterations in irradiated mice. Our findings suggest that after damaging postnatal neurogenesis, the neurochemical fate of some interneurons changes within a new biological scenario, while maintaining homeostasis and olfaction.

Abstract
CONCLUSION Bone marrow-derived cells can be engrafted in the olfactory bulb and a few cells can differentiate into mitral/tufted cells in the olfactory bulb. OBJECTIVES To investigate whether bone marrow-derived cells can be engrafted into the olfactory bulb and differentiate into neurons and glial cells after methimazole administration. METHODS Bone marrow of GFP (green fluorescence protein) mice was transplanted into lethally irradiated recipient mice. Immunostaining was performed to confirm the cell types of bone marrow-derived cells expressing GFP. RESULTS GFP-positive cells were observed in the olfactory bulb at 2 days after methimazole administration. The number of dendritic GFP-positive cells increased up to 30 days after methimazole administration and then decreased. Double immunostaining for GFP and Iba1 or TBX21 showed that a large population of the GFP-positive cells had characteristics of microglia/macrophages and a few cells had characteristics of mitral/tufted cells.

Abstract
Bone healing is a complex and multistep process in which the origin of the cells participating in bone repair is still unknown. The involvement of bone marrow-derived cells in tissue repair has been the subject of recent studies. In the present study, bone marrow-derived cells in bone healing were traced using the GFP bone marrow transplantation model. Bone marrow cells from C57BL/6-Tg (CAG-EGFP) were transplanted into C57BL/6 J wild mice. After transplantation, bone injury was created using a 1.0-mm drill. Bone healing was histologically assessed at 3, 7, 14, and 28 postoperative days. Immunohistochemistry for GFP; double-fluorescent immunohistochemistry for GFP-F4/80, GFP-CD34, and GFP-osteocalcin; and double-staining for GFP and tartrate-resistant acid phosphatase were performed. Bone marrow transplantation successfully replaced the hematopoietic cells into GFP-positive donor cells. Immunohistochemical analyses revealed that osteoblasts or osteocytes in the repair stage were GFP-negative, whereas osteoclasts in the repair and remodeling stages and hematopoietic cells were GFP-positive. The results indicated that bone marrow-derived cells might not differentiate into osteoblasts. The role of bone marrow-derived cells might be limited to adjustment of the microenvironment by differentiating into inflammatory cells, osteoclasts, or endothelial cells in immature blood vessels.

Abstract
BACKGROUND Bone marrow-derived cells (BMCs) have abilities of cell migration and differentiation into tissues/organs in the body and related with the differentiation of teeth or periodontal tissue including fibroblasts. Then, we examined the effect of orthodontic mechanical stress to the transplanted BMC migration into periodontal tissues using BMC transplantation model. MATERIAL AND METHOD BMC from green fluorescence protein (GFP) transgenic mice were transplanted into 8-week-old female C57BL/6 immunocompromised recipient mice, which had undergone 10 Gy of lethal whole-body-irradiation. Five mice as experimental group were received orthodontic mechanical stress using separator between first molar (M1) and second molar (M2) 1 time per week for 5 weeks and 5 mice as control group were not received mechanical stress. The maxilla with M1 and M2 was removed and was immunohistochemically analyzed using a Dako Envision + Kit-K4006 and a primary anti-GFP-polyclonal rabbit antibody. Immunohistochemically stained was defined as positive area and the pixel number of positive area in the periodontal tissue was compared with the previously calculated total pixel number of the periodontal tissue. RESULTS The immunohistochemistry revealed that GFP positive cells were detected in the periodontal tissues, both in the experimental and control specimens. The ratio of pixel number in the examination group showed 5.77 ± 3.24 % (mean ± SD); and that in the control group, 0.71 ± 0.45 % (mean ± SD). The examination group was significantly greater than that of control group (Mann-Whitney U test: p<0.001). CONCLUSION These results suggest that orthodontic mechanical stress accelerates transplanted BMC migration into periodontal tissues.

Abstract
Bone marrow contains heterogeneous cell types including end-lineage cells, committed tissue progenitors, and multipotent stem/progenitor cells. The immense plasticity of bone marrow cells allows them to populate diverse tissues such as the encephalon, and give rise to a variety of cell types. This unique plasticity makes bone marrow-derived cells good candidates for cell therapy aiming at restoring impaired brain circuits. In the present study, bone marrow cells were transplanted into P20 mice that exhibit selective olfactory degeneration in adulthood between P60 and P150. These animals, the so-called Purkinje Cell Degeneration (PCD) mutant mice, suffer from a progressive and specific loss of a subpopulation of principal neurons of the olfactory bulb, the mitral cells (MCs), sparing the other principal neurons, the tufted cells. As such, PCD mice constitute an interesting model to evaluate the specific role of MCs in olfaction and to test the restorative function of transplanted bone marrow-derived cells. Using precision olfactometry, we revealed that mutant mice lacking MCs exhibited a deficit in odorant detection and discrimination. Remarkably, the transplantation of wild-type bone marrow-derived cells into irradiated PCD mutant mice generated a large population of microglial cells in the olfactory bulb and reduced the degenerative process. The alleviation of MC loss in transplanted mice was accompanied by functional recovery witnessed by significantly improved olfactory detection and enhanced odor discrimination. Together, these data suggest that: (1) bone marrow-derived cells represent an effective neuroprotective tool to restore degenerative brain circuits, and (2) MCs are necessary to encode odor concentration and odor identity in the mouse olfactory bulb.

Abstract
Bone marrow (BM) cells from amyotrophic lateral sclerosis (ALS) patients show significantly reduced expression of several neurotrophic factors. Monotherapy with either wild-type (WT) BM transplantation (BMT) or granulocyte colony-stimulating factor (GCSF) has only a small clinical therapeutic effect in an ALS mouse model, due to the phenomenon of neuroprotection. In this study, we investigated the clinical benefits of combination therapy using BMT with WT BM cells, plus GCSF after disease onset in ALS mice [transgenic mice expressing human Cu/Zn superoxide dismutase (SOD1) bearing a G93A mutation]. Combined treatment with BMT and GCSF delayed disease progression and prolonged the survival of G93A mice, whereas BMT or GCSF treatment alone did not. Histological study of the ventral horns of lumbar cords from G93A mice treated with BMT and GCSF showed a reduction in motor neuron loss coupled with induced neuronal precursor cell proliferation, increased expression of neurotrophic factors (glial cell line-derived neurotrophic factor, brain-derived neurotrophic factor, vascular endothelial growth factor and angiogenin), and neovascularization compared with controls (vehicle only). Compared with G93A microglial cells, most BM-derived WT cells differentiated into microglial cells and strongly expressed neurotrophic factors, combined BMT and GCSF treatment led to the replacement of G93A microglial cells with BM-derived WT cells. These results indicate combined treatment with BMT and GCSF has potential neuroprotective and angiogenic effects in ALS mice, induced by the replacement of G93A microglial cells with BM-derived WT cells. Furthermore, this is the first report showing the effects of combined BMT and GCSF treatment on blood vessels in ALS.

Abstract
OBJECTIVES We sought to develop a new therapeutic strategy for degeneration of olfactory receptor neurons (ORNs). METHODS We transplanted into Balb/C mice, locally by transnasal injection and systemically via the tail vain, BrdU-labeled bone marrow stem cells, also known as NRGs, which have the ability to differentiate into neural cells. Bone marrow stem cells engrafted into the olfactory epithelium were examined immunohistochemically. RESULTS Compared with previous studies, in which bone marrow was transplanted rather than bone marrow stem cells, migration of transplanted bone marrow stem cells into the olfactory epithelium was observed earlier, and engraftment rates were significantly higher. However, migrated bone marrow stem cells were positive for GAP43 but not for olfactory marker protein. CONCLUSIONS These results suggest that engrafted cells had differentiated into premature, but not mature, ORNs. Further experiments using autologous bone marrow stem cells in combination with various growth factors and/or neurotrophic factors should aid the development of new therapeutic methods for degenerated ORNs.

Abstract
OBJECTIVES Treating olfactory dysfunction is a challenge for physicians. One of the therapeutic options could be transplantation of stem cells. In this study, neural stem cells were transplanted into anosmic mice. METHODS Neural stem cells were generated from the olfactory bulb of green fluorescent protein (GFP)-transgenic C57BL6 mice. Anosmia were induced by injection of intraperitoneal 3-methylindole. The neural stem cells were transplanted transnasally on the next day. The olfactory function was evaluated by a food-finding test once a week. The olfactory neuroepithelium was harvested for histologic examination and protein analysis at 4 weeks. RESULTS Twenty-five percent (6/24) of the control mice that were not transplanted with neural stem cells survived at 4 weeks while 67% (8/12) of the transplanted mice survived (P=0.029). The food finding test showed that the transplanted mice resumed finding food at 3 weeks while the control mice resumed finding food at 4 weeks. GFP-positive cells were observed in the olfactory neuroepithelium of the transplanted mice. Western blotting revealed that the olfactory marker protein expression was significantly lower in the control mice than that in the transplanted mice. CONCLUSION This study demonstrated that improvement of mouse survival was achieved and recovery of olfactory function was promoted by transnasal transplantation of neural stem cells in the anosmic mouse model. These results indicate that stem cells might be one of the future modalities for treating olfactory impairment.

Abstract
To investigate whether bone marrow-derived cells (BMC) would migrate and engraft into the sensory epithelium of the inner ear, BMC of green fluorescence protein (GFP) mice were transplanted into lethally irradiated recipient mice. Then the recipient mice were treated with streptomycin and immunohistochemical staining was performed to evaluate the migration and engraftment of donor BMC into the sensory epithelium of the inner ear. Immunohistochemical staining for GFP was found initially in the vascular epithelium and oral mucosa but not in the sensory epithelium of the inner ear. In the case of mouse, BMC may not migrate and be engrafted into the sensory epithelium of the inner ear.

Abstract
Abstract The remarkable plasticity of marrow stromal cells (MSCs) after transplantation to models of neurological disease and injury has been described. In this report, we investigated the plasticity and long-term survival of MSCs transplanted into the normal brain. MSCs were isolated from green fluorescent protein (GFP) transgenic rats and double-labeled with 5-bromo-2-deoxyuridine (BrdU) and bis benzamide (BBZ) prior to transplantation into the adult hippocampus or striatum. Surgery elicited an immediate inflammatory response. MSC grafts were massively infiltrated by ED1-positive microglia/macrophages and surrounded by a marked astrogliosis. By 14 days, graft volume had retracted and GFP immunoreactivity was absent, indicating complete donor rejection. Consequently, MSCs did not exhibit plasticity formerly identified in other studies. However, BrdU- and BBZ-labeled cells were detected up to 12 weeks. Control transplants of nonviable MSCs demonstrated the transfer of donor labels to host cells. Unexpectedly, BrdU labeling was colocalized to host phagocytes, astrocytes, and neurons in both regions. Our results indicate that MSCs transplanted to the intact adult brain are rejected by an inflammatory response. Moreover, use of the traditional cell labels BrdU and BBZ may provide a misleading index of donor survival and differentiation after transplantation.
