Abstract
There has been only limited success to differentiate adult stem cells into cardiomyocyte subtypes. In the present study, we have successfully induced beating atrial and ventricular cardiomyocytes from rat hair-follicle-associated pluripotent (HAP) stem cells, which are adult stem cells located in the bulge area. HAP stem cells differentiated into atrial cardiomyocytes in culture with the combination of isoproterenol, activin A, bone morphogenetic protein 4 (BMP4), basic fibroblast growth factor (bFGF), and cyclosporine A (CSA). HAP stem cells differentiated into ventricular cardiomyocytes in culture with the combination of activin A, BMP4, bFGF, inhibitor of Wnt production-4 (IWP4), and vascular endothelial growth factor (VEGF). Differentiated atrial cardiomyocytes were specifically stained for anti-myosin light chain 2a (MLC2a) antibody. Ventricular cardiomyocytes were specially stained for anti-myosin light chain 2v (MLC2v) antibody. Quantitative Polymerase Chain Reaction (qPCR) showed significant expression of MLC2a in atrial cardiomyocytes and MLC2v in ventricular cardiomyocytes. Both differentiated atrial and ventricular cardiomyocytes showed characteristic waveforms in Ca2+ imaging. Differentiated atrial and ventricular cardiomyocytes formed long myocardial fibers and beat as a functional syncytium, having a structure similar to adult cardiomyocytes. The present results demonstrated that it is possible to induce cardiomyocyte subtypes, atrial and ventricular cardiomyocytes, from HAP stem cells.

Abstract
Intracerebral hemorrhage (ICH) is a leading cause of mortality with ineffective treatment. Hair-follicle-associated pluripotent (HAP) stem cells can differentiate into neurons, glial cells and many other types of cells. HAP stem cells have been shown to repair peripheral-nerve and spinal-cord injury in mouse models. In the present study, HAP stem cells from C57BL/6J mice were implanted into the injured brain of C57BL/6J or nude mice with induced ICH. After allo transplantation, HAP stem cells differentiated to neurons, astrocytes, oligodendrocytes, and microglia in the ICH site of nude mice. After autologous transplantation in C57BL/6J mice, HAP stem cells suppressed astrocyte and microglia infiltration in the injured brain. The mRNA expression levels of IL-10 and TGF-β1, measured by quantitative Real-Time RT-PCR, in the brain of C57BL/6J mice with ICH was increased by HAP-stem-cell implantation compared to the non-implanted mice. Quantitative sensorimotor function analysis, with modified limb-placing test and the cylinder test, demonstrated a significant functional improvement in the HAP-stem-cell-implanted C57BL/6J mice, compared to non-implanted mice. HAP stem cells have critical advantages over induced pluripotent stem cells, embryonic stem cells as they do not develop tumors, are autologous, and do not require genetic manipulation. The present study demonstrates future clinical potential of HAP-stem-cell repair of ICH, currently a recalcitrant disease.

Abstract
Chronic spinal cord injury (SCI) is a highly debilitating and recalcitrant disease with limited treatment options. Although various stem cell types have shown some clinical efficacy for injury repair they have not for SCI. Hair-follicle-associated pluripotent (HAP) stem cells have been shown to differentiate into neurons, Schwan cells, beating cardiomyocytes and many other type of cells, and have effectively regenerated acute spinal cord injury in mouse models. In the present report, HAP stem cells from C57BL/6J mice, encapsulated in polyvinylidene fluoride membranes (PFM), were implanted into the severed thoracic spinal cord of C57BL/6J or athymic nude mice in the early chronic phase. After implantation, HAP stem cells differentiated to neurons, astrocytes and oligodendrocytes in the regenerated thoracic spinal cord of C57BL/6J and nude mice. Quantitative motor function analysis, with the Basso Mouse Scale for Locomotion (BMS) score, demonstrated a significant functional improvement in the HAP-stem-cell-implanted mice, compared to non-implanted mice. HAP stem cells have critical advantages over other stem cells: they do not develop teratomas; do not loose differentiation ability when cryopreserved and thus are bankable; are autologous, readily obtained from anyone; and do not require genetic manipulation. HAP stem cells therefore have greater clinical potential for SCI repair than induced pluripotent stem cells (iPSCs), neuronal stem cells (NSCs)/neural progenitor cells (NPCs) or embryonic stem cells (ESCs). The present report demonstrates future clinical potential of HAP-stem-cell repair of chronic spinal cord injury, currently a recalcitrant disease.

Abstract
Hair-follicle-associated pluripotent (HAP) stem cells are located in the bulge area of hair follicles from mice and humans and have been shown to differentiate to neurons, glia, keratinocytes, smooth muscle cells, melanocytes and beating cardiac muscle cells in vitro. Subsequently, we demonstrated that HAP stem cells could effect nerve and spinal-cord regeneration in mouse models, differentiating to Schwann cells and neurons in this process. HAP stem cells can be banked by cryopreservation and preserve their ability to differentiate. In the present study, we demonstrated that mouse HAP stem cells cultured in neural-induction medium can extensively differentiate to dopaminergic neurons, which express tyrosine hydroxylase and secrete dopamine. These results indicate that the dopaminergic neurons differentiated from HAP stem cells may be useful in the future to improve the symptoms of Parkinson's disease in the clinic.

Abstract
Our previous studies showed that nestin-expressing hair follicle-associated-pluripotent (HAP) stem cells, which reside in the bulge area of the hair follicle, could restore injured nerve and spinal cord and differentiate into cardiac muscle cells. Here we transplanted mouse green fluorescent protein (GFP)-expressing HAP stem-cell colonies enclosed on polyvinylidene fluoride membranes (PFM) into the severed thoracic spinal cord of nude mice. After seven weeks of implantation, we found the differentiation of HAP stem cells into neurons and glial cells. Our results also showed that PFM-captured GFP-expressing HAP stem-cell colonies assisted complete reattachment of the thoracic spinal cord. Furthermore, our quantitative motor function analysis with the Basso Mouse Scale for Locomotion (BMS) score demonstrated a significant improvement in the implanted mice compared to non-implanted mice with a severed spinal cord. Our study also showed that it is easy to obtain HAP stem cells, they do not develop teratomas, and do not loose differentiation ability when cryopreserved. Collectively our results suggest that HAP stem cells could be a better source compared to induced pluripotent stem cells (iPS) or embryonic stem (ES) cells for regenerative medicine, specifically for spinal cord repair.

Abstract
Hair-follicle-associated pluripotent (HAP) stem cells reside in the upper part of the bulge area of the the hair follicle. HAP stem cells are nestin-positive and keratin 15-negative and have the capacity to differentiate into various types of cells in vitro. HAP stem cells are also involved in nerve and spinal cord regeneration in mouse models. Recently, it was shown that the DNA-damage response in non-HAP hair follicle stem cells induces proteolysis of type-XVII collagen (COL17A1/BP180), which is involved in hair-follicle stem-cell maintenance. COL17A1 proteolysis stimulated hair-follicle stem-cell aging, characterized by the loss of stemness signatures and hair-follicle miniaturization associated with androgenic alopecia. In the present study, we demonstrate that HAP stem cells co-express nestin and COL17A1 in vitro and in vivo. The expression of HAP stem cell markers (nestin and SSEA1) increased after HAP stem-cell colonies were formed, then decreased after differentiation to epidermal keratinocytes. In contrast COL17A1 increased after differentiation to epidermal keratinocytes. These results suggest that COL17A1 is important in differentiation of HAP stem cells.

Abstract
The bulge area of the hair follicle contains hair-follicle-associated pluripotent (HAP) stem cells. Here, we present effective cryopreservation procedures of the human hair follicle that preserve the differentiation potential of HAP stem cells. Whole hair follicles isolated from human scalp were cryopreserved by a slow-rate cooling medium and stored in liquid nitrogen. A careful thawing method was used to collect the upper parts of the human hair follicles which were cultured for four weeks in a Dulbecco’s Modified Eagle’s Medium with fetal bovine serum (FBS). Proliferating hair follicle cells were then shifted to DMEM/Ham’s Nutrient Mixture F-12 medium without FBS and allowed to grow for one week. These proliferating cells were able to produce HAP stem cell colonies with multilineage differentiation capacity. They produced keratinocytes, smooth muscle cells, cardiac muscle cells, neurons and glial cells. Interestingly, these cryopreserved hair follicles produced pluripotent HAP stem cell colonies similar to fresh follicles. These findings suggest that the cryopreserved whole human hair follicle preserves the ability to produce HAP stem cells, which will enable any individual to preserve a bank of these stem cells for personalized regenerative medicine.

Abstract
Abstract
Objective
To clarify the incidence, risk factors, and impact of malignancy in patients with PM/DM-associated interstitial lung disease (ILD).
Methods
This study used data from 497 patients with PM/DM-associated ILD enrolled in a multicentre, retrospective and prospective cohort of incident cases. Cancer-associated myositis (CAM) was defined as malignancy diagnosed within 3 years before or after PM/DM diagnosis. Demographic and clinical information was recorded at the time of diagnosis, and data about the occurrence of mortality and malignancy was collected.
Results
CAM was identified in 32 patients with PM/DM-associated ILD (6.4%). Patients with CAM were older (64 vs 55 years, P < 0.001), presented with arthritis less frequently (24% vs 49%, P = 0.01), and showed a lower level of serum Krebs von den Lungen-6 (687 vs 820 IU/l, P = 0.03) than those without CAM. The distribution of myositis-specific autoantibodies, including anti-melanoma differentiation–associated gene 5, anti-aminoacyl tRNA synthetase, and anti-transcriptional intermediary factor 1-γ antibodies, did not differ between the groups. Survival analysis demonstrated that CAM patients had a poorer survival than non-CAM patients (P = 0.006), primarily due to excess deaths by concomitant malignancy, while mortality due to ILD-related respiratory failure was similar between the groups (P = 0.51).
Conclusion
Concomitant malignancy can occur in patients with PM/DM-associated ILD, and has significant impact on mortality. Older age, lack of arthritis, and a lower level of serum Krebs von den Lungen-6 at diagnosis are predictors of concomitant malignancy.

Abstract
Hair follicle-associated-pluripotent (HAP) stem cells are located in the bulge area of the hair follicle, express the stem-cell marker, nestin, and have been shown to differentiate to nerve cells, glial cells, keratinocytes, smooth muscle cells, cardiac muscle cells, and melanocytes. Transplanted HAP stem cells promote the recovery of peripheral nerve and spinal cord injuries and have the potential for heart regeneration as well. In the present study, we implanted mouse green fluorescent protein (GFP)-expressing HAP stem-cell spheres encapsulated in polyvinylidene fluoride (PVDF)-membrane cylinders into the severed sciatic nerve of immunocompetent and immunocompromised (nude) mice. Eight weeks after implantation, immunofluorescence staining showed that the HAP stem cells differentiated into neurons and glial cells. Fluorescence microscopy showed that the HAP stem cell hair spheres promoted rejoining of the sciatic nerve of both immunocompetent and immunodeficient mice. Hematoxylin and eosin (H&E) staining showed that the severed scatic nerves had regenerated. Quantitative walking analysis showed that the transplanted mice recovered the ability to walk normally. HAP stem cells are readily accessible from everyone, do not form tumors, and can be cryopreserved without loss of differentiation potential. These results suggest that HAP stem cells may have greater potential than iPS or ES cells for regenerative medicine.

HAP stem cells effected nerve and spinal cord regeneration in mouse models. Recently, we demonstrated that HAP stem cells differentiated to beating cardiac muscle cells. The differentiation potential to cardiac muscle cells was greatest in the upper part of the follicle. The beat rate of the cardiac muscle cells was stimulated by isoproterenol. In the present study, we observed that isoproterenol directs HAP stem cells to differentiate to cardiac muscle cells in large numbers in culture compared to HAP stem cells not supplemented with isoproterenol. The addition of activin A, bone morphogenetic protein 4, and basic fibroblast growth factor, along with isoproternal, induced the cardiac muscle cells to form tissue sheets of beating heart muscle cells. These results demonstrate that HAP stem cells have great potential to form beating cardiac muscle cells in tissue sheets.

Abstract
We have previously demonstrated that nestin-expressing hair follicle-associated-pluripotent (HAP) stem cells are located in the bulge area. HAP stem cells have been previously shown to differentiate to neurons, glial cells, keratinocytes, smooth-muscle cells, melanocytes and cardiac-muscle cells in vitro. Subsequently, we demonstrated that HAP stem cells could effect nerve and spinal cord regeneration in mouse models, differentiating to Schwann cells and neurons. In previous studies, we established an efficient protocol for the differentiation of cardiac-muscle cells from mouse HAP stem cells. In the present study, we isolated the upper part of human hair follicles containing human HAP (hHAP) stem cells. The upper parts of human hair follicles were suspended in DMEM containing 10% FBS where they differentiated to cardiac-muscle cells as well as neurons, glial cells, keratinocytes and smooth-muscle cells. This method is appropriate for future use with human hair follicles to produce hHAP stem cells in sufficient quantities for future heart, nerve and spinal cord regeneration in the clinic.

Abstract
We have previously demonstrated that the neural stem-cell marker nestin is expressed in hair-follicle stem cells located in the bulge area which are termed hair-follicle-associated pluripotent (HAP) stem cells. HAP stem cells from mouse and human could form spheres in culture, termed hair spheres, which are keratin 15-negative and nestin-positive and could differentiate to neurons, glia, keratinocytes, smooth muscle cells, and melanocytes in vitro. Subsequently, we demonstrated that nestin-expressing stem cells could effect nerve and spinal cord regeneration in mouse models. Recently, we demonstrated that HAP stem cells differentiated to beating cardiac muscle cells. We recently observed that isoproterenol directs HAP stem cells to differentiate to cardiac-muscle cells in large numbers in culture compared to HAP stem cells not supplemented with isoproterenol. The addition of activin A, bone morphogenetic protein 4, and basic fibroblast growth factor, along with isoproternal, induced the cardiac muscle cells to form tissue sheets of beating heart muscle cells. In the present study, we report that, under hypoxic conditions, HAP stem cells differentiated to troponin-positive cardiac-muscle cells at a higher rate that under normoxic conditions. Hypoxia did not influence the differentiation to other cell types. For future use of HAP stem cells for cardiac muscle regeneration, hypoxia should enhance the rate of differentiation thereby providing patients more opportunities to use their own HAP stem cells which are easily accessible, for this purpose.

Abstract
We have previously discovered nestin-expressing hair-follicle-associated pluripotent (HAP) stem cells and have shown that they can differentiate to neurons, glia, and many other cell types. HAP stem cells can be used for nerve and spinal cord repair. We have recently shown the HAP stem cells can differentiate to beating heart-muscle cells and tissue sheets of beating heart-muscle cells. In the present study, we determined the efficiency of HAP stem cells from mouse vibrissa hair follicles of various ages to differentiate to beating heart-muscle cells. We observed that the whiskers located near the ear were more efficient to differentiate to cardiac-muscle cells compared to whiskers located near the nose. Differentiation to cardiac-muscle cells from HAP stem cells in cultured whiskers in 4-week-old mice was significantly greater than in 10-, 20-, and 40-week-old mice. There was a strong decrease in differentiation potential of HAP stem cells to cardiac-muscle cells by 10 weeks of age. In contrast, the differentiation potential of HAP stem cells to other cell types did not decrease with age. The possibility of rejuvenation of HAP stem cells to differentiate at high efficiency to cardiac-muscle cells is discussed.

Subsequently, we demonstrated that nestin-expressing stem cells could effect nerve and spinal cord regeneration in mouse models. In the present study, we demonstrated that HAP stem cells differentiated to beating cardiac muscle cells. We separated the mouse vibrissa hair follicle into 3 parts (upper, middle, and lower), and suspended each part separately in DMEM containing 10% FBS. All three parts of hair follicle differentiated to beating cardiac muscle cells as well as neurons, glial cells, keratinocytes and smooth muscle cells. The differentiation potential to cardiac muscle is greatest in the upper part of the follicle. The beat rate of the cardiac muscle cells was stimulated by isoproterenol and inhibited by propanolol. HAP stem cells have potential for regenerative medicine for heart disease as well as nerve and spinal cord repair.

Abstract
Hair follicles contain nestin-expressing pluripotent stem cells, the origin of which is above the bulge area, below the sebaceous gland. We have termed these cells hair follicle-associated pluripotent (HAP) stem cells. In the present study, we established efficient cryopreservation methods of the hair follicle that maintained the pluripotency of HAP stem cells. We cryopreserved the whole hair follicle from green fluorescent protein transgenic mice by slow-rate cooling in TC-Protector medium and storage in liquid nitrogen. After thawing, the upper part of the hair follicle was isolated and cultured in Dulbecco's Modified Eagle's Medium (DMEM) with fetal bovine serum (FBS). After 4 weeks of culture, cells from the upper part of the hair follicle grew out. The growing cells were transferred to DMEM/F12 without FBS. After 1 week of culture, the growing cells formed hair spheres, each containing ∼1×10(2) HAP stem cells. The hair spheres contained cells that differentiated to neurons, glial cells, and other cell types. The thawed and cultured upper part of the hair follicle produced almost as many pluripotent hair spheres as fresh follicles. The hair spheres derived from slow-cooling cryopreserved hair follicles were as pluripotent as hair spheres from fresh hair follicles. In contrast, rapid-cooling (vitrification) cryopreservation poorly preserved the pluripotency of the hair follicle stem cells. Stem cell marker genes (nestin, Sox2, and SSEA-1) were as highly expressed in slow-rate cooled cryopreserved follicles, after thawing, as in fresh follicles. However, in the vitrification cryopreserved follicles, the expression of the stem cell marker genes was greatly reduced. Direct cryopreservation of hair spheres by either the rapid-cooling, or slow-cooling method, resulted in loss of pluripotency. These results suggest that the slow-rate cooling cryopreservation of the whole hair follicle is effective to store HAP stem cells. Stored HAP stem cells would be very useful in personalized regenerative medicine, enabling any individual to maintain a bank of pluripotent stem cells for future clinical use.

Abstract
Lymph nodes are often the first target of metastatic cancer which can then remetastasize to distant organs. The progression of lymph node metastasis is dependent on sufficient blood supply provided by angiogenesis. In the present study, we have developed a color-coded imaging model to visualize angiogenesis of lymph nodes metastasis using green fluorescent protein (GFP) and red fluorescent protein (RFP). Transgenic mice carrying GFP under the control of the nestin promoter (ND-GFP mice) were used as hosts. Nascent blood vessels express GFP in these mice. B16F10-RFP melanoma cells were injected into the efferent lymph vessel of the inguinal lymph node of the ND-GFP nude mice, whereby the melanoma cells trafficked to the axillary lymph node. Three days after melanoma implantation, ND-GFP-expressing nascent blood vessels were imaged in the axillary lymph nodes. Seven days after implantation, ND-GFP-expressing nascent blood vessels formed a network in the lymph nodes. ND-GFP-positive blood vessels surrounded the tumor mass by 14 days after implantation. However, by 28 days after implantation, ND-GFP expression was diminished as the blood vessels matured. Treatment with doxorubicin significantly decreased the mean nascent blood vessel length per tumor volume. These results show that the dual-color ND-GFP blood vessels/RFP-tumor model is a powerful tool to visualize and quantitate angiogenesis of metastatic lymph nodes as well as for evaluation of its inhibition.

Abstract
Currently-used rodent tumor models, including transgenic tumor models, or subcutaneously growing tumors in mice, do not sufficiently represent clinical cancer. We report here development of methods to obtain a highly clinically-accurate rectal cancer model. This model was established by intrarectal transplantation of mouse rectal cancer cells, stably expressing green fluorescent protein (GFP), followed by disrupting the epithelial cell layer of the rectal mucosa by instilling an acetic acid solution. Early-stage tumor was detected in the rectal mucosa by 6 days after transplantation. The tumor then became invasive into the submucosal tissue. The tumor incidence was 100% and mean volume (±SD) was 1232.4 ± 994.7 mm(3) at 4 weeks after transplantation detected by fluorescence imaging. Spontaneous lymph node metastasis and lung metastasis were also found approximately 4 weeks after transplantation in over 90% of mice. This rectal tumor model precisely mimics the natural history of rectal cancer and can be used to study early tumor development, metastasis, and discovery and evaluation of novel therapeutics for this treatment-resistant disease.

Abstract
The effect of UVC irradiation was investigated on a model of brain cancer and a model of experimental brain metastasis. For the brain cancer model, brain cancer cells were injected stereotactically into the brain. For the brain metastasis model, lung cancer cells were injected intra-carotidally or stereotactically. The U87 human glioma cell line was used for the brain cancer model, and the Lewis lung carcinoma (LLC) was used for the experimental brain metastasis model. Both cancer cell types were labeled with GFP in the nucleus and RFP in the cytoplasm. A craniotomy open window was used to image single cancer cells in the brain. This double labeling of the cancer cells with GFP and RFP enabled apoptosis of single cells to be imaged at the subcellular level through the craniotomy open window. UVC irradiation, beamed through the craniotomy open window, induced apoptosis in the cancer cells. UVC irradiation was effective on LLC and significantly extended survival of the mice with experimental brain metastasis. In contrast, the U87 glioma was relatively resistant to UVC irradiation. The results of this study suggest the use of UVC for treatment of superficial brain cancer or metastasis.

Abstract
Cancer cells, with and without fluorescent protein expression, were irradiated with various doses of UVC (100, 400, and 600 J/m(2)). Dual-color Lewis lung carcinoma cells (LLC) and U87 human glioma cells, expressing GFP in the nucleus and RFP in the cytoplasm and non-colored LLC and U87 cells were cultured in 96-well plates. Eight hours after seeding, the cells were irradiated with the various doses of UVC. The resulting cell number was determined after 24 hours. Compared to non-colored LLC cells, the number of dual-color LLC cells decreased significantly due to UVC irradiation with 100 J/m(2) (p=0.003). Although there was no significant difference in the number of dual-color and non-colored U87 cells after 100 J/m(2) UVC irradiation (p=0.852), the number of dual-color U87 cells decreased significantly with respect to non-colored cells due to UVC irradiation with 400 J/m(2) and 600 J/m(2) (p=0.011 and p=0.009, respectively). Thus, both dual-color LLC and dual-color U87 cells were more sensitive to UVC light than non-colored LLC and U87 cells. These results suggest that the expression of fluorescent proteins in cancer cells can enhance photodynamic therapy (PDT) using UVC and possibly with other wavelengths of light as well.

Abstract
We have previously demonstrated that the neural stem-cell marker nestin is expressed in hair follicle stem cells. Nestin-expressing cells were initially identified in the hair follicle bulge area (BA) using a transgenic mouse model in which the nestin promoter drives the green fluorescent protein (ND-GFP). The hair-follicle ND-GFP-expressing cells are keratin 15-negative and CD34-positive and could differentiate to neurons, glia, keratinocytes, smooth muscle cells and melanocytes in vitro. Subsequently, we showed that the nestin-expressing stem cells could affect nerve and spinal cord regeneration after injection in mouse models. In the present study, we separated the mouse vibrissa hair follicle into three parts (upper, middle and lower). Each part of the follicle was cultured separately in DMEM-F12 containing B-27 and 1% methylcellulose supplemented with basic FGF. After 2 mo, the nestin-expressing cells from each of the separated parts of the hair follicle proliferated and formed spheres. Upon transfer of the spheres to RPMI 1640 medium containing 10% FBS, the nestin-expressing cells in the spheres differentiated to neurons, as well as glia, keratinocytes, smooth muscle cells and melanocytes. The differentiated cells were produced by spheres which formed from nestin-expressing cells from all segments of the hair follicle. However, the differentiation potential is greatest in the upper part of the follicle. This result is consistent with trafficking of nestin-expressing cells throughout the hair follicle from the bulge area to the dermal papilla that we previously observed. The nestin-expressing cells from the upper part of the follicle produced spheres in very large amounts, which in turn differentiated to neurons and other cell types. The results of the present study demonstrate that multipotent, nestin-expressing stem cells are present throughout the hair follicle and that the upper part of the follicle can produce the stem cells in large amounts that could be used for nerve and spinal cord repair.

Abstract
Nestin-positive, keratin 15 (K15)-negative multipotent hair follicle stem cells are located above the hair follicle bulge. We have termed this location the hair follicle pluripotent stem cell area. We have previously shown that transplantation of nestin-expressing hair follicle stem cells can regenerate peripheral nerve and spinal cord injuries. In the present study, we regenerated the impinged sciatic nerve by transplanting hair follicle pluripotent stem cells. Human hair follicle stem cells were transplanted around the impinged sciatic nerve of ICR nude (nu/nu) mice. The hair follicle stem cells were transplanted between impinged sciatic nerve fragments of the mouse where they differentiated into glial fibrillary acidic protein-positive Schwann cells and promoted the recovery of pre-existing axons. The regenerated sciatic nerve functionally recovered. These multipotent hair follicle stem cells thereby provide a potential accessible, autologous source of stem cells for regeneration therapy of nerves degenerated by compression between bony or other hard surfaces.

Abstract
A 46-year-old man noticed a nodule on his sole. The nodule was removed and the specimen showed a lobular proliferation of tumor cells with glandular differentiation embedded in mucinous stroma. A diagnosis of chondroid syringoma was made. Twelve years later, he noted a swelling in the right inguinal region. The mass was surgically removed. The histopathological findings of the lymph node showed the more atypical tumor cells in the mucoid stroma. Upon reexamination, the primary tumor contained malignant chondroid syringoma (MCS) cells; the tumor cells metastasized to lymph node. MCS is rare with 43 reported cases in the literature. The site of the primary tumor was the lower extremity in 35 percent, the head in 28 percent, and the upper extremity in 23 percent. The percentage of malignant cases with local recurrence, nodal metastasis, and distant metastasis was 49 percent, 42 percent, and 40 percent, respectively. In these cases, the average time period until disease recurrence was 23 months, 50 months, and 66 months for local recurrence, nodal metastasis, and distant metastasis, respectively. Of these, 23 percent of the cases succumbed. As MCS may progress very slowly and disease recurrence including metastasis occurs in a relatively high percentage of cases, long-term follow-up of MCS cases is required.

Abstract
We have previously developed a telomerase-specific replicating adenovirus expressing GFP (OBP-401), which can selectively label tumors in vivo with GFP. Intraperitoneal (i.p.) injection of OBP-401 specifically labeled peritoneal tumors with GFP, enabling fluorescence visualization of the disseminated disease and real-time fluorescence surgical navigation. However, the technical problems with removing all cancer cells still remain, even with fluorescence-guided surgery. In this study, we report imaging of tumor recurrence after fluorescence-guided surgery of tumors labeled in vivo with the telomerase-dependent, GFP-containing adenovirus OBP-401.. Recurrent tumor nodules brightly expressed GFP, indicating that initial OBP-401-GFP labeling of peritoneal disease was genetically stable, such that proliferating residual cancer cells still express GFP. In situ tumor labeling with a genetic reporter has important advantages over antibody and other non-genetic labeling of tumors, since residual disease remains labeled during recurrence and can be further resected under fluorescence guidance.

Abstract
We have previously developed a telomerase-specific replicating adenovirus expressing GFP (OBP-401). Intraperitoneal (i.p.) injection of OBP-401 specifically labeled peritoneal tumors with GFP enabling real-time surgical navigation. However, technical difficulty of removing microscopic tumors still remains, which makes it difficult to eradicate disease completely, even after so-called complete resection. In this study we report an additional advantage of OBP-401. Weeks after surgical navigation with OBP-401, recurrent tumor nodules were observed with GFP imaging, indicating that OBP-401 treatment for peritoneal disseminated disease enabled detection of its subsequent recurrence after surgical navigation. Thus tumor labeling with a genetic reporter has important advantages over antibody and other non-genetic labeling since reminant disease remains labeled and can be further resected.

Abstract
Nestin has been shown to be expressed in the hair follicle, both in the bulge area (BA) as well as the dermal papilla (DP). Nestin-expressing stem cells of both the BA and DP have been previously shown to be pluripotent and be able to form neurons and other non-follicle cell types. The nestin-expressing pluripotent stem cells from the DP have been termed skin precursor or SKP cells. The objective of the present study was to determine the major source of nestin-expressing pluripotent stem cells in the hair follicle and to compare the ability of the nestin-expressing pluripotent stem cells from the BA and DP to repair spinal cord injury. Transgenic mice in which the nestin promoter drives GFP (ND-GFP) were used in order to observe nestin expression in the BA and DP. Nestin-expressing DP cells were found in early and middle anagen. The BA had nestin expression throughout the hair cycle and to a greater extent than the DP. The cells from both regions had very long processes extending from them as shown by two-photon confocal microscopy. Nestin-expressing stem cells from both areas differentiated into neuronal cells at high frequency in vitro. Both nestin-expressing DP and BA cells differentiated into neuronal and glial cells after transplantation to the injured spinal cord and enhanced injury repair and locomotor recovery within four weeks. Nestin-expressing pluripotent stem cells from both the BA and DP have potential for spinal cord regeneration, with the BA being the greater and more constant source.

Abstract
Melanoma cell lines that stably express green fluorescent protein (GFP) and nude mice that ubiquitously express red fluorescent protein (RFP) have previously been developed to study tumor-host interaction by color-coded imaging. In the present study, the efficacy of fluorescence-guided ultraviolet C (UVC) irradiation on the growth of murine melanoma expressing GFP in the ear of RFP mice was determined using a non-invasive ear-tumor imaging model developed previously. The GFP-expressing melanoma and RFP-expressing blood vessels from the transgenic mice expressing RFP used as hosts were readily visible using non-invasive imaging. The melanoma was treated under fluorescence guidance with UVC at 650 J/m2/minute for 3 minutes. The ears of the mice were observed before and 24 hours after irradiation with UVC. UVC inhibited melanoma growth and also damaged blood vessels in the tumor. Thus, UVC irradiation has a direct effect on melanoma growth as well as an anti-angiogenesis effect. This color-coded tumor-host model is useful for evaluation of treatment efficacy on melanoma growth and angiogenesis, which are readily discernable with non-invasive color-coded fluorescent protein imaging. These results suggest that fluorescence-guided UVC irradiation is a promising therapeutic strategy for melanoma.

Abstract
We previously showed that the stem cell marker nestin is expressed in hair follicle stem cells which suggested their pluripotency. We subsequently showed that the nestin-expressing hair-follicle pluripotent stem (hfPS) cells can differentiate in culture to neurons, glial cells, keratinocytes, and other cell types and can promote regeneration of peripheral nerve and spinal cord injuries upon injection to the injured nerve or spinal cord. The location of the hfPS cells has been termed the hfPS cell area (hfPSCA). Previously, hfPS cells were cultured for 1-2 months before transplantation to the injured nerve or spinal cord which would not be optimal for clinical application of these cells for nerve or spinal cord repair, since the patient should be treated soon after injury. In the present study, we addressed this issue by directly using the upper part of the hair follicle containing the hfPSCA, without culture, for injection into the severed sciatic nerve in mice. After injection of hfPSCA, the implanted hfPS cells grew and promoted joining of the severed nerve. The transplanted hfPS cells differentiated mostly to glial cells forming myelin sheaths, which promoted axonal growth and functional recovery of the severed nerve. These results suggest that the direct transplantation of the uncultured upper part of the hair follicle containing the hfPSA is an important method to promote the recovery of peripheral nerve injuries and has significant clinical potential.

Abstract
Using nestin-driven green fluorescent protein (ND-GFP) transgenic mice, we previously demonstrated an inter-hair-follicle blood vessel network that expresses ND-GFP and appears to originate from ND-GFP expressing hair-follicle stem cells. We report here that angiogenesis of transplanted skin or healing wounds originates from this ND-GFP-expressing microvasculature network. ND-GFP-expressing blood vessels were visualized growing from the ND-GFP-expressing hair-follicle stem cell area and re-establishing the dermal microvasculature network after skin transplantation or wound healing. When the ND-GFP stem cell area from the vibrissa (whisker) from ND-GFP mice was transplanted to transgenic mice ubiquitously expressing RFP, we observed chimeric ND-GFP-RFP blood vessels, suggesting the joining of inter-follicular blood vessel networks from the transplant and host. These observations suggest that the inter-hair-follicle blood-vessel network contributes to skin transplant survival and wound healing.

GFP-expressing splenocytes (5 × 106), derived from GFP transgenic BALB/c mice, were transplanted to BALB/c nude mice. Then, RFP-143B human osteosarcoma cells (5 × 105) were injected in a skin flap raised in these mice. The mice were treated with doxorubicin (5 mg/kg), i.p. three days in a row. The RFP-expressing 143B tumor and the GFP splenocytes accumulation around the tumor were imaged for three days. Dendritic cells (1×106), which were activated with a 143B cells lysate, were injected into the inguinal lymph node of the mice. The tumor grew gradually in the control group, whereas in the chemotherapy group, the tumor became progressively smaller. In the DC group, the tumor regressed and was almost eradicated 12 days after treatment. In the DC group, GFP splenocytes accumulated in large numbers around the tumor three days after DC treatment. The accumulation of DC cells was diminished as the tumor became smaller. In the chemotherapy group, in contrast, accumulation of splenocytes gradually increased even though the tumor became progressively smaller. Future experiments will be on syngeneic models to determine the influence of an intact immune system on the interaction of splenocytes and DC cells with cancer cells.

Abstract
Abstract
Cancer invasion of the lymphatic system and spread to draining lymph nodes is a common occurrence and is often a first step of the metastatic pathway. Suppression of tumor angiogenesis in the lymph node should inhibit cancer growth and further spread from the lymph node. In the present study, we evaluated angiogenesis inhibitors in lymph node metastasis using GFP imaging. Transgenic nude mice expressing GFP under the control of the nestin promoter (ND-GFP mice) were used as hosts. Nascent blood vessels express GFP in these mice (Cancer Res. 65, 5352-5357, 2005). B16F10-RFP mouse melanoma cells were injected into the efferent lymph vessel of the inguinal lymph node of the transgenic ND-GFP nude mice to establish experimental metastasis in the axillary lymph node. The mice were given daily i.p. injections of doxorubicin or vehicle controls at days 0, 1, and 2 after implantation of tumor cells. The axillary lymph nodes of the mice were observed at day 8 after injection of tumor cells. Angiogenesis was quantified in the tumor-involved lymph node by measuring the total length of ND-GFP nascent blood vessels. The number of ND-GFP-expressing blood vessels in the tumor-involved lymph nodes was significantly less in the doxorubicin-treated animals than in vehicle control mice. Treatment with doxorubicin significantly decreased the volume of the metastatic axillary-node tumor as well as nascent blood vessel formation. These results show the utility of the dual-color ND-GFP-mouse and RFP-cancer-cell model to visualize and quantitate angiogenesis in tumor-involved lymph nodes and to screen for angiogenesis inhibitors at this site.
