Abstract
The concept of "stem cell pathology" is to establish the role of the stem cells by exploring their contribution to lesion development. The somatic stem cells are present in the body. Malignant fibrous histiocytoma (MFH; recently named "undifferentiated pleomorphic sarcoma") includes pluripotential undifferentiated mesenchymal stem cells as a cell element. An antibody (A3) generated by using rat MFH cells as the antigen labels somatic stem cells such as bone marrow stem cells and immature endothelial cells and pericytes, as well as immature epithelial cells in epithelialization. By using A3 and other antibodies recognizing somatic stem cells, it is considered that myofibroblasts appearing in rat fibrotic lesions are developed partly from immature hepatic stellate cells in hepatic fibrosis, immature pancreatic stellate cells in pancreatic fibrosis, pericytes/endothelial cells in neovascularization in injured tissues, as well as via the epithelial-mesenchymal transition. These progenitors may be in the stem cell lineage. In this review, the author introduces the histogenesis of MFH and the characteristics of myofibroblasts appearing in fibrosis, based mainly on the author's studies.

Abstract
Lesions of D-galactosamine (D-GalN)-induced hepatotoxicity resemble those of human acute viral hepatitis. This study investigated hepatic mesenchymal cells including hepatic stellate cells (HSCs) and myofibroblasts in D-GalN-induced hepatotoxicity. Rats, injected with D-GalN (800 mg/kg body weight, once, intraperitoneally) were examined on post single injection (PSI) at 8 hours and days 1 to 5. Lesions consisting of hepatocyte necrosis and reparative fibrosis were present diffusely or focally within the hepatic lobules on PSI days 1 and 2, and then the injury recovered on PSI days 3 and 5. Myofibroblasts expressing vimentin, desmin, and α-smooth muscle actin (α-SMA) were present in the lesions. Double immunofluorescence showed that myofibroblasts reacted simultaneously to vimentin/α-SMA, desmin/α-SMA, and desmin/vimentin; furthermore, myofibroblasts reacting to vimentin, desmin, and α-SMA also co-expressed glial fibrillary acidic protein (GFAP), a marker of HSCs. Additionally, GFAP-expressing myofibroblasts reacted to nestin and A3 (both are markers of immature mesenchymal cells). Cells reacting to Thy-1, a marker for immature mesenchymal cells, also appeared in fibrotic lesions. In agreement with the myofibroblastic appearance, mRNAs of fibrosis-related factors (TGF-β1, PDGF-β, TNF-α, Timp2, and Mmp2) increased mainly on PSI days 1 and 2. Myofibroblasts with expression of various cytoskeletal proteins were present in diffuse or focal hepatic lesions, and they might be derived partly from immature HSCs and from immature mesenchymal cells.

Abstract
A monoclonal antibody (A3) was generated by using rat malignant fibrous histiocytoma (MFH) cells as the antigen. Generally, MFH is considered to be a sarcoma derived from undifferentiated mesenchymal cells. Molecular biological analyses using the lysate of rat MFH cells revealed that A3 is a conformation specific antibody recognizing both N-glycan and peptide. A3-labeled cells in bone marrow were regarded as somatic stem cells, because the cells partly coexpressed CD90 and CD105 (both immature mesenchymal markers). In the hair follicle cycle, particularly the anagen, the immature epithelial cells (suprabasal cells) near the bulge and some immature mesenchymal cells in the disassembling dermal papilla and regenerating connective tissue sheath/hair papilla reacted to A3. In the cutaneous wound-healing process, A3-labeled epithelial cells participated in re-epithelialization in the wound bed, and apparently, the labeled cells were derived from the hair bulge; in addition, A3-labeled immature mesenchymal cells in the connective tissue sheath of hair follicles at the wound edge showed the expansion of the A3 immunolabeling. A3-labeled immature epithelial and mesenchymal cells contributed to morphogenesis in the hair cycle and tissue repair after a cutaneous wound. A3 could become a unique antibody to identify somatic stem cells capable of differentiating both epithelial and mesenchymal cells in rat tissues.

Abstract
A3, generated as a monoclonal antibody against rat malignant fibrous histiocytoma cells, recognizes somatic stem cells in rats. We analyzed the distribution of A3-positive cells in dextran sulfate sodium (DSS)-induced colonic lesions consisting of regenerating mucosa and fibrosis. Male 6-week-old F344 rats were administered 5% DSS in drinking water for 5 to 7 days, and lesions at recovery stage were also examined. In untreated control adult colons, A3-positive cells are localized around the crypts where stem cell niche is formed. Histopathologically, in colons of DSS-administered rats, mucosal atrophy, inflammatory cell infiltration, and fibrosis were observed in the lamina propria; thereafter, mucosal epithelia were desquamated, and crypts were decreased gradually with decrease in surrounding A3-positive cells. At the early recovery stage, crypts showed regeneration with reappearance of A3-positive cells. Interestingly, A3-positive cells aggregated in desquamated mucosa surface of fibrosis. Aggregated A3-positive cells coexpressed with vimentin, Thy-1, and partly CK19 but did not react simultaneously with α-SMA. Likely, aggregated A3-positive cells may be rescue cells with nature of both mesenchymal and epithelial cells to maintain self-renewal after injury in the colon. A3 antibody would become a useful tool to investigate the participation of stem cells in rat colonic lesions.

Abstract
Mesenchymal stem cells (MSCs) are previously found to have potential capacity to differentiate into osteocytes when exposed to specific stimuli. However, the detailed molecular mechanism during this progress remains largely unknown. In the current study, we characterized the lncRNA NKILA as a crucial positive regulator for osteogenesis of MSCs. NKILA attenuation significantly inhibits the calcium deposition and alkaline phosphatase activity of MSCs. More interestingly, we defined that NKILA is functionally involved in the regulation of RXFP1/PI3K‐AKT and NF‐κB signalling. Knockdown of NKILA dramatically down‐regulates the expression of RXFP1 and then reduces the activity of AKT, a downstream regulator of RXFP1 signalling which is widely accepted as an activator of osteogenesis. Moreover, we identify NF‐κB as another critical regulator implicated in NKILA‐mediated osteogenic differentiation. Inhibition of NF‐κB can induce the expression of RUNX2, a master transcription factor of osteogenesis, in a HDAC2‐mediated deacetylation manner. Thus, this study illustrates the regulatory function of NKILA in osteogenesis through distinct signalling pathways, therefore providing a new insight into searching for new molecular targets for bone tissue repair and regeneration.

Abstract
A3, generated as a monoclonal antibody against rat malignant fibrous histiocytoma
(MFH)-derived cloned cells, recognizes somatic stem cells (bone-marrow/hair follicle stem
cells). We investigated the distribution of cells immunoreactive to A3 in the developing
rat intestine (particularly, the colon), focusing on the ontogenic kinetics of A3-positive
cells. In the rat intestine, A3 labeled spindle-shaped stromal cells localized in the
submucosa and labeled endothelial cells of capillaries in the lamina propria forming villi
in the early development stage. With development progression, A3-positive cells were
exclusively localized around the crypts of the colon. Double immunofluorescence revealed
that A3-positive cells around the crypts reacted to vimentin (for mesenchymal cells) and
Thy-1 (for mesenchymal stromal cells) but not to α-SMA (for mesenchymal myofibroblastic
cells) or CD34 (for hematopoietic stem cells), indicating that A3-positive cells around
the crypts may have characteristics of immature mesenchymal cells. In addition, A3 labeled
a few epithelial cells at the base of colon crypts. Furthermore, immunoelectron microscopy
revealed that A3-positive cells lay inside myofibroblasts adjacent to the epithelium of
the crypts. A3-positive cells were regarded as a new type of immature mesenchymal cells
around the crypts. Collectively, A3-positive cells might take part in the stem cell niche
in the colon, which is formed through epithelial-mesenchymal interaction.

Abstract
An increasing number of studies have focused on the role of microRNAs in liver fibrosis/cirrhosis. miR-214 has recently attracted more attention as a fibrosis-related factor; however, the molecular mechanisms in hepatic fibrogenesis remain largely unknown. Here, we investigate the pathological role of miR-214 during progression of liver cirrhosis in rats. Rats were injected intraperitoneally with thioacetamide at a dose of 100 mg/kg body weight, twice a week. The liver was collected at post first injection weeks 5, 10, 15, and 20. Hepatic expression of miR-214 was analyzed by real-time polymerase chain reaction, in situ hybridization, and laser microdissection. The effects of miR-214 overexpression were investigated by in vitro transfection using fibroblastic MT-9 cells. miR-214 was highly upregulated in the fibrotic area in parallel with the cirrhosis progression. miR-214 overexpression in MT-9 cells under transforming growth factor-β1 stimulation resulted in decreased cell number and increased expression of cleaved caspase 3 and decreased expression of α-smooth muscle actin, suggesting that miR-214 induces apoptosis and inhibits myofibroblast differentiation in fibroblastic cells under stimulation of fibrogenic factors. These data indicate an anti-fibrotic role of miR-214 in chemically induced liver fibrosis/cirrhosis.

Abstract
Hepatic stellate cells, the principal fibrogenic cell type in the liver, are known to express the astrocyte marker glial fibrillary acidic protein (GFAP). However, the exact role of GFAP-expressing cells in liver fibrosis remains to be elucidated. In this study, cellular properties of GFAP-expressing cells were investigated in a rat model of liver cirrhosis. Six-week-old male F344 rats were injected intraperitoneally with thioacetamide (100 mg/kg BW, twice a week) and examined at post first injection weeks 5, 10, 15, 20 and 25. Appearance of GFAP-expressing myofibroblasts peaked at week 15, associated with fibrosis progression. The majority of GFAP-expressing myofibroblasts co-expressed vimentin, desmin and alpha-smooth muscle actin. Some GFAP-positive myofibroblasts co-expressed nestin (neural stem cell marker), while a few co-expressed A3 (mesenchymal stem cell marker) and Thy-1 (immature mesenchymal cell marker). A few GFAP expressing cells underwent both mitosis and apoptosis. These results indicate that there is a dynamic participation of GFAP-expressing myofibroblasts in rat liver cirrhosis, and that they are mainly derived from hepatic stellate cells, and partly from cells in the stem cell lineage. These findings, which were shown for the first time in detail, would be useful to understand the role of GFAP-expressing myofibroblasts in the pathogenesis of chemically induced liver cirrhosis.

Abstract
Hepatic stellate cells (HSCs), which can express glial fibrillary acidic protein (GFAP) in normal rat livers, play important roles in hepatic fibrogenesis through the conversion into myofibroblasts (MFs). Cellular properties and possible derivation of GFAP-expressing MFs were investigated in thioacetamide (TAA)-induced rat liver injury and subsequent fibrosis. Seven-week-old male F344 rats were injected with TAA (300mg/kg BW, once, intraperitoneally), and were examined on post single injection (PSI) days 1-10 by the single and double immunolabeling with MF and stem cell marker antibodies. After hepatocyte injury in the perivenular areas on PSI days 1 and 2, the fibrotic lesion consisting of MF developed at a peak on PSI day 3, and then recovered gradually by PSI day 10. MFs expressed GFAP, and also showed co-expressions such cytoskeletons (MF markers) as vimentin, desmin and α-SMA in varying degrees. Besides MFs co-expressing vimentin/desmin, desmin/α-SMA or α-SMA/vimentin, some GFAP positive MFs co-expressed with nestin or A3 (both, stem cell markers), and there were also MFs co-expressing nestin/A3. However, there were no GFAP positive MFs co-expressing RECA-1 (endothelial marker) or Thy-1 (immature mesenchymal cell marker). GFAP positive MFs showed the proliferating activity, but they did not undergo apoptosis. However, α-SMA positive MFs underwent apoptosis. These findings indicate that HSCs can proliferate and then convert into MFs with co-expressing various cytoskeletons for MF markers, and that the converted MFs may be derived partly from the stem cell lineage. Additionally, well-differentiated MFs expressing α-SMA may disappear by apoptosis for healing. These findings shed some light on the pathogenesis of chemically induced hepatic fibrosis.

Abstract
Cellular characteristics of myofibroblasts and its possible origin with mesenchymal stem cell nature in scleroderma remain to be investigated. We analyzed these cells in scleroderma induced in F344 rats by bleomycin (BLM) by immunolabeling using a panel of marker antibodies for cytoskeletons (vimentin, desmin, α-smooth muscle actin (α-SMA)) and stromal stem cells (Thy-1, A3). Skin samples were collected at 1, 2, 3, and 4 weeks after initiation of subcutaneous injections of BLM (100 μl of 1 mg/ml, daily). In double immunofluorescence, myofibroblasts reacting simultaneously to α-SMA, vimentin, and Thy-1 were seen in sclerotic lesions with a time-dependent increase. Mesenchymal cells in the perifollicular dermal sheath (PDS) displayed increased reactivity for Thy-1 and vimentin, but α-SMA expression did not increase in these cells. In double immunofluorescence, both myofibroblasts and pericytes in newly formed blood vessels in sclerotic lesions co-expressed α-SMA, vimentin and Thy-1, and the PDS cells and pericytes reacted simultaneously to A3, Thy-1 and vimentin. Desmin-positive cells were infrequently seen around the blood vessels. Based on these findings, the PDS cells and pericytes may be involved as possible progenitors of myofibroblasts in sclerotic lesions in the stromal stem cell lineage. Interestingly, increased number of TUNEL-positive apoptotic epithelial cells in the atrophied hair follicles significantly correlated with increase in immunohistochemical scoring of vimentin and Thy-1 in the PDS. Apoptosis in the hair follicle might have mediate the perifollicular fibrosis, resulting in extensive scleroderma. The present findings would provide new insights in the pathogenesis of BLM-induced scleroderma in terms of myofibroblasts and its origin.

Abstract
We present a case of malignant fibrous histiocytoma located in the region of the temple that corresponded to the main site of a traumatic hematoma. There are reports of malignant transformation triggered by different kinds of wounds, but the malignant transformation in a subcutaneous hematoma is rare. For chronic expanding hematoma, magnetic resonance imaging or biopsy is recommended in determining whether it is malignant, especially when the mass is growing rapidly.

Abstract
PURPOSE Bone marrow adherent cells contain conventional bone marrow stromal cells and mesenchymal stem cells and these cells constitute the hematopoietic microenvironment. Mesenchymal stem cells have the capacity to give rise to multiple mesenchymal lineage cells and even ectodermal lineage cells. In the present study, we investigated what types of tumor cells are inducible from BM adherent cells by chemical carcinogens. METHODS Bone marrow cells from neonatal C3H/HeN mice were collected within 24 h after birth and then cultured. Four days later, bone marrow adherent cells were obtained and the cells were treated with 3-methylcholanthrene. RESULTS By this treatment, some transformed clones consisting of large spindle cells were obtained. The transformed cells were highly positive for CD44 and were positive for Sca-1, CD49d and CD106, whereas the cells were negative for hematolymphoid markers. The cell clones had the ability to support hematopoiesis in vitro. These results indicate that the transformed cell lines have the characteristics of BM stromal cells/mesenchymal stem cells. Moreover, during culture of the transformed cells, spontaneous bone nodule formation was observed. When the transformed cells were inoculated into immunodeficient mice subcutaneously, the neoplasms grew in the subcutaneous tissue of the mice. Microscopically and ultrastructurally, the neoplasms showed the typical morphology of undifferentiated high-grade pleomorphic sarcoma (UHGPS). Bone-related genes have been found to be expressed in both transformed cells and UHGPSs. CONCLUSION The present study suggests that UHGPSs are derived from BM stromal cells, probably mesenchymal stem cells.

Abstract
The essence and origin of malignant fibrous histiocytoma (MFH) have been debated for now close to five decades. Originally characterized as a morphologically unique soft-tissue sarcoma subtype of unclear etiology in 1963, with a following 15 years of research only to conclude that "the issue of histogenesis [of MFH] is largely unresolvable"; it is "now regarded as synonymous with [high grade] undifferentiated pleomorphic sarcoma and essentially represents a diagnosis of exclusion". Yet despite this apparent lack of progress, the first decade of the 21st century has seen some significant progress in terms of defining the origins of MFH. Perhaps more importantly these origins might also pave the way for novel therapies. This manuscript will highlight MFH's troubled history, discuss recent advances, and comment as to what the coming years may promise and what further needs to be done to make sure that progress continues.
