Abstract
Background: The therapeutic strategy of invasive breast cancer is based on routine histopathological markers (estrogen-, progesterone receptor, HER2, Ki67) routinely evaluated in tumor cells. However, the assessment of cancer stroma could influence therapeutic strategies. Studies have shown that stromal expression of CD10, a zinc-dependent metalloproteinase, is associated with biological aggressiveness of the tumor. In the present retrospective study, we aimed to evaluate stromal CD10 expression and association between CD10 expression and response to neoadjuvant chemotherapy in invasive breast cancer. Methods: CD10 immunohistochemistry was performed on core biopsies taken before the neoadjuvant therapy. Stromal CD10 expression was determined and compared with well-known predictive and prognostic tissue markers as well as with the following groups defined according to the degree of tumor response: no regression, partial regression, and complete regression. Results: A total of 60 locally advanced invasive breast carcinomas of "no special type" were included. The proportion of CD10 positive tumors was significantly higher in the "no regression" group compared to "complete regression" group (p = 0.000). Stromal CD10 expression was found to be significantly associated with decrease in response to neoadjuvant chemotherapy. According to CD10 expression we did not find any difference in hormone receptor status, Ki67, tumor grade or neostromal area. Conclusion: Our data suggest that CD10 expression can serve as a predictive marker of the effect of neoadjuvant chemotherapy in breast cancer patients. Therefore, its inclusion into the routine assessment of biopsies to tailor tumor-specific therapeutic strategies merits consideration.

Abstract
Intrahepatic bile ducts transport bile between bile canaliculi and the extrahepatic bile duct. The luminal surface of this tract is lined by a layer of biliary epithelial cells, or cholangiocytes, which secrete mucins consisting of scaffold proteins and O-glycosidically linked carbohydrate side chains. Although mucin core proteins have been extensively investigated, the structure and function of carbohydrate side chains have not. Here, we demonstrate that distinct sulfated glycans positive for MECA-79, R-10G, and 297-11A, but not 5D4, monoclonal antibodies are expressed in the cytoplasm of cells of large-sized ducts and in the apical membrane of cells in ductules, and that R-10G immunolabeling is partially eliminated by endo-β-galactosidase digestion, supporting the presence of N-acetylglucosamine-6-O-sulfated N-acetyllactosamine structures. We observed comparable apical membrane-predominant staining in ductular reactions seen during regeneration that occurs in various liver diseases and in cholangiolocarcinoma, a subtype of small duct-type intrahepatic cholangiocarcinoma (iCCA). Apical membrane expression of distinct sulfated glycans in large duct-type iCCA was negligible. Intriguingly, under pathological conditions, endo-β-galactosidase digestion almost completely eliminated R-10G immunoreactivity. These findings suggest that apical membrane expression of distinct sulfated glycans is a characteristic feature of ductules and their reactive and neoplastic counterparts.

Abstract
Complications arising from infection with the carcinogenic liver fluke Opisthorchis viverrini cause substantial morbidity and mortality in Thailand and adjacent lower Mekong countries. In parallel, the incidence rate of diabetes mellitus (DM) is increasing in this same region, and indeed worldwide. Many residents in opisthorchiasis-endemic regions also exhibit DM, but the hepatobiliary disease arising during the co-occurrence of these two conditions remains to be characterized. Here, the histopathological profile during co-occurrence of opisthorchiasis and DM was investigated in a rodent model of human opisthorchiasis in which diabetes was induced with streptozotocin. The effects of excretory/secretory products from the liver fluke, O. viverrini (OVES) on hepatocyte and cholangiocyte responses during hyperglycemic conditions also were monitored. Both the liver fluke-infected hamsters (OV group) and hamsters with DM lost weight compared to control hamsters. Weight loss was even more marked in the hamsters with both opisthorchiasis and DM (OD group). Hypertrophy of hepatocytes, altered biliary canaliculi, and biliary hyperplasia were more prominent in the OD group, compared with OV and DM groups. Profound oxidative DNA damage, evidenced by 8-oxo-2'-deoxyguanosine, proliferating cell nuclear antigen, and periductal fibrosis characterized the OD compared to OV and DM hamsters. Upregulation of expression of cytokines in response to infection and impairment of the pathway for insulin receptor substrate (IRS)/phosphatidylinositol-3-kinases (PI3K)/protein kinase B (AKT) signaling attended these changes. In vitro, OVES and glucose provoked time- and dose-dependent effects on the proliferation of both hepatocytes and cholangiocytes. In overview, the co-occurrence of opisthorchiasis and diabetes exacerbated pathophysiological damage to the hepatobiliary tract. We speculate that opisthorchiasis and diabetes together aggravate hepatobiliary pathogenesis through an IRS/PI3K/AKT-independent pathway.

Abstract
Background Previous investigations have indicated that CD10 is associated with biological aggressivity in human cancers, but the use of this marker for diagnosis and prognosis is more complex. The aim of this study was to evaluate the expression of CD10 in breast cancer and its association with the clinicopathological features. In addition, we investigated whether a relationship exists between CD10 expression and cancer stem cells. Methods CD10 expression was examined by the immunohistochemistry in a series of 133 invasive breast carcinoma cases. Results were correlated to several clinicopathological parameters. Cancer stem cell phenotype was assessed by the immunohistochemical analysis of CD44 and ALDH1. Results Significant CD10 expression was found in the fusiform stromal cells in 19.5% of the cases and in the neoplastic cells in 7% of the cases. The stromal CD10 positivity was more frequently found in tumors with lymph node metastasis (p = 0.01) and a high histological grade (p = 0.01). However, CD10 expression by the neoplastic cells correlates with a high histological grade (p = 0.03) and the absence of estrogen (p = 0.002) as well as progesterone (p = 0.001) receptor expression. We also found that CD10 expression by the stromal cells, but not by the neoplastic cells, correlates significantly with the expression of cancer stem cell markers (CD44+/ALDH1+) (p = 0.002). Conclusion These findings support the role of the stromal CD10 expression in breast cancer progression and dissemination, and suggest a relationship with cancer stem cells.

Abstract
This study clarified the role of Cygb, the fourth globin in mammals originally discovered in rat hepatic stellate cells (HSCs), in cholestatic liver disease. Bile duct ligation (BDL) augmented inflammatory reactions as revealed by increased infiltrating neutrophils, CD68+-macrophages, and chemokine expression in Cygb-/- mice. In these mice, impairment of bile canalicular indicated by the loss of CD10 expression, down-regulation of bile salt transporters, increased total bile acid, and massive apoptotic and necrotic hepatocytes occurred with the release of cytochrome c, activation of caspase 3, resulting in reduced animal survival compared to wild-type mice. In Cygb-/- mouse liver, all of NO metabolites and oxidative stress were increased. Treatment with NO inhibitor restrained all above phenotypes and restored CD10 expression in BDL Cygb-/- mice, while administration of NO donor aggravated liver damage in BDL-wild type mice to the same extent of BDL-Cygb-/- mice. N-acetylcysteine administration had a negligible effect in all groups. In mice of BDL for 1-3 weeks, expression of all fibrosis-related markers was significantly increased in Cygb-/- mice compared with wild-type mice. Thus, Cygb deficiency in HSCs enhances hepatocyte damage and inflammation in early phase and fibrosis development in late phase in mice subjected to BDL, presumably via altered NO metabolism.

Abstract
The human CD10 antigen is a single pass, type II transmembrane, 100 kD cell surface glycoprotein belonging to peptidase M13 family. Identified in common acute lymphoblastic leukemia as a cancer specific antigen, CD10 is a cell surface ectoenzyme widely expressed on different types of cells. Earlier, it was used only as a cell surface marker to identify and differentiate between haematological malignancies. Later, reported to be present in various malignancies, it is thought to play significant role in cancer development and progression. Regulated expression of CD10 is necessary for angiogenesis and so forth. However its expression level is found to be deregulated in different cancers. In some cancers, it acts as tumor suppressor and inhibits tumor progression whereas in others it has tumor promoting tendency. However, its role in tumorigenesis remains unclear. This review summarises structural features, functions, and probable role of CD10 in cancer development.

Abstract
It has been shown that the liver of immunodeficient mice can be efficiently repopulated with human hepatocytes when subjected to chronic hepatocellular damage. Mice with such chimeric livers represent useful reagents for medical and clinical studies. However all previously reported models of humanized livers are difficult to implement as they involve cross-breeding of immunodeficient mice with mice exhibiting genetic alterations causing sustained hepatic injury. In this paper we attempted to create chimeric livers by inducing persistent hepatocellular damage in immunodeficient Rag2(-/-) γc(-/-) mice using an adenovirus encoding herpes virus thymidine kinase (AdTk) and two consecutive doses of ganciclovir (GCV). We found that this treatment resulted in hepatocellular damage persisting for at least 10 weeks and enabled efficient engraftment and proliferation within the liver of either human or allogenic hepatocytes. Interestingly, while the nodules generated from the transplanted mouse hepatocytes were well vascularized, the human hepatocytes experienced progressive depolarization and exhibited reduced numbers of murine endothelial cells inside the nodules. In conclusion, AdTk/GCV-induced liver damage licenses the liver of immunodeficient mice for allogenic and xenogenic hepatocyte repopulation. This approach represents a simple alternative strategy for chimeric liver generation using immunodeficient mice without additional genetic manipulation of the germ line.

Diagnostic utility of CD10 in benign and malignant extrahepatic bile duct lesions. Am J Surg Pathol 2012; 36:101-8.

Abstract
CD10, a cell surface enzyme with neutral metalloendopeptidase activity, is a marker for intestinal epithelial brush border. It is also present in normal bile ducts and gallbladder epithelia but is absent in cholangiocarcinomas. However, the expression profile of CD10 in benign and malignant extrahepatic biliary lesions has not been studied. In this study, 69 biopsies, 9 resections, and 9 cell blocks prepared from fine-needle aspirations of the extrahepatic bile ducts from 86 patients were studied immunohistochemically for CD10 expression. The majority of cases contained normal biliary epithelium (NL, n=64), along with foci of benign or malignant lesions in various combinations. Benign lesions included reactive atypia (n=35), low-grade dysplasia of unknown significance (n=21), and bile duct adenoma (BDA, n=1). Malignant lesions included high-grade dysplasia (HGD, n=45) and invasive adenocarcinoma (IC, n=30). As expected, the NL showed strong continuous staining at the apical surface in all cases. Benign lesions were also CD10 positive in all but 3 cases; however, the staining pattern was discontinuous, with positive cells varying from 20% to 80%. None of the malignant lesions showed CD10 immunoreactivity, except for 2 HGD cases and 1 IC case, which exhibited focal staining. The Pearson χ2 and Fisher exact tests showed significant statistical difference in CD10 expression among the study groups (P<0.001). Our findings suggest that absence of CD10 expression in strips of atypical biliary epithelial cells may be a phenotype associated with malignant transformation and may serve as a useful marker to aid in the evaluation of bile duct biopsies, in which distinction between benign and malignant lesions on biopsies or cytology specimens can be extremely challenging because of limited sampling, crush artifact, and frequent inflammatory/reactive changes.

Abstract
UNLABELLED Liver transplantation (LT) is a unique model to study hepatitis C virus (HCV) entry into hepatocytes. Recent in vitro studies suggest significant changes in the expression of the HCV receptors claudin-1 and occludin after HCV infection. Our aims were: (1) to characterize claudin-1 and occludin expression in grafts from LT recipients and (2) to explore their potential influence on early HCV kinetics and their changes after HCV infection. We included 42 HCV-infected LT recipients and 19 uninfected controls. Claudin-1 and occludin were detected in paraffin-embedded liver biopsies obtained during reperfusion and 3 and 12 months after LT. HCV receptors were characterized by confocal immunofluorescence microscopy; quantification and colocalization studies were performed with dedicated software. Claudin-1 and occludin expression were restricted to the apical pole of hepatocytes. There was a significant correlation between the amount of scavenger receptor B1 at the time of reperfusion and the HCV-RNA decay during the first 24 hours following LT (r = 0.55, P = 0.007). Similarly, there was a significant correlation between the levels of claudin and occludin and the slope of HCV-RNA increase during the first week after LT (r = 0.63, P = 0.005). Occludin and claudin-1 levels increased significantly 12 months after LT (P = 0.03 and P = 0.007, respectively). The expression pattern of both proteins, however, remained unchanged, colocalizing strongly (60%-94%) at the apical membrane of hepatocytes. CONCLUSIONS HCV receptor levels at the time of LT seem to modulate early HCV kinetics. Hepatitis C recurrence after LT was associated with increased levels of claudin-1 and occludin in the hepatocyte cell membrane, although it did not alter their localization within the tight junctions.

Abstract
Background CD10 antigen is a 100-kDa-cell surface zinc metalloendopeptidase and it is expressed in a variety of normal and neoplastic lymphoid and nonlymphoid tissues. The aim of this study was to evaluate CD10 expression in urothelial carcinoma of the urinary bladder and to determine the correlation between immunohistochemical (IHC) CD10 expression and histopathologic parameters including grade and stage. Methods 371 cases of urothelial bladder carcinomas, all from transurethral resections, were included in this study. Hematoxylin-eosin (HE) stained sections from each case were reevaluated histopathologically according to WHO 2004 grading system. The TNM system was used for pathologic staging. Selected slides were also studied by IHC and a semiquantitative scoring for CD10 expression based on the percentage of positive cells was performed. Results 157 cases (42.3%) showed immunostaining while 214 cases (57.7%) were negative for CD10. 1+ staining was seen in 65 CD10 positive cases (41.4%), and 2+ in 92 cases (58.6%). Overall CD10 expression as well as 2+ immunostaining was significantly correlated with high histologic grade. Overall CD10 expression was also significantly higher in invasive pT1 and pT2-3 tumors compared to noninvasive pTa tumors. pT1 and pT2-3 tumors were also significantly correlated with 2+ immunostaining. Conclusion To date, only a few comparative IHC studies have assessed CD10 expression in urothelial carcinoma of the urinary bladder and this study represents the largest series. Our findings indicate that CD10 expression is strongly correlated with high tumor grade and stage in urothelial carcinoma of the bladder, and that CD10 may be associated with tumor progression in bladder cancer pathogenesis.

Abstract
CONTEXT Dermatopathology covers a large variety of entities, some having very similar histologic appearances. Immunohistochemistry is an incredibly helpful tool that is useful in diagnosis as well as prognosis of selected skin tumors. OBJECTIVE To provide a comprehensive review of recent trends and immunohistochemical stains used by dermatopathologists. Emphasis is placed on new stains as well as novel uses of existing stains. DATA SOURCES All data were gathered from published journal articles available through the National Center for Biotechnology Information PubMed database. CONCLUSIONS New immunohistochemical targets are continually being found, contributing to more accurate diagnosis and classification of skin tumors. The presence of specific markers can be used to determine the aggressiveness of malignancies and design treatment strategies. In addition, application of existing stains can help determine intravascular spread of malignancy in primary cutaneous lesions. And use of rapid immunohistochemical staining techniques on frozen sections can assist in more complete excision of tumor margins. Immunohistochemistry is a highly versatile and growing tool of dermatopathologists.

Abstract
BACKGROUND To describe sequential changes in Merkel cells (MC), and CD10(+) and CD34(+) stromal cells (SC) during the transition from benign to malignant oral lesions and correlate with clinicopathologic parameters. MATERIALS AND METHODS Changes in cytokeratin 20-positive (CK20(+)) Merkel cells, CD10(+) and CD34(+) SC were immunohistochemically examined in specimens of 28 oral verrucous carcinomas (VC), 32 squamous cell carcinomas (SCC) and 36 benign squamous lesions (BSL). Immunoreactivity and localized inflammation were measured quantitatively and/or semiquantitatively, and between-group results were statistically compared. RESULTS The mean number of CD34(+) SC was significantly lower in VC (57.36) and SCC (33.81) than BSL (351.56, P < 0.001). However, the three tumor types had similar staining level and number of CD10(+) SC. We found a significant difference in the density of MC between BSL and VC (P < 0.001) or SCC (P < 0.001). The number of CK20(+) MC was significantly lower in highly inflamed specimens than mildly inflamed specimens (P = 0.001). CONCLUSION CD34(+) SC and to a lesser extent MC, but not CD10(+) SC, reveal statistically different density during the transition from benign to malignant oral lesions. The correlations between the CD34(+) SC expression and squamous lesions may be associated with epithelial dysplasia and/or tumor invasion.

Abstract
Many tissues, including hepatobiliary cells, express neutral endopeptidase (CD10), encoded by MME. Serum neutral endopeptidase activity (NEA) has been recommended as a marker of cholestasis in adults but not in children with Alagille syndrome (AGS). We investigated ontogenic and disease-related differences in the expression of CD10. CD10 was found on canalicular surfaces of hepatocytes throughout the lobule in 16 adults and in 31 children aged > or =24 months, with and without cholestasis, but not in 39 children aged <24 months, with and without cholestasis. Ten AGS children aged 2 months to 6 years lacked any canalicular CD10 expression. Cholangiocyte apices and/or intrasinusoidal granulocytes marked for CD10 in all subjects. Liver membrane fractions from a child with cholestasis aged <24 months and from 2 AGS patients aged >24 months contained reduced levels of CD10. In contrast, AGS children and all controls expressed CD10 similarly on granulocytes. MME mRNA was found in the liver of children aged <24 months and of adults, all with cholestasis, and of AGS patients. Granulocyte MME mRNA levels were similar among all study subjects; however, liver MME mRNA levels were 6- to 140-fold less than in normal adults in all cholestatic subjects, including AGS children. Methylation of the MME promoter was not detected in the liver of AGS children. In conclusion, hepatocytes in early childhood physiologically lack immunohistochemically detectable CD10. Reduced MME mRNA in AGS is not due to MME promoter methylation. Liver CD10 in childhood appears to undergo reduced synthesis or rapid degradation, which persists in AGS. Absence of CD10 expression thus may limit NEA as a marker of cholestasis in young patients and in AGS.

Abstract
BACKGROUND Trichoepithelioma (TE) is a benign neoplasm that shares both clinical and histologic features with basal cell carcinoma (BCC). However, it is important to distinguish these neoplasms. Limited immunohistochemical stains are available to separate these two tumors. METHODS CD10 protein immunohistochemistry was performed on paraffin-embedded biopsies of 13 TE and 23 BCC diagnosed by routine microscopy. Cases were analyzed for pattern of CD10 expression by tumor cells and surrounding stroma. RESULTS Twelve of 13 (92%) TE showed positive stromal immunoreactivity. Of these, eight cases also demonstrated positivity of the papilla, and two also showed positivity of the basaloid cells. No TE demonstrated epithelial expression alone. On the other hand, expression of CD10 by basaloid cells was identified in 20 (87%) cases of BCC. Stromal positivity was also identified in three cases of BCC. Condensation of CD10-positive stromal cells around basaloid nests was statistically significant in differentiating TE from BCC (p < 0.0001). Conversely, CD10-positive basaloid cells were seen predominantly in BCC (p < 0.0001). CONCLUSIONS This study demonstrates a statistically significant difference in CD10 staining pattern between TE and BCC. Thus, CD10 may be a useful adjunct marker in distinguishing these tumors.

Abstract
AIMS This study was prompted by published observations concerning the absence of normal bile canalicular CD10 staining in some cases of primary liver cell carcinoma. Our aim was to investigate the possibility that this loss of staining occurs prior to the development of cancer. METHODS AND RESULTS The study comprised 164 liver biopsies, including 96 from patients with hepatitis C infection of various grades and stages including nine cases with cirrhosis, 24 other cases of cirrhosis of other aetiology, five cases of primary liver carcinoma, 12 cases of metastatic carcinoma, as well as biopsies with a variety of other liver diseases. CD10 was demonstrated in paraffin sections using the avidin-biotin immunoperoxidase technique. In hepatitis C cases, a significant loss of the canalicular pattern was seen in four out of 41 (10%) biopsies with stages 0-1 compared with 25 out of 55 (45%) with stages 2-6 (P < 0.001). There was also a significant difference (P < 0.001) between biopsies with stage 2-3 and those with stage 4-6, where marked pattern loss was seen in 9/37 (24%) and 16/18 (89%), respectively. Marked loss of the pattern was also seen in 16 out of the 24 (67%) other cirrhotic biopsies, as well as in cases with severe lobular inflammation and cholestasis and liver cell dysplasia and carcinoma. In hepatitis C biopsies, no relationship was noted between the reduction in the canalicular pattern and the necroinflammatory score. CONCLUSIONS CD10-stained bile canalicular pattern in liver biopsies is preserved in cases with mild fibrosis and inflammation, but it becomes increasingly reduced with the advance of fibrosis or the presence of severe lobular inflammation or extensive metastases. Further investigations into the relationship between the changes in CD10 staining pattern and liver function tests may be useful in explaining test results.

Abstract
Differentiating primary and metastatic hepatic malignancies can be diagnostically challenging in fine-needle aspiration cytology (FNAC). We compared four immunohistochemical (IHC) markers, pCEA, CD10, HepPar1, and CD34, in differentiating hepatocellular carcinoma (HCC) from metastatic carcinoma (MC) in FNAC specimens. Sixty cases of liver FNAC with their corresponding cell blocks were retrieved from the hospital computer system, including 30 HCC and 30 MC (15 colon, 10 breast, and 5 pancreas). The diagnoses were confirmed by clinical follow-up and surgical resection or core needle biopsy. The direct cytologic smears were air-dried and Diff-Quik-stained, and alcohol-fixed and Papanicolaou-stained. Cell block sections from the aspirates were immunostained for pCEA, CD10, HepPar1, and CD34. IHC on cytologic smears for HCC was performed on 10 cases and compared with the cell block results. In HCC, CD10, and pCEA demonstrated the characteristic canalicular staining in 23/30 (77%) and 24/30 (80%) of the cases, respectively; however, none of the MC showed a canalicular staining pattern. HepPar1 was positive in 26/30 (87%) of the HCC cases and one MC. CD34 stained sinusoidal endothelial cells in 27/30 (90%) cases of HCC and six MC. Our results demonstrate that the canalicular staining pattern for CD10 and sinusoidal staining pattern of CD34 are very specific, in addition to the high specificity and sensitivity of HepPar1 for HCC. Cell blocks were more informative in demonstrating the characteristic architecture and immunostaining pattern of the malignancy than the cytologic smears. An IHC panel consisting of pCEA, CD10, HepPar1, and CD34 is useful for confirming HCC in FNAC of the liver.

Abstract
Several tetraspanins bind directly to a few molecular partners to form primary complexes, which might assemble through tetraspanin-tetraspanin interactions to form a network of molecular interactions, the tetraspanin web. We have produced a monoclonal antibody directed to a 63 kDa molecule (determined under non-reducing conditions) associated with CD9. This molecule was first identified by MS as a molecule with four Ig domains, EWI-2. Like the related molecule CD9P-1, EWI-2 was found to be a partner not only for CD9, but also for CD81, a tetraspanin required for hepatic infection by the parasite responsible for malaria, and also a putative hepatitis C virus receptor. Using chimaeric CD9/CD82 molecules, two separate regions of CD9 of 40 and 47 amino acids were demonstrated to confer the ability to interact with EWI-2. Both EWI-2 and CD9P-1 were detected in the human liver at the surface of hepatocytes and were found to associate with CD81 on freshly isolated hepatocytes. EWI-2 also co-localized with CD81 in the liver. CD9P-1 was not detected on most peripheral blood cells, whereas EWI-2 was expressed on the majority of B-, T- and natural killer cells and was not detected on monocytes, polynuclear cells or platelets. This distribution is identical to that of CD81. Finally, EWI-2 associated with all tetraspanins studied after lysis under conditions preserving tetraspanin-tetraspanin interactions, showing that EWI-2 is a new component of the tetraspanin web.

Abstract
Microvillous inclusion disease (MID) is a specific disorder of the intestinal brush border that leads to intractable secretory diarrhea in infants. At present, electron microscopic analysis is required for its definitive diagnosis. However, this technique is not always available or feasible, and the diagnostic microvillous inclusions may not be evident in all specimens. Accordingly, the availability of a panel of histochemical and immunohistochemical stains displaying a specific staining pattern for MID will allow pathologists to reach a definitive diagnosis of this disorder without recourse to electron microscopy. CD10 is a membrane-associated neutral peptidase, shown to have a linear brush-border staining pattern in normal small intestine. We studied the staining pattern of CD10 in small intestinal biopsies from six patients with MID and in 24 control cases (10 normal small intestine, 10 celiac disease, two autoimmune enteropathy, and two allergic enteropathy). All MID cases revealed prominent cytoplasmic CD10 immunoreactivity in surface enterocytes. In contrast, all control cases showed linear brush-border staining. Similar results were obtained with periodic acid-Schiff, polyclonal carcinoembryonic antigen, and alkaline phosphatase, three stains known to show cytoplasmic staining of surface enterocytes in MID. In conclusion, CD10 is a valuable tool for the diagnosis of MID. It may be used as part of a panel that includes other stains with a distinctive staining pattern in MID such as periodic acid-Schiff, polyclonal carcinoembryonic antigen, and alkaline phosphatase. We suggest that the definitive diagnosis of MID can be reached when small bowel biopsies from infants with intractable diarrhea display cytoplasmic staining of surface enterocytes with the above-mentioned stains.

Abstract
Neprilysin (CD10) is expressed in both normal and neoplastic liver tissue, where it exhibits a characteristic canalicular pattern (CD10can) similar to the one observed when antibodies cross-react with biliary glycoprotein I (p-CEA). The aim of this retrospective study was to investigate the use of CD10can in differentiating between hepatocellular carcinomas (HCCs; 63 specimens) and nonhepatocellular carcinomas (non-HCCs) metastatic to the liver (non-HCC; 25 specimens). Immunostaining was performed with antibodies directed against CD10, p-CEA, and alpha-fetoprotein (AFP). Albumin mRNA was detected by nonradioactive in situ hybridization (ISHalbumin). In the HCC group a canalicular staining pattern for CD10 was found in 43 (68.3%) specimens. AFP was found in 15 (23.8%) specimens, and a canalicular staining pattern for p-CEA was present in 60 (95.2%) specimens. ISHalbumin was performed in 35 HCC specimens and showed labeling of tumor cells in 30 (85.7%) specimens. In the non-HCC group, CD10can, and p-CEA, immunostaining for AFP and labeling for ISHalbumin were confined to non-neoplastic liver tissue. Sensitivity and specificity were, respectively, 68.3% and 100% for CD10can, 23.8% and 100% for AFP, 95.2% and 100% for canalicular p-CEA, and 86.4% and 100% for ISHalbumin. Our results demonstrate that canalicular staining for CD10 is a highly specific marker of hepatocytic differentiation. Although it does not differentiate between benign and malignant lesions, CD10can is clearly useful in differentiating between HCC and non-HCC.

Abstract
AbstractThis study shows that human postthymic T cells express CD10 when undergoing apoptosis, irrespective of the signal responsible for initiating the apoptotic process. Cells from continuous T-cell lines did not normally express CD10, but became CD10+ when induced into apoptosis by human immunodeficiency virus (HIV) infection and exposure to CD95 monoclonal antibody, etoposide, or staurosporin. Inhibitors of caspases blocked apoptosis and CD10 expression. Both CD4+ and CD8+ T cells purified from normal peripheral blood expressed CD10 on apoptotic induction. CD10 was newly synthesized by the apoptosing cells because its expression was inhibited by exposure to cycloheximide and CD10 mRNA became detectable by reverse transcription-polymerase chain reaction in T cells cultured under conditions favoring apoptosis. To show CD10 on T cells apoptosing in vivo, lymph node and peripheral blood T cells from HIV+ subjects were used. These suspensions were composed of a substantial, although variable, proportion of apoptosing T cells that consistently expressed CD10. In contrast, CD10+ as well as spontaneously apoptosing T cells were virtually absent in peripheral blood from normal individuals. Collectively, these observations indicate that CD10 may represent a reliable marker for identifying and isolating apoptosing T cells in vitro and ex vivo and possibly suggest novel functions for surface CD10 in the apoptotic process of lymphoid cells.

Abstract
Hepatoblastoma is an embryonal tumour of the liver, which often contains tissue components with multidirectional differentiation. The occurrence of cell surface antigens in this tumour has not been studied systematically, and we therefore investigated 20 hepatoblastomas for the expression of common acute lymphoblastic leukaemia antigen (CALLA) and cell adhesion molecules (CAMs) in their different tissue components. Epithelial tumour cells of fetal differentiation contained E-cadherin. This protein did not occur in tumour areas with embryonal or mesenchymal differentiation. In contrast, immature embryonal and anaplastic cells expressed CALLA and the hyaluronate receptor (HCAM, CD44). Both fetal and embryonal areas stained irregularly positive for ICAM-1, which, in contrast, was not present on anaplastic cells. Immature fibrous tissue did not contain any of these molecules except for ICAM-1. However, some cells adjacent to, or enclosed in, osteoid were positive for HCAM and NCAM. Like small undifferentiated hepatoblastoma cells, primitive mesenchymal spindle-shaped cells also expressed CALLA, HCAM, and the polysialylated embryonic form of NCAM strongly. This last is not present on other epithelial or mesenchymal tumour cells. Hepatoblastoma cells of varying differentiation express distinct patterns of CAMs and CALLA. Our results give further insight into their histogenesis and cellular interactions and may explain their variable ability for invasive growth and formation of metastases.
