Abstract
Adipose-derived mesenchymal stem cells (ASCs) represent a valid therapeutic option for clinical application in several diseases, due to their ability to repair damaged tissues and to mitigate the inflammatory/immune response. A better understanding of the underlying mechanisms regulating ASC biology might represent the chance to modulate their in vitro characteristics and differentiation potential for regenerative medicine purposes. Herein, we investigated the effects of the demethylating agent 5-azacytidine (5-aza) on proliferation, clonogenicity, migration, adipogenic differentiation and senescence of ASCs, to identify the molecular pathways involved. Through functional assays, we observed a detrimental effect of 5-aza on ASC self-renewal capacity and migration, accompanied by actin cytoskeleton reorganization, with decreased stress fibers. Conversely, 5-aza treatment enhanced ASC adipogenic differentiation, as assessed by lipid accumulation and expression of lineage-specific markers. We analyzed the involvement of the Akt/mTOR, MAPK and Wnt/β-catenin pathways in these processes. Our results indicated impairment of Akt and ERK phosphorylation, potentially explaining the reduced cell proliferation and migration. We observed a 5-aza-mediated inhibition of the Wnt signaling pathway, this potentially explaining the pro-adipogenic effect of the drug. Finally, 5-aza treatment significantly induced ASC senescence, through upregulation of the p53/p21 axis. Our data may have important translational implications, by helping in clarifying the potential risks and advantages of using epigenetic treatment to improve ASC characteristics for cell-based clinical approaches.

Abstract
Background Alopecia areata (AA) spares the stem cell compartment and attacks only the base of the hair follicle, which is surrounded by infiltrating lymphocytes. AA is associated with polymorphisms in immune-related genes and with decreased function of CD4+CD25+ T regulatory (Treg) cells. Treg function is modulated by the costimulatory molecules, like inducible costimulator (ICOS) that are crucial in orienting T cell differentiation and function so that they strongly impact on the immunologic decision between tolerance or autoimmunity development. Objective The aim of our study was to investigate the possible association of AA with single-nucleotide polymorphisms (SNP) present in the ICOS 3'-untranslated region (3'UTR) region and to elucidate how SNPs modulate ICOS gene expression by affecting miRNA binding sites. Methods This is a case-control study performed in 184 patients with AA and 200 controls. ICOS gene and miRNA expression were analyzed by real-time polymerase chain reaction. Results The genotype carrying the rs4404254(C) [p = 0.012, OR (95% CI): 0.5 (0.3-0.8)] and rs4675379(C) [p = 0.015, OR (95% CI): 0.3 (0.1-0.8)] 3' UTR alleles was more frequently observed in AA patients than in controls and correlated with a reduced ICOS expression. miR-1276 significantly suppressed ICOS expression by binding to the 3'UTR of ICOS mRNA. Also, we observed that, miR-101 and miR-27b are upregulated, while miR-103 and miR-2355-3p are downregulated in peripheral blood mononuclear cells of AA patients compared to controls. Conclusion Our data show that rs4404254 and rs4675379 SNPs of ICOS gene are associated with AA and also reveal that the presence of rs4404254 polymorphism correlates with ICOS post-transcriptional repression by microRNA binding.

Abstract
OBJECTIVE Evaluating sexual function and quality of life (QoL) in patients treated with a modified Abbé-McIndoe technique using in vitro cultured autologous vaginal mucosa. DESIGN Descriptive study. SETTING Policlinico Umberto I, Sapienza University of Rome. POPULATION From 2006 to 2016, 39 women affected by Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) underwent vaginoplasty at our centre using a modified Abbé-McIndoe technique with in vitro cultured autologous vaginal tissue. METHODS For each patient, vaginal tissue was obtained by full-thickness biopsy of the vaginal vestibule. Following enzymatic dissociation, cells were cultured for 2-3 weeks before the transplant. MAIN OUTCOME MEASURES Each patient completed two validated questionnaires to quantify sexual function and QoL: the Female Sexual Function Index (FSFI), administered at 12, 36, and 60 months, and the Psychological General Well Being Index (PGWBI) administered at 0, 6, and 36 months after surgery. RESULTS Twelve months after surgery, 29 patients were engaging in regular sexual activity. The FSFI test results showed a satisfactory sexual function compared to the general population, with median values of 25.85 (range 4.6-30.5) at 12 months, 27.2 (range 4.4-33.6) at 36 months, and 29.6 (range 23.9-33.6) at 60 months. The PGWBI questionnaire showed a median score of 420.5 (range 108-540) before surgery, and 459 (range 252-533) at the 60-month follow-up. CONCLUSIONS Vaginoplasty performed with the use of autologous vaginal tissue, besides ensuring a long-term satisfying sex life, helps in achieving an improvement in QoL that is maintained over time. TWEETABLE ABSTRACT Vaginoplasty using in vitro vaginal tissue ensures a satisfactory sexual function and improves quality of life.

Abstract
Hepatitis C virus (HCV) infection is a leading cause of liver fibrosis, especially in developing countries. The process is characterized by the excess accumulation of ECM that may lead, over time, to hepatic cirrhosis, liver failure and also to hepatocarcinoma. The direct role of HCV in promoting fibroblasts trans-differentiation into myofibroblasts, the major fibrogenic cells, has not been fully clarified. In this study, we found that HCV derived from HCV-infected patients infected and directly induced the trans-differentiation of human primary fibroblasts into myofibroblasts, promoting fibrogenesis. This effect correlated with the activation of GLI2, one of the targets of Hedgehog signaling pathway previously reported to be involved in myofibroblast generation. Moreover, GLI2 activation by HCV correlated with a reduction of autophagy in fibroblasts, that may further promoted fibrosis. GLI2 inhibition by Gant 61 counteracted the pro-fibrotic effects and autophagy inhibition mediated by HCV, suggesting that targeting HH/GLI2 pathway might represent a promising strategy to reduce the HCV-induced fibrosis.

Abstract
INTRODUCTION We evaluated analytical and clinical performances of IgG and IgM anticardiolipin (aCL) antibodies and anti-β2-glycoprotein I (a-β2GpI) antibodies and upper limit reference ranges (99th percentiles) in comparison with manufacturer's cutoff values with different commercial methods. METHODS We assayed aCL and a-β2GpI in serum samples from 30 healthy individuals, 77 patients with antiphospholipid syndrome (APS) diagnosed according to the Sydney criteria, 51 patients with autoimmune diseases, eight patients with previous thrombotic events, six patients with other diseases, and 18 patients with infectious diseases, using ELISA Inova Diagnostics; EliA Phadia Laboratory Systems; CliA Zenit-RA; and CliA Bio-Flash. RESULTS Anticardiolipin and a-β2GpI IgG and IgM immunoassays showed good analytic performances with both 99th percentile and manufacturer's cutoff reference values. Our results showed fair to moderate agreement among assays. In-house cutoff values gave significantly better performances only for a-β2GpI IgG with all the immunoassays analyzed with the exception of Inova CliA Bio-Flash where we obtained the same performances with in-house and manufacturer's cutoffs. CONCLUSIONS By guidelines, all laboratories are strongly advised to validate/verify the manufacturer's cutoff values. We recommend establishing low-positive, medium-/high-positive, and high-positive CliA IgG aCL and a-β2GpI ranges in order to help clinicians in the diagnosis and treatment of APS.

Abstract
Laboratory tests for anticardiolipin antibodies (aCL) and anti-β2glycoprotein I antibodies (a-β2GPI) face problems common to many autoantibody assays: the lack of a reference standard and the need for each laboratory to assess assay-specific cut-off values. The aims of the study were to evaluate the reference range upper limits (99th percentile) used for aCL and a-β2GPI in the northwest of Italy and to investigate the analytical performances of these assays with the newly obtained reference ranges. We assayed aCL and a-β2GPI in 104 serum samples from patients without a history of thrombosis, pregnancy morbidity, tumours, infections and/or autoimmune diseases (30 males and 74 non-pregnant females). We tested all the commercial assays available in our regions (i.e. Orgentec Diagnostika, Aesku Diagnostics and Inova Diagnostics ELISA; CliA Zenit-RA and EliA Phadia Laboratory Systems). A further 30 serum samples, including 10 from healthy subjects, 10 from antiphospholipid syndrome (APS) patients and 10 from septic patients were assessed to investigate the analytical performance of the obtained cut-off limits. Reference range upper limits obtained with the commercial kits differ among assays and from the values reported by the manufacturer. Moreover, normal reference ranges calculated for IgG and IgM aCL differed from the arbitrary selected laboratory classification values suggested in the guidelines of 40 GPL and MPL.

Abstract
BACKGROUND Buckwheat allergy is a rare food allergy in Europe and North America, whereas it is often described and studied in Asia. The aim of this study was to describe a series of patients with proven buckwheat allergy evaluated in an Italian allergy clinic. Co-sensitization to other food and inhalant allergens and immunoblotting profiles of buckwheat-allergic patients were studied. METHODS Patients with suspected buckwheat allergy who attended the allergy clinic between January 1, 2006, and September 30, 2008, were evaluated. All patients underwent skin prick tests for a standard panel of inhalant and food allergens, prick-by-prick with buckwheat flour, buckwheat-specific IgE determinations, and double-blind placebo-controlled food challenge (DBPCFC) with buckwheat flour. Immunoblotting with buckwheat flour extract was performed on sera from buckwheat-allergic patients. RESULTS Among 72 patients with suspected buckwheat allergy, 30 (41.7%) were sensitized to buckwheat and 24 had a positive DBPCFC. The mean buckwheat IgE level was 6.23 kUA/l (range, 0.16 to >100 kUA/l). Several IgE-binding proteins were identified and grouped into three patterns: a 16-kDa band in patients with predominantly gastrointestinal symptoms with grass and wheat flour co-sensitization, a 25-kDa band in patients with predominantly cutaneous symptoms and a low frequency of co-sensitization, and a 40-kDa band in patients with anaphylaxis and a low frequency of co-sensitization. CONCLUSIONS Buckwheat allergy is an emerging food allergy in Italy. We identified three distinct patterns of clinical and laboratory characteristics, suggesting that specific allergens could be more frequently associated with clinical manifestations of different severity.

Multiple intestinal atresia is a rare disorder with vascular or hereditary etiology. So far, the occurrence of this malformation along with omphalocele has not been reported. We describe a boy born from a nonconsanguineous gypsy couple with intrauterine growth retardation, omphalocele, and multiple intestinal atresia from the pylorus to the rectum. The microscopic examination of the intestine shows multiple small lumina with a sieve-like appearance. This is characteristic of the hereditary atresias and suggests development of a defect in (re)canalization during embryogenesis. The association with omphalocele indicates a common developmental defect may be present.

Abstract
Fibroblast growth factor 10 is a novel member of the fibroblast growth factor family, which is involved in morphogenesis and epithelial proliferation. It is highly homologous to the keratinocyte growth factor (or fibroblast growth factor 7), a key mediator of keratinocyte growth and differentiation. Both fibroblast growth factor 10 and keratinocyte growth factor bind with high affinity to the tyrosine kinase keratinocyte growth factor receptor. Here we analyzed the effect of fibroblast growth factor 10 on primary cultures of human keratinocytes, grown in chemically defined medium, and we compared the proliferative and differentiative cell responses to fibroblast growth factor 10 with those induced by keratinocyte growth factor and epidermal growth factor. Cell counting, 5-bromo-2'-deoxyuridine incorporation, and western blot analysis showed that fibroblast growth factor 10, similarly to keratinocyte growth factor, not only is a potent mitogen for human keratinocytes, but also promotes the expression of both early differentiation markers K1 and K10 and late differentiation marker filaggrin in response to the Ca2+ signal, and seems to sustain the proliferative activity in suprabasal stratified cells. Immunoprecipitation/western blot analysis revealed that fibroblast growth factor 10, similarly to keratinocyte growth factor, is able to induce tyrosine phosphorylation of keratinocyte growth factor receptor and of cellular substrates such as PLCgamma.

Abstract
Keratinocyte growth factor (KGF) is involved in the control of proliferation and differentiation of human keratinocytes. It binds to, and activates, the tyrosine kinase KGF receptor (KGFR), a splicing transcript variant of the fibroblast growth factor receptor 2. We have previously shown (C. Marchese et al., Cell Growth Differ., 8: 989-997, 1997) that differentiation of primary cultured keratinocytes triggered by high Ca2+ concentrations in the growing medium induced up-regulation of KGFR expression, which suggested that KGFR may play a crucial role in the control of the proliferative/differentiative program during transition from basal to suprabasal cells. Here we analyzed the process of modulation of the expression of KGFRs in the human keratinocyte cell line HaCaT, widely used as a model to study keratinocyte differentiation. Western blot and double immunofluorescence for KGFR and the K1 differentiation marker showed that cell differentiation and stratification induced by confluence and high cell density correlated with an increase in KGFR expression. KGFRs, present on suprabasal differentiated cells, appeared to be efficiently tyrosine-phosphorylated by KGF, which indicated that the receptors up-regulated by differentiation can be functionally activated by ligand binding. Bromodeoxyuridine incorporation assay revealed that a significant portion of suprabasal differentiated cells expressing KGFR seemed to be still able to synthesize DNA and to proliferate in response to KGF, which suggested that increased KGFR expression may be required for retention of the proliferative activity.

Abstract
Autonomic and electroencephalographic (EEG) responses to aversive stimuli presented by means of hypnotic suggestion have been studied in man.Healthy volunteers with simple phobia were screened for susceptibility to hypnosis. The experimental paradigm included periods of rest during which the hypnotized subjects were asked to produce an emotionally neutral mental image and periods of emotional activation in which they were asked to image a phobic object. Heart rate (HR), respiratory frequency (RF) and EEG were processed to obtain the HR-related indexes of sympatho-vagal balance and the EEG spectral components. The results showed a significant increase in HR and RF with a shift of the sympatho-vagal indexes towards a sympathetic predominance during the hypnotic emotional activation. EEG activity showed a significant increase in the gamma band with a left fronto-central prevalence. There was also a less pronounced increase in the beta band. In conclusion, by means of hypnosis, autonomic and behavioral responses to fear-like stimuli can be induced in man in a reproducible and controlled manner. Such a paradigm could be applied in human neuroimaging studies to identify central nervous structures that modulate stress and fear-related reactions.

Abstract
Cultured human melanocytes express mGlu5 metabotropic glutamate (mGlu) receptors, as shown by RT-PCR, immunocytochemistry, Western blot analysis, and measurement of agonist-stimulated polyphosphoinositide hydrolysis. The mGlu5 receptor agonists (S)-3, 5-dihydroxyphenylglycine and quisqualate increased [(3)H-methyl]thymidine incorporation and melanocyte proliferation in subconfluent cultures, but impaired cell viability in confluent cultures. Both effects were prevented by 2-methyl-6-(2-phenyl-1-ethynyl)-pyridine, a potent and highly selective mGlu5 receptor antagonist. Agonists of other mGlu receptor subtypes (such as the mGlu2/3 receptor agonist, 2S,2'R,3'R-2-2', 3'-dicarboxycyclopropylglycine, or the mGlu4/6/7/8 receptor agonist, L-2-amino-4-phosphonobutanoate) or selective agonists of ionotropic glutamate receptors (N-methyl-D-aspartate, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate, and kainate) did not affect melanocyte proliferation or viability. The presence of a receptor for glutamate, the major excitatory neurotransmitter, in human melanocytes is intriguing. mGlu5 receptors may be involved in the control of melanocyte proliferation (and perhaps in other functions), but harbor a potential toxicity and may therefore contribute to cell damage under pathological conditions.

Abstract
Patients with Peutz-Jeghers' syndrome (PJS) develop hamartomatous gastrointestinal polyps and characteristic pigmentation, as a result of germline mutations in the LKB1 gene. The hamartomas in PJS were long considered to be without malignant potential. There is, however, accumulating epidemiological evidence to suggest that PJS predisposes to cancers at several different sites (colon, pancreas, breast, ovary, testis, and cervix), although large enough patient samples are rarely available to prove this. Allelic imbalance [allele loss, loss of heterozygosity (LOH)] has previously been reported in a small number of PJS polyps, suggesting that LKB1 acts as a tumour suppressor in these tumours. This study confirms allelic loss at LKB1 in PJS polyps and shows that LOH also occurs in cancers of the colon, breast, and cervix in PJS patients. Allele loss was additionally found in a colonic adenoma from a PJS patient, strongly suggesting the existence of a hamartoma-(adenoma)-carcinoma sequence in tumourigenesis. These results provide molecular evidence that PJS patients are predisposed to cancers at several sites, as a direct result of selection for loss of the 'wild-type' LKB1 allele in tumours. Given the rare involvement of LKB1 in sporadic cancers, these data also suggest that the indirect effect on cancer risk (or 'bystander effect') proposed for hamartomas in juvenile polyposis does not apply to carcinomas in PJS.

Abstract
Immunohistochemical analysis of the expression of keratinocyte growth factor receptor (KGFR) was performed in human endometrial carcinomas from 18 patients and in normal proliferative and secretory endometrium. The level of immunostaining was correlated with the clinico-pathological characteristics of the endometrial carcinoma patients and with the parallel expression of the epidermal growth factor receptor (EGFR) and erbB-2. The results showed that KGFR expression increased with the stage of the tumor and that the simultaneous overexpression of the three growth factor receptors appeared to be related to the depth of myometrial invasion. Taken together, these observations suggest that KGFR may represent an additional prognostic indicator in endometrial cancer.

Abstract
Keratinocyte growth factor (KGF) is a fibroblast growth factor which acts specifically on epithelial cells, regulating their proliferation and differentiation. KGF elicits its activity through binding to and activation of KGF receptor, a splicing transcript variant of fibroblast growth factor receptor 2 (FGFR2). Here we analyzed the pathway of internalization of KGF and its receptor using several approaches, including the utilization in immunofluorescence and in immunoelectron microscopy of a functional KGF-HFc chimeric protein as a specific tool to follow the endocytosis of the growth factor and of its receptor. Western blot analysis with anti-FGFR2 and anti-phosphotyrosine antibodies, as well as parallel double immunofluorescence and confocal analysis of NIH3T3 KGFR transfectants treated with KGF at 4 degrees C, followed by incubations at 37 degrees C for different time points, showed that KGF induced endocytosis of tyrosine activated KGFRs. The use of KGF-HFc in immunofluorescence and in immunogold electron microscopy on KGFR transfectants, A253 epithelial tumor cells and human cultured keratinocytes allowed us to follow the early steps of KGF internalization and revealed that this process occurred through clathrin-coated pits. A quantitative ELISA assay confirmed that KGF-HFc binding on the cell surface rapidly decreased because of internalization. Our results demonstrate that KGF is internalized by receptor-mediated endocytosis and illustrate the involvement of clathrin-coated pits in this process.

Abstract
In the present study, we used five different polymorphic markers to construct the haplotype at the adenomatous polyposis coli (APC) locus in families with familial adenomatous polyposis (FAP) and in the normal Italian population. Non-ambiguous haplotypes were reconstructed from 246 normal chromosomes and 65 FAP chromosomes. In the control population, the four polymorphisms intragenic to APC gave rise to 16 haplotypes, the most common of which (II and XV) accounted for over 50% of all chromosomes. In FAP patients, 13 haplotypes were found but their distribution was not statistically different from normal subjects. Eighty complete chromosomal haplotypes (many fewer than the theoretical maximum of 208) for the five polymorphic sites assayed were observed in the control population, 35 being found in the FAP patients. We compared the distribution of these haplotypes within the two groups; no statistically significant differences between normal and FAP chromosomes were found. The elevated heterogeneity of FAP chromosomes was clearly confirmed by the observation that 19 patients who carried one or other of the two most common APC mutations (nt 3183 and nt 3927) showed 18 different haplotypes. On the basis of these results, we were not able to identify a founder FAP chromosome. Various mechanisms are presented to explain this observation.

Abstract
A locus for Peutz-Jeghers syndrome (PJS) was recently mapped to chromosome 19p13.3. Each of 12 families studied was compatible with linkage to the marker D19S886. We have analysed 20 further families and found that the majority of these are consistent with a PJS gene on 19p13.3. Three families were, however, unlinked to 19p13.3 and none of the available PJS polyps from these families showed allele loss at D19S886. There were no obvious clinicopathological or ethnic differences between the 19p13.3 linked and unlinked families. There appears, therefore, to be a major PJS locus on chromosome 19p13.3 and the possibility exists of a minor locus (or loci) elsewhere.

Abstract
Keratinocyte growth factor (KGF) belongs to the fibroblast growth factor (FGF) family, and its activity seems to be restricted to epithelial cells. It elicits its biological effects through binding to the KGF receptor (KGFR), a splicing transcript variant of FGF receptor 2 (FGFR2). The presence of multiple isoforms of FGFR2 and the overlapping specificities of the FGFs with respect to their receptors do not allow the use of anti-FGFR antibodies as specific immunocytochemical tools. Here we used a chimeric protein recently obtained by the fusion of KGF to the HFc portion of immunoglobulin G (La Rochelle et al., J. Cell Biol., 129: 357-366, 1995) to analyze the expression and distribution of KGFRs in human keratinocytes cultured in chemically defined medium and incubated with different Ca2+ concentrations to modulate their differentiation. We observed at both immunofluorescence and electron microscopic levels and by Western blot analysis of proliferation (K6) or differentiation (K1) markers that KGFR expression is up-modulated during keratinocyte differentiation. Cytofluorimetric and Western blot analysis revealed that exposure to the high Ca2+ differentiation signal resulted in a significant increase in KGFRs. RNase protection assay using a KGFR-specific cDNA probe demonstrated that this effect was correlated with a > 4-fold increase in KGFR transcript level. Our results suggest that the expression of KGFR, unlike that of the epidermal growth factor receptor, may control the proliferative-differentiative program from basal to suprabasal cells in human skin.

Abstract
We investigated the expression and distribution of keratinocyte growth factor (KGF) (FGF-7) and its receptor (KGFR) during reepithelialization of human skin. KGF mRNA levels increased rapidly by 8-10-fold and remained elevated for several days. In contrast, KGFR transcript levels decreased early but were significantly elevated by 8-9 d. A KGF-immunoglobulin G fusion protein (KGF-HFc), which specifically and sensitively detects the KGFR, localized the receptor to differentiating keratinocytes of control epidermis, but revealed a striking decrease in receptor protein expression during the intermediate period of reepithelization. Suramin, which blocked KGF binding and stripped already bound KGF from its receptor, failed to unmask KGFRs in tissue sections from the intermediate phase of wound repair. The absence of KGFR protein despite increased KGFR transcript levels implies functional receptor downregulation in the presence of increased KGF. This temporal modulation of KGF and KGFRs provides strong evidence for the functional involvement of KGF in human skin reepithelialization.

Abstract
The authors present the results of a retrospective study aimed at identifying the most common neoplastic associations diagnosed in urology. Between 1991-94 430 patients with neoplasia of the urogenital tract were diagnosed and studied: 50 (11.6%) showed a second primary neoplasia (48 cases dual, 2 cases triple). The long-term results show that the most frequent neoplastic associations were, in order of greatest incidence, those involving the gastrointestinal, respiratory and hemolymphatic regions. In 30 patients the second neoplasia became manifest within 5 years of the first, whereas neoplasias of the uterus and adnexa or breast have a late onset. An oncological familial pattern was observed in 14 cases, but it was not easy to analyse the clinical significance. The genetic interpretation of each individual neoplastic association is still complex and difficult to evaluate. Biomolecular research may in the future be able to provide some of the vital data for a correct etiopathogenetic classification.

Abstract
Fibroblast growth factor receptors (FGFRs) are encoded by at least four distinct highly conserved genes, and alternative splicing generates multiple gene products. The close relationship among different FGFRs has greatly increased the difficulty in generating specific immunochemical probes. As an alternative strategy, we constructed a fusion protein comprising keratinocyte growth factor (KGF) and an IgG1 Fc domain (HFc). The chimeric molecule was efficiently secreted from transfectants as a disulfide-linked dimer that bound KGFRs with high affinity. Moreover, the KGF-HFc, like native KGF, induced DNA synthesis by epithelial cells implying normal functional receptor activation. Because it retained the convenient detection properties of an immunoglobulin, it was possible to use the KGF-HFc in ligand-mediated histochemical analysis of KGFRs. Flow cytometry revealed KGF-HFc chimera detection of the KGFR, an alternative FGFR2 product, but not FGFR1 (flg) or FGFR2 (bek). Histochemical analysis of normal skin demonstrated the specific localization of KGFRs within the spinous layer, a zone of epithelial cell differentiation. KGFRs were also localized to epithelial cells within a specific region of the hair follicle, and they were not detectable in cells of the sweat gland. Tissue sections of soft palate and tonsil, two examples of nonkeratinizing epithelium, revealed staining of stratum spinosum and some staining of the basal cell layer as well. Neither salivary gland epithelium nor lymphoid cells were positive. The ciliated epithelium of the trachea exhibited KGFR expression in intermediate and basal cell layers. In striking contrast to the normal pattern of staining in the adjacent epithelium, a squamous cell carcinoma of skin lacked detectable KGFRs. Our present findings suggest that growth factor-Ig fusion proteins may be generally applicable in ligand-mediated histochemical detection and localization of growth factor receptors.

Abstract
BACKGROUND Cultures of epidermal cells are commonly used to study skin biology and differentiation. Recently a method to culture nail matrix cells has been established. OBJECTIVE We report the biologic characteristics of nail matrix cells in vitro compared with those of epidermal keratinocytes. METHODS Human nail matrix cells were isolated and cultured in defined medium. Electron-microscopic examination, growth rate, integrin expression and keratin synthesis pattern were evaluated. In addition, the cells were cultured in serum-containing medium. RESULTS Nail matrix cells appear to be larger than human epidermal keratinocytes and, at the ultrastructural level, they contain a higher euchromatin/heterochromatin ratio and a lower nucleus/cytoplasm ratio and have a higher growth rate. The synthesis of "hard" keratins was detected at all calcium concentrations. Immunofluorescence analyses showed the expression of alpha 2, alpha 3, and alpha 6 integrin subunits. When cultured in serum-containing medium, nail matrix cells produced an outgrowth of epithelium and a spontaneous migration phenomenon associated with a tendency to stratify in a semilunar area that resembles the architecture of the nail matrix. The pluristratified epithelium showed characteristic markers of nail differentiation. CONCLUSION Culture of nail matrix cells may represent a useful model to study the biologic properties of nail structure, alterations in some nail diseases and the effects of drugs.

Abstract
By screening patients with autosomal dominant retinitis pigmentosa for mutations in the rhodopsin gene, two deletions (8 bp and 1 bp) have been identified in exon 5; these deletions cause a shift in the reading frame. The predicted proteins should be radically altered with translation continuing past the normal stop signal and resulting in a rhodopsin molecule that is, respectively, 1 and 10 amino acids longer. The clinical phenotype of the patients is described and is compared with that associated with other mutations in the same region of the gene.

Abstract
In an investigation of the role of keratinocytes in the pre-immunological phase of contact allergy, we have studied the effect of paraphenylenediamine (PPD) on cell proliferation, membrane lipid peroxidation and the expression of the intercellular adhesion molecule 1 (ICAM-1). Because PPD undergoes rapid autoxidation in the culture medium, the effect of PPD-modified medium on keratinocyte proliferation and ICAM-1 expression was also examined. PPD at low concentrations (up to 10 micrograms/ml) and with low exposure times (0.5 h) enhanced keratinocyte proliferation, but at high concentrations and with longer exposure times resulted in cell stasis and toxicity. These effects and the enhanced membrane lipid peroxidation that was also observed can be ascribed to the production of superoxide and hydrogen peroxide by the autoxidation of PPD in the medium. At non-cytotoxic concentrations, PPD induced ICAM-1 expression on the keratinocytes. PPD-modified medium was also cytotoxic to the keratinocytes and induced ICAM-1 expression in non-cytotoxic concentrations. It appeared that superoxide and hydrogen peroxide were not responsible for the cytotoxicity. These results are consistent with the view that oxidative stress may be an essential part of the pre-immunological phase in the induction of allergic contact dermatitis.

Abstract
Investigations of the pathways regulating normal growth of epithelial cells have revealed the existence of two major growth-factor signaling cascades required for proliferation. One pathway is activated by IGF-1 or high insulin concentration. The other is triggered by EGF, TGF alpha, or members of the FGF family, including the recently discovered epithelial-cell-specific growth factor, designated keratinocyte growth factor (KGF). Its expression pattern in vivo suggests that KGF plays an important normal physiologic role as a stromal effector of epithelial cell proliferation. Oncogenes, which represent constitutively activated forms of genes critically involved in growth-factor signaling pathways, specifically abrogate the requirement for mitogens of the EGF pathway. Examples of such genes include the erbB/EGF receptor and erbB-2, which encode structurally related receptor proteins and are often amplified and/or overexpressed in epithelial malignancies. Employing reduced stringency hybridization with v-erbB as a probe, we recently identified a third member of this receptor family, designated erbB-3. cDNA cloning revealed a predicted 148-kD transmembrane polypeptide with structural features similar to those of the EGF receptor. Normal erbB-3 expression in keratinocytes and glandular epithelium suggests its physiologic role in these cell types. Moreover, markedly elevated erbB-3 mRNA levels in certain mammary tumor cell lines suggest that increased erbB-3 expression may also play a role in some human epithelial malignancies.

Abstract
Human keratinocyte growth factor (KGF) is an epithelial cell specific mitogen which is secreted by normal stromal fibroblasts. In the present studies, we demonstrate that KGF is as potent as EGF in stimulating proliferation of primary or secondary human keratinocytes in tissue culture. Exposure of KGF- or EGF-stimulated keratinocytes to 1.0 mM calcium, an inducer of differentiation, led to cessation of cell growth. However, immunologic analysis of early and late markers of terminal differentiation, K1 and filaggrin, respectively, revealed striking differences in keratinocytes propagated in the presence of these growth factors. With KGF, the differentiation response was associated with expression of both markers whereas their appearance was retarded or blocked by EGF. TGF alpha, which also interacts with the EGF receptor, gave a similar response to that observed with EGF. These findings functionally distinguish KGF from the EGF family and support the role of KGF in the normal proliferation and differentiation of human epithelial cells.

Abstract
A T-lymphoma cell line was established from a lymph node biopsy of a boy currently alive in complete remission. Neoplastic cells from this biopsy did not grow in vitro, whereas they formed a progressively growing s.c. tumor in splenectomized and sublethally irradiated nude mice and became serially transplantable in splenectomized and sublethally irradiated nude mice with a stable latency time. After the fourth transplant, cells were stored in liquid nitrogen and referred to as ST-4 cells. ST-4 cells display a membrane phenotype and a karyotype similar to that of the biopsy cells. After thawing, ST-4 cells grow both in splenectomized and sublethally irradiated nude mice and in vitro. They do not secrete interferon or interleukin 2, do not have natural killer activity, and do not respond to mitogen or alloantigen stimulation. The stable features of these T-lymphoma cells and the availability of normal autologous lymphocytes from the patient make this in vivo system quite unique and of importance for studies in tumor immunotherapy.

Abstract
Cases of familial arrhythmogenic right ventricular dysplasia (ARVD) have been reported by many authors, and a genetic mechanism of transmission has been hypothesized. Both autosomal dominant and autosomal recessive mechanism of inheritance were suggest. We present a father and a daughter affected by arrhythmogenic right ventricular dysplasia, belonging to a family with many cases of sudden death. Both of them presented with an episode of ventricular tachycardia with left bundle branch block. The clinical diagnosis was made according to electrocardiographic, echocardiographic, angionuclear and hemodynamic criteria of ARVD. The familia analysis suggest an autosomal dominant mechanism of transmission.

Abstract
Six cases of cystic hygromas detected during second trimester ultrasound examination are reported: 4 fetuses (67 per cent) had a 45, X karyotype, 1 fetus had trisomy 18, 1 fetus had a normal karyotype (46,XX) and at autopsy multiple anomalies were observed. In the latter case the family history suggested an autosomal recessive pattern of inheritance. In order to reach a definite diagnosis and give proper genetic counselling when a fetus is found to have cystic hygroma, a fetal karyotype as well as a family and reproductive history should be obtained.
