Cheresh, University of California at San Diego, La Jolla, CA, and accepted by the Editorial Board May 6, 2011 (received for review January18, 2011)Pancreatic ductal adenocarcinoma (PDAC) is a fatal disease withpoor patient outcome often resulting from late diagnosis in advancedstages. To date methods to diagnose early-stage PDACare limited and in <strong>vivo</strong> detection of pancreatic intraepithelial neoplasia(PanIN), a preinvasive precursor of PDAC, is impossible.Using a cathepsin-activatable near-infrared probe in combinationwith flexible confocal fluorescence lasermicroscopy (CFL) in a geneticallydefined mouse model of PDAC we were able to detect andgrade murine PanIN lesions in real time in <strong>vivo</strong>. Our diagnosticapproach is highly sensitive and specific and proved superior toclinically established fluorescein-enhanced imaging. Translation ofthis endoscopic technique into the clinic should tremendously improvedetection of pancreatic neoplasia, thus reforming managementof patients at risk for PDAC.molecularFluorescein:in <strong>vivo</strong> imaging | early detection | carcinoma in situ | geneticallyengineered mouse model | cathepsinMorphology and extent of fibrosisProSense 680:Pancreatic cancer (pancreatic ductal adenocarcinoma, PDAC)is one of the deadliest human malignancies, with an extremelypoor 5-y survival rate below 5% (1). Because patients generallypresent with symptoms relating to late stages of the disease, diagnosisof resectable PDAC is achieved in less than 15% of cases(1). However, investigators have reported that diagnosis and resectionof early-stage PDAC (

Imaging of other small animals...REPRODUCTIONRESEARCH<strong>In</strong> <strong>vivo</strong> imaging of in situ motility of fresh and liquidstored ram spermatozoa in the ewe genital tractXavier Druart, Juliette Cognié, Gérard Baril, Frédérique Clément 1 ,Jean-Louis Dacheux and Jean-Luc GattiUMR 6175 INRA, CNRS-Université de Tours-Haras Nationaux, Station de Physiologie de la Reproduction et desComportements, <strong>In</strong>stitut National de la Recherche Agronomique, 37380 Nouzilly, France and1 INRIA Paris-Rocquencourt, Domaine de Voluceau, Rocquencourt BP 105, 78153 Le Chesnay Cedex, FranceCorrespondence should be addressed to X Druart; Email: xavier.druart@tours.inra.frAbstractThe fertility of ram semen after cervical insemination is substantially reduced by 24 h of storage in liquid form. The effects of liquidstorage on the transit of ram spermatozoa in the ewe genital tract was investigated using a new procedure allowing direct observationof the spermatozoa in the genital tract. Ejaculated ram spermatozoa were double labeled with R18 and MitoTracker Green FM, and usedto inseminate ewes in estrus either cervically through the vagina or laparoscopically into the base of the uterine horns. Four hours afterinsemination, the spermatozoa were directly observed in situ using fibered confocal fluorescence microscopy in the base, middle and tipof the uterine horns, the utero-tubal junction (UTJ) and the oviduct. The high resolution video images obtained with this techniqueallowed determination of the distribution of spermatozoa and individual motility in the lumen of the ewe’s genital tract. The resultsshowed a gradient of increasing concentration of spermatozoa from the base of the uterus to the UTJ 4 h after intra-uterine inseminationinto the base of the horns. The UTJ was shown to be a storage region for spermatozoa before their transfer to the oviduct. The in vitrostorage of spermatozoa in liquid form decreased their migration through the cervix and reduced the proportion of motile spermatozoaand their straight line velocity at the UTJ and their transit into the oviduct.Reproduction (2009) 138 45–5345<strong>In</strong>troductionFertility in the ewe after cervical insemination has beenshown to be reduced when semen have been storedin liquid form for several hours, despite any majorreduction in semen quality as assessed by standardin vitro parameters such as motility (Salamon & Maxwell2000). A substantial decrease in fertility was alsoreported when frozen–thawed semen was used forcervical insemination, and this effect was partiallyovercome by intra-uterine insemination (Gillan &Maxwell 1999), which suggested that impairedmigration of spermatozoa through the cervix causedreduced fertility in ewes inseminated with preservedsemen. <strong>In</strong>deed, migration through the cervix appeared tobe the critical limiting factor for migration of ramspermatozoa from the vagina to the oviducts (Lightfoot& Restall 1971, Hawk & Conley 1975, Hawk 1983). Themigration of spermatozoa through the cervix mayinvolve increased contractility of the cervix at estrus(Wergin 1985) because cervical myoelectrical activitywas found to vary during the cycle and reach a peakaround ovulation (Cavaco-Gonçalves et al. 2006).The morphology of the cervix is very variable, andH Gharbi | Gen2Bio | 28 Mars 2013 | Nantesq 2009 Society for Reproduction and FertilityISSN 1470–1626 (paper) 1741–7899 (online)differences between animals, during the cycle (Kershawet al. 2005) and between breeds (Kaabi et al. 2006) havebeen reported. The differences in fertility reportedbetween breeds of sheep after insemination withfrozen–thawed semen might be related to differencesin sperm transit in the genital tract of the ewe (Fair et al.2005). The physiological study of sperm transit andquality in the female genital tract has to date beenlimited by the lack of techniques to observe the behaviorof spermatozoa in the genital tract of the living female ata cellular level. A new technique, fibered confocalfluorescence microscopy (FCM), provides direct observationof the microscopic structure of living tissue(Laemmel et al. 2004, Thiberville et al. 2007). Thetechnique is based on the principle of confocalmicroscopy, which provides an in-focus image of athin section within a biological sample, where themicroscope objective is replaced by a flexible fiber-opticminiprobe. With this technique it is possible to obtainimages with endogenous or exogenous tissue fluorophoresthrough a fiber-optic probe of 1 mm diameter orless. <strong>In</strong> this study, we developed a method based onFCM to observe the behavior of individual spermatozoaDOI: 10.1530/REP-09-0108Online version via www.reproduction-online.org
