The pancreas is an organ of endodermal origin. It is composed of two different tissues; exocrine (acini and ducts) and endocrine (islet of Langerhans). The Bone Morphogenetic Proteins (BMP) are secreted growth factors from the TGFβ superfamily. These prote ...
CONTEXT: Leptin was initially proposed to be the antiobesity hormone. Now it is realised that leptin is more a signal molecule that communicates nutritional status to the brain, and that it is involved in bone formation by having an antiosteogenic action. ...
Both beta-catenin and plakoglobin can stimulate the expression of Lef/Tcf target genes in vitro. beta-Catenin is known to associate with Lef/Tcf factors and to participate directly in transactivation in vivo, whereas the role of plakoglobin in transcriptio ...
The self-renewing epithelium of the small intestine is ordered into stem/progenitor crypt compartments and differentiated villus compartments. Recent evidence indicates that the Wnt cascade is the dominant force in controlling cell fate along the crypt-vil ...
The influence of a chronic social stress upon immunity was investigated in Wistar rats, submitted for four weeks to two different behavioral situations, balanced in a factorial design: housing with three females and membership rotation. The combination of ...
An increasing number of patients are being treated with growth hormone (GH) for the enhancement of body growth but also as an anti-aging strategy. However, the side effects of GH have been poorly defined. In this study we determined the effect of GH on wou ...

During embryonic development, organs arise along the gut tube as a series of buds in a stereotyped anterior-posterior (A-P) pattern. Using chick-quail chimeras and in vitro tissue recombination, we studied the interactions governing the. induction and main ...
We present a single-photon camera for fluorescence imaging, with a time resolution better than 100ps, capable of providing both intensity and lifetime images. the camera was fabricated in standard CMOS technology. With this FluoCam we show the possibility ...
The small heterodimer partner (SHP) is an atypical nuclear receptor known mainly for its role in bile acid homeostasis in the enterohepatic tract. We explore here the role of SHP in the testis. SHP is expressed in the interstitial compartment of the adult ...
Culturing and comparing the discrete stages of tumorigenesis provide a route to defining important components of the cancer phenotype and, in addition, present the opportunity to establish cell cultures more representative of normal cells than the ultimate ...
