Abstract
Pancreatic organogenesis is a multistep process that requires the cooperation of several signaling pathways. In this context, the role of pancreatic mesenchyme is important to define the epithelium development; nevertheless, the precise space–temporal signaling activation still needs to be clarified. This study reports a dissection of the pancreatic embryogenesis, highlighting the molecular network surrounding the epithelium–mesenchyme interaction. To investigate this crosstalk, pancreatic epithelium and surrounding mesenchyme, at embryonic day 10.5, were collected through laser capture microdissection (LCM) and characterized based on their global gene expression. We performed a bioinformatic analysis to hypothesize crosstalk interactions, validating the most promising genes and verifying the precise localization of their expression in the compartments, by RNA in situ hybridization (ISH). Our analyses pointed out also the c-Met gene, a very well-known factor involved in stimulating motility, morphogenesis, and organ regeneration. We also highlighted the potential crosstalk between Versican (Vcan) and Syndecan4 (Sdc4) since these genes are involved in pancreatic tissue repair, strengthening the concept that the same signaling pathways required during pancreatic embryogenesis are also involved in tissue repair. This finding leads to novel strategies for obtaining functional pancreatic stem cells for cell replacement therapies.

Abstract
In the group of 35 patients with cerclage, intermediate fetal mortality was reduced from 37.1% to 0 (p < 0.001); late fetal mortality rate from 8.5% to 2.8% (p = 0.606); prematurity from 65.7% to 5.7% (p < 0.001); newborn underweight from 11.4% to 5.7% (p = 0.671); newborns with very low weight from 34.2% to 0 (p < 0.001) and the abortion rate from 8.5% to 0 ( p < 0.001). In the group of 19 patients without buckling, intermediate fetal mortality was reduced from 26.3% to 10.5% (p = 402); late fetal mortality from 63.1% to 0 (p < 0.001); prematurity 78.9% to 31.5% (p < 0.009); the newborn of low weight from 31.5% to 10.5% (p = 0.234); newborns with very low weight from 68.4% to 15.7% (p < 0.003) and the abortion rate from 36.8 to 0 (p < 0.001). In conclusion, we believe the results of this study demonstrate the effectiveness of therapeutic and prophylactic cervical cerclage associated with prolonged antibiotic therapy.
