Résumé
L1CAM (L1 cell adhesion molecule) is a member of the L1 family of neural adhesion molecules, involved in the development of multiple organs and tissues, including kidneys, the enteric nervous system, and adrenal glands. The aim of this study was to analyze, at the immunohistochemical level, the expression of L1CAM in the human tongue, parotid glands, and the different segments of the gastrointestinal tract during human development. Immunohistochemical analysis for L1CAM was performed in the human tongue, parotid glands, and in the different segments of the gastrointestinal tract during development, starting from the 8th up to the 32nd week of gestation. Our results were given by the expression of the L1CAM protein in different segments of the gastrointestinal tract during development, starting from the 8th week up to the 32nd week of gestation. L1CAM-reactive cells appeared aggregated in small bodies, irregular in shape, showing L1CAM storage in the cytoplasm. L1CAM expressing bodies were frequently found to be connected one to the next by thin fibers, a finding suggestive of the existence of an L1CAM network inside the developing tissue. Our study confirms that L1CAM is involved in gut development, as well as in tongue and salivary gland development. These findings confirm that the role of L1CAM in fetal development is not restricted to the central nervous system and are necessary for further studies on the role of this molecule in human development.

Background
UNASSIGNED
L1CAM (L1 cell adhesion molecule) is a member of the L1 family of neural adhesion molecules, involved in the development of multiple organs and tissues, including kidneys, the enteric nervous system, and adrenal glands. The aim of this study was to analyze, at the immunohistochemical level, the expression of L1CAM in the human tongue, parotid glands, and the different segments of the gastrointestinal tract during human development.
Design and method
UNASSIGNED
Immunohistochemical analysis for L1CAM was performed in the human tongue, parotid glands, and in the different segments of the gastrointestinal tract during development, starting from the 8th up to the 32nd week of gestation.
Results
UNASSIGNED
Our results were given by the expression of the L1CAM protein in different segments of the gastrointestinal tract during development, starting from the 8th week up to the 32nd week of gestation. L1CAM-reactive cells appeared aggregated in small bodies, irregular in shape, showing L1CAM storage in the cytoplasm. L1CAM expressing bodies were frequently found to be connected one to the next by thin fibers, a finding suggestive of the existence of an L1CAM network inside the developing tissue.
Conclusion
UNASSIGNED
Our study confirms that L1CAM is involved in gut development, as well as in tongue and salivary gland development. These findings confirm that the role of L1CAM in fetal development is not restricted to the central nervous system and are necessary for further studies on the role of this molecule in human development.
