Galectin-10 Characterization in Cleft Lip Palate - Affected Palatal Tissue.

Area of Science:

• Craniofacial development and birth defects
• Immunology and inflammation
• Tissue regeneration and repair

Background:

• Cleft lip and palate (CLP) is a common craniofacial birth defect.
• Chronic inflammation is implicated in failed palatal development.
• The role of Galectin-10 (Gal-10) in CLP tissue inflammation and regeneration is largely unknown.

Purpose of the Study:

• To detect the presence and investigate the potential role of Gal-10 in cleft-affected facial tissues.
• To examine the ontogenetical aspect of Gal-10 expression in relation to cleft palate development.

Main Methods:

• Craniofacial cleft tissue samples were collected from 21 children (8 months–12.7 years) undergoing surgery.
• Control groups included healthy subjects and those with lip frenulum plastic surgery.
• Gal-10 positive cells were quantified using semiquantitative counting and nonparametric statistical analysis.

Main Results:

• Elevated Gal-10 levels were observed in the palatal epithelium, increasing with age in both control and patient groups.
• A notable difference in Gal-10 expression was found in muscle tissue between milk and mixed dentition cleft palates.
• Milk dentition cleft palates showed higher Gal-10 expression in muscle tissue compared to mixed dentition.

Conclusions:

• Increased Gal-10 expression in the palatal epithelium of cleft-affected children suggests a role in local defense and barrier function.
• Palatal muscles are not a primary site for Gal-10 expression in healthy or cleft conditions.
• Sporadic Gal-10 in connective tissue indicates individual tissue changes unrelated to the specific disease.
