Early-life programming of adipose tissue

Area of Science:

• Metabolic health
• Developmental biology
• Endocrinology

Background:

• Childhood obesity is a growing global health crisis with serious co-morbidities.
• The maternal environment during pregnancy is critical for metabolic programming and can influence obesity transmission across generations.
• White adipose tissue is a key target for metabolic programming influenced by the maternal environment.

Purpose of the Study:

• To review adipose tissue physiology and development.
• To examine maternal influences during the perinatal period on obesity development.
• To discuss how maternal factors impact fetal growth and adiposity.

Main Methods:

• Review of current literature on adipose tissue physiology and development.
• Analysis of hormonal factors in fetal/postnatal programming.
• Examination of maternal nutritional, hormonal, epigenetic, and microbiome changes in obesity.

Main Results:

• Adipose tissue development is sensitive to nutritional, hormonal, and epigenetic signals during critical gestational and early postnatal periods.
• Maternal obesity and associated changes can disrupt fetal growth and adiposity.
• Evidence supports the developmental origins of health and disease concept linking early-life programming to adult obesity.

Conclusions:

• Early-life adipose tissue programming by maternal factors is crucial for long-term metabolic health.
• Understanding these mechanisms offers potential strategies for combating the global obesity epidemic.
• Interventions promoting healthy early-life programming may prevent obesity in future generations.
