    Insights

    This study maps human islet development from birth to age ten, revealing distinct maturation timelines for insulin and glucagon secretion. Understanding this process is key for diabetes research.

    Area of Science:

    • Developmental Biology
    • Endocrinology
    • Human Pancreatic Physiology

    Background:

    • Human endocrine cell differentiation and islet morphogenesis are crucial for islet function but poorly understood.
    • The precise timeline of early human islet development remains undefined.

    Purpose of the Study:

    • To elucidate the morphological and spatiotemporal changes during early human islet cell development and maturation.
    • To create an integrated model of endocrine cell formation and islet architecture.

    Main Methods:

    • Analysis of 115 pediatric pancreata from birth to 10 years.
    • Quantitative analysis using confocal microscopy and whole-slide imaging.
    • Assessment of insulin and glucagon secretion in isolated pediatric islets.

    Main Results:

    • Developed an integrated model of endocrine cell formation, islet architecture, and vascularization.
    • Identified heterogeneity and abundance of endocrine cell types.
    • Observed a temporal difference in insulin secretion maturation compared to glucagon secretion.

    Conclusions:

    • Provides a comprehensive framework for postnatal and pediatric pancreatic islet development.
    • Offers insights into islet biology and potential links to diabetes risk.
    • Facilitates integration of future genetic and genomic data in islet research.

    Anatomy of the Intestines01:23

    Anatomy of the Intestines

    Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
    Small Intestines
    The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
    Gastrulation01:56

    Gastrulation

    Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...

    Gross Anatomy of the Stomach

    The human stomach is a vital part of the digestive system, performing multiple functions. It is located within the peritoneum, a serous membrane that lines the abdominal cavity. The stomach plays a central role in processing food substances and interacts with other digestive organs through coordinated digestive processes. The stomach has a characteristic J-shape and is divided into four main regions. The cardia is the first section where the esophagus connects to the stomach and is the entry...

    Development of the Sexual Organs in the Embryo and Fetus

    Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
    Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...

    Anatomy of the Gastrointestinal System

    The human digestive system is an intricate and essential network for nutrient absorption and waste elimination. It encompasses the gastrointestinal (GI) tract and several accessory organs.

    Development of Human Microbiota01:30

    Development of Human Microbiota

    The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
