生理学
発達生物学
胃腸内科

背景:

生殖は女性の臓器の構造と機能を大きく変化させます
妊娠中の生理学的臓器の再構築のメカニズムを理解することは極めて重要です

研究の目的:

雌マウスの生殖過程における腸の再構築の特定のメカニズムを調査する.
生殖器官のサイズ変更に伴う分子ドライバーと細胞の変化を特定する.

主な方法:

生殖状態と非生殖状態における腸の改造の比較分析
SGLT3aトランスポーターを含む主要な分子マーカーの識別
伝送器の機能と信号伝達経路の解明のための電気生理学的および遺伝学的研究.

主要な成果:

生殖の再編成は予期的なもので,食事や微生物群によって引き起こされる変化とは異なります.
細腸は不可逆的な伸縮と可逆的な毛の成長を示し, 拡張した静脈の祖先を示しています.
SGLT3aトランスポーターは陽子とナトリウムを検出し,隣接する原始細胞の膨張との成長をサポートします.

結論:

生殖性腸改造は,親細胞の膨張と臓器の成長を調節する特定の分子信号 (SGLT3a) を含む.
この研究は生理学的臓器の再構築における予期せぬ特異性を明らかにした.

Anatomy of the Intestines

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...

Renewal of Intestinal Stem Cells

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Proliferative Phase

Proliferative Phase

The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...

Development of the Sexual Organs in the Embryo and Fetus

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...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Histology of the Small Intestine

Histology of the Small Intestine

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
