|August 30, 2023
Summary
Researchers developed a novel method to reverse the polarity of endometrial epithelial organoids (EEO), creating "apical-out" organoids. This breakthrough allows direct study of uterine epithelial interactions with embryos and pathogens in vitro.
Area of Science:
- Reproductive biology and stem cell research.
- Development of in vitro models for uterine epithelium.
Background:
- Uterine epithelium comprises hormone-responsive, polarized cells forming glands.
- Endometrial epithelial organoids (EEO) mimic in vivo properties but have limited apical access.
- Current EEO models hinder studies of apical surface interactions with embryos or pathogens.
Approach:
- Developed a straightforward strategy to reverse the polarity of endometrial epithelial organoids (EEO).
- Generated 'apical-out' organoids that maintain apical-basolateral orientation and hormone responsiveness.
- Validated the utility of polarity-reversed EEO for studying interactions with E. coli and blastocysts.
Key Points:
- Successfully created polarity-reversed endometrial epithelial organoids (apical-out).
- Apical-out EEO retain distinct apical-basolateral polarity and hormone responsiveness.
- Demonstrated feasibility of studying luminal interactions, including with blastocysts and E. coli.
Conclusions:
- Polarity-reversed EEO provide a valuable in vitro model for studying uterine epithelium.
- Enables direct investigation of apical surface interactions relevant to pregnancy and disease.
- Foundation for new functional assays assessing epithelial interactions with embryos and luminal factors.

01:56Gastrulation
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...
01:15Development 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...

01:33Cleavage and Blastulation
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.
01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:10Zygotic Development And Stem Cell Formation
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
01:20Embryonic Connective Tissues
During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development. Mesenchyme is...
