Determination

Determination

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In contrast, determination...

Gastrulation

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...

Cleavage and Blastulation

Cleavage 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.

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 male...

Zygotic Development And Stem Cell Formation

Zygotic 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...

Embryonic Connective Tissues

Embryonic 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...

Background:

Protein shedding, or cleavage of plasma membrane proteins, is crucial for cell signaling, adhesion, migration, proliferation, and differentiation.
ADAM (a disintegrin and metalloproteinase) surface metalloproteases are key enzymes mediating this shedding process.
Previous studies using gene inactivation in model organisms highlight the essential roles of ADAM proteins in embryonic development.

Purpose of the Study:

To review the specific contributions of four distinct ADAM protein subfamilies to developmental processes.
To synthesize current knowledge on the functional significance of ADAM proteins in embryogenesis across diverse taxa.

Main Methods:

Literature review of studies involving gene inactivation and functional analysis of ADAM proteins.
Comparative analysis of ADAM subfamily roles in embryonic development in nematodes, flies, frogs, birds, and mammals.

Main Results:

ADAM proteins play indispensable roles in embryonic development, with specific subfamilies exhibiting distinct or overlapping functions.
Evidence from various model organisms consistently demonstrates the necessity of ADAM-mediated protein shedding for normal development.

Conclusions:

ADAM metalloproteases are critical regulators of embryonic development through their control of protein shedding.
Understanding the differential roles of ADAM subfamilies provides insights into conserved and divergent mechanisms of developmental regulation.
