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...

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 Stem Cells

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Area of Science:

Developmental Biology
Stem Cell Biology
Regenerative Medicine

Background:

Embryonic development involves complex self-organization.
Human embryonic stem cells (ESCs) offer a model for studying these processes in vitro.
Studying ESC self-organization provides insights into human development otherwise inaccessible.

Purpose of the Study:

To review recent literature on human ESC self-organization.
To focus on the formation of embryonic germ layers and neural rosettes.
To discuss the mechanisms and challenges in this field.

Main Methods:

Review of existing scientific literature on human ESC self-organization.
Analysis of studies focusing on germ layer and neural rosette formation.
Examination of the role of TGFβ signaling in initiating self-organization.

Main Results:

Human ESCs can recapitulate in vitro the self-organization observed in vivo.
Both activation and inhibition of TGFβ signaling can trigger self-organization.
Distinct molecular mechanisms underlie self-organization initiated by TGFβ signaling modulation.

Conclusions:

Human ESCs are a powerful model for studying self-organization.
TGFβ signaling plays a critical role in initiating ESC self-organization.
Further research is needed to fully understand the mechanisms and challenges in the field.
