Summary
Embryonic stem cells can form complex, three-dimensional gut-like structures in vitro. These structures mimic embryonic development, offering insights into gastrointestinal development and cell differentiation.
Area of Science:
- Developmental Biology
- Stem Cell Biology
- Gastroenterology
Background:
- Embryonic stem (ES) cells possess pluripotency, differentiating into diverse cell lineages.
- In vitro models are crucial for studying complex developmental processes like organogenesis.
Purpose of the Study:
- To investigate the potential of ES cells to form organized gut-like structures in vitro.
- To analyze the developmental process and cellular composition of these in vitro-derived gut structures.
Main Methods:
- ES cell suspension cultured in hanging drops without leukemia inhibitory factor to form embryoid bodies (EBs).
- EB outgrowth culture on plastic dishes for 21 days.
- Histological and functional analysis of the resulting three-dimensional gut-like structures.
Main Results:
- Six-day-old EBs, after 21 days of outgrowth culture, developed into organized gut-like structures.
- These structures exhibited spontaneous contractions and coordinated peristalsis, resembling in vivo embryonic gut development.
- The structures comprised an epithelium, lamina propria, muscularis, scattered ganglia, and interstitial cells of Cajal.
Conclusions:
- ES cell-derived embryoid bodies can recapitulate key aspects of embryonic gastrointestinal development in vitro.
- This model provides a platform for studying cell lineage commitment and gut organization.
- The 6-day egg-cylinder stage EBs are suitable for generating enteric derivatives and mimicking gut formation.

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...
01:10Zygotic 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...
01:23Renewal 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 goblet,...
01:51Determination
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...
