Fate Mapping of Human Embryonic Stem Cells by Teratoma Formation
Published on: August 2, 2010
Summary
Remarkable similarities between mouse teratoma stem cells and embryonic cells allow tumor cells to contribute to normal development. This finding opens new avenues for studying early mammalian development using isolated stem cell lines.
Area of Science:
- Developmental biology
- Cancer research
- Stem cell biology
Background:
- Recent research highlights striking similarities between teratocarcinoma stem cells and early embryonic cells in mice.
- Teratocarcinoma stem cells can integrate with embryonic cells and contribute to the development of a fully normal mouse.
- This resemblance provides a unique model for investigating early mammalian development.
Purpose of the Study:
- To explore the functional similarities between teratocarcinoma stem cells and embryonic stem cells.
- To investigate the potential of teratocarcinoma stem cells to participate in normal embryonic development.
- To leverage teratocarcinoma-derived stem cell lines for advanced research into early mammalian development.
Main Methods:
- Isolation and characterization of stem cell lines from mouse teratocarcinomas.
- Biochemical analyses of teratocarcinoma and embryonic stem cells.
- Immunological comparisons between cell types.
- Genetic studies utilizing teratocarcinoma-derived stem cell lines.
Main Results:

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.
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...
Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

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...
Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Mutagenicity and Carcinogenicity
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
