Summary
Human embryonic stem cells have defined existence periods and developmental pathways. Their genetic information is realized through the cambium, enabling tissue variability within embryonic origins and influencing adult mesenchymal development.
Area of Science:
- Developmental biology
- Human embryology
- Histogenesis
Background:
- Understanding human embryonic stem cells is crucial for developmental biology.
- Embryonic histogenesis involves complex cell differentiation processes.
- Published reports and original studies inform our knowledge of early human development.
Purpose of the Study:
- To determine the time limits for human embryonic stem cell existence.
- To classify the determination types of stem cells during divergent tissue development.
- To investigate the realization of genetic information from embryonic stem cells during embryogenesis.
Main Methods:
- Analysis of original studies on human embryonic histogenesis.
- Review of published reports on embryonic stem cell development.
- Observation of tissue development across different organs.
Main Results:
- Defined temporal boundaries for human embryonic stem cell viability.
- Identified specific determination pathways for stem cells in various organs.
- Demonstrated that cambium is the mechanism for realizing embryonic stem cell genetic information.
- Established that tissue process variability is confined to the embryonic primordium.
Conclusions:
- Human embryonic stem cells have a finite existence with specific developmental roles.
- The cambium plays a key role in translating embryonic stem cell potential into differentiated tissues.
- Mesenchymal development in adults is influenced by early embryonic programming.

00:58Embryonic 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.
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...
01:17Stem Cell Culture
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
00:57Embryonic 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...

01:14Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
