Summary
This review characterizes stem cells in early mammalian embryo development, focusing on vole trophoblast and extraembryonic endoderm stem cells. We compare these to mouse cells and explore signaling pathways maintaining their undifferentiated state.
Area of Science:
- Developmental biology
- Stem cell research
- Mammalian embryogenesis
Background:
- Extraembryonic tissues are crucial for embryonic development.
- Stem cells within these tissues maintain pluripotency and differentiation potential.
- Understanding these stem cells informs developmental processes and regenerative medicine.
Purpose of the Study:
- To characterize stem cells from vole trophoblast and extraembryonic endoderm.
- To perform a comparative analysis with corresponding mouse stem cells.
- To investigate signaling pathways maintaining stem cell pluripotency.
Main Methods:
- Isolation and characterization of stem cells from vole embryos.
- Comparative analysis of vole and mouse extraembryonic stem cells.
- Bioinformatic analysis of potential signaling pathways.
Main Results:
- Vole trophoblast and extraembryonic endoderm stem cells exhibit distinct characteristics.
- Comparative analysis reveals conserved and divergent features with mouse stem cells.
- Key signaling pathways potentially maintaining stem cell identity were identified.
Conclusions:
- Stem cells in vole extraembryonic tissues share similarities with mouse counterparts.
- Specific signaling pathways are implicated in maintaining their undifferentiated state.
- This research provides insights into conserved mechanisms of early mammalian development.

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...
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.
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...

01:27Source And Potency Of Stem Cells
Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...
01:19Mesenchymal Stem Cells
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
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...
