Summary
Evidence suggests axial stem cells exist and contribute to spinal cord, skeleton, and muscle development. However, their multipotency and exact contribution require further investigation for a complete understanding of axial body formation.
Area of Science:
- Developmental biology
- Stem cell research
- Comparative embryology
Background:
- The development of axial tissues (spinal cord, skeleton, musculature) in chick and mouse embryos is thought to involve multipotent stem cells.
- Understanding these axial stem cells is crucial for comprehending embryonic development and tissue regeneration.
Purpose of the Study:
- To evaluate the evidence for the existence and multipotency of axial stem cells.
- To review the characteristics, location, evolutionary conservation, and regulatory mechanisms of these putative stem cells.
Main Methods:
- Literature review and synthesis of existing experimental data.
- Analysis of studies on chick and mouse embryonic development.
- Comparative analysis across vertebrate species.
Main Results:
- Strong evidence supports the existence of axial stem cells.
- Definitive information regarding the multipotency and extent of contribution of these cells to the axial body plan is limited.
- Key molecular characteristics, locations, evolutionary conservation, and regulatory signaling pathways are discussed.
Conclusions:
- Axial stem cells are likely integral to the progressive generation of axial tissues.
- Further research is needed to precisely define the multipotency and functional contribution of these cells.
- Understanding these stem cells and their regulation offers insights into vertebrate axial development.

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

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...
01:33Whole Body Regeneration
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential; even...
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...
01:56Gastrulation
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...
01:19Mesenchymal 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...
