Summary
Glioma-associated oncogene 1 (Gli1+) cells are identified as mesenchymal stem cells crucial for tissue repair in bones and teeth. These Gli1+ cells show promise for future stem cell-based tissue engineering applications.
Area of Science:
- Stem Cell Biology
- Regenerative Medicine
- Tissue Engineering
Background:
- Mesenchymal stem cells (MSCs) are vital for tissue homeostasis and repair.
- Identifying specific MSC markers is key to understanding their in vivo niche.
- Glioma-associated oncogene 1 (Gli1) is a newly recognized marker for a subset of MSCs.
Purpose of the Study:
- To review the role of Gli1-positive (Gli1+) cells as a mesenchymal stem cell subpopulation.
- To explore the function of Gli1+ cells in bone and teeth.
- To discuss the potential of Gli1+ cells in stem cell-based tissue engineering.
Main Methods:
- Literature review of studies investigating Gli1+ cells.
- Analysis of the role of Gli1+ cells in skeletal and dental tissues.
- Synthesis of findings regarding MSC identification and function.
Main Results:
- Gli1+ cells are identified as a distinct subpopulation of MSCs.
- These cells actively support homeostasis and injury repair in bones and teeth.
- Evidence suggests Gli1+ cells possess regenerative capabilities.
Conclusions:
- Gli1+ cells represent a significant MSC subpopulation with critical roles in skeletal and dental regeneration.
- The unique properties of Gli1+ cells offer exciting prospects for stem cell-based tissue engineering strategies.

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...

Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...
