Summary
Supernumerary teeth derived stem cells (SNTSCs) share properties with dental pulp stem cells (DPSCs) but exhibit higher proliferation and altered migration. Gene expression analysis revealed significant differences, suggesting unique potential for SNTSCs.
Area of Science:
- Stem cell biology
- Regenerative medicine
- Oral biology
Background:
- Supernumerary teeth are a common dental anomaly.
- Stem cells from these teeth (SNTSCs) have potential applications in regenerative dentistry.
- Understanding SNTSCs characteristics is crucial for their therapeutic use.
Purpose of the Study:
- To characterize supernumerary teeth derived stem cells (SNTSCs).
- To compare SNTSCs with normal dental pulp stem cells (DPSCs).
- To investigate gene expression profiles and functional differences.
Main Methods:
- Flow cytometry for stem cell marker analysis.
- In vitro assays for proliferation, migration, and differentiation.
- RNA sequencing for global gene expression profiling.
- Gene knockdown experiments to assess functional impact of differential expression.
Main Results:
- SNTSCs exhibit multipotent differentiation capacity (adipocytes, chondrocytes, osteoblasts).
- SNTSCs show significantly higher proliferation and lower migration rates compared to DPSCs.
- RNA sequencing identified 12,861 differentially expressed genes between SNTSCs and DPSCs.
- Specific genes (FUT11, FAM155A, BRD2, GLUD1) were found to influence SNTSC proliferation and migration.
Conclusions:
- SNTSCs possess stem cell properties comparable to DPSCs.
- SNTSCs demonstrate distinct biological characteristics, including enhanced proliferation.
- These findings highlight the unique potential of SNTSCs for regenerative applications.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.

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.

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...
