Summary
Dental pulp cells (DPCs) are a promising source for induced pluripotent stem (iPS) cells, easily obtained and reprogrammed. DPC-derived iPS cells could form a bank matching 20% of the Japanese population for regenerative medicine.
Area of Science:
- Stem Cell Biology
- Regenerative Medicine
- Genetics
Background:
- Reprogramming somatic cells into induced pluripotent stem (iPS) cells requires specific transcriptional factors.
- Accessing suitable human cells for reprogramming can be challenging due to invasive procedures.
- Dental pulp cells (DPCs) offer an accessible source of somatic cells, easily obtained from extracted teeth.
Purpose of the Study:
- To evaluate dental pulp cells (DPCs) as an optimal source for generating induced pluripotent stem (iPS) cells.
- To assess the potential of DPC-derived iPS cells for establishing a histocompatible cell bank for regenerative medicine.
Main Methods:
- Testing 6 dental pulp cell (DPC) lines for reprogramming into iPS cells using 3 or 4 conventional reprogramming factors.
- Determining the Human Leukocyte Antigen (HLA) types of 107 DPC lines.
- Analyzing HLA data to predict the potential coverage of a hypothetical iPS cell bank.
Main Results:
- iPS cells were successfully established from 5 out of 6 tested DPC lines.
- Two DPC lines were identified as homozygous for all three major HLA loci.
- A potential iPS cell bank derived from these DPC pools could achieve perfect HLA matching for approximately 20% of the Japanese population.
Conclusions:
- Dental pulp cells (DPCs) are a viable and accessible source for generating induced pluripotent stem (iPS) cells.
- DPC collections hold significant promise for creating large-scale, histocompatible iPS cell banks.
- This approach could advance regenerative medicine by providing readily available, matched stem cells.

01:13Induced Pluripotent Stem Cells
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 called induced pluripotent stem...
01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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...
01:22iPS Cell Differentiation
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
01:21EPS and iPS Cells in Disease Research
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
