Detailed Insight on the Role of Mesenchymal Stem Cells Derived from Dental Pulp
Utilizing stem cells (SCs) and their derivatives could potentially resolve the obstacles faced by regenerative medicine therapies, such as a lack of donors and the development of strong immune responses, while allowing for the replacement of tissues and organs damaged by aging, disease or trauma.
Dental Pulp Stem Cells (DPSCs) are a variant of adult stem cells that represent an alternative source of stem cells for regenerative medicine, as they are relatively easy to obtain through safe and minimally invasive procedures. During development, dental pulp provides nutrition to the jaw, brain, and developing teeth due to the presence of mesenchymal stem cells. These cells are typically found in baby wisdom teeth, although they are discarded when the teeth are shed. Thus, DPSCs offer an exciting opportunity for the use of adult stem cells in regenerative medicine.
Adult human pulp tissue from impacted third molars, orthodontic teeth, and supernumerary teeth serve as a source for isolating DPSCs. These cells have shown intense clonogenicity, high proliferative capacity, and are even capable of forming mineralized nodules.
How Can Dental Pulp Cell Banking Safeguard Future Health?
Dental pulp cell banking, also known as dental stem cell banking, is an emerging field in regenerative medicine that aims to safeguard future health by preserving stem cells found in dental pulp, the soft tissue inside teeth. These stem cells have the potential to differentiate into various cell types, such as those found in teeth, bone, cartilage, and even neural tissue.
Here’s how dental pulp cell banking can contribute to safeguarding future health:
Regenerative Potential: Dental pulp stem cells (DPSCs) have the ability to differentiate into different types of cells, including odontoblasts (tooth-forming cells), osteoblasts (bone-forming cells), chondrocytes (cartilage-forming cells), and neural cells. This regenerative potential could be harnessed in the future for repairing damaged tissues and organs.
Personalized Medicine: Preserving your own dental pulp stem cells allows for potential use in personalized medicine. These cells would be genetically identical to you, reducing the risk of immune rejection if they are ever used for therapeutic purposes.
Diverse Applications: DPSCs have shown promise in treating various medical conditions, including dental and craniofacial defects, bone and cartilage injuries, nerve regeneration, and more. By banking these cells, you could have access to potential treatments for a wide range of health issues.
Emerging Therapies: As research in regenerative medicine progresses, new therapies and treatments using stem cells are being developed. By banking dental pulp stem cells now, you are positioning yourself to potentially benefit from these future advances.
Avoiding Ethical Concerns: Dental pulp stem cells can be collected without the ethical concerns associated with other types of stem cells, such as embryonic stem cells.
Non-Invasive Collection: Collecting dental pulp stem cells is a relatively non-invasive procedure that can be done during routine dental extractions or surgeries. This minimizes the discomfort and risks associated with the collection process.
Long-Term Preservation: Dental pulp stem cells can be cryopreserved and stored for many years without significant loss of viability or functionality. This means that even if you bank your cells at a young age, they could still be viable and effective later in life.
Clinical Applications of Mesenchymal Stem Cells Derived from Human Dental Pulp
Dental pulp stem cells (DPSCs) have shown significant potential for various applications in regenerative medicine and tissue engineering due to their ability to differentiate into different cell types. Here are some of the potential uses of DPSCs:
- Dental Tissue Regeneration: DPSCs can differentiate into odontoblasts, the cells responsible for forming dentin, the hard tissue in teeth. This makes them valuable for regenerating dentin and treating dental issues such as tooth decay or dental trauma.
- Bone Regeneration: DPSCs can differentiate into osteoblasts, which are responsible for bone formation. This property makes them useful for bone regeneration in cases of bone defects, fractures, or conditions like osteoporosis.
- Cartilage Regeneration: DPSCs can differentiate into chondrocytes, the cells that form cartilage tissue. This potential is being explored for treating conditions like osteoarthritis or cartilage injuries.
- Nerve Regeneration: DPSCs have demonstrated the ability to differentiate into neural-like cells. This property could be harnessed for nerve regeneration and repair after injuries or in conditions like spinal cord injuries.
- Corneal Regeneration: DPSCs have shown promise in corneal tissue engineering, offering potential treatments for corneal injuries or diseases.
- Cardiovascular Applications: While still in early stages of research, DPSCs are being investigated for their potential role in repairing damaged heart tissues after heart attacks or in cases of cardiovascular diseases.
- Diabetes Treatment: Some studies suggest that DPSCs might be used to generate insulin-producing cells, offering a potential treatment avenue for diabetes.
- Liver Regeneration: DPSCs are being explored for their ability to differentiate into hepatocyte-like cells, which could be used for liver tissue regeneration and addressing liver diseases.
- Neurological Disorders: DPSCs’ neural differentiation potential could be relevant in treating neurodegenerative disorders, although research in this area is still at an early stage.
- Cosmetic and Plastic Surgery: DPSCs could potentially be used in cosmetic procedures for tissue augmentation, scar reduction, and other aesthetic applications.
- Autoimmune and Inflammatory Disorders: The immunomodulatory properties of DPSCs are being investigated for their potential in treating autoimmune and inflammatory conditions.
- Wound Healing: DPSCs could be utilized to promote wound healing by assisting in tissue repair and regeneration.
Extraction and Preservation of Dental Pulp Mesenchymal Stem Cells
According to various studies, clinical labs have created a unique technology to preserve dental pulp stem cells from a child’s deciduous teeth, or wisdom teeth, for future use in treating health conditions. If the fallen teeth are 3 days old or younger, they can be temporarily placed in a sealed container of milk and shipped to our stem cell clinic in India. Upon arrival, these teeth undergo cleaning, processing, and cryogenic preservation, enabling their use for up to 20 years. We recommend that parents make use of this service from the ages of 6 to 12; however, each case is unique and will need to be assessed individually.
The use of dental pulp stem cells for regenerative therapies for neurodegenerative diseases and traumatic injuries, including those affecting the central nervous system and spinal cord, has been evidenced by a wealth of scientific research.
