Polynucleotides Derived from Trout Sperm DNA: An Innovative Approach to Tendinopathy, Osteoarthritis, and Ligamentous Injuries

Table of Contents


Tendinopathy, osteoarthritis, and ligamentous injuries are common musculoskeletal conditions that can be painful and challenging to treat. Conventional approaches often provide limited relief, driving the search for novel solutions. One such breakthrough involves the use of polynucleotides derived from trout sperm DNA, offering new hope for individuals suffering from these conditions. In this article, we will explore the science behind this innovative treatment and its unique relationship to human DNA while shedding light on the process of harvesting polynucleotides from trout sperm.

Understanding Tendinopathy, Osteoarthritis, and Ligamentous Injuries

  1. Tendinopathy: Tendinopathy encompasses a spectrum of conditions affecting tendons, leading to pain, swelling, and reduced mobility. It can result from overuse, aging, or other factors and frequently affects tendons like the Achilles, rotator cuff, and patellar tendons.
  2. Osteoarthritis: Osteoarthritis is a degenerative joint disease characterized by the gradual breakdown of joint cartilage and underlying bone. It results in pain, stiffness, and reduced joint mobility, most commonly affecting weight-bearing joints like the knees, hips, and spine.
  3. Ligamentous Injuries: Ligamentous injuries involve damage to the strong connective tissue bands (ligaments) that stabilize joints, leading to pain, instability, and limited joint mobility. These injuries can occur due to sudden trauma or chronic stress.

Polynucleotides and Their Unique Source

Polynucleotides, often referred to as polynucleotide complexes (PNCs), are biological substances derived from DNA and RNA fragments. An intriguing aspect of this innovation is the utilization of polynucleotides derived from trout sperm DNA:

Polynucleotides Derived from Trout Sperm DNA:

  • Trout sperm DNA is inherently rich in polynucleotides, making it a valuable source for these molecules.
  • The polynucleotides obtained from trout sperm DNA contain essential genetic information for cellular growth, repair, and maintenance.
  • They exhibit anti-inflammatory properties and have the capacity to stimulate tissue regeneration, rendering them a promising option for treating musculoskeletal conditions.

The Process of Harvesting Polynucleotides from Trout Sperm

Polynucleotides harvested from trout sperm DNA involve a meticulous process to extract and purify these valuable molecules. While the exact techniques may vary, here’s an overview of the general steps involved:

  1. Collection: Trout sperm is collected through non-harmful means, ensuring the fish’s well-being.
  2. Extraction: The DNA is carefully extracted from the collected sperm.
  3. Purification: The DNA is then purified to obtain high-quality polynucleotides.
  4. Formulation: The purified polynucleotides are formulated for use in medical treatments.

The Relationship to Human DNA

The relationship between polynucleotides derived from trout sperm DNA and human DNA lies in the fundamental genetic structure they share. The basic building blocks of DNA and RNA are consistent across species, including humans and trout. Therefore, the genetic information contained in these polynucleotides can interact with and influence human cellular processes.

How PDRNs Really work?

Polydeoxyribonucleotides (PDRNs) are a family of DNA-derived drugs, characterized by a molecular weight of 50–1500 kDa, that derive from a standardized process of purification and sterilization of sperm DNA from Oncorhynchus mykiss (Salmon Trout) or Oncorhynchus keta (Chum Salmon).

They have been shown to have a crucial role in suppressing the release of pro-inflammatory cytokines and activating anti-inflammatory effects. Moreover, they have been proven to have various other beneficial effects, such as stimulating wound healing, tissue repair, and anti-ischemic action.

PDRN is an agonist of one of the adenosine-activated receptors, the A2A receptor. Adenosine binds and activates four specific adenosine receptors referred to as A1, A2A, A2B, and A3.

The A2A receptor plays a crucial role in the regulation of inflammation, cell growth, angiogenesis, oxygen consumption, and cellular ischemia.

Applications in Musculoskeletal Health

The remarkable properties of polynucleotides offer numerous applications in the treatment of musculoskeletal conditions:

  1. Anti-Inflammatory Effects:
    • These polynucleotides are known for their ability to reduce inflammation, a common feature in tendinopathy, osteoarthritis, and ligamentous injuries.
    • By mitigating inflammation in affected tissues, they can alleviate pain and improve overall function.
  2. Tissue Regeneration:
    • Polynucleotides can stimulate cellular repair and regeneration, a crucial element in healing damaged tendons, promoting the growth of new cartilage in osteoarthritic joints, and repairing injured ligaments.
  3. Pain Management:
    • Pain is a common and debilitating symptom in these conditions. Polynucleotides play a pivotal role in reducing inflammation and enhancing tissue repair, ultimately improving patients’ quality of life.
  4. Minimally Invasive Treatment:
    • The administration of polynucleotide-based therapies typically involves minimally invasive injections, reducing the need for extensive surgical procedures.


Polynucleotides derived from trout sperm DNA offer a novel and promising approach to treating tendinopathy, osteoarthritis, and ligamentous injuries. While this field is still emerging, early results and patient testimonials are encouraging. Further research and clinical trials are essential to determine their safety and long-term effectiveness fully.

The exciting relationship between these polynucleotides and human DNA underscores their potential to revolutionize musculoskeletal healthcare. As research advances, this innovative approach may provide relief, improved function, and an enhanced quality of life for individuals seeking more effective solutions for their musculoskeletal health. It is an exciting time in the realm of medical innovation as these pioneering treatments open new doors for those dealing with these common and often debilitating conditions.
