Polydeoxyribonucleotide
Polydeoxyribonucleotide (PDRN), is a mixture of single-stranded oligonucleotides with weight ranging from approximately 50 kDa to 1500 kDa, peaking around 350kDa in some commercial forms. PDRN was originally isolated from human placenta for potential pharmaceutical applications in Italy, but it is now obtained by fractionating and purifying DNA extracted from salmon or trout sperm. Novel sources of PDRN are being further studied but salmon or trout sperm cells are more commonly used as they are easily processed and readily available DNA source. PDRN has anti-inflammatory effects, stimulates collagen production and promotes angiogenesis, and is mainly used in pharmaceutical applications with purported anti-wrinkle and anti-aging effects. Additionally, it has shown improvement and acceleration of wound healing and tissue repair, demonstrated in treatment of tendinopathy and diabetic foot ulcers. The mechanism involves activation of adenosine A2A receptors, upregulating expression of vascular...
