The effect of platelet-rich plasma on the neovascularization of surgically created equine superficial digital flexor tendon lesions.
- Journal Article
Summary
The research is about the effects of Platelet-Rich Plasma (PRP) on the healing process of tendon injuries in horses, with a particular focus on how PRP enhances neovascularization or blood vessel formation in the injured tendons.
Objective of the Research
The main aim of the study was to investigate the impact of platelet-rich plasma (PRP) on the blood vessel formation (neovascularization) in experimentally induced tendon injuries in horses.
- Tendons, in both human and equine athletes, have a slow and sub-optimal healing process due to their poor vascularization. This often leads to the recurrence of injuries.
- Platelet-rich plasma (PRP), a substance rich in growth factors, has been found to improve the tendon repair process. This is attributed to the high levels of growth factors in PRP, a number of which are involved in tendon healing.
- The study hypothesizes that one of the ways in which PRP optimizes tendon repair is through improvement of neovascularization, largely guided by its high content of vascular endothelial growth factor – a stimulator of blood vessel formation.
Methodology and Study Set Up
The researchers induced tendon injuries in horses and investigated the effects of PRP on neovascularization using color Doppler ultrasonography and immunological staining of Factor VIII.
- Color Doppler Ultrasonography is a medical imaging technique that visualizes the flow of blood through vessels, hence, effective in assessing neovascularization in injured tendons.
- Immunological staining of Factor VIII is used to identify endothelial cells, cells that make up blood vessels, hence, useful in detecting new blood vessel formation.
Findings of the Research
The findings showed that PRP resulted in significantly more neovascularization in the tendons than the placebo treatment up to 23 weeks post-treatment.
- This was demonstrated by both Doppler sonography and Factor VIII staining, therefore, the researchers concluded that neovascularization might be one of the explanations for the long-lasting effect of a single intratendinous treatment with PRP on tendon injuries.
