Genetic effects of BIOPAD® on fibroblast primary culture.

The research article discusses the beneficial effects of a wound dressing material, BIOPAD®, on fibroblast behavior in terms of cell viability, survival and collagen production. Researchers also evaluated the impact of BIOPAD® on the expression of certain genes related to cell adhesion and traction resistance.

Background of the Study

• The study evaluated BIOPAD®, a soft sponge made exclusively of lyophilized type I native heterologous collagen derived from horse flexor tendon. BIOPAD® is gelatin-free and retains its native structure specific to skin tissue.
• BIOPAD® acts as an active wound dressing that plays a role in all stages of the wound healing process, stimulating the growth of granulation tissue and enhancing tissue regeneration. Its benefits also include balancing absorption and humidity at the wound surface, enabling gas exchange in soft tissues during wound healing, providing a barrier to prevent bacterial infections, and being completely non-adherent.
• According to this study, the use of BIOPAD® is painless for the patient and does not necessitate removal or dressing changes.

Evaluation of BIOPAD®’s Effects on Fibroblasts

• The researchers analyzed the impact of BIOPAD® on fibroblasts, a type of cells that produce collagen and play a critical role in wound healing, with respect to cell viability, survival, growth, and collagen production.
• The expression levels of certain genes involved in cell adhesion and traction resistance were studied using real-time Reverse Transcription-Polymerase Chain Reaction (real time RT-PCR) technology.
• These genes included elastin (ELN), desmoplakin (DSP), fibronectin 1 (FN1), fibrillin 1 (FBN1), integrin beta-1 (ITGB1), integrin alpha-1 (ITGA1), integrin alpha-5 (ITGA5), integrin alpha-2 (ITGA2), collagen type 1 alpha 1 (COL1A1), and collagen type 3 alpha 1 (COL3A1).

Findings of the Study

• After 48 hours of treatment, all genes, with the exception of ELN, DSP, ITGB1, and ITGA1, were up-regulated. Up-regulation refers to an increase in the rate of gene expression.
• The results of this research underscore the potential of BIOPAD® as a biocompatible and regenerative tool in medicine, indicating its positive effects on aspects of fibroblast behavior and gene expression that are key to the wound healing process.
