A Biologic and Physical Characterization of an Injectable Amniotic Membrane Designed for Treating Diabetic Foot...

Area of Science:

• Regenerative Medicine
• Biomaterials Science
• Wound Healing Research

Background:

• Diabetic foot ulcers (DFUs) significantly impact global health.
• Novel injectable therapies are needed for chronic wound repair.
• Micronized amniotic membrane offers a new approach to deliver therapeutic components.

Purpose of the Study:

• To characterize the components of a novel injectable drug for DFU treatment.
• To evaluate the in vitro performance and rheological properties of the injectable drug.

Main Methods:

• Liquid chromatography-tandem mass spectrometry and cytokine arrays for protein identification.
• ELISA for hyaluronic acid quantification.
• In vitro assays for cell viability, proliferation, and migration.
• Rheometry to assess viscosity and post-injection properties.

Main Results:

• Identified essential growth factors and proteins for wound healing.
• Injectable showed significantly higher protein and hyaluronic acid concentrations than amniotic fluid.
• Demonstrated increased cell viability, proliferation, and migration in vitro.
• Confirmed no alteration in drug properties after passing through a 22-gauge needle.

Conclusions:

• The novel injectable drug possesses components crucial for wound repair.
• In vitro results support its efficacy in promoting healing.
• The drug's stability and injectability are confirmed.
• These findings highlight its potential for DFU treatment.
