Investigation for the pro-angiogenic properties of eggshell-derived nanoparticles

Area of Science:

• Biomaterials Science
• Nanotechnology
• Regenerative Medicine

Background:

• Eggshells are abundant agricultural waste, primarily composed of calcium carbonate.
• Calcium and magnesium from eggshells play crucial roles in biological processes, including angiogenesis.
• The potential of eggshell-derived nanomaterials for therapeutic applications remains largely unexplored.

Purpose of the Study:

• To design and characterize calcium-rich nanoparticles from unfertilized (U-ES) and fertilized (F-ES) eggshells.
• To investigate the pro-angiogenic potential of these eggshell-derived nanoparticles (ES-NP).
• To evaluate the biocompatibility of ES-NP for potential biomedical uses.

Main Methods:

• Calcination of raw eggshells to produce U-ES-NP and F-ES-NP.
• Characterization of nanoparticles using various analytical techniques.
• In vitro (cell proliferation, tube formation), ex vivo (chick aorta assay), and in vivo (chick chorioallantoic membrane assay) validation of pro-angiogenic properties.
• Ex vivo hemolysis assay to assess biocompatibility.

Main Results:

• Successfully synthesized and characterized U-ES-NP and F-ES-NP.
• Demonstrated significant pro-angiogenic activity of both U-ES-NP and F-ES-NP across in vitro, ex vivo, and in vivo models.
• Confirmed the biocompatibility of ES-NP through hemolysis assays, showing minimal red blood cell lysis.

Conclusions:

• Biocompatible eggshell-derived nanoparticles (ES-NP) possess notable pro-angiogenic properties.
• These findings highlight the therapeutic potential of ES-NP for diseases requiring blood vessel formation.
• Further biosafety evaluations are warranted for advanced biomedical applications.
