A Simplified 3D-Plasma Culture Method for Generating Minimally Manipulated Autologous Equine Muscle-Derived...

Area of Science:

• Veterinary Medicine
• Regenerative Medicine
• Cell Biology

Background:

• Musculoskeletal injuries pose significant challenges in athletic horses, with limited regenerative capacity and conventional treatments often proving insufficient.
• Current cell culture methods, particularly 2D systems using fetal bovine serum (FBS), do not fully replicate the in vivo environment, hindering the development of effective regenerative therapies.
• There is a critical need for advanced therapeutic strategies, including ortho-biologics and mesenchymal stem/stromal cells, to address these limitations.

Purpose of the Study:

• To develop and characterize a novel, simplified 3D cell culture method for isolating muscle-derived progenitor cells in horses.
• To evaluate the potential of this autologous 3D culture system for equine regenerative medicine applications.
• To establish a more physiologically relevant and clinically applicable platform for generating equine cell-based therapies.

Main Methods:

• Isolation of muscle-derived progenitor cells using a novel autologous plasma-based gel and a specialized cell retrieval solution.
• Culture of cells in a 3D environment to better mimic native tissue architecture and cell-cell interactions.
• Assessment of cell characteristics, including immunomodulatory effects on T lymphocytes, trilineage differentiation potential, and immunophenotype.

Main Results:

• The developed 3D culture method successfully isolated and expanded muscle-derived progenitor cells.
• Cultured cells demonstrated significant immunomodulatory effects on T lymphocytes.
• Cells exhibited trilineage differentiation potential and possessed immunophenotypic characteristics consistent with mesenchymal stem/stromal cells.

Conclusions:

• The novel 3D autologous plasma-based culture technique provides a simplified, serum-free, and time-efficient method for equine regenerative medicine.
• This approach offers a promising platform for generating minimally manipulated, autologous cell products with enhanced clinical safety and potential.
• The streamlined technique is suitable for researchers and clinicians seeking advanced cell-based therapies for equine musculoskeletal pathologies.
