Mesenchymal Stem/Stromal Cells Microencapsulation for Cell Therapy

Area of Science:

• Biotechnology and Regenerative Medicine
• Cell Therapy and Tissue Engineering

Background:

• Mesenchymal stem/stromal cells (MSCs) face challenges for in vivo therapeutic use due to immune rejection.
• Cell microencapsulation offers a solution by shielding MSCs within a semipermeable membrane.

Purpose of the Study:

• To review materials and techniques for microencapsulating MSCs.
• To discuss recent advancements, benefits, drawbacks, and in vivo translation of encapsulated MSCs in cell therapy.

Main Methods:

• Discusses popular microencapsulation materials: alginate, collagen, and cellulose.
• Highlights common techniques: air jet extrusion, microfluidics, and emulsion.
• Compares methods based on microcapsule size and material compatibility.

Main Results:

• Microencapsulation enhances MSC survival and engraftment post-infusion.
• Enables targeted delivery and improved cellular interactions in a 3D environment.
• Different materials and techniques yield varying microcapsule characteristics.

Conclusions:

• Microencapsulation is a key strategy for overcoming in vivo MSC implementation barriers.
• Encapsulated MSCs demonstrate improved therapeutic potential and in vivo translation capabilities.
• Further research into materials and techniques can optimize cell therapy outcomes.
