Review of various preparation techniques using natural/synthetic polymers and inorganic compounds.

Analysis of refinements in material characterization, microbead generation, and coating techniques.

Main Results:

Matrix-core/shell (e.g., alginate) microcapsules are the most studied approach.
Liquid-core capsules demonstrate improved protein production and cell survival.
Emerging techniques like direct cell aggregate coating aim to reduce implant size.

Conclusions:

Microcapsule performance depends heavily on material properties and preparation methods.
While pre-clinical results are promising, existing methods need further refinement for clinical translation.
Advancements in microencapsulation are crucial for effective cell-based therapies.
