Background:

  • Decellularized tissues and organs are vital for tissue engineering and regenerative medicine.
  • Various decellularization methods exist, tailored to specific tissues and organs.

Purpose of the Study:

  • To describe common decellularization techniques.
  • To analyze the impact of these methods on the extracellular matrix (ECM) scaffold.

Main Methods:

  • Review of physical, chemical, and enzymatic decellularization processes.
  • Analysis of how different methods affect tissue composition and structure.

Main Results:

  • Decellularization efficiency depends on tissue origin and chosen methods.
  • Treatments alter the ECM scaffold's biochemical composition, ultrastructure, and mechanical properties.

Conclusions:

  • Understanding decellularization effects on ECM is crucial for successful regenerative medicine applications.
  • Method selection critically influences the biocompatibility and efficacy of the resulting scaffold material.
