Injectable materials for adipose tissue engineering are crucial for long-lasting soft tissue fillers. Current fillers are temporary, highlighting the need for materials promoting natural fat formation and reducing repeat injections.

Area of Science:

  • Materials Science
  • Biomedical Engineering
  • Regenerative Medicine

Background:

  • Soft tissue fillers are increasingly used clinically, but existing injectable materials have limited longevity due to rapid resorption.
  • Current fillers are temporary and cannot promote natural adipose formation, necessitating repeated procedures for sustained effects.
  • There is a significant need for injectable materials that function as fillers and actively promote in vivo adipogenesis.

Purpose of the Study:

  • To review the advantages and disadvantages of currently marketed soft tissue fillers.
  • To summarize research on injectable synthetic materials, biopolymers, and extracellular matrix-derived materials for adipose tissue engineering.
  • To outline successful attributes, current challenges, and future directions in injectable adipose tissue engineering.

Main Methods:

  • Review of commercially available soft tissue fillers.
  • Summary of current research on injectable synthetic materials for adipose tissue engineering.
  • Analysis of biopolymer and extracellular matrix-derived materials in adipose tissue engineering.

Main Results:

  • Commercially available fillers often exhibit limited longevity and do not induce natural adipose tissue formation.
  • Injectable synthetic materials, biopolymers, and ECM-derived materials show promise in promoting adipogenesis.
  • Successful material attributes include biocompatibility, biodegradability, and the ability to support cell infiltration and differentiation.

Conclusions:

  • Current injectable soft tissue fillers are largely temporary due to rapid resorption and lack of adipogenic potential.
  • Advanced materials, including synthetics, biopolymers, and ECM-derived substances, are being investigated to overcome these limitations.
  • Future research should focus on developing injectable materials that promote sustained adipose tissue regeneration and long-term clinical efficacy.
