Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Area of Science:

  • Plastic Surgery
  • Regenerative Medicine
  • Facial Anatomy

Background:

  • Traditional fat grafting has limitations in dynamic facial expressions and contour transitions.
  • Centrifugally stratified fat layers possess distinct biological properties.
  • Integrating volumetric restoration with dynamic expression via layered grafting is challenging.

Purpose of the Study:

  • To propose a dynamic assessment-multimorphological fat grafting strategy.
  • To align facial rejuvenation with biomechanical principles.
  • To develop personalized rejuvenation protocols.

Main Methods:

  • 305 patients (19-56 years) underwent fat grafting from December 2019 to February 2023.
  • Harvested fat was processed into high-density macrofat, high-density microfat, and stromal vascular fraction gel.
  • Dynamic injection into multiple facial areas, depths, and layers using specialized cannulas.

Main Results:

  • Significant improvements in facial volume, skin elasticity, and wrinkles observed in all patients.
  • Achieved rounded, youthful facial contours.
  • High patient satisfaction (95.1% satisfaction, 4.9% basic satisfaction) with no complications like nodules or cysts.

Conclusions:

  • Dynamic multiform fat grafting is highly effective.
  • The technique yields natural and harmonious aesthetic outcomes.
  • High patient satisfaction confirms the procedure's success.
