Main Methods:

  • Review of current understanding in biomaterial biocompatibility, preservation, and surface tailoring.
  • Case study on the derivation of vascular grafts from human umbilical cords.
  • Analysis of Wharton's jelly potential for applications like biolubricants and wound healing.

Main Results:

  • Successful derivation of limb salvaging vessels from human umbilical cords for arterial reconstructive surgery.
  • Identification of numerous opportunities for product development from Wharton's jelly.
  • Demonstration of surface modification as a critical factor for beneficial tissue interaction.

Conclusions:

  • Natural materials, with appropriate surface modification, are increasingly viable for biomedical applications.
  • Wharton's jelly presents significant potential for diverse biomedical product development.
  • Bioadhesion principles offer a predictive framework for biomaterial behavior in various physiological and environmental settings.
