Xenotransplantation

Xenotransplantation

  • In the first-ever transplant of a gene-edited pig heart to a person, the genetically altered pig heart pumped more slowly than usual. Only 61 days passed following the transplant for the human recipient.
  • Such transplant attempts in the past have likewise failed.

Describe Xenotransplantation.

  • The transplantation of animal tissues or organs into human recipients is known as xenotransplantation.
  • Gene editing was used in a recent pig-to-human heart transplant to eliminate sugar from the cells that cause incredibly quick organ rejection.
  • A collection of scientific techniques known as genome editing, sometimes known as gene editing, allow researchers to alter an organism's Deoxy-Ribonucleic Acid (DNA).
  • Organ rejection is among the largest barriers to transplantation.

Importance:

  • This development may help us get closer to finding a solution to the world's organ scarcity.
  • Patients in India require between 25,000 and 30,000 liver transplants each year. However, only approximately 1,500 people really get them.
  • Pigs are becoming more and more common organ transplant recipients.
  • Pigs are easier to nurture and grow to adult human size in just six months, giving them an edge over primates for the purpose of harvesting organs.
  • The anatomical and physiological characteristics of pigs are comparable to those of humans, and pig breeding in farms is a common and economical practise.
