ABSTRACT
Organ transplants are a complex medical intervention that
allows for the replacement of organs damaged due to chronic
or traumatic diseases. This process includes donor selection,
recipient evaluation, extraction, preservation, surgery,
and post-operative care. Immunosuppressants are key to
preventing acute or chronic rejection. However, despite medical
advancements, the demand for organs exceeds the availability,
with thousands of patients on waiting lists. Xenotransplants,
such as porcine pancreatic islets, have emerged as a promising
alternative, especially for treating type 1 diabetes and reducing
insulin dependency. Additionally, genetic engineering has
enabled the modification of pig organs to avoid immune
rejection in humans, as seen with CRISPR (Clustered Regularly
Interspaced Short Palindromic Repeats)-edited kidneys. In
summary, tissue engineering has also advanced, allowing the
creation of functional organs from stem cells. These innovations
offer hope to overcome the increasing organ demand and
improve the quality of life for patients in need of a transplant.
