Though found in different areas of the animal kingdom, the degree to which humans can regenerate limbs, organs and tissue due to serious injury is very low (one exception is the liver), especially compared to animals like the amazing Axolotl. Scientific research into using 3D bioprinting to re-create and regenerate human limbs and organs from patient-specific DNA is progressing slowly but surely.
The implications and potential for organ transplant patients with life-threatening prognoses is profound. Even when there is an organ donor match for patients in need of a transplant, rejection by the host of the transplanted organ Is a constant threat to completed surgery. Organ transplant patients undergo rejection prophylaxis, which involves taking a suite of medicines for the purpose of preventing or reducing organ rejection. If surgeons and medical professionals could offer patients a “copy” of their organs based on their own DNA profiles, rejection prophylaxis could become unnecessary.
