One issue that affects many around the world is lacking access to enough organs for transplant. Over 17 people die every day because they cannot receive a life-saving organ transplant on time. And with over 100,000 people waiting on the recipient list as of May 2025, this is a serious issue for people and their families. Still, there is a solution on the horizon for this problem, and that is lab-grown organs.
Laboratory-grown organs, also known as bioengineered organs, are cultivated with cells from the recipient patient. It is feasible with this for organ acceptance to be a perfect process with a rejection of the organ not happening at all. The process is done through 3D scaffolding that mimics the structure of the desired organ whether a heart or a kidney. Stem cells are later added for cultivating useful tissue for the organ. And with 3D bioprinting, scientists are able to create these various organs through layering and structuring cells.
This technology has also been successful through trials. Research has shown where a patient with a transplant for their bladder had it work. It shows promise for this technology being used on a larger scale down the road. Also, a team at Wake Forest Institute for Regenerative Medicine, back in 2023, had performed a trial where they tested lab-grown liver cells into animals, which shows this technology is not far away from being a reality for human patients with life-sustaining transplants.
In addition, it would do away with donation and rejection problems. The benefits far-reaching aside from a possible solution for the serious shortage of donors, a built organ would be custom-made for the patient, may not involve prophylactic drugs and associated complications.
Yes, there are still barriers. Creating these organs on a large scale, having them work for extended periods, and gaining regulatory approval are all huge hurdles. Still, what has been done is encouraging, and potential is enormous.
Organ growth in a laboratory is not just a matter of technology—it’s a matter of giving people a second chance at living. It will one day make organ shortages a thing of the past and open up a whole new dimension for medical practice. It’s not all about organ substitution—it’s about giving hope to millions.
