John Gurdon’s Cloned Frogs
John Gurdon was an English biologist who was awarded the Nobel Prize in 2012 for his groundbreaking research in cloning frogs. His cloning techniques revolutionized the field of cloning, and his methods are still imposed today. So, where did Gurdon obtain the cells for cloning frogs?
Gurdon Obtained Cells from Donor Frogs
John Gurdon obtained the cells he needed to clone frogs from donor frogs. Gurdon used a process called nuclear transfer- transferring a healthy frog’s nucleus into an enucleated egg cell, thus creating an identical genetic being.
Describing a Nuclear Transfer
To better understand the process of nuclear transfer and John Gurdon’s achievements, a more detailed explanation of the process should help. First, Gurdon obtained donor cells from frogs, usually from the intestinal lining. Then, the donor nucleus from the cell was placed into an enucleated egg cell. After that, a mild electric shock was usually imposed to stimulate cell division and familiarize the nucleus with its new egg cell.
Finally, the clone of the original frog was allowed to develop and mature. It is with this process that John Gurdon revolutionized cloning to the point where it is accepted and commonplace today.
Modern Clinical Applications
Due to Gurdon’s discovery and subsequent newspaper articles, the process of cloning and stem cell research has been revolutionized. Cloning and stem cell research are now commonly accepted, and they are finding new applications, such as:
-
- Birth Defects and Diseases: Cloning can help create replacement organs and use stem cells to prevent and cure previously incurable birth defects and inherited diseases.
-
- Cancer Research: Cloning can be used to create specific cancer cells, which can then be used to study cancer and create more targeted treatments.
-
- Artificial Limbs: By using stem cell technology, artificial limbs can be created for those with disabilities.
John Gurdon’s significant contributions to cloning and stem cell research have revolutionized the way doctors approach medications and treatments for a wide range of diseases and conditions. His cloning techniques are now standard practice in research laboratories around the world.
