Nationality and Profession(s)
British, Developmental Biologist
John Gurdon's career spans over five decades, with a focus on developmental biology, stem cell research, and the study of gene expression. He is widely recognized for his contributions to our understanding of cellular development and differentiation.
Early Life and Background
Gurdon grew up in London, England, during World War II. His early life was marked by the challenges faced by many families during this period. Despite these difficulties, Gurdon's parents encouraged his interest in science and education. He developed a strong foundation in biology and mathematics at school.
Major Accomplishments
Gurdon's work has been instrumental in shaping our understanding of stem cell biology. One of his most notable achievements was the discovery that mature cells can be reprogrammed to become pluripotent, meaning they have the potential to develop into any cell type in the body. This finding, known as nuclear transfer or cloning, revolutionized the field of developmental biology.
In 1962, Gurdon's laboratory at Cambridge University made a significant breakthrough when they successfully cloned tadpoles using nuclear transfer. This pioneering work demonstrated that mature cells could be reprogrammed to become stem cells, paving the way for future research in regenerative medicine and tissue engineering.
Gurdon's contributions have been recognized with numerous awards, including the Nobel Prize in Physiology or Medicine in 2012, jointly awarded with Shinya Yamanaka. This prestigious honor acknowledged their work on the discovery of how cells differentiate and develop during embryonic development.
Notable Works or Actions
Throughout his career, Gurdon has published extensively on topics related to stem cell biology, gene expression, and developmental genetics. His research has been instrumental in advancing our understanding of cellular differentiation and reprogramming.
In addition to his scientific contributions, Gurdon has also served as a mentor and advocate for the importance of basic scientific research. He has held various positions within the scientific community, including serving on the editorial boards of several prominent scientific journals.
Impact and Legacy
John Gurdon's work has had a profound impact on our understanding of stem cell biology and its potential applications in medicine. His discovery of nuclear transfer and reprogramming has opened up new avenues for research into regenerative medicine, tissue engineering, and cancer treatment.
Gurdon's legacy extends beyond his scientific contributions. He has inspired generations of scientists to pursue careers in developmental biology and related fields.

Quotes by John Gurdon
The first point to remember is that attempts to clone mice have actually been very unsuccessful for at least a decade. Sheep have been successful. So one asks, 'Where do humans lie?' Most people think they are somewhere between the two, but at least there's a reasonable chance they might be clone-able.
The earliest example known to me of replaced body parts is exemplified by a Mayan skull dating back to 1400 BC. In this skull, false teeth made of stone had been implanted.
The importance of the egg's non-nuclear material - the cytoplasm - in early development is apparent in the consistent relation that is seen to exist between certain regions in the cytoplasm of a fertilized egg and certain kinds or directions of cell differentiation.
For my part, I have worked all my life with eggs and embryos of frogs. Compared to other small animals, these have figured prominently in the world of literature.
I myself have been a major beneficiary of the view that no animal will more repay treatment that is kind and fair.
If you took some famous religious leader, for example, and said it would be nice to clone them indefinitely so you have a dynasty of leaders, my own guess would be that each time the cloning takes place, they would become more and more defective, presumably mentally defective and subsequently worse.
I have this rather amazing report which, roughly speaking, says I was the worst student the biology master had ever taught.
I remember that, at an early age, I spent many months making a three-masted sailing boat with rigging in a half-walnut shell.
In principle. what is done is to take the nucleus out of a cell with a very fine micro-pipette or needle and introduce it into an egg. That had been done with amphibians a long time ago, and then there was a long pause of many years before people were clever enough to make that work in the sheep.
If you explain to a patient what can be done and what might be the downsides, let the patient choose; don't have ethicists, priests, or doctors say you may or may not have replacement cells.
