Foregen was brought into existence by its founders’ desire to harness regenerative medicine’s amazing advances over the last fifteen years. Under certain circumstances, dermal replacement techniques can now restore original tissue to those who have lost it.
Below is a brief explanation in layman’s terms of the process of regeneration, and, for reasons of space and practicality, is not a scientifically complete one. For more complete information on the science of regeneration, follow the links that are embedded throughout this page.
Those who have time, read below. For those who don’t, here’s a quick video (3 minutes) on regeneration.
Regeneration was recently featured on “60 Minutes” – click here to watch.
Regeneration is the ability of the body to regrow tissue when it is lost by trauma, disease, or other misadventure. The most famous example of this is the salamander, which can reproduce whole arms, legs, tails, and other body parts within days following their amputation. Salamanders are, however, not the only creatures with such powers - humans have them naturally as well (at least for a time) while developing in the womb. If a developing baby loses a finger or another of its extremities, it simply grows it back without forming scar tissue. Indeed, very young neonatal babies can sometimes do the same if injured shortly after being born. Even in adults, kidneys and livers retain some of this regenerative capacity when they are damaged.
While we don’t know fully why we cannot regenerate after birth, existing theories may shed some light on the issue.
One theory is that stopping the regenerative process is critical to allow a much more powerful survival aid to take its place: scarring. A scar allows a wound to seal quickly, thus preventing death from infection or loss of blood. In evolutionary terms, the ability to scar helped our ancestors survive. Put simply, for primitive man there was little benefit in having a body that regenerated an amputated arm (which takes months) if, in the meantime, he bled to death. Survival by scarring was, therefore, a critical step forward in evolutionary terms, not just for man but for all mammals.
Scarring is not without costs, however. First, scar tissue inhibits any new regrowth by regeneration; and secondly, scar tissue is inherently different from the normal tissue that once was there (as anyone with a scar will know), both in appearance and in function. It stops us from dying when wounded, but is useful for little else functionally.
That is the question to which biomedical research has devoted itself for many years. Fortunately, we now have some answers. The first is the discovery that the unique DNA structure present in every cell represents (among other things) a blueprint or map of our whole body, not just information relevant to that cell. This blueprint organizes the body’s growth in the womb by telling cells what comes next in the growth process. This body map is created in the very first cell we have and remains constant throughout our lives, unaltered even if our body becomes wounded, damaged, or amputated in some way. As such, when we are wounded, our body still has a record of what should have been there, a record that regenerative medicine uses to have the body remake itself.
The second key is learning how to stop scarring from happening. When we are wounded, our body automatically instructs the cells at the wound site to form scar tissue. As stated above, this function was of importance to evolution but marked the end of natural regeneration in our body. Regenerative medical techniques have shown that it is possible to turn off that instruction from the brain and instead send a new instruction to wound site cells to regrow what was taken away, using the blueprint present in our DNA, just as if the body were still in the womb.
There are two critical elements in regeneration: stem cells and the extra-cellular matrix or ECM. Of course, you have heard of stem cells. Traditionally, stem cells were derived from aborted fetuses, which is why so much controversy surrounded them. Recently, scientists discovered a simple method to revert adult skin cells back to embryonic stem cells. This is a feat that cannot be overstated. The less familiar term, the extra-cellular matrix, is also a necessary component for regenerating tissues. The ECM can be thought of as the skeleton for a tissue. It provides an attachment point for cells and gives structures their three-dimensionality. It also facilitates cell-to-cell communication and stem cell differentiation as well as providing the necessary vascularity to nourish cells and remove waste. When implanted correctly in the human body, the ECM prompts the surrounding cells to repair the tissue instead of creating inflammation and scar tissue. The ECM can be engineered, usually with a 3D printer, or obtained by stripping the cells of a donated tissue with specialized detergents. (To read more about the current progress of bioprinting, click here)
The standard practice in regenerating a tissue is to obtain the ECM of the tissue you wish to regenerate and then seed it with the appropriate layers of cells. The experiment is confined within an environment that mimics that of the human body until the cells populate the entire structure. Each particular tissue has specific needs in terms of cells and growing environment, but this general model has proven extremely successful in regenerating even the most difficult of organs, such as the heart, liver, and kidneys.
These feats convince even the biggest of skeptics that Foregen’s mission to regenerate foreskins and reverse circumcision is possible. We know the technology exists. In fact, we have made tangible progress towards it. The main obstacle in achieving foreskin regeneration is aligning the overwhelming demand for a cure for circumcision with the correct scientific personnel. That is why Foregen was founded, and that is what Foregen will achieve.
This is a wonderful question and one that Foregen takes very seriously. Foregen deeply respects the efforts of all the dedicated scientists in the biotech world and recognizes the importance of their work. There is no question that a patient needs working vital organs before fully functional sexual organs to survive, but there are legitimate reasons to pursue foreskin regeneration that will benefit all aspects of the field of regenerative medicine.
First and foremost, the demand for a cure for circumcision is overwhelming. The body part that is in highest demand for regenerative purposes in the US is the kidney. About 100,000 people are on the waiting list for one. There are approximately 1,000 times as many men (100 million) who are in need of an intact penis in the US alone! Although not all of these men are aware of Foregen’s existence yet, or even of the damage imposed upon them, they soon will be as we make progress towards regeneration.
Another major benefit that foreskin regeneration will bring to the field of regenerative medicine is attention. When we are successful, regenerative medicine will be brought into the public eye because of the tangible and intimate effects our therapy will provide for millions of people. This newfound attention will foster further interest, investment, and progress in the field.
And lastly, we at Foregen believe there is a difference between surviving and truly living. To live, one needs to be physically, mentally, and spiritually healthy. A healthy sex life is an integral part of any person’s overall well-being. Since circumcision amputates a significant amount of skin, nerves, and function from the male sexual organ, it is necessary to reverse this damage to regain a complete sex life and with it, a newfound appreciation of life itself.
Yes, both Foregen and Anthony Atala’s lab (indirectly with his rabbit experiment), have made progress toward foreskin regeneration. However, no clinical trial has ever been done with the purpose of restoring a foreskin to a circumcised man, yet. However, foreskin fibroblasts, that is, small samples of foreskin tissue, have been successfully used in many medical experiments to generate new skin (it should, however, be stated that some of these experiments were, in Foregen’s view, unethical as they involved foreskins taken non-consensually from healthy infants circumcised without their consent. Foregen is not, and will never be, involved with such experimentation). Foreskin has proved exceptionally fruitful as a regenerative agent, making the likelihood of real foreskin regeneration in vivo, on a living male, all the better.
Very soon, we hope! We already have the ECM for regenerating animal foreskin. We must finish publishing the results from our first experiment before we move onto fully regenerating these foreskins. Also, we have already been approved by an organ donation organization to acquire human adult foreskins upon which we will conduct the same regenerative experiments as the animal foreskins. In the short term, we hope to fully regenerate human foreskins. Once we have accomplished that, our goal is to advance onto human clinical trials as soon as it is safe to do so.
We believe so. In other regenerative surgeries, the new tissue reintegrates itself into the body, which recognizes the tissue as its own and does not reject it via the immune system as it would for grafted skin or transplanted organs. Those who have already undergone regenerative therapies have had amazing success. For example, those who have received regenerated bladders or tracheas, as mentioned earlier, now have fully functioning organs! The nerve connections severed by the trauma of the surgery (in our case, circumcision) were reconnected to the body with the new implanted tissue. We expect Foregen to achieve similar results in our clinical trial.
