How will it be to form a new regenerative therapy using stem cells to have control over gut microbes? This would open up many doors to tracing the roots of various diseases caused due to gut microbes. This is how scientists at the University of Toronto are devising a tailor-made gut-inhabited microbe to release drugs when instructed.

The team led by associate professor David McMillen is on their quest to develop regenerative medicine therapeutics to discover etiologies of intestinal diseases. In order to do so, they are eyeing to put an engineered bacterium into the gut to detect the source of different diseases occurred by the gut bacteria.

Intestinal stem cells are like progenitor or hematopoietic stem cells with an ability to proliferate and differentiate, and they are well-endowed with self-renewal capacity. Hence, when there are a wear and tear in the intestinal tissues, they can easily manage the damaged tissues through self-renewal capacity. Taking this into account, the scientists are collecting intestinal stem cells for regeneration in a culture dish, aiming to improve their capacity of natural healing power in the body, and also foster the tissue regeneration for replacement.

The discoveries of science have us going surprised by its amazing traits and functions inside the body. Much to our surprises, nearly 100 billion cells confront an exit every day through an intestine as a result of extreme wear and tear, which occurs due to the digestion process in the body. However, due to these lost cells, we do not suffer any extreme health condition unless something goes wrong with the entire physical systems. We must thank to stem cells to replenish all these lost cells in collaboration with the intestines, and lend their assistance in repairing damaged tissues. However, when stem cell therapy cannot provide its support for tissue repair, we can suffer from a range of diseases from inflammatory bowel disease to cancer.

The prevalence of inflammatory bowel disease or IBD is quite high among the children aged fewer than six. Adults are also not safe from various types of IBD like Chron’s disease or ulcerative colitis, impacting heavily on the quality of the lives of every person suffering it.

• Stem Cell Transplant At The Rescue Of Acute Myelofibrosis

Replacing damaged or malfunction cells in the intestines are the normal functions of stem cells. However, the cells in the intestinal lining do not get any replacement, it is to create a hole in the gut, and as a result, the leaky gut cannot digest food properly, detoxify the wastes and ward off microbes from the gut. Therefore, the gut becomes vulnerable to developing IBD.

The microbiome- the resident gut bacteria, often considered as a neglected organ is one of the crucial parts of our bodies to help us tackle many diseases by boosting our immune system. Hence, scientists inserted engineered gut microbe into the lining of the gut wall so as the manipulated microbe can detect an inflammation and possibly help find ways to treat and even cure IBD.

In addition, the gut bacteria are wired to secreting an enzyme called muramyl dipeptide (MDP), which makes a connection with receptor NOD2, residing in the stem cells. As per reports, this enzyme works in compliance with this receptor to influence intestinal stem cells to divide and create new cells for lining repair.

It is likely to manipulate the gut bacterium to increase the production of MDP enzyme so as to curb the inflammation in the intestine. It is possible to trigger human receptors to urge stem cells so that they can double the healing of the gut lining and cure Crohn’s disease.

From the study, we can hope for a fruitful approach in the future, which can better health using stem cells and the regenerative therapeutics and medicines. The days are not so far when we can achieve relief from these debilitating conditions with ease. And credits remain at the foot of stem cells. 

We know how regenerative therapy has proven a boon for medical applications in the real-time clinical settings. The basic of the tissue engineering is nothing, but the cell-based techniques using stem cells. Although there are different sources to harness stem cells, one of the primary sources to derive stem cells is adipose stem cells.

Stem cells work at the cellular level by following proliferation and division techniques. When there is a wear and tear in the cells, stem cells tend to repair that damage and heal itself at a faster rate.  The healing of the particular cells is undertaken when the DNA confirms the damage in the particular site and instructs stem cells to use its reparative potentials.  Hence, the malfunctioning of the DNA interrupts the healing and regeneration process by stem cells, and no cure actually takes place. In that particular case, when our physical system loses its potential to heal and regenerate tissues following the stem cell proliferation and division, the entire works rest upon the regenerative therapy.

The regenerative therapy is a cell-based therapeutic, aiming at repairing and regenerating damaged tissues in the body.

When our body becomes matured, a significant trade-off mechanism is built. A matured cell tends to lose its capacity of the division, but it can specialize later. Muscle or tissue regeneration is necessary for life to sustain. Muscle cells, for example, can only contract since they are able to contract only. If all our muscles were specialized, we would have lost our potentials to proliferate, and as a result, our tissue cannot regenerate. Hence, this is a huge life-threatening risk for us. However, our body does not have to follow this risk as we tend to store a small number of stem cells, which are able to divide and replace damaged tissues.

Due to the specialized character of the stem cells, these elements are widely used for the tissue regeneration using the harvesting method from the donors. So, once they are harnessed, they are implanted in the patients to enable the tissue engineering procedures. However, this process does not work for those, who are infected with genetic degenerative disorders. People suffering from this ailment cannot donate their stem cells as they are useless for causing repair in the natural manner.

Hence, it is highly deemed fit to collect stem cells from someone healthy.  And therefore, the collected tissues once implanted are able to regenerate a healthy and populated tissue in the affected area.

At the same time, the collected stem cells can be manipulated to engineer into a required tissue in a petri dish in a lab. In this case, the cells are reprogrammed to mimic the normal tissue functioning so that they can divide and specialize into the tissue for the transplant. Burn injuries, for example, need harvested stem cells to grow the tissues in the lab for an implant. The process of tissue regeneration for burn victims are referred to as skin grafts.

Therefore, stem cells can provide immense advantages for medical research and applications to treat genetic disorder as well as different physical ailments. We are thankful to the scientists that they are quite knowledgeable about the use of stem cells in the regenerative therapy. 

It is not hidden to any of us that regenerative therapies are based on stem cell clinical techniques. There is a wide range of sources like adult mesenchymal stem cells, embryonic stem cells to harvest stem cells. However, the most accessible source is the fat-derived adipose tissue to harness stem cells for the procedure of regenerative therapy. Since these fat cells are huge resourceful, stem cells can be collected at any time from any part of the body.
