Stemcell – The Definition
Stem cells are the origin substance of our bodies. These are the parent cells which generate the other cells in our body with specialized functions. In the beginning phase of anatomy, there is only one stem cell. This stem cell further develops various cells which are referred to as their daughter cells. These daughter cells can be regenerated under precise conditions either naturally or prosthetically. In some cases, these daughter cells become stem cells or a specialized cell which develops with more specific functionalities such as heart muscle cells, blood cells, brain cells, etc. No other cells than stem cells have this kind of specific ability to generate new cells. This incredible ability of Stemcell has opened up the gates of the Future of medical science.
The Embryonic cells are examples of stem cells. The origin of these cells is embryos. The lifespan of these cells is usually three to five days. Afterward, these cells divide themselves to become any type of cell in the body or reproduce another stem cell. The adaptability of these cells allows them to the regeneration/reparation of diseased tissue & organs. While, adult stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Only these stem cells can give rise to various cells of our bodies.
Stemcell therapy – The Future
Based on these special abilities of stem cells, the researchers had invented the regenerative type of medicine, called Stem Cell Therapy. The stem cell therapy is able to repair the injured tissues and cure disease. You may call this therapy the next level of organ transplantation in which, stem cells can be used instead of donated organs. This stem cell therapy has emerged as a blessing in medical science by fulfilling the shortage of organs.
In this therapy, the researches grow these stem cells by creating a specific artificial environment. This environment manipulates the stem cells to specialized to perform a specific function. Then after they injected these stem cells in our specific body part. For example, if a patient is suffering from heart diseases. The stem cell is injected into his heart muscle. Later on, these stem cells contribute to repair his heart muscle by generating other heart muscle like themselves.
Stemcell therapy – Modern Achievements
Nowadays, the doctors have moved on to a new stem cell transplant technique, known as bone marrow transplantation. In this technique, the implanted stem cells alter the cells, damaged by chemotherapy or disease. Sometimes, these stem cells help the donor’s immune system to fight against some types of cancers or blood-related issues like lymphoma, multiple myeloma, leukemia, and neuroblastoma. The bone marrow transplantation technique uses adult stem cells. In addition to that, the researchers are testing the adult stem cells to treat in the extreme condition of the patient such as heart failure.
Stemcell therapy – In Future
For the future, the researchers are doing further research on futuristic stem cell transplantation. They call this technique “Therapeutic cloning” or “Nuclear transfer”. In this, they are trying to create a versatile stem cell that is independent of a fertilized egg. By using this technique, they will replace the nucleus of the unfertilized cell with the nucleus of the stem cell. These stem cell nuclei will then divide itself to form a blastocyst. This process will create a line of stem cells that is genetically identical to the donor’s cell-like clone. Some researchers believe that this technique may allow them to see how diseases develop. That’s why Stemcell technology can become the Future of medical science.
