Stem cells are that special class of undifferentiated cells that have the capacity to differentiate into any specialized cell types. Stem cells can be obtained from two common sources – embryonic stem cells and adult stem cells.
How Stem Cells Can Cure Diseases?
Stem cells are very different from other types of cells found in human body. All types of cell ceased to grow or divide after a specific time frame but stem cell is an exception to that. They have the power to divide and renew themselves for longer period of time. Stem cells are unspecialized but surprisingly they can develop themselves into specialized cell types. Modern science is trying to utilize this special characteristic of stem cells to replace damage cells with new cells to treat a disease.
What are Induced Pluripotent Stem Cells?
Induced Pluripotent Stem Cells (iPSCs) are basically the adult cells that have been reengineered genetically to reach an embryonic stem cell-like state. Adult stem cells are being forced to express genes and factors important to maintain a set of properties of embryonic cells. iPSCs are the useful tools for developing drugs and modeling of diseases . Scientists are hopeful in using them in transplantation medicine.
How Effective Is the Stem Cell Therapy in Treating Diseases?
The best-known and most extensively used stem cell therapy is the hematopoietic stem cell transplantation. For example, bone marrow transplantation is a kind of stem cell therapy which treats certain blood and immune system disorders. It also helps in rebuilding the blood system after undergoing specific kinds of cancer treatments. Stem cell grafting or implantations are also being used to treat some bone, skin and corneal diseases and injuries. Stem Cell Therapy Montreal are well equipped to offer effective treatments for orthopedics, neurological, cardiac pulmonary and autoimmune diseases.
Can a Single Type of Stem Cells Cure Different Types of Diseases?
Not all stem cells come from a single part of a body. Different types of stem cells have different places of origin and they serve different functions. Stem cells have healing property but it is impossible to achieve without manipulation in laboratory. Without any manipulation tissue-specific stem cells can generate only other cell types found in the tissues where they came from. So, different types of stem cells are required to treat different types od diseases.
Are the Stem Cells Derived from Own Body Safe for Treatment?
Theoretically, our immune system is designed in a way that does not attack cells of our own body. During autologous transplant therapy, cells derived from patient’s body have to be processed, grown and reintroduced into the body. As soon as the cells are removed from the body, there is a risk of contamination because of bacteria, viruses or pathogens. Reintroduction of contaminated cells can cause diseases or interfere with normal functionality of the body. To eliminate this risk, medical procedures should be carried out in stringent lab conditions.
Stem cell therapy surely marks the advent of new era in healthcare sector but we should me more cautious and informative regarding the treatment procedure.
