Stem Cells - Fundamentals
Frequently asked questions
The body's specialized cells which are damaged or diseased cannot be replaced by natural process. Stem cells can be used to generate healthy specialized cells and can be transplanted to diseased or diseased cells to grow normally.
In cell therapy the diseased cells are replaced by healthy stem cells, which is similar to organ transplants in which the diseased organ is replaced by healthy organs. There is currently acute shortage of organ donors, stem cells can serve as a very useful alternative by regenerating the damaged organ.
What Is Myoblasts Transfer?
In a clinical trial in boys with Duchenne muscular dystrophy (DMD), the immature muscle cells (myoblasts) are removed from close male relatives who do not have DMD, and are transplanted directly into the boy's muscles. The transferred myoblasts regenerates the boy's damaged muscle.
What Are The Problems During Storage Of Cord Blood?
Some stem cell banks store the whole blood samples, some banks separate the red cells, white cells and other blood components and the cells are freeze stored.
What is Stem cell Homing?
When the healthy stem cells are transplanted into the vein of the patient, these stem cells are capable of finding their path into bone marrow, this process is called stem cell homing.
Are Some Kinds Of Stem Cells Better Than Others?
It is desirable to have a stem cell that has the ability to form different types of cells, which can be used to replace damaged tissue. Mouse embryonic stem cells can produce any tissue required in the adult mouse. Pluripotent stem cells in the human embryos have the same property.
It is not clear whether stem cells from adult tissues or umbilical cord blood are pluripotent. The comparison of human embryonic stem cells to adult stem cells is currently a very active area in research, and one that will hopefully lead to cures for tissue degenerative diseases in the future.Is clamping of cord blood harmful to baby?
Clamping cord blood soon after delivery will not harm the baby.
Clamping the blood is safe and reduces the risk of developing diseases (hypervolemia, polycythemia, hyperbilirubinemia).
Additional blood may be required for babies who have lost blood through birth canal.
