Naturally occurring stem cells in the body. There are blood cells, nerve cells, brain cells or other cells. In fact, no identity, at least not yet. However, you can develop into different types of cells to replace damaged cells, were not to know how defects. You have the ability to clone and make more stem cells. Adult stem cells, tissues and organs of adults present, and as always, the life of the individual with the needs of its members updated to replace damaged cells need. It is this fact that has caused the researchers suspected that stem cells could correct the hearing loss.
When the outer ear picks up sound waves travel through the air and then move into the ear canal, said the hearing would take place. This is the tympanic membrane (eardrum) and three small bodies, ie the stirrup, the hammer and the anvil. There is also the cochlea, a snail-shaped organ that contains beautiful hair "type of nerve fibers into electrical impulses, which are in turn transmitted to the brain, the sound waves. The hair is" How are the nerve fibers are very sensitive and can easily damage or accidents with loss of hearing due to age, disease, noise and other non-medical "condition.", most often permanently, the results of nerve damage.
In this sense, the School of Medicine, Indiana University, Dr. Hashin Castor, Ph.D., of the set of instructions to see if it can be converted in the sensory nerve cells, nerve cells called neurons. It is from nerve cells in mouse bone marrow derived and translated into many properties similar to neurons. Neurons transmit sound from outside the brain in processing of sound and interpretation. These results suggest the possibility of re-election to replace the growth of bone marrow stem cells to damaged neurons.
Said Dr. Hashin your interest in bone marrow cells, which, because of their potential therapeutic use of autologous cells (cells used from the patient in the treatment of some patients.) Use of bone marrow cells ideal can be easily collected and stored in the living laboratory until needed.
Around the same time, the experience of the new study Dr. Hashin Tokyo. These studies show that bone marrow cells injected into the ear damaged Hörerholung after partial hearing loss of speed on stem cells. This suggests that some will want "the fibroblast growth factor artificial cochlea, these cells can be destroyed. However, only a partial recovery of several weeks to look at, but the trauma patients with hearing loss is often never lose the ability to hear high frequencies.
Research on efficient use of stem cells for patients to restore or improve hearing has begun.
Animal studies indicate that the potential for regeneration, the conversion of the nerve by electrical impulses to the brain is followed by the sound waves. Today is the future to recover the sense of hearing to those who have lost or are losing their meaning is clear.
