A Hope Of Life

Creation Artificial Organs Made From Stem Cells:

Biomedicine today involves more than a breakthrough alternative to science. It`sdisplayed as the revolution of the future. For years, people who need an organ transplant,have had to contend not only with the disease but also with many factors against him, as atransplant brings many variables that should be taken into account before doing so.

Unfortunately usually when talking about a body that does not work, there is an urgentneed to replace it with another in good condition.

But ... what brings this with him?

From this moment begins a horrific battle against time, where every minute counts. Inour country and in other countries, waiting lists are endless; and the patient needs a donor.There are few cases where a family can donate an organ to a loved one.

Why?

Whether relatives are not always compatible organs, is that as mentioned earlier is afight against a number of factors, which we need in addition to the body, it is crucial thatsupports our body, otherwise our system will reject and only complicate things. Besides thestigma that brings in itself, the fact that the existence of a donor necessarily in most cases ittakes a death, where the organs of this person remain in good condition so they can betransplanted.

Biomedicine: therevolution of the future

Over many years, this has triggered an unscrupulous underworld. On the black marketyou can find the body you want, always sold to the highest bidder. How much is the new heartof a child? What case is worth more than the heart of a child who was abducted to take awayyour heart so you will have yours? How far we get as human beings when we see that the lifeof that person we love vanishes and we cannot do anything about it? How would we act inthis desperate situation?

Apparently, if it is true that organ transplantation at the time was a great achievementfor the medical sciences, it is also true that they have not become perfect, as sometimes leadto serious problems. For this, several scientists have devoted many years of study, in order todevelop what could be envisaged as one solution "A Hope Of Life."

Today, science is facing a newdiscovery, something that could end onceand for all with the suffering of a longwaiting list, the agonizing uncertainty of whether we will or not supported. This isthe new revolution in biomedicine. In recentyears it has been discovered that stemcells are a great tool, able to providesolutions to many diseases thoughtincurable, an example of this is cancer of the bone marrow, with the foundation of aneffective treatment that has been very goodresults. In addition it has been found, it ispossible to create artificial organs fromstem cells.

There are two methods to develop a new organ from stem cells. The first is to preparethe body completely. This process does not need a donor, it is not necessary for someone todie, is to create a body from scratch. First, a synthetic structure to the exact dimensions of this body that the patient needs are required, as a new suit tailored develops. After having theexact size of the data, we proceed to the manufacture of the new body. Subsequently, thenew body is introduced into a bioreactor (this is a special container to form the body that isrequired), once this is done, appropriate air constantly bathing the new body with stem cellstaken from the patient previously, this must be made within 36 hours after that time, and thestem cells must completely cover the structure.

During this process, stem cellsremain attached to the frame and fromthere begin to form new cells arisethroughout the cell structure of a neworgan. Within two days of starting theprocess fulfilled, it has a full body as aresult, and at this point, the new organ canbe transplanted into the patient.

The other method is to obtain the basic structure of a deceased donor, this structure isextracted most of the cells until it turned into a simple biological support. Following this, theabove procedure is followed. Both methods have been tested by Dr. Paolo MacchiariniBiomedicine surgeon Karolinska Institute in Sweden. The two cases were trachea transplantadvanced cancer, for patients resulting in a second chance at life.

Although both techniques have already proven, we must now give way to time to checkthe effectiveness of these methods and see which one is the most suitable, it will eventuallybe able to determine if this new achievement does not generate new problems, so a 5-year follow frequent consultations to patients is necessary to assess in that period to which thenew transplanted organ, created stem cell recipient organism itself is, also how to determine if this new body has a limited duration. However, this finding is undoubtedly a greatbiotechnological progress, with many benefits and advantages.

If this discovery becomes a success, the risk of rejection of the new organ would beremoved, as this works with the patient's own stem cells, so the body would recognize as their own, therefore, the patient does not require medication or postoperative therapy to preventrejection. Moreover to prevent infection, as per the traditional medical system of transplantweaken the immune system prior to surgery, the patient being exposed to viruses or bacteriainfections. Another advantage is the time when the new plastic body with no need to wait the

death of another person, and not need any donor, this in turn would eliminate the blackmarket for organs. Two weeks to draft the new organ to transplant are only required and thisis vital in some cases of terminal illness.

Right now this discovery is experimental and is often a costly transplant, but this is justthe beginning of the road. There will always be the problem of transplantation to be performedimmediately in cases of emergency, but this research process continues, perhaps somedaythere is some solution for these cases. For now let's hope this important step will be backed

into a success, becoming massive practice and bringing all human A Hope Of Life.
