Recently I have been curious about stem cells, and gain more knowledge of how they work. Asking what are they? Where do they come from? And what do I know about them? Knowing these amazing stem cells live inside our bodies. Sighted it as an atomic world, demanding and complex like the world we live in. Stem cells construct and preserve this microscopic world. Life starts with one cell, as we know the fertilized egg. During development, cells divide constantly to produce a multitude of cells that construct our body. At a definite phase, utmost cells stop making reproductions of themselves and start to specialize. Which at this stage we are completely formed in specialized cells. These specialized cells are characterized either to carry oxygen through our blood system, extending and contracting our muscles, transmit messages between the brain and throughout the body.
Stem cells are extraordinary cells because the specialized cells can no longer duplicate themselves. If the specialized cell is insubstantial, to be replaced from somewhere. This is where stem cells function is then taking place to replenish damaged cell like the blood system. Our body replenishes millions of new blood cells contently and replaced with generated from bone marrow stem cells. Blood stem cell can create eight special types of specialized cell. Skin cells are in consent cycle of restoring tissue underneath the dermis layer and out to the epidermis. Not only do we have this amazing understanding of skin cells there is not more discovery that is our brain has the same function of creating new stem cells in addition. Scientist is grasping the understanding of why stem cell has to form a superior function of purpose.
Scientists continue to observing the produces with two daughter cells which can create new stem cells or specialized cells. Stem cells in the adult tissues can only make the type of cell in tissue, stem cell in the skin can make cells in the skin, but it can’t make blood cells. Stem cells are now beneficial in medicine. Single skin stem cell independently can produce plenty of specialized skin cells to cover the entire body. The new studies resulted in a breakthrough in treatment for patients with extensive burns. This procedure takes a sample from an unburnt area of the skin with microscopic cellular separation of the inner cell mass then is isolated in a flask container with specialized liquid this contains protein and sugar to feed the cell. In time the cells will multiply inside the flask.
Next will remove a sheet of the skin cell using a special liquid chemical and transplant it on the patient. Which we all know we need the first layer of our skin to protect. But the downfall is doctors cannot reconstruct sweat glands or hair follicles. In result patient’s lives are saved but can’t have a normal body function. Scientist doesn’t stop there, more studies not yet to be done. Laboratories are demanding to fathom how the skin is built to be able to reconstruct it in the lab. So doctors are able to improve the lives of these patients. Leukemia is one blood disorder used to treat patients with stem cells by a transplant limited blood stem cells enough to restore the entire blood system. Stem cells for specific tissues and organs can only make the cells of that tissue stem cell. Stem cells are only specialized to differentiate in skin, blood, guts, and muscles, but studies are unknown whether other organs have their stem cells. Reverting the sequence of stem cell development, there may be a missing link of another type of cell that could answer the meaning of existents. The embryonic stem cell comes from a blastocyst, the stage of development before establishment in the uterus.
On behalf of fertility treatment, blastocysts are produced in the laboratory. Early embryo development, there are specialized groups of cells that can differentiate to entirely tissues of the body. These are the cells doctors and scientist are very interested in, scientist investigation carries on in taking the cells from the early embryo and grow then in civilization and is maintained at that time where cells can contribute to all the tissues. Microscope blastocyst stage of development is removing from the trophectoderm cell so what is left with the inner cell mass. Which then is grown in refined to multiply cells to form any tissues at all. Embryonic stem cell can become heart, blood, brain or skin cells this is depending on the way stem cells are developed what they are equipped to do what they are meant to do. Scientist goes through a continuous series of studies of what specialized cell which a combination of internal and external indications performance each stem cell path towards specialization provided by the body. Figuring out how to reconstruct these indications in the lab, scientists’ goal to grow a pure population of almost any cell type. The challenge scientist is to understand each resolution and skillful stem cells have. In what way are the signals delivered to enforce the path stem cell are categorized. When this is understood then you suddenly see that you could use it to report medical condition and complications. A new breakthrough that has been recently making stem cell for the brain by using embryonic stem cells which is successful. By this time the neural stem cells are now no longer able to make all cells, just three types of cells that exist in the brain. This result is an important revolution for scientist to create a useful and powerful system, which can both be applied for drug screening and transplantation. With all the advance studies of stem cell are helping scientist understanding more about what goes wrong in complex diseases like diabetes, Parkinson’s and Alzheimer’s.
The pancreas is cells isolated for donor organs which will become cells to normalize diabetes and is corrected. Major obstacles to beta cell transplantation in diabetes is, of course, the shortage of donor cells. Which can be transplanted so few per year, where thousands can only be treated with insulin. Which scientist has to look at other techniques to produce insulin-making cells in the laboratory. More studies have to be done between the two different stages of stem cells to the beta cell which is then isolated and grown in the laboratory to produce more insulin cells which are the goal. The embryonic stem has been the highlight for a scientist to open a new world of regenerative medicine, which need to be examined very carefully. Stem cells research is a fast-moving field. Around the world, new findings are constantly reported, creating new questions and fresh challenges for scientists seeking to harness these cells and to shape future medicine. In development, the cells have to make choices and decide to become different types of cell, and understanding how that is controlled how that decision is made. If understanding that it seems we understand the most important thing about life.
