What are the possibilities of using human stem cells

Human stem cells can be used in different ways for research and treatment. Embryonic stem cell research can provide information about the complex events that occur during human fetal development. The main task in this area - to understand how undifferentiated stem cells become differentiated cells that form tissues and organs. This will shed light on the development of serious disorders associated with abnormal cell division - in particular, cancer and certain birth defects, and find new ways to treat them.

Stem cells are also used to test new drugs. For example, the safety of drugs can be tested on differentiated cells derived from pluripotent human cell lines. Other cell lines already used in this way. For example, a cancer cell line used for testing anticancer drugs.

Probably the most important of the potential uses of human stem cells - is the creation of cells and tissues, which could be used for cell therapy. Today to replace diseased and damaged organs and tissues used organs and tissues donors, but the demand is much greater than the supply. Control of the differentiation of stem cells may provide a renewable source of human material for transplantation, which allow to treat Alzheimer's disease, spinal cord injury, stroke effects Stroke - consequences: recovery and treatment , Burns, heart disease, diabetes, osteoarthritis and rheumatoid arthritis Arthritis - a variety of forms and complications .

For example, stem cells can be run in the laboratory to create a healthy heart muscle cells and transplanting them to patients with chronic heart disease Heart disease: prevention and prevention . The first study on mice and other animals have shown that transplantation of bone marrow stromal cells into damaged heart can yield positive results. What exactly do these cells - generate heart muscle cells, stimulate the formation of new blood vessels into the tissues of the heart, or through the help of any other mechanisms - are actively being investigated. For example, cells are introduced into the body can help restore, secreting growth factors, rather than directly forming new, healthy tissue of the heart muscle. The promising results of animal experiments formed the basis for the few studies involving people. Some recent studies have shown that is possible to direct the differentiation of embryonic stem cells or adult cells brainstem brain thus to obtain the cardiac muscle cells.

How safe stem cell therapy

On stem cell therapy in recent years, saying a lot. It is expected that in the near future, stem cell injections can treat cancer, heart disease Heart disease and heart attacks: that every woman should know   and other serious diseases. In addition, the stem cells can be used to reduce the signs of aging: with it the skin becomes more healthy and youthful, wrinkles are smoothed, other defects disappear.

There are several sources from which to obtain the stem cells, including - bone marrow and peripheral blood, which are typically taken from the patient, and - the umbilical cord.

Surprisingly, there are methods of cell therapy in which stem cells of animals used. Their supporters argue that the cells used are cleaned and completely safe for humans. The efficacy and safety of the use of such methods has not yet found scientific evidence.

Today we know that the most efficient and effective is the therapy using patient's own cells. Thousands of people worldwide have been certain kinds of cell therapy, in which stem cells to use them - complications are relatively rare and, in any case, no more than using the most traditional methods of treatment.

At the same time, experts warn patients that some clinics may be used stem cells derived from aborted human fetus from animals, as well as genetically modified cells. The use of these cells has not yet passed all the tests and inspections are necessary before a new treatment can be offered to people.

Cell therapy can be dangerous, and in the medical literature have been several cases where patients have died as a result of such treatment. When using animal cells in humans can develop viral or bacterial infections; Several cases of severe allergic reactions - some of them resulted in death. Possible complications such as swelling of the brain and the immune system to attack the blood vessels and nerves after cell therapy.

Pregnant women should not use cell therapy, since it is not known exactly how it affects the fetus.

Finally, it should be noted that there is no reliable evidence of successfully complete cell therapy using cells of animal origin. Relying on personal stories, in one form or another, doctors or patients, in this case it is not necessary; the scientific community, this method of treatment does not recognize, so for their own safety is best to avoid clinics that offer similar treatment.

How to choose the means to cleanse the skin

The choice of products for cleansing facial skin today is very wide, but choose among them a suitable remedy can be very difficult. Until relatively recently, women could only choose from several varieties of soap and cold creams, and now the shelves crowded with products designed for people with different needs, with the ingredients whose names seem quite unfamiliar.

What you need to clean the face

Cleansing the face is very important, because in the face is a lot of sebaceous glands that produce sebum continuously - naturally oil for moisturizing the skin. However, if the skin is too much sebum accumulates, it clogs pores, there are acne, skin tone does not change for the better. In addition, we use every day cosmetics, which forms a thin film on the skin which protects against such environmental contaminants such as dust, exhaust gas, cigarette smoke, and so on. Given all this, one can conclude that the skin needs to be aggressive cleansing.

What you need to gently clean the face

Before you start to scrape off the face of all the oil, dirt and makeup, you need to understand how delicate the skin on the face. The top layer of skin (stratum or layer) of layers of cells is less than in other parts of the body - except for the genitals. Because of this, the facial skin is most prone to irritation. In addition, since the person is very mobile and there are many nerve endings, taut skin is felt especially strongly. Because of this, the face skin is particularly sensitive, and it requires gentle cleansing.

How to clean your face

Perhaps the most important rule to cleanse the skin is: Use the mildest cleanser of those who are really effective in removing oil from your skin, make-up and pollution.

In no case do not wash your face with the same tool that you use for the body, even if you use a mild shower gel with moisturizing properties. If you wash ordinary soap, try to rethink their approach to cleanse the skin.

You can hardly go wrong if you select a non-foaming agent for skin cleansing wipes, or - they are perfectly removes dirt and soften the skin, leaving no feeling of tightness. Means abrasive particles should not use more than two or three times per week; for dry skin enough one times a week.

Tools for cleansing facial

Do you think enough of your usual cleaning agents, and it needs a thorough cleaning? If so, you are not alone. That need for a thorough, deep cleansing facial serve as a stimulus for the development of special tools that allow you to better clean the skin. But we should not forget that the cleansing of the skin with the help of such tools is similar to the use of scrubs - they can make the skin more dry and lead to the emergence of micro.

• Net cleansers

The first type of the sponges were made of polyester fibers are not interwoven, but are glued to each other. The adhesive does not soften even in the warm water, so these sponges were too harsh for the skin. Modern mesh scouring pads made of soft woven mesh; In addition, they come in different degrees of hardness, so that you can find a loofah, ideal for your skin type How to determine your skin type .

• Facial Tissues

Facial Tissue is one of the most popular types of funds to cleanse the skin. Some wipes impregnated with cleaning agents that are starting to foam when you rub the wet face cloth. In other contained cleansing lotions for different skin types.

• Brush for face

Brushes for the face are as usual with pile of different degree of hardness and electrical operating in different modes, and delivers deep, intensive cleaning. One of the newest electric brushes for the face - Clarisonic; it is produced by the same company as the electric toothbrush Toothbrushes - make no mistake in choosing   Sonicare (apparently they really like a big toothbrush).

Most women still enjoy conventional brushes - they are cheaper, but also give good results. The main thing - be careful: if you choose a brush with stiff bristles too, or will be too hard to rub the skin, it can cause irritation and redness.

What to choose

Most of these abrasive tools for cleansing the skin are netted sponge and a brush for the face. If you have very oily skin Oily skin: Natural and artificial care , Is to use them once every two or three days to remove the sebum and dead skin cells. If you have normal or dry skin Dry skin: care and treatment You are more suitable facial tissue.
