Stem cells: breakthrough technology in modern medicine

Have you ever heard about the French treatment of burns by technology change, stem cells or injected stem cells to beauty? This is the technology marks a breakthrough remarkable in modern medicine can help you change your life.

When you are injured or sick cell in the body will also be injured or dead. At that time, stem cells will start to repair the cell damage or replace the cells had died away. Leveraging this principle, scientists have and are studying developed many applications based on stem cell technology to constantly improve the quality of human health.

What are stem cells?

The body has countless cells that help sustain life as heart cells, brain cells or kidney cells… In that, the body also has a type of cell called stem cells.

A particular cell type

Every cell in the body is associated with a certain role, but stem cells are a particular cell type because it can become many different cell types in the body from a cell initially. Or, in other words, the different cell types in the body from skin cells, intestinal cells to cells… are created from stem cells.

Some types of stem cells have the ability to develop into any type of cell in the body but also the cell types is limited. Such as stem cells in bone marrow can become red blood cells and white blood cells and other components of blood. However, these cells could not become skin cells.

Properties of stem cells

A stem cell must meet two elements is the ability to self-renew and the potential change:

• Self-refresh (self-renewal): Is the ability to go throughout the reproductive cycle of the cells but still keep the status of no differentiation.

• The potential (potency): Is the ability to differentiate into the form specialized cells.

Based on the potential change of the stem cell can divide into the form:

– Stem cells, omnipotent (totipotent): Are cells not yet differentiated have ability to differentiate into all different cell types in the body from a cell initially. Whole cell capable of developing into the fetus or the complete body.

– Stem cells, omnipotent (pluripotent): Are cells not yet differentiated have ability to differentiate into all cells of the body are derived from three monocot embryo: the leaves in the leaves, the middle and the outer leaves. Other than cells, the cells, the multimeter can not develop into the fetus or the complete body that can only create the cell line, tissue certain.

– Pluripotent cells (multipotent): Are the cells that can differentiate into cells located in a system are intimately linked with each other. Such as the hematopoietic stem cells can become red blood cells, leukocytes, platelets, lymphocytes…

– Stem cells single-energy (unipotent): The cells have differentiated this can only produce cells of the same type, but they are still considered stem cells do have the ability to self-renew. In normal conditions, the stem cells mature in many systems has differentiated has simple features and only differentiate into a cell line. Such as platelets created platelet new cells oriented stream pink bridge of pink bridge new…

The meaning of stem cells

Research on this cell type can help to find explanations for some functional activities and problems that occur in the body. From there, the expert can bring to many solutions feasible for the treatment of some disease is still no cure.

Scientists hope in the coming future, stem cells will be used to replace cells in the body have been compromised due to disease or injury.

Types of stem cells

Based on the source isolation can be divided into 3 types of stem cells are: embryonic stem cells, stem cells mature and stem cells multimeter touch.

1. Embryonic cells

From the earliest stages of pregnancy after the sperm fertilizes with the egg cell, the embryo will form.

These cells are derived from embryos from 3 – 5 days old. At this stage the embryo is called a blastocyst and has about 150 cells. If you use a special enzyme to separate the cells of this block, it will be obtained the embryonic stem cells.

2. Mature cells

This cell type is found in most tissues of adults, such as bone marrow or fat. However, this cell may also appear in children, the fetus, or extraction from cord blood.

In the body, the key role of this cell type is to maintain and repair the hurt in those institutions where they are found.

Technology use of grown stem cells in research and therapy is not controversial such as the use of embryo cells do not require destroying embryos. However, in comparison with embryo cells, mature cells have a limited ability than in the creation of the different cells of the body.

3. Cells multimeter touch

Cells multimeter touch (iPS) is the type of stem cells multimeter was created from mature cells. These cells promises to create a breakthrough in the field of regenerative medicine. IPS cells have the ability to multiply indefinitely and can develop into all other cell types in the body such as nerve, heart, pancreas, liver…

The biggest advantage of this type of cell is it has almost all functions of embryonic stem cells, but not created from the embryo should be limited to the moral arguments. In addition, iPS cells made from the cell usually of the patient should be less prone to body rejection problem or happen when transplanting cells into patients.

The effect of stem cells

The effect of stem cells can regenerate the cellular damage under these conditions suitable. This is significant in saving lives or repair the cell damage due to illness or accident. Below are the achievements on the effect of stem cells has been applied research.

1. Stem cells tissue regeneration

Effect tissue regeneration cell is the most important application of stem cell technology. Such as if you need an organ we still have to wait for a donor and then undergo a transplant. However, many patients may suffer shortage of donation. Once there, you can, thanks to differentiated cells to re-create a number of vital organs in the body.

In the case of the patient with severe burns need to change the new skin, doctors will use stem cells to put on underneath the surface of the skin to create new skin cells.

2. Stem cell beauty

Many research results showed types of stem cells, the tooth pulp (taken from milk teeth of children under the age of 10) can be used effectively in beauty technology. Cells milk teeth can repair and replace the old cells damaged in the body as well as treat many skin problems.

Technology beauty by stem cells will help to improve the problems such as pigmentation, aging skin, enlarged pores, at the same time firming the facial skin through the effects:

  • Increase resistance of the skin
  • Improve acne, melasma, acne scarring, acne scars
  • Fade pigmentation, black spots, skin lightening
  • The regeneration of collagen and elastin in the skin lesions
  • Enhances firmness and elastic strong skin texture

3. Stem cell treatment

Stem cell technology was born with the hope of finding out the feasible measures treatment of many diseases and improve the quality of life.

• Blood diseases: The doctor can use blood-forming stem cells to treat diseases such as leukemia, sickle cell disease and the issue of reduced immunity to another. Hematopoietic cells appear in the blood and bone marrow can generate all types of blood cells, in which the red cells carry oxygen and white blood cells against disease.

• Parkinson’s disease: In Parkinson’s disease, the lesion of brain cells will lead to the moving muscles can not control. Scientists can use stem cells to replenish tissues brain hurt. This will create the brain cells specialized to prevent the muscles move without control.

• Cardiovascular disease: The scientists are also studying the development of heart cells healthy in the lab for transplantation into people with heart disease. The new cells this can repair heart damage by restoring the heart with healthy tissue.

• Diabetes: cases of people suffering from diabetes type 1 may receive pancreatic cells to replace the cells that produce insulin has been lost or destroyed. Therapy the only treatment at present is graft pancreatitis, but there is very little pancreas available for transplantation.

Stem cell storage

You can donate stem cells to help those who are suffering from a disease or stored for yourself to use in the future. Stem cells can come from the following sources:

• Bone marrow: To get stem cells this, you will be given general anesthesia from the hip bone or pelvis. The expert will then isolate the stem cells from the bone marrow to the storage or donation.

• Peripheral stem cells: You will receive a number of injections makes the bone marrow release stem cells into the blood. Next, blood is taken out of the body and go through a machine to separate stem cells.

• Cord blood: stem cells can be collected from the umbilical cord after birth without harm to the baby. You can donate cord blood or store it.

When storing stem cells, you can easily reach the stem cells necessary in the future, at the same time minimize the possibility of rejection cells.

Still no little controversy revolves around the use of stem cell technology and much research still needs to be conducted to determine the effect of this cell type. However, this is a great achievement medical worth to be noted about the ability to treat disease and beautiful. If you have a condition, stem cell application, chances your life will change to the new page!
