Stem-cells-importance-in-human-body

Read this passage on Stem Cells and answer the questions below it:

stem cells importance to generating human body organism. such as heart, lungs, and leaver, not just that it helps in creating many organism.

Stem cells are one of the most fascinating areas of biology today. Research or stem cells have shown how an organism develops from a single cell. And how healthy cells replace damaged cells in adult organisms. 

Stem cells were used effectively in the treatment of many diseases. These Cell-based therapies are called regenerative or reparative medicine. 

What are stem cells?

Stem cells have two important characteristics that distinguish them from other types of cells. First of all, they are not specialized cells. They renew themselves for long periods through cell division.

Stem cells importance and introduction


The second is that under certain physiology or experimental conditions. They can induced to become cells with special functions.

Such as the beating cells of the heart muscle or the insulin-producing cells of the pancreas. 


Scientists primarily work with two kinds of stem cells from animals and humans. Embryonic stem cells and adult stem cells, which have different functions and characteristics. Scientists discovered ways to get or derive stem cells from early mouse embryos. this happened more than 20 years ago. 


Many years of detailed study of the biology of mouse stem cells. That led to the discovery, in 1998, of the process of isolating.

Stem cells from human embryos and growing the cells in the laboratory.  These are called human embryonic stem cells. 

What are stem cells


The embryos used in studies that is created to treat infertility. That happened through Vitro fertilization procedures. And when they no longer needed for that purpose. They donated for research with the informed consent of the donor. 


Stem cells are important for living organisms for many reasons.  In the 3- to 5-day-old embryo, called a blastocyst. Stem cells in developing tissues give rise to many specialized cell types. Those cells make up the heart, lung, skin, and other tissues. It’s an incredible development in the steam cells.


In some adult tissues, such as bone marrow, muscle, and brain. its also discrete populations of adult stem cells. These stem cells help to generate replacements for cells. And that are lost through normal wear and tear, injury, or disease.


Scientists believe that stem cells may, at some point in the future, become the basis for treating diseases. Such as Parkinson’s disease, diabetes, and heart disease, etc.


They want to study stem cells in the laboratory. So they can learn about their essential properties. And also they will Be able to analyze what makes them different from specialized cell types. 

Stem cells importance


As scientists learn more about stem cells. it may become possible to use the cells not just in cell-based therapies. it can be also be used for screening new drugs and toxins and understanding birth defects. 


To develop such treatments. Scientists are intensively studying the fundamental properties of stem cells, which include:

  • determining precisely how stem cells remain unspecialized and self-renewing for many years; and
  • identifying the signals that cause stem cells to become specialized cells.

Importance of steam cells

Stem cells are important for living organisms for many reasons. Within the 3- to 5-day-old embryo, called a blastocyst. The inner cells produce the whole body of the organism, including all of the various specialized cell types and organs like the guts, lung, skin, sperm, eggs, and other tissues.

In some adult tissues, like bone marrow, brain, and muscle. Discrete populations of adult stem cells try to generate replacements for cells.

That are lost through normal wear injury, disease, or tear. It shows the advancement and progress of stem cells and how they form somebody’s part.

Given their unique regenerative abilities, stem cells offer new potentials for treating diabetes like diseases and heart conditions. However, much work remains to be wiped out the laboratory.

Therefore the clinic to know the way to use these cells for cell-based therapies to treat disease. Which is additionally mentioned as regenerative or reparative medicine.

Laboratory studies of stem cells help all the scientists to find out more about the stem cells. Its essential properties and what makes them different from specialized cell types. Scientists are already using stem cells in the laboratory to develop model systems to review normal growth and identify the causes of birth defects. And also to screen the new drugs.

Research on stem cells continues to develop knowledge about how an organism develops from one cell and helped to form many body parts.

This way healthy cells replace damaged cells in adult organisms. somatic cell research is one among the foremost fascinating areas of up to date biology. But, like many expanding fields of scientific inquiry, research on stem cells raises scientific questions rapidly because it generates new discoveries.
