Where Do Stem Cells Come From?

You have probably heard about stem cells on the TV. You have probably wondered if it may help you or a person you know with a severe illness. You might question what stem cell Dallas is and where do they come from.  

The raw materials of our body are called stem cells. This is where all other cells with unique purposes are produced. Stem cells divide to create more cells under the right conditions in a laboratory or the body.  

The divided cells are called daughter cells. They either turn into differentiation (unique cells) with a more detailed purpose, such as bone cells, heart muscle cells, brain cells, or blood cells or become new stem cells (self-renewal). 

Where Do Stem Cells Come From? 

  • Perinatal Stem Cells 

Scientists have discovered stem cells in umbilical cord blood as well as amniotic fluid. In addition to that, these stem cells have the capability of changing into unique cells.  

For those who don’t know, the fluid that is found in the sac protecting and surrounding a growing fetus in the uterus is called amniotic fluid. Scientists have recognized stem cells in amniotic fluid samples acquired from pregnant women to examine for abnormalities. This is a process known as amniocentesis.  

To fully know their potential, more studies of amniotic fluid stem cells are required.  

  • Adult Stem Cells 

Adult stem cells are obtained in tiny numbers in almost every adult tissue. This includes fat or bone marrow. Adult stem cells have a more restricted capability in creating different body cells, unlike embryonic stem cells.  

Scientists believed adult stem cells can generate only the same forms of the cell until recently. For example, scientists believed that stem cells located in the bone marrow can create blood cells only.  

But, developing evidence recommends that adult stem cells might be able to generate different forms of cells. For example, bone marrow stem cells might be able to generate heart or bone muscle cells.  

This study has led to early-stage clinical tests to examine safety and effectiveness in people. For instance, adult stem cells are being examined as of now in individuals with heart or neurological illnesses.  

Adult cells were tested to have characteristics of embryonic stem cells. Researchers have altered successfully ordinary adult cells into stem cells with the use of genetic reprogramming. Scientists can reprogram the cells to act the same as embryonic stem cells by changing the genes in the adult cells.  

This new method might enable scientists to utilize reprogrammed cells rather than embryonic stem cells and stop the immune system rejection of the new stem cells. But, researchers do not yet know whether using modified adult cells will cause negative effects on people.  

  • Embryonic Stem Cells 

Embryonic stem cells come from fetuses that are 3 to 5 days old. A fetus is called a blastocyst at this stage. Typically, it has around 150 cells.  

These 150 cells are known as pluripotent stem cells. This means they can become any form of cell in the body or can divide into more stem cells.
