What are Stem cells??

The human body is composed of 60 trillion cells. Cells are the smallest structural and functional units that work to sustain life.
The origins of all cells in the human body come from one particular type of cell called stem cells.
Stem cells have excellent Self-replicating ability and have differentiation ability to various tissues according to the enviroment in which they are located.
Stem cells are undiffentiated biological cells that can differentiate into various tissues such as muscles and nerves.
The the world is interested in the use of stem cells as it has infinite possibilities in the fields of beauty and medicine.

Types of stem cell

There are two major types of stem cell: embryonic stem cells and adult stem cells.
Adult stem cells are primordial cells just before they are differentiated into human organ cells, and are divided into cord blood stem cells, bone marrow stem cells,
and adipose-derived mesenchymall stem cells. These cell types differ depending on the parts of the body they are located.
Audult stem cells are relatively easy to extract and are safer than embryonic stem cells which has risk of cell transformation.

Embryonic stem cell	Adult stem cell
Harvested from fertilized eggs	Harvested from body parts such as recapital blood, fat, and bone marrow
Differentiation function into all cells	Differentiation function into specific cells
Ethical controversy as it is taken from fertilized eggs	No ethical controversy
	Relatively safe

Stem cell culture process

• Donor eligibility
• Collection and inspection of test cell tissue
• Cell culture
• Management of culture facilities and enviroment
• Safety evaluation of human cell tissue culture fluid
