There are two types of stem cells: embryonic stem cells and adult stem cells
While embryonic stem cells are not free from the stability and ethical issues, adult stem cells pose no ethical problem because they can be collected from fat, placenta, marrow or cord blood. In particular, adipose stem cells derived from adipose tissues and placental stem cells that exist in placenta at the time of birth are safe, and have superior differentiation capability. They can be applied to treating various incurable diseases caused by cell damage: diabetes, Alzheimer’s disease, degenerative arthritis, cardiac infraction, cerebral infraction and renal failure.
Embryonic stem cell | Ault stem cell | |
---|---|---|
Characteristics | All-powerful cell generated in a fertilized egg at the blastocyst | Can be found in body tissues and organs |
Advantages | Powerful proliferation, easy self-production | No immunological rejection, easy medicinal application, no ethical problem |
Disadvantages | May form cancer, immunological rejection, poses ethical problem | Limitation of stem cell proliferation, easily loses the characteristics of stem cells |
Type | Characteristics |
---|---|
Cord Blood | Hematopoietic stem cell, capable of treating blood diseases, can be collected only at birth |
Placenta | Easily collected from placenta, can be collected only at birth |
Fat | Easily collected from fat, can be collected from patients in most age groups, provides a large number of stem cells, demonstrates superior cultivation and differentiation capability No immunological rejection |
Marrow | Difficult to collect from marrows, difficult to acquire and culture the required amount of stem cells, long history of use |
