Types of stem cell:1.Embryonic stem cell
2.Adult stem cell
Application of stem cell
Future of stem cell
Stem cells of a particular
tissue are defined as undifferentiated cells,are
capable of proliferation &
are able to self maintain
the population .
1.Capable of dividing &
3.Give rise to specialized cells.
1.Embryonic stem cell-
- cell can give rise to multiple
-able to give rise to derivatives
of 3 germ layer.
-able to give rise to entire
2.Adult stem cell-
-can produce only one type

Thomson's research lab
Embryonic stem cells can be
grown in culture dishes. A
pinkish solution provides the
sugars and other compounds
the cells need to grow.
TYPES-(Base upon the source
of the origin)
1.Haematopoietic stem cellsBone marrow
2.Mesenchymal/Marrow stromal cellsBone marrow , Culture into Osteoblasts
3.Neural stem cells-
Neurons ,Astrocytes ,Oligodendrocytes
THERAPEUTIC APPLICATION OF
Cell replacement therapy.
- Myocardial infarction, Parkinson’s disease
Production of heart muscle cells.
- Heart attack
Treatment of diabetes.
- Type-1 Diabetes
Skin replacement therapy.
- During injury
Tissue engineering application.
- Injured organs like liver, kidney, eyes, heart & parts
of the brain .
Skin replacement therapy are need further
exploration and extensive investigation,
experimental confirmation and clinical trials.
Before they will be made available as an ideal cell
substitute for the treatment of a number of
ES based cell replacement therapy will
revolutionize medicine in the near future.
