3. DEFINITION

Stem cells of a particular
tissue are defined as undifferentiated cells,are
capable of proliferation &
are able to self maintain
the population .

4. GENERAL PROPERTIES
1.Capable of dividing &
renewing themselves.
2.Unspecialized cells.
3.Give rise to specialized cells.

5. TYPES

1.Embryonic stem cell-
 MULTIPOTENT :
- cell can give rise to multiple
cell type.
 PLURIPOTENT :
-able to give rise to derivatives
of 3 germ layer.
 TOTIPOTENT :
-able to give rise to entire
organism.

2.Adult stem cell-
 UNIPOTENT :
-can produce only one type

6. Microscopic view of colonies
(rounded, dense masses of
cells) of human embryonic stem
cells in biologist James
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.

7. 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

8. THERAPEUTIC APPLICATION OF
STEM CELLS

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 .

10. FUTURE PERSPECTIVES
 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
degenerative disorder.
 ES based cell replacement therapy will
revolutionize medicine in the near future.
