stem cell is undifferentiated cell in our body which have the capability to produce organs or even whole organism. In this presentation we will discuss about the stem cell its definition, types and its application. The use of stem cell in different health insitution for the purpose of regeneration of organs through stem cell treatment.

3. Definition:
 Stem cell are the unspecialized biological cells that can divide and
differentiate into specialized cell type.
 Stem cell are found in Multicellular organisms.

4. Properties:
 They can self renewal/divide and produced more stem cell to maintain its
undifferentiated state.
 They can differentiate into other cells type.
 Stem cell are unspecialized but have the ability to specialized and the process
by which unspecialized cells is converted into specialized cells is called
differentiation.

5. Cell potency:
 Cell potency is the cell ability to differentiate into other cell type.
 A cell which can differentiate into more cell types greater it potency.
 Potency is also describe as the gene activation potential within the cell is
called cell potency.

6. Type of stem cell:

7. Toti-potent stem cells:
 These cells have the ability to produce complete fully functional / Viable
Organism.
 These cells can differentiate into embryo as well as Extra embryonic
tissue.E.g Aminon, Allantois, Yok sac and Chorion.
 Zygote is the example of totipotent stem cells.

8. Pluri-potent stem cells:
 Descent to totipotent stem cells they can differentiate into nearly all cells
type.
 Cells derived from any three germ layer.
1) Ectoderm.
2) Endoderm.
3) Mesoderm.
 The Embryonic stem cells are the best example of pluripotent stem cells.

9. Multi-potent stem cells:
 Multipotent stem cells are differentiate into specific range of cells type.
 The can differentiate into those cells type which are closely related family.
 An excellent example is Mesenchymal stem cells.
 Mesenchymal stem cells is derived from mesoderm layer and differentiate
into osteoblast (bone cell), myocytes ( muscle cells), adipocytes (fat cells)
and chondrocytes (cartilage cells).

10. Oligo-potent stem cells:
 These cells can differentiate into a very closely related cells type or few cells
type.
 The differentiation level of oligopotent is vey limited.
 Excellent example of this cells type is Hematopoietic stem cells.
 Hematopiotic Stem cells derived from mesoderm that can differentiated
into other blood cells like Myeloide and Lymphoid cells.
 Myeloid cell include basophil, esonophill, erythrocytes and macrophages.
 While lymphoid cell include B cells, T cells and natural killer cells.

11. Uni-potent stem cells:
 These cells differentiate into only one type of cells,its own cell.
 But these cells have the ability to self renewal which distinguish these cells
from non-stem cells.
 Example to this is Epidermis cell (produce only skin).

12. Trend:

13. Application:
 There are many application related to stem cells, some are as under;
 Latest research shows that blood can be form invitro from stem cells.
 Also stem cells can be use for organs reparing.
 Stem cells are use in plenty of treatments (Stem cell Therapy)
 Heart problem.
 Anti-cancer treatment.
 Alziemer’s treatment etc.
