• Totipotent stem <strong>cells</strong> <strong>are</strong> the most powerful stem cell<br />
• They can differentiate into embryonic <strong>cells</strong> <strong>and</strong> tissues<br />
• Have the ability to develop into a living organism<br />
• e.g. fertilized egg<br />
2. Pluripotent<br />
• These stem <strong>cells</strong> <strong>are</strong> having the ability to renew itself<br />
• They can differentiate into 3 germ layers – ectoderm, endoderm <strong>and</strong> mesoderm<br />
• Also, can develop into any kind of tissues or organs<br />
• e.g. embryonic stem <strong>cells</strong><br />
3. Multipotent<br />
• Multipotent stem <strong>cells</strong> possess the ability of self-renewing<br />
• They can different into a specific kind of cell<br />
• e.g. mesenchymal stem <strong>cells</strong><br />
4. Oligopotent<br />
• Oligopotent stem <strong>cells</strong> have the self-renewing capability<br />
• Restricted to differentiate into closely related cell types<br />
• e.g. hematopoietic stem cell
