Stem Cells and Differentiation

• What is the process of differentiation in cells?

  • Cells begin as a zygote (single cell).
  • The zygote divides by mitosis into multiple cells.
  • Cells become specialized to perform different roles.
  • This specialization is called differentiation.
• What is the significance of stem cells in differentiation?

  Stem cells are undifferentiated cells that can give rise to one or more types of differentiated cells.
• What are embryonic stem cells and their capabilities?

  Embryonic stem cells are found in the early stage of development of the embryo and can differentiate into any type of cell.
• Where are adult stem cells found and what is their function?

  Adult stem cells are found in specific tissues such as bone marrow, skin, and the lining of the intestine and lungs, and are responsible for replacing worn-out cells.
• What happens when one stem cell divides into two daughter cells?

  One daughter cell can maintain the properties of a stem cell while the other can differentiate into a new cell type.
• What are the advantages and disadvantages of using stem cells?

  Advantages:

  • Potential to treat various diseases.
  • Ability to regenerate damaged tissues.

  
  

  Disadvantages:

  • Ethical concerns regarding the source of stem cells.
  • Risk of tumor formation.
