The document provides an overview of human cell types and the role of stem cells, which are unspecialised cells capable of differentiating into various specialised cells. It categorizes stem cells into embryonic, adult, and induced pluripotent stem cells, each with distinct characteristics and applications in medicine. Additionally, the document poses questions related to cell biology to encourage exploration and learning about stem cells and their significance.

- 2. Introduction • The humanbody is made up of many specialised cells that perform specific functions. • Specialised cells arise from the differentiation of unspecialised cells during embryological development.

Use the questions below to help you complete a KWL chart to show the following information: K what you know already W what you want to learn about stem cells during this unit L complete this at the end of the unit to summarise what you have learned Some questions to think about… •What is a cell? •What varieties of cell exist? •What is a tissue? Give some examples. •What is an organ? Give some examples. •What is a system? Give some examples. •What is a stem cell? •What are some different types of stem cells? •What is the purpose of stem cell research? •What are some ways that stem cells have been successfully used in medicine? •What are some of the issues in stem cell research? •What are some of the misconceptions that people have about stem cell research?
- 4. What are stemcells? Stem cells are unspecialised cells that have the ability to reproduce and differentiate into a diverse range of specialised cells.
- 5. Types of stemcells Embryonic Adult
- 6. Embryonic stem cells •Embryonic stem cells are derived from an embryo about 4–5 days old (bastocyst). • These cells have the ability to differentiate into all of the cell types that make up an organism.
- 7. Adult (tissue) stemcells • Adult or tissue stem cells are found in small numbers in the tissues and organs of adults and children, including the brain, bone marrow, skeletal muscle and skin. • These cells give rise to a much more limited range of cell types and will tend to develop into cell types that are closely related to the tissue in which they are found. • These cells replenish differentiated cells that need replaced in the tissues in which they are found.
- 8. Other types ofstem cells • Stem cells can also be taken from the umbilical cord of new babies. • Like adult stem cells, these cells can differentiate into a limited range of specialised cells.
- 9. Induced pluripotent stemcells Induced pluripotent stem cells are adult cells that have been genetically reprogrammed to an embryonic stem cell-like state.
- 10. Somatic cells Somatic cellsare the differentiated cells that form the different types of body tissue that exist.

- 14. Germline cells Germline cellsinclude the gametes and the cells that produce the gametes.
- 15. Division of germlinecells • Germline cells can divide by mitosis to produce more germline cells. • Gamete mother cells divide by meiosis to produce gametes.
