The Use of Stem Cells in Treating Human Disorders
The Use of Stem Cells in Treating Human Disorders
- Totipotent cells can produce any type of body cell and are found in early mammalian embryos.
- These cells only translate part of their DNA, leading to cell specialisation and only occurring for a limited time.
- Pluripotent, multipotent and unipotent cells are found in mature mammals; each type can divide to form different numbers of various cell types.
- Pluripotent cells can divide in unlimited numbers and are used in treating human disorders.
- Unipotent cells can develop into one type, as seen in the formation of cardiomyocytes.
- Induced pluripotent stem cells can be produced from adult cells using protein transcription factors.
- Students should be able to evaluate stem cell use in treating disorders, comparing stem cell types, uses, locations, benefits, and limitations.
- Students should consider the ethics of using each stem cell type.
- The use of a mind map to revise each type of stem cell is recommended.
