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.
