  1. 1. What Are Stem Cells By StemCellMalaysia.com
  2. 2. Stem Cells DefinitionStem cells can be defined simplyas cells which are not specializedin any specific tissue or organs.In other words, stem cells havenot differentiated into other celltypes to form tissues and organs.They are the base or foundational cells to develop into cellswhich specialized in certain functions.Another distinguishing characteristics of stem cells is theirability to undergo division, giving rise to more stem cells.

  3. 3. Stem Cells Definition This is known scientifically as the ability to self-regenerate. The way stem cells self- regenerate is to divide and produce two stem cells with the exact characteristics.This is what happens initially.As they undergo further self-regeneration, they soon produceone stem cell and one cell which has more differentiation orspecialization. StemCellMalaysia.com
  4. 4. Stem Cells DefinitionThe significance of stem cells intheir application to the humanbody and human health boilsdown to the two importantcharacteristics of differentiationand self-regeneration.Imagine how powerful they can be if stems cells can bedeveloped into heart cells, especially when someone’s heartis doomed to fail. StemCellMalaysia.com
  5. 5. Stem Cells Definition Or, for someone with damaged brain cells or nerve cells, wouldn’t it be extremely great news if stem cells can develop new brain cells or nerve cells for the person.Indeed, the potential and possibilities of exploiting stem cellsfor medical science and health science are enormous.Many untreatable diseases and ailments may in the nearfuture become curable.

  6. 6. Types of Stem CellsStem cells are classified intovarious types based on theirability to undergo differentiationinto different cell types.In other words, their classification, and hence their name, isderived from their potential to develop into one, two orseveral other cell types. StemCellMalaysia.com
  7. 7. Types of Stem Cells For example, oligopotent stem cells can divide and produce 5 types of blood cells, including monocytes and macrophages.Totipotent stem cells have the ability to differentiatethemselves into all cell types.Pleuripotent stem cell is able to develop into all cell types,except cells of the embryonic membranes. StemCellMalaysia.com
  8. 8. Types of Stem CellsScientists have identified thevarious stem cells so thattargeted research can beperformed to discover specificapplications to the human healthand disease treatments.Understanding the specific types of stem cells will helpapplying the right type of stem cells to the appropriatecondition or illness. StemCellMalaysia.com
  9. 9. Stem Cells In Human Development The best way to understand stem cells is probably by looking at ourselves. You and I are formed from stem cells.The first stem cell that appears before a fetus develops isknown as zygote.When a sperm cell penetrates an egg cell from the mother, azygote is formed which contains all the genetic informationrequired to develop a human being. StemCellMalaysia.com
  10. 10. Stem Cells In Human DevelopmentIn a way, the zygote is thesuperior stem cell, having theability to divide and develop intoall cell types.From the zygote, a who;e pool or mass of different stem cellsare formed, providing the fetus the necessary stem cells todevelop various parts of the human body. StemCellMalaysia.com
  11. 11. Stem Cells In Human Development Once we understand how the master stem cell, the zygote, enables the development of a human being, it is not too difficult to imagine the potential to exploit stem cells for the regeneration of damaged organs or tissues in an adult.The question lies in whether we can exploit the ability ofstem cell for whatever treatment objectives we wish toaccomplish.
