Stem Cells

  1. 1. STEM CELL
  2. 2. CONTENTS      Definition Properties Types of stem cell:1.Embryonic stem cell 2.Adult stem cell Application of stem cell Future of stem cell
  3. 3. DEFINITION  Stem cells of a particular tissue are defined as undifferentiated cells,are capable of proliferation & are able to self maintain the population .
  4. 4. GENERAL PROPERTIES 1.Capable of dividing & renewing themselves. 2.Unspecialized cells. 3.Give rise to specialized cells.
  5. 5. TYPES  1.Embryonic stem cell-  MULTIPOTENT : - cell can give rise to multiple cell type.  PLURIPOTENT : -able to give rise to derivatives of 3 germ layer.  TOTIPOTENT : -able to give rise to entire organism.  2.Adult stem cell-  UNIPOTENT : -can produce only one type
  6. 6. Microscopic view of colonies (rounded, dense masses of cells) of human embryonic stem cells in biologist James Thomson's research lab . Embryonic stem cells can be grown in culture dishes. A pinkish solution provides the sugars and other compounds the cells need to grow.
  7. 7. TYPES-(Base upon the source of the origin)  1.Haematopoietic stem cellsBone marrow  2.Mesenchymal/Marrow stromal cellsBone marrow , Culture into Osteoblasts  3.Neural stem cells- Neurons ,Astrocytes ,Oligodendrocytes
  8. 8. THERAPEUTIC APPLICATION OF STEM CELLS  Cell replacement therapy. - Myocardial infarction, Parkinson’s disease  Production of heart muscle cells. - Heart attack  Treatment of diabetes. - Type-1 Diabetes  Skin replacement therapy. - During injury  Tissue engineering application. - Injured organs like liver, kidney, eyes, heart & parts of the brain .
  9. 9. FUTURE PERSPECTIVES  Skin replacement therapy are need further exploration and extensive investigation, experimental confirmation and clinical trials.  Before they will be made available as an ideal cell substitute for the treatment of a number of degenerative disorder.  ES based cell replacement therapy will revolutionize medicine in the near future.
