What are stem cells?
Unspecialized cells that develop into specialized cells
Who suggested the name 'stem cells' for the cells that can differentiate into another cell type?
Alexander Maksimov
In what year were the first embryonic stem cells (ES cells) independently derived from mouse embryos?
1981
Who were the two groups that independently derived the first embryonic stem cells (ES cells) from mouse embryos?
1- Martin Evans and Matthew Kaufman from the Department of Genetics, University of Cambridge 2- Gail R. Martin, University of California, San Francisco
Which American scientist discovered mesenchymal stem cells in 1991?
Arnold Kaplan
In what year were human embryonic stem cells first derived?
1998
What is the ability of medical signal cells revealed by Arnold Kaplan in the interview with Science?
The ability to help treat pain and protect body cells from death as a result of lack of Mesenchymal Stem Cells.
What are the general characters of stem cells?
1- Self renewing for long time: keeping stemness stage 2- Potency: Have the ability to differentiate into a wider range of adult cells 3- Plasticity: Can differentiate into another cell type other than its original tissue 4- Relocation: Can migrate from its original place to another place.
What are the classifications of stem cells based on potency?
Totipotent, Pluripotent, Multipotent, Oligopotent, Unipotent, or induced pluripotent.
Where do embryonic stem cells come from?
Embryos that are three to five days old, called a blastocyst and has about 150 cells.
Where are adult stem cells found?
Adult tissues, such as bone marrow or fat.
What are induced pluripotent stem cells?
Regular adult cells altered to have properties of embryonic stem cells through genetic reprogramming.
What are perinatal stem cells?
Stem cells discovered in amniotic fluid as well as umbilical cord blood, with the ability to change into specialized cells.
Which body fluids contain stem cells?
1- Synovial fluid 2- Amniotic fluid 3- Menstrual blood 4- Mother milk
What are the different classifications of stem cells based on their sources?
Embryonic or Adult
What is the basis for classifying stem cells by the extent to which they can differentiate into different cell types?
The extent to which they can differentiate into different cell types.
Test your knowledge about the characteristics and historical perspectives of stem cells, which are unspecialized cells that have the ability to develop into various specialized cell types. Learn about their renewal through mitotic cell division and their significance in the human body.
