Stem Cells

What is the source of human totipotent stem cells?

early stages of embryonic development fertilized egg

What is the unique ability of totipotent stem cells?

they are developed into the human body

Which human cell types can be produced using totipotent, pluripotent, multipotent, or iPSC stem cells?

Any cell types

What are the sources of each type of stem cell?

Pluripotent - inner cell mass of blastocyst - stage embryo

iPSCs - adult somatic cells (skin cells, blood cells, or urine cells)

What are medical uses of iPSCs?

What type of stem cells would you use to develop a therapy that could replace any of the 220 cell type in the human body?

Pluripotent

Why are pluripotent stem cells in the umbilical cord blood of infants collected at birth and stored?

can be used to treat various diseases (blood disorders, immune deficencies, and some cancers)

What are some medical advantages of cord blood banking?

preserved for future treatment

What are some functions of adult stem cells in the human body?

growth, immunity, renewal, repair

where are adult stem cells located in your body?

areas prone to injury and renewal sites

Why are adult stem cells located in body areas of growth or injury?

ready to divide and replace cells lost through normal wear and tear

How could adult stem cell therapy improve the quality of life?

replacement to medicanes from cells lost through cancer, disorders, infections, injury

What are some potential adult stem cell therapies?

Anti-aging, cancer, liver, kidney

Why is stem cell injection into the body a medical risk?

triggers immune response to attack the stem cells or stem cells might fail

What are Organoids

artifically grown mass of cells or tissues that resembles an organ

What are some uses for organoids?

personalized medicine, disease studying, regenerative medicine

Which stem cells are used to make organoids?

Pluripotent stem cells

Stem cells are defined by their—

Ability to reproduce (divide) in a highly controlled manner

Which type of stem cell has the remarkable ability to develop into the human body?
