Stem Cells

A somatic cell contains _______________

• Half the number of chromosomes coming from one parent
• a complete set of chromosomes coming from both parents

Stem cells can be obtained from

• embryos
• some adult tissues
• umbilical cord blood
• all of the above

What does "pluripotent" mean?

• able to divide and make many different types of cells
• not able to divide
• can only divide and make one cell type 
• if it divides, it will make a cancerous tumor

What are iPS cells, and what do they mean to stem cell research?

• Induced purpose stem cells, mean embryo cells were made into adult-like cells
• Induced purpose stem cells, mean adult cells were reversed to baby cells
• Induced pluripotent stem cells, mean adult cells were made into embryo-like cells
• Induced pluripotent stem cells, mean cells were totipotent and are now pluripotent

What is the difference between embryonic stem cells and adult stem cells?

• Embryonic stem cells can differentiate into more cell types than adult stem cells
• Adult stem cells are pluripotent, just like embryonic stem cells
• Adult stem cells can differentiate into more cell types than embryonic stem cells
• Adult stem cells grow bigger than embryonic stem cells
