What are differentiated cells?

Carry out certain functions

1

Unspecialized cells; not sure what they want to be

Stem cells

2

What does it mean to differentiate?

Become more specialized

3

What is the primary goal of stem cell research?

To grow different functioning cells. Understand what goes wrong when disease occurs

4

Formed as a normal part of embryonic development

Embryonic stem cells

5

What are the benefits of the embryonic stem cells?

Can be grown into any cell, source of treating diseases

6

What is controversial about the embryonic stem cell?

Cells are still alive

7

Exist naturally in the body

Somatic stem cells

8

What are the benefits of somatic stem cells?

Can be transplanted from patient to donor without drugs, can become a subset of related cell types

9

Where can you get somatic stem cells from?

Bone marrow, blood, brain, muscle, gut, heart, skin

10

What are the disadvantages of somatic cells?

Difficult to isolate and grow in culture

11

Created in lab by reprogramming a patient's cell

Induced pluripotent stem cells

12

What are induced pluripotent cells made from?

Skin and cells that produce connective tissue

13

What are the benefits of induced pluripotent cells?

Can become any cell in the body, can be a promising source of cells to treat diseases, no danger to immune system rejecting cell, less expensive

14

Directs the sequence of events that turn a blob of cells into any embryo with specialized tissues and organs

Gastrulation

15

How do cells in different parts of the embryo become different kinds of cells and organs?

Location, DNA

16

Have directions to make proteins when turned on

Genes

17

What kinds of proteins are found in different cells and organs?

Collagen, keratin, crystalin, actin, myosin, hemoglobin

18

Tells cells which kinds of proteins to make

DNA

19

What is he relationship between DNA, genes and proteins produced in cells?

DNA is wrapped around protein, DNA tells genes what to turn on and genes tell what proteins are needed to be made

20

How might a stem cell be used to treat a disease?

Scaffolding

21

What are embryonic stem cells referred to as because of their ability to become any cell they want?

Pluripotent

22

What are somatic cells referred to as because they are less flexible in their ability to become any cell they want?

Multipotent
