Flashcards in Module 7 - Developmental Biology Deck (14):
1

Hemorrhagic vs Ischemmic stroke

Hemorrhagic
- due to burst blood vessel
- acts like a bruise
- causes inflammation and death of cells

Ischemmic
- due to blood clot
- wide spread death of cells, the worse type of stroke

2

What do myeloid stem cells produce?

Granulocytes, erythrocytes and platletes

3

What do lymphoid stem cells produce?

T cells and B cells

4

What is a totipotent stem cell? Example

Stems cells that have unlimited capability to give rise to any cell within or outside of the body
e.g. embryonic stem cell

5

What is a phuripotent stem cell? Example

Stem cells that can give rise to any cell within the body
e.g. inner mass cells

6

What is a multipotent stem cell? Example

Stem cells that can give rise to cells that have specific function
e.g. blood stem cells

7

What is blastocyst?

early embryo (8 day) consisting of inner cell mass and trophectoderm

8

What are embryonic stem cells?

Stem cells that proliferate indefinitely and has the potential to differentiate into any kind of cell

A totipotent stem cell

9

What is a somatic stem cells? What are some other names for such cells?

A stem cells that gives rise to limited cell types

Multipotent stem cells

Adult, body or mature stem cells

10

What is the trophectoderm?

the layer of cells around the inner cell mass of a blastocyst

11

How can you make stem cells without using an embryo?

Somatic cell nuclear transfer

12

What is a fibroblast?

Purified cells developed from sample such as skin scrape

13

What is an oocyte?

an unfertilised egg without a nucleus

14

How does SCNT work?

the nucleus gets tricked by egg so it replicates and acts like a fertilised egg and a blastocyst containing the DNA of the fibroblast is produced
