1

cancer cell

cell that grows and divides in an unregulated way to produce a tumour

2

differentiation

changes to cells that allow them to specialise for different functions

3

diploid

refers to a cell having two matching sets of chromosomes

4

embryonic stem cells

stem cells from embryos that can divide and become any type of cell

5

ethical issue

issue affecting human attitudes and decisions regarding various choices

6

germline cell

cell that can give rise to gametes

7

haploid

describes a cell having one set of chromosomes

8

homologous chromosomes

matching chromosomes in a diploid cell; each member of a homologous pair has the same genes but may have different alleles

9

lymphocyte

type of white blood cell involved in a specific immune response

10

meiosis

type of cell division resulting in four haploid gametes

11

mitosis

division of the nucleus of somatic or germline cells, giving two diploid daughter cells

12

multipotent stem cell

stem cell that has the potential to make almost all cell types found within a particular tissue

13

phagocyte

white blood cell that can surround, engulf and digest foreign material and pathogens

14

pluripotent stem cell

stem cell that has the potential to make almost all cell types found within a particular tissue

15

red blood cell

blood cell containing haemoglobin, which can carry oxygen in the bloodstream

16

regulatory signal

molecular signal that can be received by a cell to modify its activity

17

secondary tumour

cancer formed from cells transported from a primary tumour

18

somatic cell

body cell that divides by mitosis to form more body cells

19

stem cell

unspecialised cell that can divide and then differentiate

20

therapeutic

used as part of a medical therapy

21

tissue stem cells

stem cells from tissue that divide and differentiate to become cells of that tissue

22

tumour

collection of cancer cells produced by excessive uncontrolled cell division
