Chapter 20 Vocab Flashcards
the production of embryonic stem cells for use in replacing or repairing damaged tissues or organs
therapeutic cloning
situated near the base or bottom of a structure
basal
cell junction with the inside portion of the cell attached to actin filaments
adherents junction
a gene whose normal function is to protect a cell form one step on the path doc cancer
tumor suppressor gene
half of a spot junction
hemidesmosome
network of protein and polysaccharides that cell secrete attach to
extracellular matrix
cells obtained form an embryo in the blastula phase which have only begun to differentiate and retain the ability to develop into any cell in the body
embryonic stem cell
making a full living copy of an organism; requires a surrogate mother
reproductive cloning
the ability of a cell and its descendants to retain the effects of past influences
cell memory
the transference of malignant or cancerous cells to other parts of the body
metastasis
a gene that causes that transformation of normal cells into cancerous tumor cells
oncogene
communication junction
gap junction
describes the tip or top of a cell structure
apical
cell to cell junction mediated by cadherin molecules
desmosome
groups of similar cells organized to carry out one of more specific functions
tissue
regions of connection between two cells or one cell with the extracellular matrix
cell junction
a glycoprotein in the extracellular matrix of animal cells that forms strong fibers in connective tissue and bone
collagen
cells in bone marrow that produce lymphocytes by mitotic division, for example
stem cell
junctions between the plasma membranes of adjacent cells in animals that form a barrier, preventing materials from passing between the cells
tight junction
a diseased caused by abnormal and uncontrolled cell division
cancer
what epithelial cells attach to
basal lamina
