Differentiation and Stem Cells Flashcards
(15 cards)
Cellular differentiation depends on:
Gene expression
Once a cell becomes differentiated:
Only the genes for maintenance and he special function of the cell are switched on and the rest are switched off
Adult stem cells are found in:
Skin and red bone marrow
Tissue(adult) stem cells can only give rise to a:
Limited range of cell types closely related to the tissue in which they are found
All differentiated cells derived from stem cells are called:
Somatic cells
Somatic cells divide by:
Mitosis
To form more somatic cells
Somatic cells differentiate to form different body tissue types:
Epithelial
Connective
Muscle and Neve
Mutations in somatic cells are not:
Passed to offspring
Diploid cells have:
23 pairs of homologous chromosomes
Germline cells lead to the formation of:
Gametes
A germline cell is diploid and divides by:
Mitosis
Germline cells are able to undero a second type of division called:
Meiosis to form gamete cells
Mutations in germline cells are:
Passed onto offspring
Stem cell research provides info on:
How cell processes such as cell growth,
Differentiation
And gene regulation work
Cellular differentiation is the process by which:
An unspecialised cell becomes altered and adapted to perform a specialised function
