Stem Cells Flashcards
difference between embryonic stem cells and adult stem cells
- embryonic can become all cell types of the body because they are pluripotent
- adult cells are limited to differentiating into different cell types of their tissue or origin
what are stem cells used for in the medical field
replacing or rejuvenating damaged tissue
what are the advantages of stem cell research
- provides medical benefits and insights of cloning and regeneration
- potential for treating diseases like Parkinson and cancer
- organs could be grown in labs for transplants.
what are the disadvantages of stem cell research
- unknown long term effects as its a new field
- patients body might reject embryos which causes more problems
- embryonic cells involve destruction of fertilised human egg cells (inhumane)
what could embryonic stem cells be specifically used for in the medical field
embryonic stem cells could be used to make more specialised tissues that have been lost to disease or injury, basically replace faulty cells
where are stem cells found in a plant and what is that part
- located in the meristems of plants
- the part of a plant where growth occurs
where are the stem cells found in the body
in the bone marrow, mainly, and the brain etc..
what can stem cells do
they can divide into more stem cells and become any cell in the body (differentiate)
what does a stem cell do when it becomes a specific cell for a specific function
it differentiates
what can be done to prevent a patient’s body from rejecting the stem cells
- have the stem cells go through therapeutic cloning
- where the embryo could be made to have the same genetic information as the patient
- meaning produced stem cells have the same genes as patient and wouldnt be rejected when replacing faulty cells
what are stem cells
stem cells are undifferentiated cells
how do humans use the stem cells of plants
- to produce clones of whole plants quickly and cheaply
- grow plants or rare species so they arent wiped out
- used to grow crops with desirable features for farmers, like disease resistance
what is the difference between plants and animals in the ways that they preserve their stem cells
plants will have stem cells throughout their lives where as the ability to differentiate is lost at an early stage for animals
what are cells that differentiate in mature animals mainly used for
repairing and replacing cells, such as skin and bone
what is differentiation
the process by which a cell changes to become specialised for its job
