Cell Biology- Stem Cells Flashcards
Stem cells are _________________ cells found in _________, _____ animals and _________ in plants.
Stem cells are undifferentiated cells found in embryos, adult animals and meristems in plants.
Stem cells from human embryos can be ______ and made to ______________ into most different types of human cells.
Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells.
Treatment with stem cells can be used to help _________ and _________.
Treatment with stem cells can be used to help diabetes and paralysis.
Use of stem cells has risks, such as transfer of _____ _________ and religious and ethical
objections about killing a _________ _____ ____.
Use of stem cells has risks, such as transfer of viral infection and religious and ethical
objections about killing a potential human life.
describe the process of a bone marrow transplant due to leukemia
leukemia is a cancer of the bone marrow
the patients existing bone marrow is destroyed using radiation
the patient the receives a bone marrow transplant from a donor
the stem cells in the bone marrow then divide and from new bone marrow. the cells will also differentiate into different cells found in the blood such as red blood cells, white blood cells and platelets
what are the problems with bone marrow transplants
the donor and the patient have to be compatible otherwise the white blood cells made from the bone marrow might attack the patients body
viruses can also be spread
what is so important about meristem tissue
meristem tissue is a type of stem cell found in roots and buds. It can differentiate into any type of plant tissue at any point in the life of the plant
what can meristem tissue be used for
to clone a plant quickly and cheaply. `you might want to do this if the plant is becoming extinct or we could produce cloned crop plants for farmers
