What are the different types of regeneration?
sadasd
Define Regeneration?
dasdasd
Define Homeostatic regeneration?
dasdasd
Define injury induced or facultative regeneration?
asdasd
What cells can do the regeneration? Which types specifically?
wadsad
Define Homeostasis?
edasdasd
Define Facultative?
asdasd
What is facultative regeneration? What animals can do this?
dasdasd
Define regeneration? Define repair?
sadsadasd
What are the types of facultative regeneration?
dasdasd
What is epimorphosis?
sdasd
What is morphallaxis?
dasdasd
What is compensatory regeneration?
sdasdads
How does salamander limb regeneration occur? What type of regeneration is it?
sadasdad
What is the process of salamander limb regeneration? What is needed?
dasdasdasd
What are the nerves doing during this limb regeneration process? What is released?
wdsadasdasd
What happens if you denervate a limb stump? What happens if you add in nAG after denervating a limb after chopping it off?
sdadads
How does a blastema form? What does it form as a result of?
dsadasddasd
What happens after blastema formation?
dasdadsad
How does specification happen from the undifferentiated blastema? What genes are involved?
asdsdadsad
What type of cells can change into other cells after amputation during regeneration? Why?
dasdasd
How is positional memory maintained? What does this result in after amputation?
dadsasd
What is the retinoic acid gradient? What is a consequence of this?
dasdasdadads
What does retinoic acid expression control?
dasdadasewq
What levels of retinoic acid do the different blastema express? What does this result in?
dasdasd
What happens if a proximal blastema is removed and a distal blastema is grafted to proximal stump?
dasdadas
What is proximal-distal deletion?
DASDASDCZX
What happens is a proximal blastema is placed on a distal stump? Why?
sadasdad
What is proximal-distal duplication? What does it lead to in salamanders?
sadsasddas
Where is there intercalation? Where is there not intercalation?
dasdasd
How can the retinoic acid disrupt the proximal-distal axis?
sasadads
Why do you not give vitamin A to a pregnant lady?
sasdasdasdsad
How does intercalation happen in insects? How is it different to the salamander?
dasdasdadsad
If you add retinoic acid to a distal blastema what would happen?
dasdadas
What regeneration occurs in the Liver? Why?
dasdasd
How does “regeneration” happen in the liver?
dasdasd
What is morphallaxis? What is an example?
edasdasdad
What in humans potentially be an example of morphallaxis?
