HintAnswer
regrowth of amputated body parts of nonfunctioning organs
regeneration requires the _______ of the tissue
replacement of singular tissue type
4 Mechanisms of regeneration
repatterning of existing tissue with little new growth
dedifferentiation of adult tissues that forms an undifferentiated cell mass that ultimately becomes respecified
differentiated cells divide while maintaining their differentiated functions
tissue-specific adult stem cells serve as source of cells for regrowth
head generator
tail/foot generator
adult muscle stem cells
Is cell division required in morphallactic regeneration?
direct specific regeneration
This gene is a hypostome/apical hydra morphogen
This gene is a basal/foot hydra morphogen
best studied example of epimorphosis
True or false: all of the different cell types are present in the new limb formed by epimorphosis?
Regeneration in amphibians involves formation of a _____ by epimorphosis
ability to regenerate by epimorphosis is dependent on cells retaining ability to
proliferation of epidermal cells adjacent to stump will lead to
these degenerate at the site of amputation
these cells migrate under the AEC to form the regeneration blastema
transcription decreases in these differentiation genes during epimorphosis
transcription increases in these mesenchyme proliferating genes during epimorphosis
these cells redifferentiate to form the new structures of the limb
HintAnswer

in mammals there appears to be a neonatal ______ for regenerative potential
lizards can regenerate
lizard vertebrae have _____ break points
True or false: Regenerated tail inside is structurally identical to original tail
data suggests lizards regenerate by this mechanism
