Blastema cells surrounded by transparent
cystic spaces.
A 'blastema' is a mass of undifferentiated
cells capable of growth and
regeneration into
organs or body parts. Blastemata are typically found in the early stages of an
organism's
development such as in
embryos, and in the regeneration of
tissues, organs and
bone.
"Primitive" Organisms such as
salamanders can still produce blastema when adult; more developed organisms such as frogs can't. That's the reason why salamanders can
regenerate an amputed leg and frogs aren't able to do so.
