Following statements regarding to feedback loops during limb development.

A. When the limb bud is relatively small, an initial positive feedback loop is established between Fgf10 produced in the mesoderm and Fgf8 produced in the ectoderm, promoting limb outgrowth.

B. As the limb bud grows, the ZPA is established, and another regulatory loop is created by inhibiting the BMP in mesoderm and maintain FGF expression.

C. In anterior region of the limb bud, Fgf8 positively regulates Etv4/5, which in turn repress Shh in this region, further reinforcing the posterior-to-anterior gradient of Shh from the ZPA.

D. In posterior region of the limb bud, Fgf8 positively regulates Etv4/5, which in turn repress Shh in this region, further reinforcing the posterior-to-anterior gradient of Shh from the ZPA.

Identify the correct match of the modes of regeneration (column I) with their definition (column II)

Column I

Column II

A. Stem cell-mediated regeneration

i. Through the re-patterning of existing tissues. There is often little new growth but rather cell death and a change in cell type (i.e., transdifferentiation into a different cell fate). This results in a rescaling of the whole organism as well as regeneration of the missing part.

B. Epimorphosis

ii. The differentiated cells divide but maintain their differentiated functions. The new cells do not come from stem cells, nor do they come from the dedifferentiation of adult cells.

C. Morphallaxis

iii. Adult structures can undergo dedifferentiation to form a relatively undifferentiated mass of cells (a blastema) that then redifferentiates during morphogenesis of the new

structure.

D. Compensatory regeneration

iv. Stem cells allow an organism to regrow certain organs or tissues that have been lost.
