The aim of the course is to elucidate the principles of the cell differentiation in the ontogenesis of the animal organisms. The main topics are genome stability and variability during embryogenesis, gene activity from the genetic and epigenetic point of view, processing and regulation of gene expression, inter-cellular relationships, propagation of inter-cellular signals, role of the extracellular matrix. Inductive interaction, morphogenetic field and positional information, hierarchy of genetic activities in morphogenesis, in the formation of the spatial orientation of animal body.

Morphogenesis and spatial orientation in amphibians. Inductive interaction as a principle of morphogenetic regulation. Mesodermal, neural, and other inductions. Experimental evidence of inductions and their molecular basis. Mechanisms of anterior-posterior (A-P) and dorso-ventral (D-V) axis symmetry in Xenopus model.

 

6. Body axis symmetry II

 

Body axis symmetry in fish, birds, and mammals. EVO-DEVO comparison of the A-P and D-V axis origin.

 

7. Body axis symmetry III

 

A-P and D-V axis symmetry in Drosophila melanogaster. Left-right symmetry in animals.

 

8. Regeneration and aging
