Sazetak:

Tissue remodelling during morphogenesis is usually triggered by biological
mechanisms, but it can be strongly affected by mechanical properties of the
developing tissue and its surroundings. Understanding tissue mechanics is
important part of morphogenesis description. During pupal stage of fruit fly
(\textit{Drosophila melanogaster}) development, wings are formed from
imaginal discs. We have observed wild type, perturbed and \textit{dumpy}
mutant wings from 16 to 32 hours after pupa formation. Specialized software
for cell tracking enables us to quantify contributions to tissue deformation
from different cellular processes. We developed a hydrodynamic theory which
accounts for observed tissue properties. Important contributions arising
from active cell behavior differentiate living tissues from 'passive'
non-living materials.
