Comments p.114 left column bottom paragraph:"This [an effective spring constant of 5(1) N/m] directly corresponds to a Young’s modulus of the order of 10^5 Pa. Compared to other tissues, which have been studied experimentally [refs 7–9], this is rather large implying a more elastic behaviour of wing discs than of other tissues. It should be noted, however, that all of these investigations were done on embryonic tissues, which is not the case for wing imaginal discs. For instance, the mechanical fluctuations in the larva when feeding and moving are much higher than in the embryo, thus invoking stronger tissues. This is corroborated by moduli of adult tissues, such as blood vessels, skin or muscle, which range between 10^5 and 10^6 Pa [primary sources], comparable to [investigators’] results."
