Figure 3: Limb proportions are altered by immobilization of embryonic chicks at selected time-points during development.
From: Limb proportions show developmental plasticity in response to embryo movement
Mean ± SEM lengths of femur, tibiotarsus (TBT) and tarsometatarsus (TMT) in control (n = 5) and immobilized (n = 4) chicken embryos is unchanged by (a) immobilization between E10–14. (b) Mean length of the femur and TMT but not TBT is reduced by immobilization between E13–16. (c) The length of all elements is reduced by immobilization between E15–18 when analysed by Mann Whitney U-test. MRI monitoring of mean ± SEM limb growth daily in control (n = 6) and immobilised (n = 4) chickens: (d) femur, (e) TBT and (f) TMT. *Indicates P < 0.5 and **indicates P < 0.01.
