Table 2. Energy of bilayer skeletal separation at different gestational stages.

Maturational stage	W_sk (pJ/μm²)	SD (pJ/μm²)	n
E12.5	30.4	12.0	17
E14.5	49.1	22.4	17
E16.5	53.0	21.9	16

E = embryonic day.

The bilayer skeletal separation energy was determined by linear regression to the tether force squared as a function of the bilayer tension for individual cells. (See Equations 5–8, Fig. 5A.) The mean, standard deviation and number of cells measured are given for three different days of gestation.
