Two references were omitted from the seventh sentence under the subheading “Histology” in the Methods section.

The sentence should read: For collagen staining, 10μm tissue sections were stained with picrosirius red (Polysciences Inc, Warrington, PA) as previously described (Junqueira et al., 1980; Yu et al., 1995).

The references are:

One reference was omitted from the tenth sentence under the subheading “Histology” in the Methods section.

The sentence should read: Specifically, after photomicrographs were converted to gray scale, they were inverted and OD was calculated using a calibrated threshold and the Rodbard standard curve (NIH Image J software) as previously described (Kirby et al., 2005).

The reference is: Kirby LS, Kirby MA, Warren JW, Tran LT, Yellon SM. Increased Innervation and Ripening of the Prepartum Murine Cervix. Journal of the Society for Gynecologic Investigation. 2005;12(8):578–85.
