Staining of cartilage in TBBPA, BPA, or TBBPA DME exposed embryos. Embryos were exposed in TBBPA (0.75 µM), BPA (10, and 15 µM), TBBPA DME (5 and 10 µM) or vehicle (DMSO) for 7 days, when they were euthanized and stained accordingly. Intraocular distance (ID), lower jaw length (LJL) and certohyal cartilage length (CCL) were measured. A representative photograph is shown depicting the location of each measurement. Error bars represent standard deviation and the asterisk denotes significance relative to control with a p ≤ 0.05.
