From: Expression of nodal signalling components in cycling human endometrium and in endometrial cancer
Representative products from PCR reactions to amplify Nodal, Lefty and Cripto in endometrial samples collected at all stages of the menstrual cycle (n = 4/stage). A band corresponding to 330 bp was detected for Nodal, 206 bp for Lefty, and 511 bp for Cripto. PCR for β-actin (500 bp) on the same samples was performed to assess RNA loading. Mens = menstrual phase, EP = early proliferative, LP = late proliferative, ES = early secretory, MS = mid secretory, LS = late secretory.
