Fig. 4. Analysis of mRNA expression for Ltf, Pgr and Ccnd1 genes.
RT-PCR analysis of Ltf, Pgr and Ccnd1 genes in the uterus. Total RNA was extracted and analyzed by comparative RT-PCR (21). Ribosomal protein L7 (rpl7) was used as a constitutive gene. Amplified DNA bands were visualized by ethidium bromide staining.
