Examination of the Contributions of Maternal/Placental-Derived Galectin-1 to Pregnancy Outcome

Galectin-1 (gal-1), a member of a family of evolutionarily conserved glycan-binding proteins, is differentially expressed at the feto-maternal interface and appears to be functionally polyvalent, with a wide range of biological activities. However, the contributions of maternal and/or feto-placental gal-1 to the signaling networks promoting a healthy pregnancy are still being elucidated. This chapter discusses the methods commonly employed to study the maternal or feto-placental contribution of gal-1 during pregnancy in mice. The methods described here can be used to decipher the specific role of each source, e.g., maternal and/or feto-placental derived gal-1 in the orchestration of pregnancy-associated processes.
