TROPHOBLAST INVASION AND UTERIOIMPLANTATION GROWTH IN EARLY RAT GESTATION REQUISITE ADRENOMEDULLIN - Padma, Kanchi Ravi; Josthna, Penchalaneni (Asian Journal of Pharmaceutical and Clinical Research, 2018)
Â Objective: Adrenomedullin (ADM) is a currently exposed hypotensive peptide that is articulated in a variety of cell and tissue types. The existence of ADM has been immunohistochemically demonstrated in pathologic uterioimplantation regions, but no systematic study of ADM expression in early pregnancy in uterioimplantation region has been reported. Methods: Rats on the gestational day 2 were implanted subcutaneously with osmotic (Alzet) minipumps delivering 125 and 250 Î¼g rat/day/of AM22â€“52 and were killed on the gestational day 9. We have ascertained the hypothesis that ADM, a multiregulatory ubiquitous peptide hormone, works as a trophoblast pro-invasion factor. Results: We confirmed ADM significance in in vitro assay using ACH-3P cell line, which is first-trimester trophoblast cell line. Conclusion: Our data support the conception that ADM is involved in the human implantation process through regulating trophoblast proliferation and differentiation.
