Kajian In vitro Aktivitas Sel-Sel Trofoblas Blastosis Mencit Aging dan Pengaruhnya terhadap Kegagalan Implantasi

Abstract

The objectives of this in vitro study were to investigate the hatching rate, the outgrowth diameter andthe activity of mitochondria Nicotiamide Adenin Dinucleotide Dyhidrogenage (NADH)-CoQ reductase ofblastocysts trophoblast cells from aging mice. Blastocysts of aging (age >12 months) and young productive(age 2 months) mice were collected from the cornua utery at day-4 of pregnancy and were cultured inmDMEM medium supplemented with 10% New Born Calf Serum (NBCS), 10% ITS, and 50 ?g/mlgentamicine, in 5% CO2 incubator at 37°C for 10 days. The blastocysts hatching rate and the trophoblastsmonolayer were examined for their diameter outgrowth and the NADH-CoQ reductase activity. The resultsshowed that the hatching rate, the trophoblast outgrowth diameter and the activity of NADH-CoQ reductaseof blastocysts collected from productive mice were significantly higher than those collected from the agingmice (P<0,05). It can be concluded that the impairment of blastocysts implantation especially, in agingmice were caused by the low activity of the NADH-CoQ reductase that play important role in energyproduction needed for the hatching and trophoblast outgrowth.
