Abstract

Background: This study was performed to investigate the rate of inner cell mass of BLASTOCYST which obtain from culture of mouse two cell embryos in presence and absence of recombinant of human leukemia inhibitory factor.Materials and Methods: ICR female mice that were between 6-8 weeks old received intra peritoneal injection of 7.5 IU of pregnant mare serum gonadotropine for super ovulation, this was followed by intra peritoneal administration of 7.5 of hCG 46-48 hours later. The mice were then mated to mature ICR male mice and were checked for vaginal plug 20 hours later. Female mice were killed by cervical dislocation 48-50 hours after hCG administration and after washing and flushing of the oviduct from the proximal end of the oviduct, two cell embryos were selected and collected by 100 microscopy. All two cell embryos were randomly divided in 4 groups (Groups A, B C and D) and culture in special media. Groups A: KSOM+AA, Groups B: KSOM+AA 500 IU/ml LIF. Groups C: KSOM+AA 1000 IU/ml LIF. Groups D: KSOM+AA 1500 IU/ml LIF media until 120 hours in Co2 incubator .After that time all BLASTOCYSTs collected and the number of ICM was assessed by differential staining technology. Results: The rates of ICM of BLASTOCYSTs which obtain from groups A, B, C and D were 19±2.6 28±4.4 ,24±2.1, 26±2.2 respectively. This data indicated that the rate of ICM in groups B, C and D was statistically higher than group A (P=0.02) and also there was not statistically different between three groups of B, C and D.Conclusion: Briefly LEUKEMIA INHIBITORY FACTOR can improve the rate of ICM of BLASTOCYST and we suggest that this factor is better added to BLASTOCYST culture medium.
