چکیده مقاله:
Background: Matrigel (extracellular matrix) can improve the growth of many cell types in vitro. Objective: The aim of the present study was to determine the effect of Matrigel on thedevelopment of 2-4 cells human embryos in culture. Material and Methods: Surplus 2-4 cells human embryos, resulting from ICSI, weredivided into two groups (control and test). Quality of embryos in both groups was morphologically similar. The test group (n=140) was cultured in Hams’ F10supplemented with 10% human serum albumin and 150 μl liquid Matrigel. The control group (n=140) was cultured in the same medium devoid of Matrigel. Embryos werecultured for an additional 4 days and their morphology was assessed every 24 hours. Both groups were then statistically compared. Results: The percentage of the human embryos that reached the morula stage in thecontrol and test groups were 79.2% and 80%, respectively (p>0.05). However, 36.4% of embryos reached the blastocyst stage in the test group as compared to 5.7% in thecontrol group after 144 hours in culture. This difference was statically significant (p <0.01). In addition, culture of embryos on Matrigel and medium versus medium alonesignificantly improved in vitro hatching (25.7% versus 3.5%; p <0.01). Conclusion: Matrigel at low concentration enhances human blastocyst formation and hatching in vitro.
