Abstract :
The influence of phosphate and/or glucose on the development of mice preimplantation embryos was investigated. Approximately two hundreds female mice (Mus musculus albinus) CBR strain 2 month of age were used. The animal were superovuleted using PMSG and HCG and were bred naturally by adult males (3-4 month of age). The one cell stage of embryos were harvested and used for culture in modified media supplemented with 0,0 mmol/l, 0,5 mmol/l, 1,0 mmol/l, phosphate and 0,0 mmol/l, 2,5 mmol/,l 5.0 mmol/l, 7.5 mmol/l, glucose. he results showed that supplementation of 1,0 mmol/l, phosphate support preimplantation embryos dewelopment better than of 0,5 mmol/l, and 1.5 mmol/l, supplementation of 2.5 mmol/l, glucose indicated to overcome cell-block, but the requirement of glucose to be increasing as the development more beyond two cell stage interaction of phosphate and glucose at 1.0 mmol/l, and 2.5 mmol/l, respectively support preimplantation mice embryos development. In conclusion, phosphate supplementation did not inhibited the development of embryos and cell-block can be overcome by lower concentrate of glucose the combination of phosphate and glucose serve a better environment for embryos development.
