Consisely, oocytes enucleation was performed under UV light, and a single fibroblast cell was injected into the perivitelline space of an enucleated oocyte in [M.sub.2] (Sigma, USA) medium supplemented with 10%FCS(HyClone, Beijing, China), 2 [micro]g/mL Hoechst 33342 (Sigma, USA) and 7.5 [micro]g/mL cytochalasin B (Sigma, USA).
Various shock applications including heat / cold shock, hydrostatic pressure and chemical agents (Colchicine, Cytochalasin B and [N.sub.2]O, etc.) have been used in the study in order to convert these haploid embryos, fertilized with spermatozoa and untreated, to diploid embryos [4,6-10].
The reconstructed embryos were equilibrated in PZM-3 supplemented with 5 mg/mL cytochalasin B for 2 h at 38.5degC in humidified atmosphere of 5% CO2, 5% O2, and 90% N2 (APM-30D, ASTEC, Japan).
24 h after seeding (G1/S exposure), cultures were treated with different concentrations of BWD-1 (3, 15, and 75 [micro]g/[cm.sub.2]) 20 h prior to cytochalasin B addition (Sigma, 6 [micro]g/ml) and the cultures were incubated for additional 28 hour (48 h treatment total).
Cytochalasin D (cyto D) is a cell-permeable actin depolymerizing agent that inhibits endocytosis, but extended exposure to cyto D is cytotoxic.
To validate the results obtained by in Vitro Microflow kit, the analysis of MN in binucleated cells was performed by adding cytochalasin B (Sigma-Aldrich; final concentration of 6 [micro]g/mL) after 44 h of culture [34].
