Survival and viability of fresh and frozen-thawed in vitro bovine blastocysts.
Three experiments were undertaken to investigate the effect of some factors on survival and viability of bovine blastocysts produced in vitro in serum-free oviduct-conditioned media. In vitro survival to freezing was higher for blastocysts appearing on days 6 and 7 than for day 8 blastocysts (67 and 50% hatching rate vs 12%). Transfer success of day 8 blastocysts to recipient heifers was 35% (9...

متن کاملO-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
متن کاملThe Effects of Plla Nanofiber Scaffold on Proliferation of Frozen-Thawed Neonate Mouse Spermatogonial Stem Cells
Purpose: To investigate of the effects of a poly L-lactic acid (PLLA) nanofiber scaffold on proliferation of frozen-thawed neonate mouse spermatogonial stem cells.Materials and Methods: Spermatogonial cells were isolated from neonatal 3-6-day-old NMRI mice testes by two steps enzymatic digestion and differential plating. The isolated spermatogonial cells were divided into four culture groups: 1...
متن کاملHeat shock decreases the embryonic quality of frozen-thawed bovine blastocysts produced in vitro
In this study, the effect of heat shock on frozen-thawed blastocysts was evaluated using in vitro-produced (IVP) bovine embryos. In experiment 1, the effects of 6 h of heat shock at 41.0 C on fresh blastocysts were evaluated. HSPA1A expression as a reflection of stress was increased by heat shock (P < 0.05), but the expressions of the quality markers IFNT and POU5F1 were not affected. In experi...
