- Purpose: Crotamine is capable of penetrating cells and embryos and transfecting cells with exogenous DNA. However, no studies are available regarding its uptake by parthenogenetic (PA) embryos or its use for transfection in in vitro fertilized (IVF) embryos. This study aimed to determine the translocation kinetics of crotamine into PA and IVF bovine embryos and assess its effect over in vitro development of PA embryos. Moreover, crotamine-DNA complexes were used to test the transfection ability of crotamine in bovine IVF zygotes. Methods: PA and IVF embryos were exposed to labeled crotamine for four interval times. Embryo toxicity was assayed over PA embryos after 24 h of exposure to crotamine. Additionally, IVF embryos were exposed to or injected with a complex formed by crotamine and pCX-EGFP plasmid. Results: Confocal images revealed that crotamine was uptaken by PA and IVF embryos as soon as 1 h after exposure. Crotamine exposure did not affect two to eight cells and blastocyst rates or blastocyst cell number (p > 0.05) of PA embryos. Regarding transfection, exposure or injection into the perivitelline space with crotamine-DNA complex did not result in transgene-expressing embryos. Nevertheless, intracytoplasmic injection of plasmid alone showed higher expression rates than did injection with crotamine-DNA complex at days 4 and 7 (p < 0.05). Conclusions: Crotamine is able to translocate through zona pellucida (ZP) of PA and IVF embryos within 1 h of exposure without impairing in vitro development. However, the use of crotamine does not improve exogenous DNA expression in cattle embryos, probably due to the tight complexation of DNA with crotamine.
