To increase public understanding on cloned cattle derived from somatic cell nuclear transfer
(SCNT), the present review describes the effect of calf death loss on an SCNT cattle herd …

Background To investigate mechanisms of fetal-maternal cell interactions in the bovine
placenta, we developed a model of transgenic enhanced Green Fluorescent Protein (t …

Abstract Advances in Artificial Reproductive Technologies (ARTs) in bovine embryos to
produce cloned pregnancies have been developed in the last years, however high …

Cloning by somatic cell nuclear transfer (SCNT) is characterized by low efficiency and the
occurrence of developmental abnormalities, which are rather poorly studied phenomena in …

Abstract Changes in the nutritional plan have been shown to affect oocyte quality, crucial to
oocyte donors animals used in cloning. This study aimed to evaluate the impact of diets with …

Background Placental and fetal growth requires high rates of cellular turnover and
differentiation, which contributes to conceptus development. The trophoblast has unique …

The histomorphometric and proliferative characteristics of the collared peccary (Tayassu
tajacu) placenta and uterus were analyzed. The material was examined by standard …

The placenta of mammals is a structure formed by the juxtaposition of the fetal membranes
