The influence of donated gametes on the incidence of hypertensive disorders of pregnancy.
Pregnancies achieved from oocyte, sperm or embryo donation are unique, since they have resulted from donor gametes that are immunologically foreign to the mother. Thus, studying the obstetric outcome of such pregnancies may shed some light on the pathophysiology of preeclampsia, particularly in women conceiving with donated embryos, since the entire fetal genome is allogenic in these pregnancie...
متن کاملThe beginning of a seed: regulatory mechanisms of double fertilization
THE LAUNCH OF SEED DEVELOPMENT IN FLOWERING PLANTS (ANGIOSPERMS) IS INITIATED BY THE PROCESS OF DOUBLE FERTILIZATION: two male gametes (sperm cells) fuse with two female gametes (egg and central cell) to form the precursor cells of the two major seed components, the embryo and endosperm, respectively. The immobile sperm cells are delivered by the pollen tube toward the ovule harboring the femal...
متن کاملFemale Control of Male Gamete Delivery during Fertilization in Arabidopsis thaliana
Fertilization in both animals and plants relies on the correct targeting of the male gametes to the female gametes. In flowering plants, the pollen tube carries two male gametes through the maternal reproductive tissues to the embryo sac, which contains two female gametes. The pollen tube then releases its two male gametes into a specialized receptor cell of the embryo sac, the synergid cell. T...
متن کاملSingle pair mating indicates maternal effects on embryo survival in rainbow trout, Oncorhynchus mykiss
The maternal and paternal influences on early embryo survival in rainbow trout are not established. The purpose of this study was to determine whether variability in the survival of rainbow trout embryos could be attributed to either the female or male parent. Gametes from individual female and male rainbow trout were used in single pair matings to produce families Ž whose survival was followed...
متن کاملEstablishing the epigenetic status of the Prader-Willi/Angelman imprinting center in the gametes and embryo.
The Prader-Willi/Angelman imprinted domain on human chromosome 15q11-q13 is regulated by an imprinting control center (IC) composed of a sequence around the SNRPN promoter (PWS-SRO) and a sequence located 35 kb upstream (AS-SRO). We have previously hypothesized that the primary imprint is established on AS-SRO, which then confers imprinting on PWS-SRO. Here we examine this hypothesis using a tr...
