Tetraploidy Induced by Electrofusion - A Review
| In vitro tetraploid embryo production has turn into an inestimable means in various research studies for researchers since last few years. The natural tetraploidy stage in embryo is exceptionally reported; hence different techniques have been engaged to bring the tetraploidy experimentally in mammals. There are three fundamental techniques to induce tetraploidy in vitro. First technique is th...
متن کاملOryzalin-induced Tetraploidy in Cryptomeria japonica (Cupressaceae)
Japanese-cedar [Cryptomeria japonica (L.f.) D. Don] represents an alternative to leyland cypress [·Cuprocyparis leylandii (A.B. Jacks. & Dallim.) Farjon] as an evergreen screen or specimen plant for landscapes. It performs well under a range of soil and environmental conditions but has been underused attributable, in part, to unsightly winter browning caused by photoinhibition. In previous stud...
متن کاملTetraploidy in a liveborn infant.
We report a 3 month old boy with tetraploidy, found in peripheral blood and skin fibroblast cultures, with severely delayed growth and neurodevelopment, and with a cleft lip; these findings have not been described before. This report brings to seven the total number of liveborn infants with a 92,XXYY karyotype.
متن کاملTetraploidy in hydatidiform moles.
STUDY QUESTION How does tetraploidy develop in hydatidiform moles (HMs), and what is the frequency of the different origins? SUMMARY ANSWER Most molar pregnancies with tetraploid cells appear to be produced by somatic endoreduplications, while a minority originate from a tetraploid zygote. The frequency of zygotic tetraploidy was estimated to be 0.7%. WHAT IS KNOWN ALREADY The parental orig...
متن کاملSomatic tetraploidy in specific chick retinal ganglion cells induced by nerve growth factor.
A subset of neurons in the normal vertebrate nervous system contains double the normal amount of DNA in their nuclei. These neurons are all thought to derive from aberrant mitoses in neuronal precursor cells. Here we show that endogenous NGF induces DNA replication in a subpopulation of differentiating chick retinal ganglion cells that express both the neurotrophin receptor p75 and the E2F1 tra...
