The effects of sugars and growth regulators on embryo- and callusogenesis in isolated ovules culture of beetroot, Beta vulgaris L. [PDF]
Haploid techniques have risen interest among researchers and breeders as they significantly reduce the time of creating pure lines in breeding programs, especially for biennial vegetable crops.

Regulatory principles governing the maternal-to-zygotic transition: insights from Drosophila melanogaster [PDF]
The onset of metazoan development requires that two terminally differentiated germ cells, a sperm and an oocyte, become reprogrammed to the totipotent embryo, which can subsequently give rise to all the cell types of the adult organism.

Background: Parasitic conjoined twin is a rare but well-known entity with unclear embryopathogenesis. Abnormal conjoined twinning can result in an externally attached parasitic twin (PT), an enclosed foetus in foetu, or a mature teratoma.

A mathematical modelling portrait of Wnt signalling in early vertebrate embryogenesis [PDF]
There are two phases of Wnt signalling in early vertebrate embryogenesis: very early, maternal Wnt signalling promotes dorsal development, and slightly later, zygotic Wnt signalling promotes ventral and lateral mesoderm induction. However, recent molecular biology analysis has revealed more complexity among the direct Wnt target genes, with at least ...

Cell Shape and Cell Lineage Conversion
The organization of animal cells in vivo can be categorized as being either epithelial or mesenchymal. Inter-conversions between these two states, epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET), often represent key ...

A case series study of omphalocele with associated anomalies: An embryogenic imperfection
Omphalocele is a developmental aberration which occurs during embryonic period in the fetal life. The fault in complete closure of the anterior abdominal wall leading to protrusion of the abdominal viscera mainly the small and large intestines with the ...

Innate pluripotency of mouse embryos transits from naive to primed state as the inner cell mass differentiates into epiblast. In vitro, their counterparts are embryonic (ESCs) and epiblast stem cells (EpiSCs), respectively.
