Molecular recording of mammalian embryogenesis. [PDF]
bioRxiv, 2019Ontogeny describes the emergence of complex multicellular organisms from single totipotent cells. This field is particularly challenging in mammals, owing to the indeterminate relationship between self-renewal and differentiation, variation in progenitor

Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley [PDF]
Journal of Experimental Botany, 2018Microspores are reprogrammed towards embryogenesis by stress. Many microspores die after this stress, limiting the efficiency of microspore embryogenesis. Autophagy is a degradation pathway that plays critical roles in stress response and cell death.

The effects of sugars and growth regulators on embryo- and callusogenesis in isolated ovules culture of beetroot, Beta vulgaris L. [PDF]
Caspian Journal of Environmental Sciences, 2021Haploid 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.

Genetic and Molecular Control of Somatic Embryogenesis
Plants, 2021Somatic embryogenesis is a method of asexual reproduction that can occur naturally in various plant species and is widely used for clonal propagation, transformation and regeneration of different crops. Somatic embryogenesis shares some developmental and

Regulatory principles governing the maternal-to-zygotic transition: insights from Drosophila melanogaster [PDF]
Open Biology, 2018The 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.

Morphological Characterization and Identification of Coffea Liberica Callus of Somatic Embryogenesis Propagation. [PDF]
, 2015Compared with other types of coffee, Liberica coffee is more difficult to be propagates using clonal methods. Meanwhile, demand for planting materials and consumption of this type of coffee is increasing lately.

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]
Journal of Theoretical Biology 551-552 (2022) 111239, 2022There 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 ...
