Genes, proteins and other networks regulating somatic embryogenesis in plants
Journal of Genetic Engineering and Biotechnology, 2020 Somatic embryogenesis (SE) is an intricate molecular and biochemical process principally based on cellular totipotency and a model in studying plant development.

eLife, 2015 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.

Plant Methods, 2020 Optimizing the somatic embryogenesis protocol can be considered as the first and foremost step in successful gene transformation studies. However, it is usually difficult to achieve an optimized embryogenesis protocol due to the cost and time-consuming ...

Ras-dva small GTPases lost during evolution of amniotes regulate regeneration in anamniotes
Scientific Reports, 2018 In contrast to amniotes (reptiles, birds and mammals), anamniotes (fishes and amphibians) can effectively regenerate body appendages such as fins, limbs and tails. Why such a useful capability was progressively lost in amniotes remains unknown.

African Journal of Paediatric Surgery, 2022 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.

Somatic Embryogenesis in Elm [PDF]
Annals of Botany, 2002 We show that isolated zygotic embryos of Ulmus minor and U. glabra can produce embryogenic cultures provided they are isolated from immature seeds before storage proteins begin to accumulate. Rates of somatic embryogenesis were highest among zygotic embryos collected 6 weeks post-anthesis when they were at the midcotyledonary stage, were about 5 mm ...

Signaling Overview of Plant Somatic Embryogenesis
Frontiers in Plant Science, 2019 Somatic embryogenesis (SE) is a means by which plants can regenerate bipolar structures from a somatic cell. During the process of cell differentiation, the explant responds to endogenous stimuli, which trigger the induction of a signaling response and ...

The molecular genetics of RASopathies: An update on novel disease genes and new disorders
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, Volume 190, Issue 4, Page 425-439, December 2022., 2022 Abstract Enhanced signaling through RAS and the mitogen‐associated protein kinase (MAPK) cascade underlies the RASopathies, a family of clinically related disorders affecting development and growth. In RASopathies, increased RAS‐MAPK signaling can result from the upregulated activity of various RAS GTPases, enhanced function of proteins positively ...

Brownian-like deviation of neighboring cells in the early embryogenesis of the zebrafish [PDF]
Physical Biology, Institute of Physics: Hybrid Open Access, 2019,
16 (2), pp.024001, 2019 We investigate cell trajectories during zebrafish early embryogenesis based on 3D+time photonic microscopy imaging data. To remove the collective flow motion and focus on fluctuations, we analyze the deviations of pairs of neighboring cells. These deviations resemble Brownian motion and reveal different behaviors between pairs containing daughter cells

Mechanochemical models for calcium waves in embryonic epithelia [PDF]
Vietnam Journal of Mathematics, volume 50, pages 947-975, year
2022, 2021 In embryogenesis, epithelial cells, acting as individual entities or as coordinated aggregates in a tissue, exhibit strong coupling between chemical signalling and mechanical responses to internally or externally applied stresses. Intercellular communication in combination with such coordination of morphogenetic movements can lead to drastic ...
