Cell Shape and Cell Lineage Conversion

open access: yesThe Journal of Poultry Science, 2015
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 ...

Five Transcription Factors and FGF Pathway Inhibition Efficiently Induce Erythroid Differentiation in the Epiblast

open access: yesStem Cell Reports, 2014
Primitive erythropoiesis follows a stereotypic developmental program of mesoderm ventralization and internalization, hemangioblast formation and migration, and erythroid lineage specification.

Characterization of the finch embryo supports evolutionary conservation of the naive stage of development in amniotes

open access: yeseLife, 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.

Microspore embryogenesis in barley: anther pre-treatment stimulates plant defence gene expression [PDF]

open access: yes, 2009
Microspore embryogenesis (ME) is a process in which the gametophytic pollen programme of the microspore is reorientated towards a new embryo sporophytic programme.

Ras-dva small GTPases lost during evolution of amniotes regulate regeneration in anamniotes

open access: yesScientific 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.

Methodology for reconstructing early zebrafish development from in vivo multiphoton microscopy [PDF]

open access: yes, 2012
Investigating cell dynamics during early zebrafish embryogenesis requires specific image acquisition and analysis strategies. Multiharmonic microscopy, i.e., second- and third-harmonic generations, allows imaging cell divisions and cell membranes in ...

Mature seeds for in vitro sanitation of the Grapevine leafroll associated virus (GLRaV-1andGLRaV-3) from grape (Vitis vinifera L.)

open access: yesSpanish Journal of Agricultural Research, 2015
The conservation of old grapevine varieties is important since they are adapted to specific climate conditions and may carry genes interesting to breeders.

Proteomic Analysis of S-Nitrosation Sites During Somatic Embryogenesis in Brazilian Pine, Araucaria angustifolia (Bertol.) Kuntze

open access: yesFrontiers in Plant Science, 2022
Cysteine S-nitrosation is a redox-based post-translational modification that mediates nitric oxide (NO) regulation of various aspects of plant growth, development and stress responses.

Essential factors for in vitro regeneration of rose and a protocol for plant regeneration from leaves

open access: yesHorticultural Science, 2018
In vitro propagation of Rosa hybrida, L. cv. 'Eiffel Tower' was improved by the addition of thidiazuron (TDZ) and silver nitrate (AgNo3) to the culture medium.

Virtual spherical-shaped multicellular platform for simulating the morphogenetic processes of spider-like body axis formation

open access: yesFrontiers in Cell and Developmental Biology, 2022
Remodeling of multicellular architecture is a critical developmental process for shaping the axis of a bilaterally symmetric animal body and involves coordinated cell–cell interactions and cell rearrangement.
