Theobroma cacao: Somatic Embryogenesis

open access: yes, 2022
AbstractA two-step process combining direct and indirect somatic embryogenesis, on solid and liquid medium, respectively is described forTheobroma cacao L.Staminodes and petals from unopened bud flowers are used to induce primary direct embryos. Then, these primary embryos are cut to produce embryogenic calli which will develop secondary embryos.

Current applications of coffee (Coffea arabica) somatic embryogenesis for industrial propagation of elite heterozygous materials in Central America and Mexico [PDF]

open access: yes, 2010
Of ail the possible micropropagation techniques, it is widely accepted that vegetative propagation by somatic embryogenesis is by far the most promising for rapid, large-scale dissemination of elite individuals.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Sucrose versus maltose effect on metabolic pathways in somatic embryogenesis of Hevea brasiliensis [PDF]

open access: yes, 2004
Somatic embryogenesis in Hevea is stimulated when the embryogenesis induction medium contains maltose, rather than glucose, fructose, or sucrose, in equimolarity (Blanc et al., 1999).

The relationship between cell size and cell fate in Volvox carteri [PDF]

open access: yes, 1993
In Volvox carteri development, visibly asymmetric cleavage divisions set apart large embryonic cells that will become asexual reproductive cells (gonidia) from smaller cells that will produce terminally differentiated somatic cells. Three mechanisms have

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Influence of Abscisic Acid and Sucrose on Somatic Embryogenesis in Cactus Copiapoa tenuissima Ritt. forma mostruosa

open access: yesThe Scientific World Journal, 2013
Having produced the embryos of cactus Copiapoa tenuissima Ritt. forma monstruosa at the globular stage and callus, we investigated the effect of abscisic acid (ABA) in the following concentrations: 0, 0.1, 1, 10, and 100 μM on successive stages of ...

Endogenous levels of reducing sugars, free amino acids and phenols during various stages of in vitro culture of cotton (Gossypium Spp.) [PDF]

open access: yes, 2010
Somatic embryogenesis is widely preferred as the regeneration route for in vitro studies in cotton. However, the regeneration efficiency through this approach is low; a problem that is believed to be as a result of the biochemical properties of the ...

Microengineered Gradient Hydrogels for Mechanobiology

open access: yesAdvanced Healthcare Materials, EarlyView.
Gradient hydrogels are used to mimic the mechanical heterogeneity in native tissues, offering powerful in vitro platforms to study cell‐material interactions in diverse pathophysiological contexts. Here, we present a comprehensive review of the design and experimental considerations for stiffness gradient hydrogels, discussing exemplary achievements ...
