Endothelium - protection and support for embryo sac [PDF]

, 2013
Endothelium jest tkanką zlokalizowaną w zalążkach gatunków, należących głównie do rodziny Asteraceae. Otacza rozwijający się gametofit żeński (woreczek zalążkowy), a w wyniku zapłodnienia - zarodek oraz bielmo, odżywiając je i izolując od miękiszowych ...

Halogenated Tryptophans Improve Integrin αVβ6 Affinity of Cyclic RGD Peptides and Provide Handles for Late‐Stage Derivatization

Chemistry – A European Journal, EarlyView.
Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Embryonic stem cells: modelling effects ofearly embryo environment

, 2013
The Developmental Origins of Health and Disease (DOHaD) hypothesis proposes that embryonic environment can induce permanent changes in metabolism during development, increasing the risk of disease in adults. Adverse environments during critical stages of

High temperature-induced triploid production during embryo sac development in Populus

, 2012
Triploid breeding plays an important role in cultivar improvement in the genus Populus L. A novel approach for triploid production with colchicine during embryo sac development was reported recently by Wang et al. (2010).

Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

Developmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.
