Embryogenesis of the peristaltic reflex [PDF]

The Journal of Physiology, 2019
Key points Neurogenic gut movements start after longitudinal smooth muscle differentiation in three species (mouse, zebrafish, chicken), and at E16 in the chicken embryo. The first activity of the chicken enteric nervous system is dominated by inhibitory neurons. The embryonic enteric nervous system electromechanically couples circular and longitudinal

A new microspore embryogenesis system under low temperature which mimics zygotic embryogenesis initials, expresses auxin and efficiently regenerates doubled-haploid plants in Brassica napus [PDF]

, 2012
BackgroundMicrospore embryogenesis represents a unique system of single cell reprogramming in plants wherein a highly specialized cell, the microspore, by specific stress treatment, switches its fate towards an embryogenesis pathway. In Brassica napus, a

Migration of primordial germline cells is negatively regulated by surrounding somatic cells during early embryogenesis in Drosophila melanogaster

Вавиловский журнал генетики и селекции, 2020
Cell migration is an important morphogenetic process necessary at different stages of individual development and body functioning. The initiation and maintenance of the cell movement state requires the activation of many factors involved in the ...

Expression of Genes Involved in ABA and Auxin Metabolism and LEA Gene during Embryogenesis in Hemp

Plants, 2022
The level of phytohormones such as abscisic acid (ABA) and auxins (Aux) changes dynamically during embryogenesis. Knowledge of the transcriptional activity of the genes of their metabolic pathways is essential for a deeper understanding of embryogenesis ...

The small intestinal mucosa and its stem cells

Journal of Pediatric and Neonatal Individualized Medicine, 2016
In the first part of this review a brief summary of the embryology and histology of the gastrointestinal tract is provided. In the second part intestinal stem cells (ISCs) are discussed. Several signaling pathways play a crucial role in the crypt base in

The Role of Mitochondria in Human Fertility and Early Embryo Development: What Can We Learn for Clinical Application of Assessing and Improving Mitochondrial DNA?

Cells, 2022
Mitochondria are well known as ‘the powerhouses of the cell’. Indeed, their major role is cellular energy production driven by both mitochondrial and nuclear DNA.

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 ...

Embryogenesis in Hydra

The Biological Bulletin, 1997
Embryogenesis in hydra includes a variable period of dormancy; and this period, as well as subsequent stages through hatching, takes place within a thick cuticle that hinders observation. Thus, although the early stages of development have been well-characterized qualitatively, the middle and later stages are only poorly understood.

Fluorescence fluctuation analysis of Arabidopsis thaliana somatic embryogenesis receptor-like kinase and brassinosteroid insensitive 1 receptor ologomerization. [PDF]

, 2008
Receptor kinases play a key role in the cellular perception of signals. To verify models for receptor activation through dimerization, an experimental system is required to determine the precise oligomerization status of proteins within living cells ...
