Review of Short Phrases and Links

    This Review contains major "Embryogenesis"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Embryogenesis is the process by which the embryo is formed and develops, until it develops into a fetus.
  2. Embryogenesis is a crucial period in the development of eukaryotes.
  3. In embryogenesis, the skeletal system is derived from the mesoderm germ layer.
  4. Plant embryogenesis is a sexual or asexual reproductive process that forms new plants.
  5. During embryogenesis, the murine Pomt1 gene is prominently expressed in the neural tube, the developing eye, and the mesenchyme.

Structure

  1. In the anatomy of an embryo, the somatopleure is a structure created during embryogenesis when the lateral mesoderm splits into two layers.

Critical

  1. For this it is critical that the ducts are exposed to testosterone during embryogenesis.

Study

  1. Laptikhovsky V.V. 1999. Improved mathematical model to study the duration of embryogenesis in cephalopod molluscs.

Role

  1. Role of threonines in the Arabidopsis thaliana somatic embryogenesis receptor kinase 1 activation loop in phosphorylation.

Expression

  1. This expression was maintained throughout embryogenesis and was progressively restricted to the tip of the embryonic root (Figure 4 D and unpublished data).
  2. Transient and restricted expression during mouse embryogenesis of Dll1, a murine gene closely related to Drosophila Delta.

Failure

  1. Pancreas divisum is a failure of the dorsal and ventral pancreatic ducts to fuse during embryogenesis.

Place

  1. As the result of the simulation, we found that some phenomena taking place in Drosophila's early embryogenesis are understandable.

Third Week

  1. The pituitary develops in the third week of embryogenesis from interactions between the diencephalon part of the brain and the nasal cavity.

First Trimester

  1. Disturbance of embryogenesis in the first trimester of gestation by some unknown insult leads to failure of the callosal axons to pass across the midline.

Disease

  1. However, the role of HMGB1 in bone and cartilage that undergo remodeling during embryogenesis, tissue repair, and disease is largely unknown.
  2. The zebrafish is a powerful model system for the genetic analysis of vertebrate embryogenesis, organ development, and disease.

Late Stages

  1. The basic mushroom body structure, including the denritic calyx, peduncle, and lobes, was already visible by the late stages of embryogenesis.

Neural Tube

  1. Spina bifida, among the most common, results from failure of the neural tube and the vertebral bones to close during embryogenesis.

Neural Tube Closure

  1. This phenomenon results from failure of neural tube closure in the mid- and hindbrain regions during early embryogenesis (Fig.

Cell Cycle

  1. This is associated with alterations to the cell cycle in endosperm, a nutritive tissue that supports embryogenesis and seed germination.

Complex Process

  1. In nature, the fertilized egg cell undergoes a complex process known as embryogenesis to become a mature phenotype.

Skeletal System

  1. Growth and development Cartilage in fetal development In embryogenesis, most of the skeletal system is derived from the mesoderm germ layer.

Germ Layers

  1. The endoderm is one of the germ layers formed during animal embryogenesis.

Gestational Age

  1. Changes by weeks of gestational age See also: embryo and Human embryogenesis A 10mm embryo from an ectopic pregnancy, still in the oviduct.

Humans

  1. In humans, when embryogenesis finishes, by the end of the 10th week of gestational age, the precursors of all the major organs of the body have been created.

Germination

  1. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination.

Holoprosencephaly

  1. Cyclopia may be associated with holoprosencephaly, the most common developmental defect of the forebrain with an incidence of 1:250 during embryogenesis.

Process

  1. Embryogenesis: The process of embryo initiation and development.
  2. Plant embryogenesis refers to the process of development of plant embryos, being either a sexual or asexual reproductive process that forms new plants.

Stages

  1. Developmental toxicity induced during early stages of mammalian embryogenesis.

Drosophila

  1. The blastoderm stage of Drosophila embryogenesis is a time of crucial transitions in RNA transcription, the cell cycle and segment determination.
  2. Translational control is critical for early Drosophila embryogenesis and is exerted mainly at the gene level.
  3. We have taken a similar approach to a genome-level investigation of translational regulation during early embryogenesis in Drosophila.

Vertebrates

  1. Noticeably, the respective orthologue genes in vertebrates are widely expressed in neuronal precursors during embryogenesis.

Genes

  1. The normal course of mammalian embryogenesis depends on the correct temporal and spatial regulation of a large number of genes and tissues.
  2. Genes specifically induced during somatic embryogenesis may play key roles in plant embryo development.

Transcripts

  1. To clearly define the profile of hsp23 expression during embryogenesis, the distribution of its transcripts and protein species were both assessed.
  2. We analyzed the translational status of transcripts during early embryogenesis in a genome-wide approach (Figure 1).

Cells

  1. During embryogenesis, Hsp27 associates to cells of the brain and of the ventral nerve cord while Hsp26 is found exclusively in the gonads [ 25].
  2. Embryogenesis in plants can commence from cells other than the fertilized egg cell.

Ectoderm

  1. Ectoderm The ectoderm is the primary germ layer which emerges first during embryogenesis and forms from the outermost of the germ layers.
  2. Here we use time-lapse analysis of Drosophila embryogenesis to show that oenocytes delaminate from the ectoderm in discrete bursts of three.

Zygote

  1. Embryogenesis in plants is a unique process in the sense that it can be initiated from a wide range of cells other than the zygote.
  2. A blastocoele forms during embryogenesis when a zygote (a fertilized ovum) divides into many cells through mitosis.
  3. The zygote then implants itself in the wall of the uterus, where it begins the processes of embryogenesis and morphogenesis.

Fertilization

  1. Fertilization and embryogenesis Double fertilization refers to a process in which two sperm cells fertilize two cells in the ovary.
  2. The stages from fertilization through hatching are known collectively as embryogenesis.

Patterning

  1. Patterning of the external genitalia during embryogenesis is a complex process, yet it has been poorly understood at a molecular level.
  2. Induction and patterning of the mesodermal germ layer is a key early step of vertebrate embryogenesis.

Bicuspids

  1. Lower premolars (bicuspids) have a mesial invagination (groove) of the root sheath, formed during embryogenesis.

Blastocyst

  1. The blastocyst is a structure formed in the early embryogenesis of mammal s, after the formation of the morula, but before implantation.
  2. The blastocyst is a structure formed in the early embryogenesis of mammals, after the formation of the morula.

Gastrulation

  1. In mice, gastrulation occurs after implantation of the embryo, on day 6 of mouse embryogenesis (E6).
  2. In mammals, gastrulation occurs after implantation, around day 16 after fertilization in human embryogenesis.
  3. In humans, gastrulation occurs after implantation, around days 14-16 after fertilization in human embryogenesis.

Organogenesis

  1. These processes are important during embryogenesis and organogenesis [ 19 - 21].

Germ

  1. A germ layer is a collection of cells, formed during animal embryogenesis.
  2. A germ layer is a collection of cells, formed during animal and mammalian embryogenesis.

Embryo

  1. The hormones auxin, gibberellic acid, and cytokinin all stimulate growth and are present in the embryo during the stages of embryogenesis.
  2. The development of the embryo is called embryogenesis.
  3. Embryogenesis is the process by which the embryo is formed and develops.

Embryogenesis

  1. These stages are categorized as the periods of embryogenesis (cleavage and gastrulation) and organogenesis (formation of organs and organ systems).
  2. This process of germ layer formation is called gastrulation and is the beginning of embryogenesis.
  3. Teratology is concerned with all features of abnormal generation and development of the embryo (embryogenesis) and their end products.
