Mesenchyme: Mesenchyme is a type of tissue characterized by loosely associated cells that lack polarity and are surrounded by a large extracellular matrix. Mesenchymal cells are able to develop into the tissues of the lymphatic and circulatory systems, as well as connective tissues throughout the body, such as bone and cartilage.Multiple patterning: Multiple patterning (or multi-patterning) is a class of technologies for manufacturing integrated circuits (ICs), developed for photolithography to enhance the feature density. The simplest case of multiple patterning is double patterning, where a conventional lithography process is enhanced to produce double the expected number of features.Yolk sac: The yolk sac is a membranous [attached to an embryo], formed by cells of the [[hypoblast adjacent to the embryonic disk. This is alternatively called the umbilical vesicle by the Terminologia Embryologica (TE), though yolk sac is far more widely used.Human embryonic stem cells clinical trials: ==Human Embryonic Stem Cell Clinical Trials==Iroquois homeobox factor: Iroquois homeobox factors are a family of homeodomain transcription factors that play a role in many developmental processes.Lineage markers: The lineage markers are characteristic molecules for cell lineages, e.g.Activin and inhibin: Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Identified in 1986, activin enhances FSH biosynthesis and secretion, and participates in the regulation of the menstrual cycle.Pituitary-specific positive transcription factor 1: POU domain, class 1, transcription factor 1 (Pit1, growth hormone factor 1), also known as POU1F1, is a transcription factor for growth hormone.High mobility group protein HMG14 and HMG17: High mobility group protein HMG14 and HMG17 also known as nucleosomal binding domain is a family of evolutionarily related proteins.Morphant: An organism which has been treated with a morpholino antisense oligo to temporarily knock down expression of a targeted gene is called a morphant.Immunosurgery: Immunosurgery is a method of removing an external cell layer of an object. Immunosurgery is to expose the specimen to a solution containing antibodies against the object, remove that solution and subsequently expose the object to complement.Stomochord: The stomochord is a flexible, hollow tube found in hemichordates. Stomochords arise in embryonic development as an outpocketing from the roof of the embryonic gut anterior to the pharynx.T-box: coordinates.TeratomaPancreatic bud: The ventral and dorsal pancreatic buds (or pancreatic diverticula) are outgrowths of the duodenum during human embryogenesis. They join together to form the adult pancreas.Fork head domainMidblastula: In developmental biology, midblastula or midblastula transition (MBT) is a stage during the blastula stage of embryonic development in which zygotic gene transcription is activated. There are three major characteristics of pre-MBT embryos.Chimera (EST): In genetics, a chimera is a single cDNA sequence originating from two transcripts. It is usually considered to be a contaminant in transcript and expressed sequence tag (EST) databases.Old World quail: Old World quail is a collective name for several genera of mid-sized birds in the pheasant family Phasianidae.A. Hari ReddiTretinoinFGF15/19: FGF15/19 refers to two orthologous fibroblast growth factors which share 50% aminoacid identity and have similar functions.DNA-binding proteinPhallusia nigraHomeotic gene: Homeotic genes are genes which regulate the development of anatomical structures in various organisms such as insects, mammals, and plants. This regulation is done via the programming of various transcription factors by the homeotic genes, and these factors affect genes through regulatory genetic pathways.Renal stem cell: Renal stem cells are self-renewing, multipotent stem cells which are able to give rise to all the cell types of the kidney. It is involved in the homeostasis and repair of the kidney, and holds therapeutic potential for treatment of kidney failure.Enteric duplication cyst: Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract.Wnt signaling pathway: The Wnt signaling pathways are a group of signal transduction pathways made of proteins that pass signals from outside of a cell through cell surface receptors to the inside of the cell. Three Wnt signaling pathways have been characterized: the canonical Wnt pathway, the noncanonical planar cell polarity pathway, and the noncanonical Wnt/calcium pathway.Coles PhillipsSea urchin injury: Sea urchin injuries are caused by contact with sea urchins, and are characterized by puncture wounds inflicted by the animal's brittle, fragile spines.Pioneer factor: Pioneer factors are transcription factors that can directly bind condensed chromatin. They can have positive and negative effects on transcription and are important in recruiting other transcription factors and histone modification enzymes as well as controlling DNA methylation.Embryonal carcinoma: -9072 |Christoph MangoldPluripotency (biological compounds): The pluripotency of biological compounds describes the ability of certain substances to produce several distinct biological responses. Pluripotent is also described as something that has no fixed developmental potential, as in being able to differentiate into different cell types in the case of pluripotent stem cells.Matrix model: == Mathematics and physics ==
