(1) Furthermore, injections into the mesoderm or ectoderm require going through the endoderm layer.

(2) Method: Apply evolution and embryology to set mesoderm theory of chinese channel.

(3) Results: Nascence of epithelioid sarcoma was primary space mesoderm, it is appeared in any part of body, more in upper limbs.

(4) The structure and function of the mesoderm accessory glands and seminal vesicle in Oxya Chinensis (Insecta: Orthoptera), are studied with gland specimen, paraffin sections and light microscopy method.

(5) The middle zone of the mesoderm of a chordate vertebrate embryo, from which excretory tissue develops.

(6) Between the ectoderm and endoderm is mesoderm, which forms the muscles, reproductive organs, blood vessels and excretory organs.

(7) In the embryo an undifferentiated mesodermal component of an early trunk or tail segment or metamere, derived from paraxial mesoderm.

(8) It is involved in mesoderm formation and left - right axis determination.

(9) Mesoderm --- The middle germ layer in the early embryo; the source of cells that go on to make bones, muscles, connective tissue, heart, hematopoietic system, kidney, and other organs.

(10) A segmental mass of mesoderm in the vertebrate embryo, occurring in pairs along the notochord and developing into muscles and vertebrae.

(11) The liver of Alligator sinensis was formed by the endodermal epithelia invigilated from the edge of foregut door and by surrounding mesoderm during early stages of pre-natal development.

(12) Fibroblasts are mesenchymal cells, which are derived from the embryonic mesoderm.

(13) Objective:Endogenous PTEN express in primitive streak during chick embryo gastrulation and mesoderm derived structure later on including heart tubes.

(14) Because one patient only suffers from iris coloboma instead of aniridia , we would like to propose that the primary embryological defect is due to aberrant development of mesoderm.

(15) Germ layer --- One of three distinct layers of cells that arise in the inner cell mass, the ectoderm, mesoderm, and endoderm, each of which develops into a distinctly different tissue in the embryo.

(16) The jaw teeth and pharyngeal teeth are derived from the ectoderm and mesoderm.

(17) Mesenchymal stem cell cultured in vitro adheres to the wall and diplays the fibro-like phenotype and differentiates to the cells of endoderm, mesoderm, ectoderm under certain condition.

(18) The residual cells were able to form teratoma at the injection site, and mature endoderm, mesoderm and ectoderm tissues could be found in teratoma tissues.

(19) These data altogether suggest that Dpr 2 functions to inhibit mesoderm induction mediated by Nodal signaling.

(20) When an animal develops, embryos form three cellular or germ layers - ectoderm, endoderm and mesoderm - which then go on to form the body's organs and tissues.

(21) The vertebral column is derived from somites, which are mesoderm that are present in developing vertebrates.

(22) The little tadpole about the size of a sesame seed is now made up of three layers: the ectoderm mesoderm and endoderm.

(23) A complex sheet of embryonic cells in craniate vertebrates, formed by association of part of the mesoderm with the ectoderm and developing as the internal body wall.

(24) Ectoderm becomes skin and nerves, endoderm becomes the gut and organs such as the liver, pancreas and thymus, and mesoderm becomes muscle, bones and blood.
