| | Drosophila tissue and organ development: Mesoderm and muscle |
 | | The somatic muscles, the heart, the fat body, the somatic part of the gonad and most of the visceral muscles are derived from a series of segmentally repeated primordia in the Drosophila mesoderm. | | | This work describes the early development of the fat body and its relationship to the gonadal mesoderm, as well as the genetic control of the development of these tissues. | | | This is an elegant mechanism for controlling muscle fiber differentiation during myogenesis, and may have evolved as a way to ensure that muscle primordia develop into muscles that meet the diverse demands placed on them by the nervous system (Fernandes, 2005). |

| | Mesoderm |
| | Because the mesoderm can form different ways in relation to the developing embryo's ectoderm, this is used as a method of categorizing animals. | | | The mesoderm is also believed to be responsible for the formation of the central nervous system, for example the notochord is responsible for releasing certain factors which induce the ectoderm to become neural tissue. | | | The mesoderm gives rise to tissues including connective tissue, muscles and the circulatory system. |

| | Our current work with these pathways has progressed along 3 paths: | | | For example, homodimers of Twist activate the myogenic pathway, whereas heterodimers of Twist and the bHLH protein, Daughterless, repress this pathway. | | | Twist, a basic Helix-loop-Helix (bHLH) transcription factor, plays a critical role at 4 different times during mesoderm development: the specification of the mesoderm; the subdivision of the mesoderm into progenitors of different tissues; the patterning of one of these tissues -- the body muscles; and the differentiation of the adult muscle progenitors. |

| | The mesoderm is the germ layer that forms many muscles, the circulatory and excretory systems, and the dermis, skeleton, and other supportive and connective tissue. | | | Continued cell movement results in an invagination of the bottom region of the embryo, producing a form that resembles a double-layered cup. | | | mesoderm, in biology, middle layer of tissue formed in the gastrula stage of the developing embryo. |

| | The myotome differentiates to form 2 components dorsally the epimere and ventrally the hypomere, which in turn form epaxial and hypaxial muscles respectively. | | | The mesoderm forms nearly all the connective tissues of the musculoskeletal system. | | | Each tissue (cartilage, bone, and muscle) goes through many different mechanisms of differentiation. |

| | Animal - Wikipedia, the free encyclopedia |
| | In most protostomes cells simply fill in the interior of the gastrula to form the mesoderm, called schizocoelous development, but in deuterostomes it forms through evagination of the endoderm, called enterocoelic pouching. | | | In most cases, a mesoderm also develops between them. | | | Deuterostomes also have a dorsal, rather than a ventral, nerve chord and their embryos undergo different cleavage. |

| | The induction and development of mesoderm can also be carried out in vitro for further study of differentiation factors. | | | BMP-related growth factors cause both mesoderm induction in the blastula stages and pattering of ventral mesoderm in the gastrula stages (73). | | | Thus BMP-4 is the major signaling molecule responsible for the induction of ventral mesoderm in the Xenopus gastrulae, the site where hematopoietic induction occurs and all hematopoietic stem cells are derived (67). |
