  • Morula
    anatomy An early embryo that is a compact mass of about 16 BLASTOMERES. It resembles a cluster of mulberries with two types of cells, outer cells and ...
  • Mullerian Ducts
    anatomy A pair of ducts near the WOLFFIAN DUCTS in a developing embryo. In the male embryo, they degenerate with the appearance of ...
  • Muscle Cells
    anatomy Mature contractile cells, commonly known as myocytes, that form one of three kinds of muscle. The three types of muscle cells are skeletal (MUSCLE FIBERS, ...
  • Myoblasts
    anatomy Embryonic (precursor) cells of the myogenic lineage that develop from the MESODERM. They undergo proliferation, migrate to their various sites,...
  • Neural Plate
    anatomy The region in the dorsal ECTODERM of a chordate embryo that gives rise to the future CENTRAL NERVOUS SYSTEM. Tissue in the neural plate is ...
  • Neural Stem Cells
    anatomy Self-renewing cells that generate the main phenotypes of the nervous system in both the embryo and adult. Neural stem cells are precursors to ...
  • Neural Tube
    anatomy A tube of ectodermal tissue in an embryo that will give rise to the CENTRAL NERVOUS SYSTEM, including the SPINAL CORD and the BRAIN. Lumen ...
  • Neurites
    anatomy In tissue culture, hairlike projections of neurons stimulated by growth factors and other molecules. These projections may go on to form a branched tree of ...
  • NIH 3T3 Cells
    anatomy A continuous cell line of high contact-inhibition established from NIH Swiss mouse embryo cultures. The cells are useful for DNA transfection ...
  • Notochord
    anatomy A cartilaginous rod of mesodermal cells at the dorsal midline of all CHORDATE embryos. In lower vertebrates, notochord is the backbone of ...
  • Organizers, Embryonic
    anatomy Cells in certain regions of an embryo that self-regulate embryonic development. These organizers have been found in dorsal and...
  • Primitive Streak
    anatomy A linear band of rapidly proliferating cells that begins near the posterior end of an embryo and grows cranially. Primitive streak is formed ...
  • Pronephros
    anatomy The primordial kidney that develops from the INTERMEDIATE MESODERM in the embryos of vertebrates, and is succeeded by the MESONEPHROS. In ...
  • Prosencephalon
    anatomy The anterior of the three primitive cerebral vesicles of the embryonic brain arising from the NEURAL TUBE. It subdivides to form DIENCEPHALON ...
  • Rhombencephalon
    anatomy The posterior of the three primitive cerebral vesicles of an embryonic brain. It consists of myelencephalon, metencephalon, and isthmus ...
