  1. 1. The role of Six1 in muscle progenitor cells and the establishment of fast-twitch muscle fibres

    Author : Hanna Nord; Jonas von Hofsten; Freek van Eeden; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Myogenesis; zebrafish; muscle fibre; patterning; fmyhc; myl1; Six1; Pax7;

    Abstract : Myogenesis is the process of skeletal muscle tissue formation where committed muscle progenitor cells differentiate into skeletal muscle fibres. Depending on the instructive cues the muscle progenitor cells receive they will differentiate into specific fibre types with different properties. READ MORE

  2. 2. The Physical Foundation of the Patterning of Physical Action Verbs : A Study of Chinese Verbs

    Abstract : This work is a study of verbal semantics with a focus on the discussion and illustration of the role of body parts and the semantic incorporation into verbal roots of the actions that involve various body parts. Following a general discussion of the basic issues of language construction and human body actions with the image schemas of force-dynamics presented in line with the framework of cognitive semantics, it is argued that the event structures of physical action verbs are not arbitrarily constructed but rather the constructions are built through systematic cognitive processes in relation to both human physical reality and concrete reality in the world.

  3. 3. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

    Author : Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE

  4. 4. Regulation of morphogen signalling during neural patterning in the Xenopus embryo

    Author : Hooi Min Tan Grahn; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Suppressor-of-fused; Gli; β-Catenin; Neural; Xenopus; FGF; Signalling; HtrA1; RDH10; Retinol dehydrogenase; Retinoic acid; Spemann s organizer; Induction; Gradient;

    Abstract : Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xenopus embryo. READ MORE

  5. 5. Investigation of Hox gene expression and Wnt-signalling in basally branching ecdysozoans

    Author : Mattias Hogvall; Ralf Janssen; Graham Budd; Andreas Hejnol; Andrew Peel; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Wnt signalling pathway; Hox genes; Fz receptors; Onychophora; Priapulida; Ecdysozoa; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Abstract : One of the most important processes in the development of an animal is the determination and patterning of the primary body axis, the anterior-posterior (AP) axis. After the AP axis has been established the embryo grows and elongates through posterior elongation. READ MORE
