  1. 1. Specification of the lens and olfactory placodes and dorsoventral patterning of the telencephalon

    Författare :My Sjödal; Juha Partanen; Umeå universitet; []
    Nyckelord :telencephalon; olfactory; lens; BMP; RA; FGF; Wnt; development; placode; gradient; chick; nervous system; dorsoventral; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Sammanfattning : The vertebrate nervous system is a highly complex and intriguing structure with diverse functions. To understand the functional nervous system, we first have to be aware of how it is assembled during development. LÄS MER

  3. 2. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube

    Författare :Esther Maier; Lena Gunhaga; Fernando Giraldez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory placode; caudal neural tube; Wnt; FGF; RA; BMP; Notch; patterning; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. LÄS MER

  4. 3. BMP - a key signaling molecule in specification and morphogenesis of sensory structures

    Sammanfattning : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. LÄS MER
