    The mechanisms of primordial germ cell determination during embryogenesis in molluscan species by M Obata, A Komaru

    Published 2012-12-01
    “…Primordial germ cells (PGCs) are the first germ cells distinguishable from surrounding somatic cells during embryogenesis. In many animal species PGC specification is generally classified into two modes: preformation, in which PGCs are determined by maternally inherited components in early development, and epigenesis, in which PGCs arise from proximal somatic cells by inductive signal in late development. …”

    Mouse cofactor of BRCA1 (Cobra1) is required for early embryogenesis. by Asma Amleh, Sreejith J Nair, Jianlong Sun, Ann Sutherland, Paul Hasty, Rong Li

    Published 2009-01-01
    “…Chromatin immunoprecipitation (ChIP) indicates that Cobra1 binds to the Lef1 promoter and modulates the abundance of promoter-bound RNA polymerase.Cobra1 is essential for early embryogenesis. Our findings also indicate that Cobra1 helps maintain the undifferentiated state of mESCs by preventing unscheduled expression of developmental genes.…”

    Somatic Embryogenesis of Representative Medicinal Trees in South America—Current Status by Raluca A. Mihai, Erly J. Melo Heras, Eliza A. Pinto Valdiviezo, Iván A. Espinoza Caiza, Nelson S. Cubi Insuaste, Jean Pierre Mejía, Rodica D. Catana, Mirela M. Moldoveanu, Larisa I. Florescu

    Published 2023-10-01
    “…According to the VOSviewer analyses, very few studies were available concerning aspects of somatic embryogenesis in medicinal trees. From the 10 representative species selected in our study, somatic embryogenesis protocols were established for 3 species, only for conservation purpose, not for secondary metabolites production. …”
