    Abstract : We have used the chicken retina as a model for investigating cell cycle regulation and cell fate commitment during central nervous system development. This thesis focuses on the characterization of and commitment to the horizontal cell fate in the retina. READ MORE

  5. 3. Regulation of productivity in Trichoplusia ni and Spodoptera frugiperda Sf9 serum-free cultures

    Author : Karin Calles; Lena Häggström; Gunnel Dalhammar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Insect cells; BEVS; Spodoptera frugiperda; Sf9; Trichoplusia ni; BTI-Tn-5B1-4; specific productivity; conditioned medium; conditioned medium factors; cell cycle; synchronization; G2 M; Bioteknik; Bioengineering; Bioteknik;

    Abstract : The aim of this work has been to characterize the effects of conditioned medium (CM) on insect cell productivity and physiology in order to get a better understanding about the mechanisms that regulate productivity in serum-free media. Two cell lines have been investigated, Spodoptera frugiperda (Sf9) and Trichoplusia ni (T. ni, BTI-Tn-5B1-4). READ MORE

  7. 5. Quiescent regimes in cosmology

    Author : Hans Oude Groeniger; Hans Ringström; Mattias Dahl; Todd Oliynyk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quiescence; Bianchi spacetimes; big bang formation; G2 cosmology; Wainwright-Hsu variables; Klein-Gordon equation; Matematik; Mathematics;

    Abstract : This thesis is about cosmological solutions to Einstein’s equations of general relativity, in particular spacetimes whose mean curvature diverges. Moreover, we consider anisotropic spacetimes with big bang singularities. In this setting the singularity is expected to generically be oscillatory if no matter is present. READ MORE
