  1. 11. Single-cell methodologies for ecological and metabolic mapping of mixotrophic microeukaryotes

    Författare :Javier Florenza; Stefan Bertilsson; Alexandra Z. Worden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mixotrophy; single-cell;

    Sammanfattning : Mixotrophy in aquatic protists is pivotal for our understanding of aquatic microbial food web dynamics. This thesis is centered around aquatic unicellular mixotrophs, and comprises three methodological approaches aimed to tackle mixotroph ecology at single-cell resolution: the identification of actively feeding mixotrophs in natural samples, the determination of specific interactions among mixotrophs and bacterial prey, and the profiling of two distinct mixotrophic populations based on the gene expression of their constitutive individuals.

  3. 12. Imaging-based methods for NK cell studies at the single-cell level

    Författare :Quentin Verron; Björn Önfelt; Niklas Sandström; Michael Dustin; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; NK cells; microscopy; single-cell; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : The immune system provides defense against infectious agents such as viruses, bacteria and parasites. Besides eliminating extracellular agents, the immune system also constantly monitors our own cells for signs of transformation, including tumor development and virus infection. LÄS MER

  4. 13. Droplet microfluidics for single cell and nucleic acid analysis

    Författare :Prem Kumar Periyannan Rajeswari; Helene Andersson Svahn; Håkan Jönsson; Martin Dufva; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Biomarker detection; Cell behavior analysis; Cell factories; Droplet microfluidics; Droplet PCR; High throughput biology; Label-free enrichment; Single cell analysis; Bioteknologi; Biotechnology;

    Sammanfattning : Droplet microfluidics is an emerging technology for analysis of single cells and biomolecules at high throughput. The controlled encapsulation of particles along with the surrounding microenvironment in discrete droplets, which acts as miniaturized reaction vessels, allows millions of particles to be screened in parallel.

  5. 14. Variational methods for phylogeny and single-cell genomics

    Författare :Hazal Koptagel; Jens Lagergren; Alexandre Bouchard-Côté; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Variational inference; single-cell DNA sequencing; cell lineage tree; Bayesian phylogenetic tree inference; Variationsinferens; encellig DNA-sekvensering; cellhärkomstträd; Bayesiansk fylogenetisk trädinferens; Varyasyonel çıkarım; tek hücre DNA dizilimi; hücre soy ağacı; Bayesçi filogenetik ağaç çıkarımı; Datalogi; Computer Science;

    Sammanfattning : The investigation of the evolutionary history of organisms, both at the cellular level and at the species level, is a relevant research topic in computational biology. These investigations lead to a deeper understanding of developmental history, cancer progression, the genetic similarity of species, and more. LÄS MER

  7. 15. Computational Single-Cell Genomics Methods for Cell State Estimation and their Application to Hematopoietic Systems

    Författare :Parashar Dhapola; Avdelningen för molekylär hematologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic Stem Cell; Single-Cell; Genomics; Epigenomics; transcriptomics; bioinformatics;

    Sammanfattning : The focus of this doctoral dissertation was to develop novel and scalable computational genomics methods for analysing single-cell genomic modalities. Scarf, a highly memory-efficient single-cell data analysis toolkit, was developed to enable an analysis of very large-scale datasets on personal computers, and the execution of parallel workflows on server-scale computational systems.
