  2. 1. Miniaturised Microwell-based Cell Assays

    Author : Emilie Weibull; Helene Andersson Svahn; Albert van den Berg; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microwell; miniaturisation; high-resolution imaging; high-throughput; cell culture; single-cell; clone; heterogeneity; antibiotic susceptibility testing; concentration gradient; interfacing; microchannels; cell retrieval;

    Abstract : Cell heterogeneity in genetically identical cell populations is becoming a well-known and important phenomenon in cell biology. Current methods commonly utilise population-based analysis founded on averaged result. Hence there is a need for high-throughput cell assays on the single-cell level. READ MORE

  4. 2. Microwell devices for single-cell analyses

    Author : Sara Lindström; Helene Andersson-Svahn; Mehmet Toner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microwell; miniaturization; microfluidics; cell culture; single-cell; clone; imaging; stem cell; cancer; low volume; high-throughput; Molecular biology; Molekylärbiologi;

    Abstract : Powerful tools for detailed cellular studies are emerging, increasing the knowledge ofthe ultimate target of all drugs: the living cell. Today, cells are commonly analyzed inensembles, i.e. thousands of cells per sample, yielding results on the average responseof the cells. READ MORE

  5. 3. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Author : Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Abstract : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. READ MORE

  6. 4. Mechanisms regulating Natural Killer Cell Cytotoxicity

    Author : Hanna van Ooijen; Björn Önfelt; Karl-Johan Malmberg; Karolin Guldevall; Morgan Huse; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural Killer cell; Live-cell microscopy; Single cell; 3D; Microwell;

    Abstract : Over the last 50 years, cancer survival rates have steadily improved thanks to earlier detection and novel treatment regimens. For example, drugs that act on the immune system, so-called immunotherapy, have drastically increased the prospect of survival for patients suffering from some of the most aggressive cancer types including advanced malignant melanoma.

  7. 5. Genital human papillomaviruses. Studies of their occurrence, type spectrum and expression

    Author : Ola Forslund; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA expression; microwell; HPV 70; type determination; CIN; quantification; urine; multifocal infections; hybridization; PCR; HPV; human papillomavirus; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The occurrence of genital human papillomavirus infection was determined in different categories of patients by means of PCR. In high proportion of young women attending an adolescent clinic, the presence of HPV DNA was demonstrated in simultaneously urethral and cervical samples, suggesting that genital HPV infections are often multifocal.
