   Sammanfattning : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. LÄS MER

3. 2. Three dimensional mathematical modelling of pronuclei migration for the mouse

   Författare :Sofia Tapani; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fertilisation process; pronucleus; dynamical simulation; SDE; correlation; CUSUM; microtubule; confocal microscopy; dynamical simulation;

   Sammanfattning : The main question addressed in this thesis is what happens between the moment when the sperm enters the egg and the fusion of the male and the female pronuclei. Orientation of the apposing pronuclei most likely plays a decisive role in the polarity of the developing embryo. LÄS MER

4. 3. Time-Lapse Microscopy Imaging and Image Analysis for Cell Migration Studies

   Författare :Johan Degerman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cell image segmentation; computational imaging; cell migration modelling; Time-lapse microscopy;

   Sammanfattning : This thesis considers a complete automatic system for in-vitro cell imaging and migration image analysis. The development of such can be divided into three main problems:The first considered problem concerns how to build a robust time-lapse sequence acquisition system, for imaging adult hippocampal cells in bright-field microscopy.

5. 4. Mathematical Modelling of Cell Migration and Polarization

   Författare :Adam Malik; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Cell migration plays a fundamental role in both development and disease. It is a complex process during which cells interact with one another and with their local environment. Mathematical modelling offers tools to investigate such processes and can give insights into the underlying biological details, and can also guide new experiments. LÄS MER

7. 5. Systems microscopy analysis of cell migration

   Författare :Hamdah Shafqat Abbasi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Single cell migration is heterogeneous and a complicated process. It arises from a hugely complex network of multi-scale interactions between molecular and macromolecular entities. LÄS MER
