| Outline of Final Research Achievements |
In order to fulfill their promise in regenerative medicine and drug discovery, a steady supply of iPS cells obtained through harvesting of individual cell colonies is needed. However, cultivating iPS cell colonies is a sensitive process, and even if care is taken abnormalities can appear, which need to be detected. It is therefore important to automate the process of detecting such abnormalities and in this research project we have designed a new deep learning based semantic segmentation algorithm which is able to automatically detect and label at pixel level differentiated vs. undifferentiated cells in iPS colonies images.
