A new multi-resolution super-pixel based algorithm is proposed to track cell size, count and motion in Mesenchymal Stem Cells (MSCs) images. Multi-resolution super-pixels are obtained by placing varying density seeds on the image. The density of the seeds are determined according to the local high frequency components of the MSCs image. In this way a multi-resolution super-pixels decomposition of the image is obtained. A second contribution of the paper is novel decision rule for merging similar neighboring super-pixels. An algorithm based on well known wavelet decomposition is developed and applied to the histograms of neighboring super pixels to exploit similarity. The proposed algorithm is experimentally shown to be successful in segmenting and tracking cells in MSCs images.

MULTI-RESOLUTION SUPER-PIXELS AND THEIR APPLICATIONS ON FLUORESCENT MESENCHYMAL STEM CELLS IMAGES USING 1-D SIFT MERGING

DeepDistance: A multi-task deep regression model for cell detection in inverted microscopy images
Koyuncu, Can Fahrettin; Gunesli, Gozde Nur; Atalay, Rengül; GÜNDÜZ DEMİR, Çiğdem (Elsevier BV, 2020-07-01)
This paper presents a new deep regression model, which we call DeepDistance, for cell detection in images acquired with inverted microscopy. This model considers cell detection as a task of finding most probable locations that suggest cell centers in an image. It represents this main task with a regression task of learning an inner distance metric. However, different than the previously reported regression based methods, the DeepDistance model proposes to approach its learning as a multi-task regression pro...
Hydrogels as a New Platform to Recapitulate the Tumor Microenvironment
Hasırcı, Nesrin; Ermiş Şen, Menekşe; Güven, Sinan; Durmuş, Gözde; Rizvi, İmran; Hasan, Tayyaba; Demirci, Utkan; Hasırcı, Vasıf Nejat (Elsevier Science, 2018-06-01)
Recent advances in tissue engineering include the incorporation of multiple cell types into three-dimensional (3D) hydrogels to recapitulate extracellular matrix (ECM) structures and the functionality of living tissues in vitro. For decades, researchers have been investigating the complex mechanisms of cancer metastasis, tumorigenesis, and angiogenesis over two-dimensional (2D) monolayer cell culture models, or in vivo animal models. Increasing numbers of unsuccessful clinical trials for cancer therapy indi...

Osteogenic differentiation of adipose derived stem cells on high and low aspect ratio micropatterns
Sayin, Esen; Baran, Erkan Turker; Hasırcı, Vasıf Nejat (2015-12-12)
Adipose derived stem cells (ADSCs) were cultured on collagen-silk fibroin films with microchannel and micropillar patterns to investigate the effects of cell morphology changes on osteogenic differentiation. Channel and pillar micropatterned films were prepared from collagen type I and silk fibroin. While higher ADSC proliferation profiles were obtained on micropillar blend film, microchannel blend films, however, caused twice higher aspect ratio and effective orientation of cells. Alkaline phosphatase acti...
