Using intravital microscopy, they obtained a subcellular-resolution image of the tumor blood vessels in living subjects.156 Cai et al.157 have also used the RGD peptide-labeled QDs to image tumor blood vessels in vivo. The QDs used were QD705-RGD, a near-infraredQD. Their experiments showed...
Deep learning, a subset of machine learning, has revolutionized the field of medical image analysis, offering substantial improvements in detecting and classifying various diseases [3]. In brain tumor detection, deep learning algorithms can analyze complex MRI data, identify patterns imperceptible to the...
and a crucial resource is the open ImageNet database4which contains more than 14 million labeled images. Techniques developed in computer vision are rapidly transferred to the medical imaging field, but a major constraint is that access to medical images is much more complicated due to ethics, ...
Full size image In particular, our analysis revealed clusters of epithelial cells with transcriptional profiles unique for the tumor context. This included luminal- and basal-like cells as well as a small but distinct cancer stem cell (CSC)-like population in which Wnt-specific genes were activate...

Metastatic colonization is one of the critical steps in tumor metastasis. A pre-metastatic niche is required for metastatic colonization and is determined by tumor-stroma interactions, yet the mechanistic underpinnings remain incompletely understood. PCR
Image gray values were normalized by linearly mapping the 2nd and 98th gray value percentiles, computed within a liver mask, to 0 and 1 without clipping values outside this interval. All pre-processing was performed in MeVisLab14 (MeVis Medical Solutions, Germany). The extracted patches (see ...
Tumor-derived factors are thought to regulate thrombocytosis and erythrocytopenia in individuals with cancer; however, such factors have not yet been identified. Here we show that tumor cell-released kynurenine (Kyn) biases megakaryocytic–erythroid prog
