BACKGROUND: Reference intervals for leukocyte subsets from peripheral blood are helpful for the understanding of disease states and therapy effects. METHODS: We performed in-depth immunophenotyping for 608 healthy German adults from the Leipzig region from 40 to 79 years by 10-color flow cytometry (FCM) to gain reference information for various leukocyte subsets including subsets of granulocytes, monocytes and lymphocytes. RESULTS: First, we derived gender- and age-specific reference intervals ...

Recent technological advances in single-cell genomics make it possible to analyze cellular heterogeneity of tumor samples. Here, we applied single-cell RNA-seq to measure the transcriptomes of 307 single cells cultured from three biopsies of three different patients with a BRAF/NRAS wild type, BRAF mutant/NRAS wild type and BRAF wild type/NRAS mutant melanoma metastasis, respectively. Analysis based on self-organizing maps identified sub-populations defined by multiple gene expression modules ...

Single-cell transcriptomics has been used for analysis of heterogeneous populations of cells during developmental processes and for analysis of tumor cell heterogeneity. More recently, analysis of pseudotime (PT) dynamics of heterogeneous cell populations has been established as a powerful concept to study developmental processes. Here we perform PT analysis of 3 melanoma short-term cultures with different genetic backgrounds to study specific and concordant properties of PT dynamics of selected ...

For this study, we screened prospectively recruited patients with a histopathological reference diagnosis of cerebral tumors of WHO grade II and III, known KPS at diagnosis, information on extent of resection by early postoperative neuroimaging, available frozen tissue specimens from the initial operation, and documented clinical outcome.

Molecular profiling of cerebral gliomas distinguishes biologically distinct tumor groups and provides prognostically relevant information beyond histological ...

ROIs of size 600 x 900 px (0.109 mm^2) size were chosen from 25 expert-specified tumor subregions within DLBCL biopsy specimens. Images were generated by Hamamatsu Nanozoomer 2.0 RS slide scanner. ROI no. 1 - 25 represent staining with CD14 antibody (imaged at 488 nm wavelength), ROI no. 26 -- 50 represent staining with CD163 antibody (imaged at 555 nm wavelength). Imaged regions in ROIs no. 1 and 26, 2 and 27, ... , coincide. Data were used for mutual comparison of automated macrophage recognition ...
