3T3 murine embryonic fibroblasts are used as feeder layers to support the proliferative potential of human primary keratinocytes during in vitro expansion for cell and gene therapy applications. To identify signals mediating this function, we analyzed fibroblast protein content using mass spectrometry. We compared the proteome of lethally irradiated fibroblasts used as feeder layers at two time points: 24 hours and 4 days post-seeding. Our findings highlight differences in extracellular matrix ...

Chemical named entity recognition (NER) is a significant pre-processing task in natural language processing. Identification and extraction of chemical entities from biomedical literature and entities linking to the knowledge base are essential steps for the chemical text-mining pipeline. However, the identification of chemical entities in a biomedical text is a challenging task due to the diverse morphology of chemical entities and the different types of chemical nomenclature. In this work, we ...

Single-cell RNA-sequencing (scRNA-seq) provides high-resolution insights into complex tissues. Cardiac tissue, however, poses a major challenge due to the delicate isolation process and the large size of mature cardiomyocytes. Regardless of the experimental technique, captured cells are often impaired and some capture sites may contain multiple or no cells at all. All this refers to “low quality” potentially leading to data misinterpretation. Common standard quality control parameters involve the ...
