Cell Atlas Immunocytochemistry Immunofluorescence Organelle Science

30 organelles and substructures are annotated in the Cell Atlas.

The Cell Atlas database was just recently released with data on more than 12.000 proteins and mapping to 30 organelles. Today, the scientific findings are published in Science in "A subcellular map of the humanproteome".

The cell is a complex entity that carries out multiple functions. In order to do this, the different parts of the cells are organized in structures, called organelles. By investigating the organelles and its proteome, and to understand how the proteins vary over time and space we can truly begin to understand human biology on a detailed level...Read more


Tissue Atlas: microscopy and annotation

Annotation Immunocytochemistry Microscopy Tissue Atlas

Borbala Katona at the microscope

Today, we are back in the Tissue Atlas facilities at the Rudbeck lab in Uppsala. Borbala Katona and Maria Aronsson are research engineers in the group working with microscopy and annotation of stained tissues, which we described last week.

Borbala Katona has a bachelors degree in biomedicine and a masters degree in infectious medicine and has been working within the Human Protein Atlas since 2014.

Maria Aronsson has a masters degree in medical biology from Link÷ping University and joined the Human Protein Atlas in 2012...Read more


Tissue Atlas: production and staining

Antibody Immunocytochemistry Tissue Atlas

Today, we start a "mini-series" about our Tissue Atlas here at the blog. Join us on a tour through the lab, meet some of the people working there, and see some really nice images produced by the scientists.

All the work on our Tissue Atlas is done at our Uppsala site, with Cecilia Lindskog as site director. You can learn all about her in one of our previous blog posts.

First we meet research engineer IngMarie Olsson who is group leader for the Tissue Microarray Production, Immunohistochemistry, and Scanning-group...Read more


Image of the week from the Cancer Atlas

Cancer Atlas Image of the week Immunocytochemistry Lung cancer

Today, it is time for the first image of the week from the Cancer Atlas!

Lung cancer is one of the deadliest and most common forms of human cancer. Different forms of lung cancer exist and non-small cell lung cancer is the most common form. The cancer image this week is selected from such a lung cancer that has been immunohistochemically stained for the proliferation marker Ki-67 (MKI67). Ki-67 is the most commonly used immunohistochemical marker in rutin cancer diagnostics. The Ki-67 antigen is expressed in all cell nuclei that are active in the cell cycle and thus positive staining in a tumor cell population reflects the level of proliferation in that particular cancer...Read more


Cancer biomarkers identified

Biomarkers Breast Cancer Cancer Immunocytochemistry Renal Cell Carcinoma

Gabriela Gremel, involved in both studies on cancer biomarkers

In two recent publications the group of Fredrik PontÚn in Uppsala has identified two very strong, independent biomarkers for the prognostic stratification of breast cancer and renal cell carcinoma.

Renal cell carcinoma is the most common type of cancer affecting the kidney and there is an unmet clinical need for better prognostic and diagnostic tools for it. Diagnosis and subtyping of renal cell carcinoma are achieved through the morphological analysis of tumor sections. The application of immunohistochemistry can reveal important additional clues during the diagnostic work-up...Read more
