Brain Image of the week Immunohistochemistry Pituitary gland Tissue Atlas

Today, you will be introduced to the master gland in the body - the pituitary gland.

The pituitary gland plays a crucial role in human physiology, and together with the hypothalamus this highly conserved and elegant system form a link between the nervous and endocrine system, by controlling the functions of the thyroid, adrenal glands, and the gonads, and also regulating growth, lactation, and water preservation.

The pituitary gland, also called hypophysis, consists of two separate lobes with dual embryonic origin; the anterior (adeno) pituitary gland originates from the oral cavity, and the posterior (neural) pituitary gland develops from the neural plate...Read more


World Malaria Day April 25

Malaria Tissue Atlas

SLC4A1 in kidney.

This blog post is in honor of World Malaria Day

When infected mosquitos bite people they transmit parasites that causes malaria. Symptoms of malaria include fever and flu-like illness, and if left untreated the illness will cause anemia (loss of red blood cells) and eventually death.

According to WHO, malaria caused 429 000 deaths in 2015, and 70% of the deaths are children under the age of 5. Luckily, mortality rates are falling, and since 2010 the mortality has dropped with almost 1/3. Early diagnosis and treatment of malaria reduces deaths and prevents transmission. There are antimalaria drugs available, but currently, there is no availabe malaria vaccine...Read more

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 Linköping University and joined the Human Protein Atlas in 2012...Read more


Tissue Atlas: production and staining

2017-03-21
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


Tissue Image of the Month - Hairs and follicles

Follicles Hair Image of the week Tissue Atlas

A hair and hair follicle stained with H&E showing the different layers: a) external root sheath, b) internal root sheath, c) cuticle layer, d) medulla and e) cortex.

Hello everyone!

Tissue Atlas group is pleased to announce the launch of the Tissue Image of the Month. Previously, you have had the joy of experiencing interesting images of cellular organelles and proteins described by the Cell Atlas. Now we also hope that you will follow the blog posts and pictures of stained tissues with the same excitement and curiosity, as we dive into the world of histology, immunohistochemistry, cells and tissues.

First up - hairs and hair follicles.

Hair fibers consist of cells called trichocytes. The fibers vary in size, disposition and color due to factors such as age, sex, ethnicity and region of the body...Read more
