Hormones Overview
A hormone is a chemical that is made by specialist cells, usually within an endocrine gland, and it is released into the bloodstream to send a message to another part of the body. It is often referred to as a ‘chemical messenger’. Hormones are found in all multicellular organisms and their role is to provide an internal communication system between cells located in distant parts of the body.
In the human body, hormones are used for two types of communication. The first is for communication between two endocrine glands, where one gland releases a hormone which stimulates another target gland to change the levels of hormones that it is releasing. The second is between an endocrine gland and a target organ, for example when the pancreas releases insulin which causes muscle and fat cells to take up glucose from the bloodstream.
Since hormones are released into the bloodstream and can therefore be carried around the entire body, they can perform both of these actions on many different targets. The complex interplay between the glands, hormones and other target organs is referred to as the endocrine system. Hormones affect many physiological activities including growth, metabolism, appetite, puberty and fertility.
Endocrine glands, which are special groups of cells, make hormones. The major endocrine glands are the pituitary, pineal, thymus, thyroid, adrenal glands, and pancreas. In addition, men produce hormones in their testes and women produce them in their ovaries.
Hormones are powerful. It takes only a tiny amount to cause big changes in cells or even your whole body. That is why too much or too little of a certain hormone can be serious. Laboratory tests can measure the hormone levels in your blood, urine, or saliva. Your health care provider may perform these tests if you have symptoms of a hormone disorder. Home pregnancy tests are similar, they test for pregnancy hormones in your urine.

Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens and human bio-fluid collections from cancer (tumor) tissue, cancer serum, cancer plasma cancer PBMC and human tissue samples from most other therapeutic areas and diseases.
Bay Biosciences maintains and manages it’s own bio-repository, human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and from normal healthy donors available in all formats and types. Our biobank procures and stores fully consented, deidentified and institutional review boards (IRB) approved human tissue samples and matched controls.
All our human human tissue collections, human specimens and human bio-fluids are provided with detailed samples associated patient’s clinical data. This critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers and genetic information. Patient’s data is extremely valuable for researchers and is used to help identify new effective treatments (drug discovery & development) in oncology, other therapeutic areas and diseases. This clinical information is critical to demonstrate their impact, monitor the safety of medicines, testing & diagnostics, and generate new knowledge about the causes of disease and illness.
Bay Biosciences banks wide variety of human tissue samples and biological samples including cryogenically preserved -80°C, fresh, fresh frozen tissue samples, tumor tissue samples, FFPE’s, tissue slides, with matching human bio-fluids, whole blood and blood derived products such as serum, plasma and PBMC’s.
Bay Biosciences is a global leader in collecting and providing human tissue samples according to the researchers specified requirements and customized, tailor made collection protocols. Please contact us anytime to discuss your special research projects and customized human tissue sample requirements.
Bay Biosciences provides human tissue samples (human specimens) from diseased and normal healthy donors; including peripheral whole-blood, amniotic fluid, bronchoalveolar lavage fluid (BAL), sputum, pleural effusion, cerebrospinal fluid (CSF), serum (sera), plasma, peripheral blood mononuclear cells (PBMC’s), saliva, Buffy coat, urine, stool samples, aqueous humor, vitreous humor, kidney stones, renal calculi, nephrolithiasis, urolithiasis and other bodily fluids from most diseases including cancer. We can also procure most human bio-specimens and can do special collections and requests of human samples that are difficult to find. All our human tissue samples are procured through IRB approved clinical protocols and procedures.
In addition to the standard processing protocols Bay Biosciences can also provide human plasma, serum, PBMC bio-fluid samples using custom processing protocols, you can buy donor specific sample collections in higher volumes and specified sample aliquoting from us. Bay Biosciences also provides human samples from normal healthy donors, volunteers, for controls and clinical research, contact us Now.
