Variables Of Human Tissue Samples Repositories

Variables Of Human Tissue Samples Repositories

Modern research has made great strides in medical areas like lung disease and cancer. Researchers now need to have access to high-quality specimens such as bodily fluids and tissues. Many organizations now collect, process, and store human tissue to aid researchers in biomedical research. Although guidelines have been created, they are mostly general protocols that do not include all the details required by researchers who are just starting to use human tissue for research.

However, there are so many who do not know much about the human tissue samples process. If you are also one of them who want to know about human tissue samples then visit

Some of the variables of tissue repositories are:

Types of tissue:

Some repositories only provide FFPE block, while others have more options such as fresh, frozen, or fixed specimens. Some repositories only have specimens for breast cancer, while others provide specimens for a broad range of diseases.


The repository must estimate the tissue that the specimens will need since they are taken from local medical facilities. Special arrangements may be required to collect specimens from specific populations in cases where research might require them.


Tissue repositories have the potential to significantly reduce resources because not all offer delivery of tissues, DNA extraction, or RNA culturing, and extensive analysis of specimens.

Other variables:

Other variables that could affect tissue repositories include the labeling of specimens, collection variables and limitations, time between collection and processing specimens, storage of specimens, and records of how they were collected, processed, and stored.
