Bioresource collections: algorithms for development and functioning; basic and applied significance

Abstract

Bioresource collection of the N. N. Blokhin National Medical Research Center of Oncology is a unique structured biobank that combines different types of primary and subsidiary samples and ensures its comprehensive characterization, including both generally accepted indicators and specific types of research. Samples of paraffin blocks, frozen material, blood and its derivatives are deposited in the clinical department of the center. The research institute of the center has collected commercial and unique human cell lines and transplantable strains obtained from clinical material, as well as cells from laboratory animals, mainly of mouse origin. The provided cell lines undergo multi- stage quality control, including confirmation of authenticity, assessment of viability and determination of optimal cultivation conditions, analysis of interspecific and intraspecific contamination, study of tumorigenicity and reproducibility in athymic Balb/ c-nude mice, etc. In addition, the Bioresource Collection has hybridoma clones that produce antibodies to a wide range of targets. The Center provides the opportunity to conduct preclinical research using samples from the Bioresource Collection to obtain scientific and regulatory data on the antiproliferative activity of new agents or methods for cancer treatment.
