Abstract

The article highlights the experience of the "Genofund" biobank of the Ott Research Institute of Obstetrics, Gynecology and Reproductology in bioresource collection in modern obstetrics. To create different types of collections, the following different biobanking strategies were formulated for the first time: cross-sectional and longitudinal (dynamic). Definitions are given for these approaches. The most significant advantages and disadvantages of each of them are noted. Examples of pilot studies conducted on the platform of a bioresource collection created using the complex longitudinal biobanking are given. This approach made it possible to demonstrate, using the example of microRNA analysis, the potential of studying the physiological changes during pregnancy at the present stage, as well as the prospects for finding early predictors of pregnancy complications.

What is already known about the subject?

  • Obstetrics research in recent decades has rarely considered the physiology of pregnancy, but has mainly focused on complications.
  • The dynamism of changes during pregnancy over a short-limited period of time makes it impossible to perform a cross-sectional assessment of a pregnant woman's body, and determines the need to implement a novel longitudinal biobanking strategy.

What might this study add?

  • Two fundamentally different strategies for biobanking samples have been formulated as follows: cross-sectional and longitudinal banking.
  • The collection creation using the longitudinal biobanking strategy makes it possible to study the patterns of physiological changes during pregnancy and search for early predictors of pregnancy complications.
