Research Interests

The leading trend of the group is the creating of scientific bases of cellular biotechnology and the development of new high-tech biomedical technologies of regenerative medicine. The technology of using of the cultivated cells of human skin (keratinocytes and fibroblasts) for restore of the different etiology wounds was developed.

A number of cell products were created:

  • Dermal equivalent is based on the collagen Type I (collagen gel with the fibroblasts);
  • Dermal equivalent is based on the human plasma fibrin (fibrin gel with the fibroblasts);
  • Multilayer sheet of the keratinocytes;
  • Multilayer skin equivalent (the first layer is the collagen gel containing dermal fibroblasts and second layer is the sheet of the keratinocytes)

The permission of the Ministry of Health of the Russian Federation for serial production and clinical application of the dermal equivalent is based on the collagen Type I and the multilayered sheet of the keratinocytes have been received.

The cell products have been tested on clinical practice for the healing wounds of different etiology: burns, venous and diabetic ulcers, fistula (Crohn's disease, gunshot wounds), bedsores etc. They were applied into the leading clinics of the Saint-Petersburg: Saint-Petersburg I.I. Gzhanelidze Research Institute of Emergency Medicine, S.M. Kirov Army Medical Academy, Saint-Petersburg Hospital for Veterans of War, Saint-Petersburg Hospital ╣9 and other hospitals.
Dermal fibroblasts were cultured on the porous polytetrafluoroethylene membrane with a positive result have been used in ophthalmology for scleroplasty (Saint-Petersburg Hospital ╣2).

Nowadays the experimental possibilities of using the bone marrow stromal cells cultured on the biodegradable 3D scaffolds to restore the damage of the bladder and the application of the limbal cells to restore the cornea are investigated.
The one of the direction of the investigations is the research of the inducted differentiation of the bone marrow stromal cells into osteogenic and chondrogenic directions in order to use them for regeneration of bone and cartilage tissues.
Another direction of our works is the isolation from different tissue the extracellular proteins such as collagen of various types, laminin, fibronectin and other once for research and clinical applications.

Traditional methods of cell biology including isolation of cells from different tissues of human and animals, cultivation of normal, immortalized and cancer cells into the 2D and 3D conditions, analysis structure and properties of 3D scaffolds, confocal immunoflurescence.
