The data of the healing of the acute ulcers of the legs by the substitutive cell therapy method are presented. The cell products (the skin derm and epidermis equivalents) were prepared by using of the cultivated of normal human keratinocytes and fibroblasts. The life of the ulcer defects of the patients was up 5 months to 4 years. The process of a total epithelisation of an ulcer in 14-22 days of 40 patients took place 19 patients; a decrease in size of the ulcer to 70-80 % were observed with another 19 patients; the ulcers of 2 patients were not changed. The analysis of the obtained results demonstrates about the perspective of the proposed method of the healing of the acute ulcers.

OF THE HUMAN EMBRYONIC STEM CELL LINES RECEIVED ON THE BASE OF CELL CULTURE COLLECTION
Long-term cultivation of human blastocyst-derived embryonic cells (hES) was performed. Several properties of hESs were examined to prove the state of continuous cell lines. These cells passed more 200 population doublings with the average population doubling time of 37.0+1.5h. The isolated hESs refered to as HESC-1, HESC-2, HESC-3, HESC-4, cultivated on mitotically inactivated mouse embrionic fibroblasts (STO continuous cell line) formed multilayer colonies of various shape. The cells maintained stable proliferative activity, high activity of alkaline phosphatase and expression of transcription factor Oct4 which are characteristics of embryonic stem cells of different origin. Expression of hES specific cell surface antigenes (SSEA-3, SSEA-4, TRA-1-81 and TRA-1-60) was confirmed by immunofluorescence analysis with the corresponding monoclonal antibodies. An additional proves for species specificity of HESC lines is the lack of expression of mouse specific surface antigene SSEA1.

We have established a number of human embryonic cell lines from blastocysts unacceptable for further use. Mouse feeder cells were used for cell lines establishment and propagation. Derived cell lines were characterized on the embryonic stem cells immuno markers, alkaline phosphatase, and telomerase activity. All cell lines demonstrated normal caryotype. At present all derived cell lines underwent more than 150 doublings.

Usage of genes - activators of transcription as a new
perspective approach in sea biotechnology.
N.A. Odintsova, S.V. Plotnikov, K.V. Kiselev, V.P. Bulgakov.
Many problems of biotechnology cannot be solved without continuous cell lines from marine invertebrates. Primary cell cultures from sea urchins have a low proliferative level that prevents the establishment of their long-term cultures. To increase expression levels of the cell growth regulatory genes of sea urchins and thus achieve enhanced cell growth, we used the transcriptional activator Gal4 gene, found earlier in yeast. Sea urchin embryos as well as embryo-derived cells were transformed with the Gal4 gene. This treatment was shown to result in formation of teratoma-like structures possessing neoplastic features and enhanced cell growth potential. After 2-month-cultivation, some pigments were found in cultivated cells from transfected embryos. The absorbtion spectrum of these pigments was similar to that of a echinochrom - biological active substance of a great therapeutic potential.

Cytological and histological analysis of developing androclynic morphogenic and non-morphogenic calli obtained in anther culture of wheat, was performed. The detailed light- and electron microscopy reveal sufficient difference between the morphogenic and non-morphogenic calli. The morphological variability of cells of morphogenic callus was established. The cells of certain zones of morphogenic callus are characterized as meristematic. The main peculiarities of the non-morphogenic callus are the absence of the meristematic character and gradual degradation of its cells.
proliferation induced by anti-DNA antibodies. D.A. Temnikov, Ò.À. Nevzorova, V.G.
The ability of pathogenic anti-DNA antibodies (Abs) in autoimmune diseases (systemic lupus erythematosus, SLE) to penetrate into the cells has already been proved. These antibodies can cause functional changes in the cells. Some antibodies can bind to the cell surface and lead to its lysis. Other pathogenic Abs penetrate into the cell and bind with cytoplasmic or nuclear structures. However, the problem of how Abs affect cells still remains open.
In the present paper we carried out a comparative research of kidney cells proliferation in the presence of anti-DNA antibodies. The Abs were extracted from different sources: the SLE patients serum before and after prednisolone (the main drug in SLE therapy) treatment, and the donors’ serum. Several fractions of Abs were obtained from each serum, that differ in the anion-exchange cellulose binding. In the SLE serum we found the Abs fraction that can stimulate cell growth. Moreover, the short-term hormonal treatment resulted in the loss of this stimulating capability.
We suppose that Abs are one of the main organisms factors that cause proliferation of epithelial tissue in glomerulonephritis. Possible mechanisms of this influence are discussed.

On the question of xenotransplantation of culture from cells and tissues of endocrine organs.
I.S. Turchyn, I.I.
A new method for the treatment of endocrine disorders by transplantation of corresponding cell and organ cultures was developed. The biological properties of these cultures and their abilities for proliferation were studied and hormonal production were shown. They had an adequate reaction to tropic hormones of the pituitary. The methods of isolation and cultivation of cell and tissue cultures from the thyroid, parathyroid, adrenal glands, testes, pancreatic islands of human fetuses and newborn pigs were developed. The method prospects for clinical practice were revealed by the transplantation of corresponding cell and tissue cultures in diabetes mellitus, hypocorticoidism, hypothyroidism and hypogonadism.

Ability of rat smooth muscle cell seeding on porcine aorta wall fragments aimed to reduce their calcification after implantation in rats was studied. The calcium deposits in aorta wall fragments seeded by the cells were shown to be significantly smaller with respect to unseeded fragments. The results obtained point to the efficiancy of seeding a heart valve transplant by smooth muscle cells taken from a recipient to suppress tissue calcification after the implantation.

Basic features of human satellite muscle cells (SMC) isolation and mass cultivation were reviewed in this paper. The possibility of using myoblasts derived from SMC cultures of healthy donors for cell mediated therapy of Duchenne myodystrophy was also discussed. It was shown that sequentiall treatment of muscle tissue with Versen solution, then 0,1% trypsin solution and then 0,1% collagenase solution is a perfect way to isolate SMC from muscle tissue. This allows to get a material, that contains about 80-90% of SMC cells. The efficiency of this approach is about 300 000 SMC cells per 0,5 g of muscle tissue weight. The isolated SMC cells can be stored in liquid nitrogen without significantly loss of viability, if the cells were frozen immediately after isolation in F12 culture media with 20% embryonal calf serum and 10% DMSO. Cultivation of SMC in F12 culture media with some additions (epidermal growth factor, insulin, dexametazon, fetuin) provide a higherst intensity of cells proliferation. On the other hand, the DMEM culture media with addition of 2% embryonal calf serum induced differentiation of SMC into myoblasts most effectively for this. The content of carbon dioxide in air should be lower than 5%. The described approaches of cultivation provides an increase of proliferation potential of muscle cells up to 40-45 passages. It is enough to producing of biomass that consists of several billions of cells. The muscle cells obtained from healthy donors were used for a cell mediated therapy of Duchenne myodystrophy. In general possibility of this therapeutic approach was shown, but it is inefficient for practical use. Some problems connected to the effectivity of cell mediated therapy were discussed in this paper. One of these problems is that the cell substitutional therapy requires immortal cells. The hTERT transfected muscle cells have telomerase activity but it does not lead to immortalization of the cells.

ZYMOGRAPHY - A FAST AND RATHER CHEAP METHOD OF DETECTING OF PROTEASES IN DIFFERENT BIOLOGICAL FLUIDS. I.V. Voronkina
Zymography is a quantitative and qualitative method of detecting proteases in different biological fluids - tissue extracts, wound fluids or conditioned cells mediums. The use of certain macromolecular proteins co-polymerized into electrophoresis gels allows fast and cheap detecting presence and activity of different proteases. With help of the zymography estimating protease activity and molecular weight could be done simultaneously. This paper discribes different modifications of the zymography assay for detecting various types of proteases and protease inhibitors. An example of the standard process of the gelatin zymography is given.
