METHOD FOR DETERMINING SUBPOPULATION COMPOSITION OF SKIN CELLS AND OBTAINING SKIN CYTOIMMUNOGRAM

FIELD: medicine.

SUBSTANCE: method for determining the subpopulation composition of skin cells and obtaining the skin cytoimmunogram comprises sampling a skin biopsy specimen to a depth of 2 mm, homogenizing the tissue in a 0.9% aqueous solution of sodium chloride at a temperature of +23…+25°C, extracting the homogenate, filtering the homogenate through an inert filtering partition with a pore diametre of 20 mcm, centrifuging the homogenate at 400 g for 5 minutes at a temperature +23…+25°C. After centrifugation, the viability of the skin cells is determined, the skin cells are incubated for 20 minutes with monoclonal antibodies fluorochrome-labeled for flow cytometry, phenotyping of the skin cells is carried out, the number of skin cells of a specific phenotype - skin cytoimmunogram - are determined: keratinocytes CD49f+, among them activated CD49f+HLA-DR+; fibroblasts (fibrocytes) CD45-CD14-CD44+, among them activated CD45-CD14-CD44+CD80+; mast cells CD249+, among them activated CD249+CD63+; monocytes (macrophages) CD45+CD14+, among them activated CD45+CD14+HLA-DR+; intra-epidermal macrophages CD207+, among them activated CD207+CD80+, CD207+HLA-DR+, CD207+CD80+HLA-DR+; endothelial cells CD146+, among them activated CD146+CD34+, CD146+HLA-DR+, CD146+CD54+, CD146+CD54+HLA-DR+; lymphocyte populations: T-lymphocytes CD45+CD3+, T-helpers CD45+CD3+CD4+CD8-, T-suppressors CD45+CD3+CD4-CD8+, B-lymphocytes CD45+CD3-CD19+, NK-lymphocytes CD45+CD3-CD16+CD56+.

EFFECT: application of this method allows to make a quantitative and functional characteristic of all the skin constituent elements for use in diagnosis.

Masks. Part two: faces of time.

Even to the horrors of war, the doctor gets used to much faster than an ordinary person, as well as soldiers, after two or three weeks already much without noticing and assessing what is happening, as a matter of course. What can we say about the events taking place during the expedition, when the phenomenon recorded by the photo may contain a different depth of meaning, often understood only after some time. The expedition Live Parallel, organized by Professor A. G. Teslinov in Peru and Bolivia and ended 2 months ago, was not an exception for me. Read more...

Дорога кончилась, началось направление...

Действительно, когда кончается дорога - символ благоустройства, основа порядка градостроения, обязательный элемент в системе современных отношений, то начинается... направление - символ свободы выбора. Помните, в фильме «Кин-дза-дза»:
– Будем считать, что Ашхабад там!

Comparative evaluation of quality of hematopoietic stem cells of umbilical cord blood at various methods of cryopreservation
Comparative evaluation of quality of hematopoietic stem cells of umbilical cord blood at various methods of cryopreservation

Studied the proliferative potential and viability of hematopoietic stem cells (HSC) cord blood (PB), depending on the method of cryopreservation. Cryopreservation of samples was carried out in software Planer freezer and liquid nitrogen vapor. Found that, for cryopreservation of samples GSK PC software should be used freezer, since this method of preservation of the cells remain vi- able and functional completeness.
