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.

Third book

Surprisingly, there are 14 years between these books. That's exactly how long Leo Tolstoy felt one cycle of human maturation constitutes. He had an almost intimate idea of dividing life into periods—conditional periods in which, every fourteen years, a person reaches a new level of understanding.

If, putting aside excessive modesty (briefly and strictly for scientific purposes), we apply this logic to ourselves, a curious picture emerges.

Wound-healing Cellgel

The ability to repair is the most important property of the skin that determines the closure of a wound or injury "at all costs". However, healing can be with or without scarring. So what is the secret?
