METHOD OF PROVIDING SAFETY OF APPLICATION OF PLURIPOTENT STEM CELLS IN TISSUE-SUBSTITUTING THERAPY BY MEANS OF ARTIFICIAL CHROMOSOMES Russian patent published in 2015 - IPC C12N15/02 C12N15/09 C12N15/87 C12N5/07 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, genetic engineering and biotechnology. Claimed is method of providing tumour-free tissue-substituting therapy on the basis of obtained from adult somatic cells induced pluripotent stem cells (iPSC), where the latter are genetically modified by means of artificial chromosome (AC), carrying bicistronic cassette with suicide-gene and gene of sensitivity to antibiotic under control of regulatory element, specific for pluripotent stem cells, with modified iPSC being selected in presence of respective antibiotic, absence of AC integration into iPSC genome is confirmed, are introduced into recipient organism directly, without preliminarily differentiation in vitro, after 1-14 days patients are given a 5-10-day course of therapy with inductor of toxicity of suicide-gene product.

EFFECT: invention makes it possible to reduce to zero risk of cancer transformation of transplanted cells and development of teratomas, increase clinical efficiency of recovery of cell mass of injured organ or tissue, reduce waiting time for potential recipients.
