Immature hematopoietic progenitors are a constant source for renewal of hemocyte populations and the basic component of the tissue and cell repair apparatus. A unique property of these cells of internalizing extracellular double-stranded DNA has been previously shown. The leukostimulatory effect demonstrated in our pioneering studies was considered to be due to the feature of this cell.

A fundamentally new biotechnological approach has been applied to the delivery of genetic material into eukaryotic stem and progenitor cells by establishing an artificial "recombinogenic situation" in them to induce homologous recombination (equivalent replacement) of mutant DNA regions with healthy hDNA. In experimental preclinical trials, the effectiveness of genomic balancing technology has been proven to reduce the risk of sudden death in old animals and to increase the lifespan of outbred mice by 30% and Wistar rats by 57%.

The study included five groups. The subpopulations of the hematopoietic stem cells were studied in 569 samples of the mobilized peripheral blood mononuclear cells from adult cancer cases (group 1), 557 samples from children cancer cases (group 2), 66 samples from amyotrophic lateral sclerosis cases (group 3), 5 samples from other neurodegenerative diseases cases (supplementary group 4) and 61 samples isolated from healthy donors (control group 5).

The theory posits the hypothesis that the higher nervous activity (cognitive, intellectual, mnestic) of the humans and their mind are material and have microwave electromagnetic nature. The theory perceives the human mind as a result of dynamic extracortical information-commutation relations of the super-positions of the electromagnetic waves of ultra high frequency emitted by different areas of the human brain in the inter-membrane cerebrospinal fluid space of the human head at a certain period of time.

GBM aggressive nature is associated with a special phenotype of cancer cells that develops because of the transforming growth factor β (TGF-β).

Its invasive growth is associated with cluster of differentiation (CD)133 cancer stem cells (CSCs) and CD133 differentiated glioblastoma cells (DGCs) with aggressive phenotype, which are developed under the influence of transforming growth factor (TGF)-β. The present study aimed to compare the proteomes of CD133 CSCs and CD133 DGCs stimulated by TGF-β, as well as the expression levels of the main proteins responsible for activating the signaling pathway of receptor interactions with the extracellular matrix (ECM).

The prognosis for GBM patients is not favorable, with the median survival time being 15 months. Its treatment resistance is associated with GBM cell population having cancer stem cells (CSCs).

It is characterized by invasive growth and strong resistance to treatment, and the median survival time of patients is 15 months. The invasive growth of this tumor type is associated with tumor cells with an aggressive phenotype, while its treatment resistance is attributed to cancer stem cells (CSCs).

Virchow in 1863 was the first German pathologist using histomorphological techniques discovered that GBM is a tumor of glial origin. Virchow (1863/65) also then used the term Glioma for the first time and classified as low-grade glioma and high-grade glioma very similar to that of today according to World health organization (WHO) classification (Jellinger, 1978; Virchow, 1863/65).

Methods: Primary CRC patients, who were initially diagnosed between 2010 and 2015 in the SEER database, were included to analyze BM incidence and risk factors for BM occurrence. The patients with at least 1-year follow-up were involved to investigate the prognostic factors for BM.
Based on a large-population analysis, we aimed to estimate the incidence and survival of bone metastases (BM) in initial bladder cancer (BC) patients and to identify the risk and prognostic factors of BC patients with BM. Using the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database, bladder cancer patients diagnosed between 2010 and 2014 were retrieved. Multivariate logistic and Cox regression analyses were employed to identify risk factors and prognostic factors for BM in BC patients.

Cell therapy has been shown to be a key clinical therapeutic option for central nervous system diseases or damage. Standardization of clinical cell therapy procedures is an important task for professional associations devoted to cell therapy. The Chinese Branch of the International Association of Neurorestoratology (IANR) completed the first set of guidelines governing the clinical application of neurorestoration in 2011.

A primary reason for its resistance to treatment is associated with cancer stem cells (CSCs), of which there are currently no effective ways to destroy. It remains unclear what cancer cells become a target of stem cell migration, what the role of this process is in oncogenesis and what stem cell lines should be used in developing antitumor technologies.

Aim: To evaluate the short and long-term effects of the complex cell therapy of 202 cases of spinal cord injury (SCI).
Methods: The main arm included 202 cases of SCI and the control arm included 20 SCI cases. For the therapy the hematopoietic stem cells (HSCs) and progenitor cells (PCs) were mobilized to peripheral blood by 8 subcutaneous injections of granulocyte colony-stimulating factor (G-CSF) for 4 d and are harvested at day 5.
Multiform glioblastoma is the most common primary, highly invasive, malignant tumor of the central nervous system, with an extremely poor prognosis. The median survival of patients following surgical resection, radiation therapy and chemotherapy does not exceed 12-15 months and thus, novel approaches for the treatment of the disease are required. The phenomenon of the directed migration of stem cells in tumor tissue presents a novel approach for the development of technologies that facilitate the targeted delivery of drugs and other therapeutic agents to the tumor foci.
