The treatment of osteoporosis through transplantation of bone marrow stem cells in the experiments performed on rats

Georgian Medical News

Abstract

The aim of our research was to study pathogenetic features of the development of experimental osteoporosis in rats and possibility of correction through stem cells of bone marrow. For modeling of osteoporosis was tested glucocorticoid model. Experiments were conducted on 30 white male laboratory rats of Lewis line weighing 250-300 g. In the first group the experiment of reproduction of glucocorticoid model were performed (15 animals) by daily intraperitoneal injection of hydrocortisone at a dose of 40 mg/kg per day for 3 weeks. In the second group (15 animals) at 90 days after the creation of model of osteoporosis in the tail vain of the rat were injected 50 million cultured bone marrow stem cells. The control group of animals received intraperitoenal saline at the same volume. The maximum period of observation of the animals in both groups was 2 week, 1, 2, 3, 4, 6, months. Pilot studies carried out at this stage have revealed that glucocorticoid model of osteoporosis is an adequate model for studying the mechanism of early development of osteoporosis and assessment of therapeutic effects. Cell therapy using bone marrow stem cells reduces the severity of osteoporosis, increases bone mineral density and increases strength of th...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
