Repair mechanism of mesenchymal stem cells derived from nasal mucosa in orbital fracture

Abstract

Mesenchymal stem cells (MSCs) derived from nasal mucosa are featured by high division and differentiation capacity, with large nuclei, obvious nucleoli and weak cytoplasmic basophily. Imaging examination, typically CT scan, is the gold standard for the diagnosis of orbital fracture. We isolated MSCs derived from goat nasal mucosa and built the calcification model so as to investigate the repair mechanism of nasal mucosa-derived MSCs in orbital fracture. Expressions of osteogenic markers Runx2, OCN, OPN and BSP were detected using western blot. Nasal mucosa-derived MSCs were successfully isolated and passaged. Nestin was detected by immunofluorescence assay in the cells of the third generation. It was further confirmed that the isolated cells were nasal mucosa-derived MSCs. As indicated by alizarin red staining, the calcification model in nasal mucosa-derived MSCs was successfully built. The relative expressions of Runx2 and OCN reached the highest level after osteogenic induction for 7 d, and the expressions of OPN and BSP were also high. But at 10 d, the expressions of all markers declined somewhat. At 14 d, the expressions of OPN and BSP reached the peak, but without significant differences compared with those at 7 d. The pre...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.
