This paper carried out experimental study, through extraction and characterization of both crude and refined castor oil. Normal hexane was used as solvent for the extraction process. The oil produced was refined through degumming, neutralization and bleaching process using local adsorbent (activated clay). The characterization analysis revealed that tested parameters, which include specific gra...

BACKGROUND Liver steatosis was caused by lipid accumulation in the liver. Alisma orientale (AO) is recognized as a promising candidate with therapeutic efficacy for the treatment of nonalcoholic fatty liver disease (NAFLD). HepG2 hepatocyte cell line is commonly used for liver disease cell model. METHOD The HepG2 cells were cultured with the NEFAs mixture (oleic and palmitic acids, 2:1 ratio)...

Adipose-derived stromal/stem cells (ASCs) are adult stem cells that have the potential to differentiate into mesenchymal lineage cells. The abundance of ASCs in adipose tissue and easy accessibility with relatively little donor site morbidity make them attractive candidate cells for tissue engineering and regenerative medicine. However, the underlying inflammatory process that occurs during ASC...

We report the effects of two-dimensional graphene nanostructures; graphene nano-onions (GNOs), graphene oxide nanoribbons (GONRs), and graphene oxide nanoplatelets (GONPs) on viability, and differentiation of human mesenchymal stem cells (MSCs). Cytotoxicity of GNOs, GONRs, and GONPs dispersed in distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)] (DSPE-PEG), on adipose d...

LIGHT (HVEM-L, TNFSF14, or CD258), an entity homologous to lymphotoxins, with inducible nature and the ability to compete with herpes simplex virus glycoprotein D for herpes virus entry mediator (HVEM)/tumor necrosis factor (TNF)-related 2, is a member of the TNF superfamily. It is expressed as a homotrimer on activated T cells and dendritic cells (DCs), and has three receptors: HVEM, LT-β rece...

Objective: To compare the characteristics of human gingival fibroblasts (hGFs) obtained by tissue-explant and enzyme-digestion methods. Methods: The hGFs were isolated using tissue explants and enzyme digestion methods and identified by immunocytochemical analysis. Cell-surface molecules were detected by flow cytometry analysis. The colony-forming activity was examined by CFU-F assay. Oil red O...

Human mesenchymal stem cells (hMSCs) are highly desirable cells for bone engineering due to the inherent multipotent nature of the cells. Unfortunately, there is a high degree of variability, as primary hMSC cultures quickly undergo replicative senescence with loss of proliferative potential as they are continually propagated in cell culture. We sought to reduce the variability of these cells b...

Osteoporosis poses a major public health threat in aging societies. Adipose-derived stem cells (ADSCs) are multipotent adult stem cells that have the ability to yield mesenchymal stem cells, and have the potential to undergo osteogenesis and bone regeneration. Bone morphogenetic proteins (BMPs) have been demonstrated to upregulate bone gene expression after mechanical injury and to improve bone...

A new vibrational imaging method based on coherent anti-Stokes Raman scattering (CARS) has been used for high-speed, selective imaging of neutral lipid droplets (LDs) in unstained live fibroblast cells. LDs have a high density of C-H bonds and show a high contrast in laser-scanning CARS images taken at 2,845 cm-1, the frequency for aliphatic C-H vibrations. The contrast from LDs was confirmed b...

BACKGROUND Mesenchymal stem cells (MSCs) from different sources have different characteristics. Moreover, MSCs are not isolated and characterized in Guinea pig for animal model of cell therapy. AIM OF THE WORK was the isolating of bone marrow MSCs (BM-MSCs) and adipose tissue MSCs (AT-MSCs) from Guinea pig and assessing their characteristics. MATERIAL AND METHODS In this study, bone marrow ...
