BACKGROUND AND AIMS: Tissue engineering strategy has been considered as an alternative treatment for diabetes mellitus due to lack of permanent pharmaceutical treatment and islet donors for transplantation. Various cell lines have been used to generate functional insulin-producing cells (IPCs) including progenitor pancreatic cell lines, embryonic stem cells (ESCs), umbilical cord blood stem cells (UCB-SCs), adult bone marrow stem cells (BMSCs), and adipose tissue-derived stem cells (ADSCs).
METHODS: Human ADSCs from lipoaspirated abdominal fat tissue was differentiated into IPCs following a two-step induction protocol based on a combination of alternating high and low glucose, nicotinamide, activin A and glucagon-like peptide 1 (GLP-1) for a duration of 3 weeks. During differentiation, histomorphological changes of the stem cells towards pancreatic β-islet characteristics were observed via light microscope and transmission electron microscope (TEM). Dithizone (DTZ) staining, which is selective towards IPCs, was used to stain the new islet-like cells. Production of insulin hormone by the cells was analyzed via enzyme-linked immunosorbent assay (ELISA), whereas its hormonal regulation was tested via a glucose challenge test.
RESULTS: Histomorphological changes of the differentiated cells were noted to resemble pancreatic β-cells, whereas DTZ staining positively stained the cells. The differentiated cells significantly produced human insulin as compared to the undifferentiated ADSCs, and its production was increased with an increase of glucose concentration in the culture medium.
CONCLUSIONS: These initial data indicate that human lipoaspirated ADSCs have the potential to differentiate into functional IPCs, and could be used as a therapy to treat diabetes mellitus in the future.

As indicated by the World Health Organization as of year 2014, around 10,000 people have been influenced with Ebola infection. The episode of Ebola in African locale is courged with a high death rate. Notwithstanding, in the United States, people influenced by Ebola have been given brilliant wellbeing offices, as the U.S. is one of the highest nations that have taken sterner wellbeing measures and principles against Ebola. Aside from the U.S., individuals in Asia, where billions live in indigence and general wellbeing frameworks are frequently extremely powerless, are under more serious danger of the Ebola infection. Despite the fact that nations like Singapore, Malaysia, South Korea and Japan can take stretched out measures to battle against the infection, nations like Philippines and Indonesia have unfathomable quantities of poor who may be incredibly influenced by a conceivable episode. At this moment, the chances that Asia will take a critical hit from the Ebola infection appear to be genuinely little. Yet, while it is far-fetched that Asia will encounter a real flare-up, genuine concerns stay about the infection coming to urban communities like Hong Kong, Beijing, Shanghai and Singapore through their worldwide airplane terminals. Wellbeing priests from the Association of Southeast Asian Nations (ASEAN) reported key measures not long ago to keep the Ebola plague from coming to the locale and to backing influenced nations. This article accordingly will concentrate on the prevalence and current approaches of Ebola Virus Disease in ASEAN nations which is the need of the hour.
