Abstract:
The differentiation efficiency of 3T3-L1 preadipocytes is an essential factor affecting studies on cellular mechanisms associated with obesity, diabetes, and related disorders. Differentiation of 3T3-L1 cells is commonly induced by an adipogenic cocktail containing insulin, dexamethasone (DEX), and 3-isobutyl-1-methylxanthine (IBMX). However, 3T3-L1 cells after freezing and thawing for many times always have a low differentiation efficiency. To solve this problem, we compared the differentiation efficiency of six commonly used adipogenic cocktails and protocols published in 2017. On this basis, we further compared 18 adipogenic cocktails with 2 μM rosiglitazone added and/or with a prolonged treatment with IBMX. The results revealed that the adipogenic cocktail containing 0.5 mM IBMX, 1 μM DEX, and 10 μg/mL insulin was the most effective for the frozen-thawed 3T3-L1 cells differentiation. Rosiglitazone, and IBMX under a prolonged treatment, could improve the differentiation efficiency of the frozen-thawed 3T3-L1 cells. However, the effect was closely related to concentrations of agents in the adipogenic cocktails.

Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...
Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
