Our recent in vitro study demonstrated that endothelial cells (ECs) might influence the differentiation of bone marrow stromal cells (BMSCs). Therefore, the aim of this study was to describe this effect in vivo, using a rat calvarial bone defect model. BMSCs were isolated from femurs of two-donor Lewis rats and expanded in α-minimum essential medium containing 10% fetal bovine serum.

- High-fluoride drinking water poses health risks, especially in the East African Rift Valley, prompting a project to find a simple removal method.
- 22 soil samples from central Ethiopia were tested for their ability to reduce fluoride from water using NaF solutions over 30 days.
- Results showed significant variations in fluoride removal, with some soils decreasing fluoride concentration by up to 98.5% after 30 days, and only small amounts leaching back into the water.
- The study suggests that lateritic soils could effectively reduce fluoride levels, recommending further tests for household use.
