Study of lead-induced neurotoxicity in cholinergic cells differentiated from bone marrow-derived mesenchymal stem cells.

The developing brain is susceptible to the neurotoxic effects of lead. Exposure to lead has main effects on the cholinergic system and causes reduction of cholinergic neuron function during brain development. Disruption of the cholinergic system by chemicals, which play important roles during brain development, causes of neurodevelopmental toxicity.

Study of the chlorpyrifos neurotoxicity using neural differentiation of adipose tissue-derived stem cells.

Chlorpyrifos (CPF) is the most commonly used organophosphorus insecticide which causes neurodevelopmental toxicity. So far, animals have been used as ideal models for neurotoxicity studies, but working with animals is very expensive, laborious, and ethically challenging. This has encouraged researchers to seek alternatives.

Study of lead-induced neurotoxicity in neural cells differentiated from adipose tissue-derived stem cells.

In recent years, the use of stem cells as a new tool to create an in vitro model for toxicological studies has been considered. Adipose tissue-derived stem cells (ADSCs) are mesenchymal stem cells which have been extracted from adipose tissue by a less invasive method and rapidly propagated in culture medium compared with other sources. These cells have the capacity to differentiate into different cell lineage in vitro including neural cells.
