Abstract:
BACKGROUND: Appropriate seed cell is important for transplantation in the treatment of cerebrovascular disease and other central nervous system disease.OBJECTIVE: To investigate the capacity of human adipose tissue-derived stromal cells (ADSCs) to differentiate into neurons.METHODS: The fatty tissue was harvested from removed abdominal unnecessary fat of healthy adult with no communicable disease or endocrine disease. Human ADSCs were isolated from human liposuction tissues and cultured in neural induction medium with GM1. Invert phase-contrast microscopy was used to observe morphology changes of ADSCs. The expression of nestin, neuron specific enolase (NSE) and microtubule-associated protein 2 (MAP2) were identified by immunocytochemistry.RESULTS AND CONCLUSION: The majority of cells displayed typical appearance of neuronal-like cells following induction. Following 1 hours of induction, some cells began to express nestin, and NSE and MAP2-positive cells were observed at 5 hours. ADSCs can differentiate into neurons, and the differentiated neurons have the capacity of expressing nestin, NSE and MAP2.
