Abstract
Injury or degeneration of the vertebrate central nervous system often disrupts neuronal circuitry that is built by projection neurons during early embryonic life. Repair of neural network through regeneration of these early-born projection neurons in adult life often fails since stem cells residing in the adult brain are generally programmed to give rise to late-born interneurons. Thus, exogenous cells are needed to rebuild the neural circuitry. Nevertheless, cell replacement in the brain remains a challenging goal because of the lack of safe and effective donor cells, as well as difficulty in remodeling the nonneurogenic adult CNS environment. Here I will concentrate on the donor side and discuss how recent advancement in stem cell technology offers hope for transplant therapy, with a focus on the potentials and hurdles of human embryonic stem cells as a sustainable source.
