Training the next generation of pluripotent stem cell researchers.

Human pluripotent stem cells (PSCs) have the unique properties of being able to proliferate indefinitely in their undifferentiated state and of being able to differentiate into any somatic cell type. These cells are thus posited to be extremely useful for furthering our understanding of both normal and abnormal human development, providing a human cell preparation that can be used to screen for new reagents or therapeutic agents, and generating large numbers of differentiated cells that can be used for transplantation purposes. PSCs in culture have a specific morphology and they express characteristic surface antigens and nuclear transcription factors; thus, PSC culture is very specific and requires a core skill set for successful propagation of these unique cells.

Stem cell therapies for the lysosomal storage diseases - the quintessential neurodegenerative diseases.

As a novel neurotherapeutic strategy, stem cell transplantation has received considerable attention. However, little focus of this attention has been devoted to the probabilities of success of stem cell therapies for specific neurological disorders. Given the complexities of the cellular organization of the nervous system and the manner in which it is assembled during development, it seems unlikely that a cellular replacement strategy will succeed for any but the simplest of neurological disorders in the near future.
