3 INTRODUCTION Neural progenitors (NPs), with the potential to self-renew and differentiate into neurons and glial cells, have been identified from different regions of the developing and adult brain (1-6). NPs can also be derived from human embryonic stem cells (ESCs) and grown in vitro in the presence of mitogen. These in vitro propagated NPs can proliferate in culture while retaining the potency to differentiate into neurons, oligodendrocytes, and glia. In vitro human neural progenitor expansion makes it possible to grow sufficient numbers of NPs for researchers to study basic developmental biology, drug discovery, and preclinical neural transplantation. Figure 1: Expanded human NPs in the monolayer system on day 3 after passage 10. DESIGN OF THE KIT The Human Embryonic Stem Cell-Derived Neural Progenitor (NP) Expansion Starter Panel is a monolayer system designed for in vitro NP expansion in a serum-free environment. The kit contains a specially formulated N-2 Plus Supplement that has been optimized for NP expansion (7). Human Fibroblast Growth Factor basic (FGF basic) and Neuregulin1-1 (NRG1-1) are included to promote the in vitro proliferation of NPs. Bovine Fibronectin, used to coat plates, is also included. The quantity of each component provided in the kit is sufficient to make 500 ml of growth media for cell expansion. This kit also contains mouse anti-human Nestin antibody. Cells propagated using this kit are Nestin-positive (8) and retain their potency to differentiate into neurons, oligodendrocytes, and glia as identified after differentiation induction by staining with antibodies specific to Tuj1, O4, and GFAP, respectively.

4 LIMITATIONS OF THE PROCEDURE FOR LABORATORY RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC PROCEDURES. The safety and efficacy of this product in diagnostic or other clinical uses has not been established. This kit should not be used beyond the expiration date on the kit label. The quality of the neural stem cells and any variations in the procedure can cause variation in the efficiency of cell expansion and/or differentiation. PRECAUTIONS The acute and chronic effects of over-exposure to reagents of this kit are unknown. Safe laboratory procedures should be followed, and protective clothing should be worn when handling kit reagents. The N-2 Plus Supplement contains human transferrin. This transferrin was tested at the donor level using an FDA licensed method and found to be non-reactive for anti-hiv-1/2 and Hepatitis B surface antigen. As no testing can offer complete assurance of freedom from infectious agents, these reagents should be handled as if capable of transmitting infection.
