The major cell classes of the brain differ in their developmental processes, metabolism, signaling, and function. To better understand the functions and interactions of the cell types that comprise these classes, we acutely purified representative populations of neurons, astrocytes, oligodendrocyte precursor cells, newly formed oligodendrocytes, myelinating(More)
To investigate the role of microRNAs in regulating oligodendrocyte (OL) differentiation and myelination, we utilized transgenic mice in which microRNA processing was disrupted in OL precursor cells (OPCs) and OLs by targeted deletion of Dicer1. We found that inhibition of OPC-OL miRNA processing disrupts normal CNS myelination and that OPCs lacking mature(More)
The kinesin motor protein Kif1b has previously been implicated in the axonal transport of mitochondria and synaptic vesicles. More recently, KIF1B has been associated with susceptibility to multiple sclerosis (MS). Here we show that Kif1b is required for the localization of mbp (myelin basic protein) mRNA to processes of myelinating oligodendrocytes in(More)
Melanoma is the most dangerous form of skin cancer occurring in Caucasians with rising incidence. They are remarkably resistant to conventional anti-tumour therapies like chemotherapy and radiotherapy. Therefore, new treatment strategies are urgently needed. Anti-tumour effects of phytochemicals such as allyl isothiocyanate or cinnamaldehyde have been(More)
We present SynFlo, a tangible museum exhibit for exploring bio-design. SynFlo utilizes active and concrete tangible tokens to allow visitors to experience a playful biodesign activity through complex interactivity with digital biological creations. We developed two versions of SynFlo: one that combines active tokens with real concrete objects (i.e. labware)(More)
We present BacPack for New Frontiers, an interactive museum exhibit that introduces core synthetic biology concepts to visitors through tangible, multi-touch, and physical interaction. The exhibit engages users in the design and engineering of bacteria, which are helpful in extreme environments like Mars. This project aims to allow museum visitors to play(More)
This protocol describes the generation of a rapidly myelinating central nervous system coculture for the study of complex neuronal-glial interactions in vitro. Postnatal rat retinal ganglion cells (RGCs) purified by immunopanning are promoted to cluster into reaggregates and then allowed to extend dense beds of radial axons for 10-14 d. Subsequently, rodent(More)
Astrocytes constitute a major cell population in the brain with a myriad of essential functions, yet we know remarkably little about the signaling pathways and mechanisms that direct astrocyte maturation. To explore the signals regulating astrocyte development, we prospectively purified and cultured immature postnatal rodent astrocytes. We identified(More)
In this article, we introduce methods for generating rapidly myelinating cocultures with reaggregates of purified retinal ganglion cells and optic nerve oligodendrocyte precursor cells. This coculture system facilitates the study of complex central nervous system neuronal-glial interactions and myelination. It enables control of the extracellular(More)
