The signals that prompt the axons to send out processes in peripheral nerves after axotomy are not well understood. Here, we report that galectin-1 can play an important role in this initial stage. We developed an in vitro nerve regeneration model that allows us to monitor the initial axon and support cell outgrowth from the proximal nerve stump, which is… (More)
RNA has been proposed to be a component of an underlying nuclear matrix. Hall et al. show that noncoding, repetitive RNAs, some derived from LINE1 elements, stably associate with interphase chromosomes and copurify with nuclear scaffold, indicating that RNAs might impact interphase chromosome architecture.
