Project description:To examine the cellular heterogeneity in the PF, in mouse, we used droplet-based single cell RNA sequencing technique developed by Klein et al. 2015, Cell 161, 1187–1201. doi:10.1016/j.cell.2015.04.044.

Project description:Nuclei of the mammalian thalamus are aggregations of neurons with unique architectures and input-output connections, yet the molecular determinants of their organizational specificity remain unknown. By comparing expression profiles of thalamus and cerebral cortex in adult rhesus monkeys we identified transcripts that are unique to dorsal thalamus or to individual nuclei within it. Real-time quantitative polymerase chain reaction and in situ hybridization analyses confirmed the findings. Expression profiling of individual nuclei microdissected from the dorsal thalamus revealed additional subsets of nucleus-specific genes. Functional annotation using Gene Ontology (GO) vocabulary and Ingenuity Pathway analysis revealed over-representation of GO categories related to development, morphogenesis, cell-cell interactions, and extracellular matrix within the thalamus- and nucleus-specific genes-many involved in the Wnt signaling pathway. Examples included the transcription factor TCF7L2, localized exclusively to excitatory neurons, a calmodulin-binding protein PCP4, the bone extracellular matrix molecules SPP1 and SPARC, and other genes involved in axon outgrowth and cell matrix interactions. Other nucleus-specific genes such as CBLN1 are involved in synaptogenesis. The genes identified likely underlie nuclear specification, cell phenotype and connectivity during development and their maintenance in the adult thalamus. Keywords: brain region comparative analysis

Project description:The paraventricular nucleus of the thalamus (PVT) is known to regulate various cognitive and behavioral processes. However, while functional diversity among PVT circuits has often been linked to cellular differences, the molecular identity and spatial distribution of PVT cell types remains unclear. To address this gap, here we used single nucleus RNA sequencing (snRNA-seq) and identified five molecularly distinct PVT neuronal subtypes. Additionally, multiplex fluorescent in situ hybridization of top marker genes revealed that PVT subtypes are organized by a combination of previously unidentified molecular gradients. Lastly, comparing our dataset with a recently published single-cell sequencing atlas of thalamus yielded novel insight into the PVT’s connectivity with cortex, including unexpected innervation of auditory and visual areas. This comparison also revealed that our data contains a largely non-overlapping transcriptomic map of multiple midline thalamic nuclei. Collectively, our findings uncover previously unknown features of the molecular diversity and anatomical organization of the PVT and provide a valuable resource for future investigations.

Experiment Overall Design: To determine the molecular underpinnings of nuclear specificity in the dorsal thalamus we isolated micro-punches of tissue from nucleus-specific regions and processed them for microarray analysis. Replicate samples from 5 separate dorsal thalamic nuclei were processed and compared to identify genes unique to each region. Affymetrix U133A Gene Chips were used. All of the samples were isolated from untreated adult monkey brain.

Project description:Knowledge of the full repertoire of thalamus cells and their gene expression profiles is a fundamental first step in this endeavor. Here, using single-nuclei RNA sequencing (snRNA-seq), we sequenced the transcriptomes of 32332 single brain cells, revealing a total of four major cell types within the four thalamus sample from mice.
