Project description:We performed single-cell RNA-sequencing to create a cell census of the human thymus during development, early childhood and adult life. We sampled 15 embryonic and fetal thymi spanning thymic developmental stages between 7 post-conception weeks (PCW) to 17 PCW, and 9 postnatal thymi from paediatric and adult samples. We compared the cellular composition and T cell differentiation within human and mouse thymus using newly generated and repository mouse datasets. Finally, we investigated the bias in the recombination and selection of human versus mouse TCR repertoires.

Project description:Human heart tissue transcriptome was analyzed over a developmental period of 4-8 weeks post-conception. The analysis identifies several modules of co-expressed genes. These modules were tested for significance and disease relevance using other publically available data. This gene expression data was also integrated with the epigenetic data generated in this study to elucidate complex regulatory networks.

Project description:Fetal lung samples at 12–20 post conception week (pcw) from the HDBR, up to 0.5cm3 in size, were embedded in OCT and flash-frozen in dry-ice cooled isopentane. Twelve-micron cryosections were cut onto Visium slides, haematoxylin and eosin stained and imaged at 20X magnification on a Hamamatsu Nanozoomer 2.0 HT Brightfield. These were then further processed according to the 10X Genomics Visium protocol, using a permeabilization time of 18 min for 12–17 pcw samples and 24 min for 19 pcw and older samples. Images were exported as tiled tiffs for analysis. Dual-indexed libraries were prepared as in the 10X Genomics protocol, pooled at 2.25 nM and sequenced in 4 samples per Illumina Novaseq SP flow cell with read lengths of 28 bp for R1, 10 bp for i7 index, 10 bp for i5 index, 90 bp for R2.

Project description:Defects in patterning during human embryonic development frequently result in craniofacial abnormalities. The gene regulatory programs that build the craniofacial complex are likely controlled by information located between genes and within intronic sequences. However, systematic identification of regulatory sequences important for forming the human face has not been performed. Here, we describe comprehensive epigenomic annotations from human embryonic craniofacial tissues and systematic comparisons with multiple tissues and cell types. We identified thousands of tissue-specific craniofacial regulatory sequences and likely causal regions for rare craniofacial abnormalities. We demonstrate significant enrichment of common variants associated with orofacial clefting in enhancers active early in embryonic development, while those associated with normal facial variation are enriched near the end of the embryonic period. These data are provided in easily accessible formats for both craniofacial researchers and clinicians to aid future experimental design and interpretation of noncoding variation in those affected by craniofacial abnormalities.

Project description:Retina is the innermost, light-sensitive layer that lines the back of the eye and is vital for light sensing and image processing. All the retinal cells types are derived from retinal progenitor cells (RPCs) in an orderly spatio-temporal manner that has been well studied in vertebrates. To better understand the emergence of RPCs, their localisation and differentiation to retinal lineages, we performed single cell (sc) RNA-Seq of 24 samples spanning 13 time points from 10-21 post-conception weeks of human development. Several types of progenitors were identified, including early and late RPCs which in turn gave rise the transient neurogenic progenitors that differentiated to all retinal neurones. Spatial transcriptomic analyses combined with scRNA-Seq revealed localisation of early RPCs in the ciliary margin of developing human retinas up to 10 PCW of development and propagation of neural retina differentiation from the centre to the periphery. Single cell ATAC-Seq analyses of 11 samples spanning 8-21 PCW of human development identified Hippo-Yap signalling as key pathway regulating RPC proliferation and cell cycle exit. These results provide the molecular map of human retinal development which may help guide generation of RPCs from human pluripotent stem cells and the design of cell-based replacement therapies for treating retinal dystrophies
