Spatiotemporal immune atlas of a clinical-grade gene-edited pig-to-human kidney xenotransplant

Project description:Pig-to-human xenotransplantation is rapidly approaching the clinical arena; however, it is unclear which immunomodulatory regimens will effectively control human immune responses to pig xenografts. Here, we transplant a gene-edited pig kidney into a brain-dead human recipient on pharmacologic immunosuppression and study the human immune response to the xenograft using spatial transcriptomics and single-cell RNA sequencing. Human immune cells are uncommon in the porcine kidney cortex early after xenotransplantation and consist of primarily myeloid cells. Both the porcine resident macrophages and human infiltrating macrophages express genes consistent with an alternatively activated, anti-inflammatory phenotype. No significant infiltration of human B or T cells into the porcine kidney xenograft is detectable. Altogether, these findings provide proof of concept that conventional pharmacologic immunosuppression is sufficient to restrict infiltration of human immune cells into the xenograft early after compatible pig-to-human kidney xenotransplantation.

Spatiotemporal immune atlas of the first clinical-grade, gene-edited pig-to-human kidney xenotransplant.

Project description:Pig-to-human xenotransplantation is rapidly approaching the clinical arena; however, it is unclear which immunomodulatory regimens will effectively control human immune responses to pig xenografts. We transplanted a gene-edited pig kidney into a brain-dead human recipient on pharmacologic immunosuppression and studied the human immune response to the xenograft using spatial transcriptomics and single-cell RNA sequencing. Human immune cells were uncommon in the porcine kidney cortex early after xenotransplantation and consisted of primarily myeloid cells. Both the porcine resident macrophages and human infiltrating macrophages expressed genes consistent with an alternatively activated, anti-inflammatory phenotype. No significant infiltration of human B or T cells into the porcine kidney xenograft was detected.

Intermittent fasting alters the spatiotemporal atlas of transcriptomes

Project description:Transcription factors may orchestrate the health benefits of intermittent fasting through directing the expression of genome. Here, we find intermittent fasting can spin the spatiotemporal profile of transcription factors, and provide an atlas of transcription factors in biological space, time and feeding regimen.

Comparative single-cell transcriptional and proteomic atlas of clinical-grade injectable mesenchymal source tissues

Project description:Bone marrow aspirate concentrate (BMAC) and adipose-derived stromal vascular fraction (ADSVF) are the most marketed stem cell therapies to treat a variety of conditions in the general population and elite athletes. Both tissues have been used interchangeably clinically even though their detailed composition, heterogeneity, and mechanisms of action have neither been rigorously inventoried nor compared. This lack of information has prevented investigations into ideal dosages and has facilitated anecdata and misinformation. Here, we analyzed single-cell transcriptomes, proteomes, and flow cytometry profiles from paired clinical-grade BMAC and ADSVF. This comparative transcriptional atlas challenges the prevalent notion that there is one therapeutic cell type present in both tissues. We also provide data of surface markers that may enable isolation and investigation of cell (sub)populations. Furthermore, the proteome atlas highlights intertissue and interpatient heterogeneity of injected proteins with potentially regenerative or immunomodulatory capacities.

High-definition spatiotemporal atlas of cholestatic injury and repair.

Project description:Cholestatic injuries, featured with regional damage around the periportal, cause considerable mortality without curative therapies. It is technically challenging to dissect regional cell-cell interactions and molecular changes to fully understand cholangiopathies. Here, we generated a high-definition atlas of spatiotemporal transcriptome during cholestatic injury and repair. Remarkably, cholangiocytes functioned as a periportal hub by integrating signals from neighboring cells. We also dissected periportal damage, spatial heterogenous reprogramming and zonal regeneration, which appeared to be strongly associated with cholangiocyte. Moreover, spatiotemporal analyses revealed a key inhibitory rheostat for hepatocyte proliferation. Together, our study provides a comprehensive resource that is instrumental to demarcate regional cholestatic injury.
