Neuroendocrine control of planarian regeneration (single-cell transcriptome)

ABSTRACT: Effective tissue regeneration requires cells to perceive the surrounding context and make internal state adaptations that enable context-dependent fate changes in time and space, but the mechanisms underlying this complex process remain unclear. Here, transcriptom sequencing was used for study neuroendocrine control of planarian regeneration.

m6A Modification Regulates Planarian Regeneration [scRNA-seq]

Project description:Regeneration is the regrowth of damaged tissues or organs, a vital mechanism in response to damages from primitive organisms to higher mammals. Planarian possesses active whole-body regenerative capability owning to its vast reservoir of adult stem cells, neoblasts, providing an ideal model to delineate the underlying mechanisms for regeneration. RNA N6-methyladenosine (m6A) modification participates in many biological processes, including stem cell self-renewal and differentiation, in particular the regeneration of hematopoietic stem cells and axons. However, how m6A controls regeneration at the whole-organism level remains largely unknown. Here, we demonstrate that the depletion of m6A methyltransferase regulatory subunit wtap abolishes planarian regeneration, potentially through regulating genes related to cell-cell communication and cell cycle. Single-cell RNA-seq (scRNA-seq) analysis unveils that the wtap knockdown induces a unique type of neural progenitor-like cells (NP-like cells), characterized by specific expression of the cell-cell communication ligand grn. Intriguingly, the depletion of m6A-modified transcripts grn/cdk9 (or cdk7) axis rescues the defective regeneration of planarian caused by wtap knockdown. Overall, our study reveals an indispensable role of m6A modification in regulating whole-organism regeneration.

Large-scale, quantitative proteomics reveals key proteins required for planarian regeneration initiation

Project description:Multi-omics studies are increasingly used to decipher the mechanisms underlying tissue regeneration. However, the use of proteomics for such studies has been limited due to the high cost and relatively low throughput and reproducibility. The genes required for planarian regeneration have primarily been identified based on changes in mRNA transcripts; previous studies have not addressed the possibility of protein upregulation prior to detectable increases in transcript abundance during the early stages of planarian regeneration. Here, we used in-depth high-throughput proteomics approaches to analyze the model planarian Schmidtea mediterranea during regeneration and discovered 13 proteins that are essential regulators of key regeneration steps. Two of these proteins, Troponin T and MRPL18, are key regulators of regeneration initiation and showed increases in protein abundance prior to upregulation at the mRNA level. Extensive comparisons between proteomic and transcriptomic datasets suggested the critical mechanisms beyond the transcriptional level, such as the translational and post-translational levels. In summary, this study revealed key regulators of regeneration in a model organism; furthermore, it established an adaptable spectral library and comprehensive proteomics datasets, enabling future in-depth and multi-omics analyses of planarian biology.

454 Life Sciences/Roche and Illumina sequencing of small RNAs from planarian samples

Project description:Freshwater planarian flatworms possess uncanny regenerative capacities mediated by abundant and collectively totipotent adult stem cells. Key functions of these cells during regeneration and tissue homeostasis have been shown to depend on PIWI, a molecule required for piRNA expression in planarians. Nevertheless, the full complement of piRNAs, and microRNAs (miRNAs) in this organism has yet to be defined. Here, we report on the large scale cloning and sequencing of small RNAs from the planarian Schmidtea mediterranea, yielding altogether millions of sequenced unique small RNAs. We show that piRNAs are in part organized in genomic clusters and that they share characteristic features with mammalian and fly piRNAs. We further identify 61 novel miRNA genes and thus double the number of known planarian miRNAs. Sequencing, as well as quantitative PCR of small RNAs uncovered ten miRNAs enriched in planarian stem cells. These miRNAs are down-regulated in animals in which stem cells have been abrogated by irradiation, and thus constitute miRNAs likely associated with specific stem cell functions. Altogether, we present the first comprehensive small RNA analysis in animals belonging to the third animal superphylum, the Lophotrochozoa, and single out a number of miRNAs that may function in regeneration. Several of these miRNAs are deeply conserved in animals. Small RNAs were sequenced from FACS-sorted neoblast stem cells, untreated planarians and irradiated planarians, depleted of neoblasts

m6A Modification Regulates Planarian Regeneration [RNA-seq]

Project description:The fundamental of regeneration process of invertebrates involves the renewal, differentiation and reprogramming of stem cell in an orchestrated manner. It has been known that N6-methyladenosine (m6A) regulates stem cell renewal and differentiation. It is still unclear if m6A is crucial for the regeneration at whole-organism level. Here, we demonstrate that wtap knockdown mediated m6A depletion impairs planarian regeneration upon amputation. The cell cycle related genes displayed decreased m6A while increased expression levels in response to wtap knockdown. The m6A depletion induced phenotypes can be rescued by double-knocking down these genes together with wtap, suggesting that m6A-mediated cell cycle controls planarian regeneration. Further analysis combining the single-cell sequencing unveils a unique neuronal progenitor-like cell type, named NCC and characterized by specific expression of grn, which is indispensable for neuroregeneration. Overall, our study uncovered an essential role of wtap-mediated m6A modification in regulating stem cell population dynamics and homeostasis in terms of general-body regeneration.
