Hydra vulgaris Genome

Overview

The adult Hydra polyp continuously renews all of its cells using three separate stem cell populations, but the genetic pathways enabling this homeostatic tissue maintenance are not well understood. We used Drop-seq to sequence the transcriptomes of 24,985 single Hydra cells to uncover the molecular signatures of a broad spectrum of cell states, from stem cells to terminally differentiated cells. This portal presents these data in an interactive format, and allows for visualization of sequencing statistics, clustering results, and gene expression across every cell in our dataset.

How to use this portal

Using the tabs at the top, users can explore the following information: Cell Info vs Gene Expression, Cell Info vs. Cell Info, Gene Expression vs. Gene Expression, Gene Coexpression, Violin Plot/Box Plot, Bubble Plot/ Heat map, Funtional Annotations and Conversion tables.

CellInfo vs GeneExpr

Cell information vs gene expression on dimension reduction

In this tab, users can visualise both cell information and gene expression side-by-side on low-dimensional representations.
To use these tabs, the user selects the desired dimension reduction for the X- and Y-axes using the drop down menu. For cell information, users can visualize cell types or library batches using the drop down menu. For gene expression information, users can visualize genes of interest by exploring the drop down menu or typing in their gene of interest. Gene expression is colored in a White-Red color scheme which can be changed in the plot controls (see Advanced Options section).

CellInfo vs CellInfo

Cell information vs cell information on dimension reduction

In this tab, users can visualise two cell informations side-by-side on low-dimensional representations.
To use these tabs, the user selects the desired dimension reduction for the X- and Y-axes using the drop down menu. For cell information, users can visualize cell types or library batches using the drop down menu. Categorical covariates have a fixed color palette while continuous covariates are colored in a Blue-Yellow-Red color scheme which can be changed in the plot controls (see Advanced Options section).

GeneExpr vs GeneExpr

Gene expression vs gene expression on dimension reduction

In this tab, users can visualise two gene expressions side-by-side on low-dimensional representations.
To use these tabs, the user selects the desired dimension reduction for the X- and Y-axes using the drop down menu. For gene expression information, users can visualize genes of interest by exploring the drop down menu or typing in their gene of interest. Gene expression is colored in a White-Red color scheme which can be changed in the plot controls (see Advanced Options section).

Gene coexpression

Coexpression of two genes on reduced dimensions

In this tab, users can visualise the coexpression of two genes on low-dimensional representions.
To use these tabs, the user selects, the desired dimension reduction for the X- and Y-axes using the drop down menu. For gene expression information, users can visualize genes of interest by exploring the drop down menu or typing in their genes of interest. For Gene 1, gene expression are colored in a White-Red color scheme which can be changed in the plot controls (see Advanced Options) For Gene 2, gene expression are colored in a White-Blue color scheme which can be changed in the plot controls (see Advanced Options). Cells where genes are coexpressed will be colored in purple/pink which can be changed in the plot controls (see Advanced Options).

Violinplot / Boxplot

Cell information / gene expression violin plot / box plot

In this tab, users can visualise the gene expression or continuous cell information (e.g. Number of UMIs / module score) across groups of cells (e.g. libary / clusters).
Insert directions here.

Bubbleplot / Heatmap

Gene expression bubbleplot / heatmap

In this tab, users can visualise the gene expression patterns of multiple genes grouped by categorical cell information (e.g. library / cluster). The normalised expression are averaged, log-transformed and then plotted.
