RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Background:

The islets of Langerhans contain diverse cell types crucial for hormone secretion.
Dysfunction of insulin-producing beta cells is a hallmark of diabetes.
Generating functional beta cells from stem cells is a key therapeutic goal.

Purpose of the Study:

To leverage single-cell RNA sequencing to analyze beta cells in stem cell-derived and primary human islets.
To investigate beta cell characteristics across different maturation and diabetic states.
To overcome limitations of population-level assays in studying specific cell types.

Main Methods:

Single-cell RNA sequencing (scRNA-seq) applied to stem cell-derived and primary human islet cells.
Transcriptional profiling of individual cells within mixed islet populations.
Comparative analysis of cells in various maturation and diabetic conditions.

Main Results:

scRNA-seq enables precise identification and characterization of beta cell subtypes.
Distinct transcriptional profiles were observed in different maturation and diabetic states.
This approach resolves cellular heterogeneity that is masked in bulk analyses.

Conclusions:

Single-cell RNA sequencing is essential for detailed analysis of beta cell biology.
Understanding beta cell heterogeneity is critical for advancing diabetes research and cell-based therapies.
This technology provides insights into islet development and disease mechanisms.
