Summary
Researchers identified novel long non-coding RNAs (lncRNAs) that regulate cellular organelles in pluripotent stem cells (PSCs). This discovery offers insights into stem cell reprogramming and development.
Area of Science:
- Cell Biology
- Genetics
- Developmental Biology
Background:
- Pluripotent stem cells (PSCs) are crucial for regenerative medicine due to their self-renewal and differentiation capabilities.
- The regulation of pluripotency in PSCs involves complex interactions across cellular organelles.
- Understanding inter-organelle crosstalk is key to controlling stem cell behavior.
Purpose of the Study:
- To identify long non-coding RNAs (lncRNAs) involved in regulating multiple cellular organelles within PSCs.
- To investigate the role of lncRNAs in coordinating inter-organelle communication during pluripotency.
- To develop a dataset for studying lncRNA functions in stem cell development.
Main Methods:
- Developed a unique strand-specific RNA-sequencing (RNA-seq) dataset focusing on lncRNAs interacting with mitochondria (mtlncRNAs) and polyribosomes (prlncRNAs).
- Compared lncRNA expression profiles across induced pluripotent stem cells (iPSCs), fibroblasts, and human embryonic stem cells (H9).
- Analyzed differential gene expression to identify key regulatory lncRNAs.
Main Results:
- Identified 11 polyribosome-associated lncRNAs (prlncRNAs) that are differentially expressed in iPSCs compared to fibroblasts and H9 cells.
- These identified prlncRNAs are associated with stem cell reprogramming and the exit from pluripotency.
- Generated a valuable RNA-seq dataset for further investigation of lncRNA functions.
Conclusions:
- lncRNAs play a significant role in regulating cellular organelles and maintaining pluripotency in stem cells.
- The identified prlncRNAs are potential key players in stem cell reprogramming and differentiation.
- This study provides a foundational resource for exploring lncRNA-mediated inter-organelle crosstalk in germ cell development and human reproduction.

3.5K
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.

01:29Somatic to iPS Cell Reprogramming
2.2K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

02:39lncRNA - Long Non-coding RNAs
8.6K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

02:55The Nucleolus
8.9K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

01:14Maintenance of the ES Cell State
2.2K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

01:06Induced Pluripotent Stem Cells
4.1K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
