Summary
The mir-290 microRNA cluster controls the cell cycle in mouse embryonic stem cells. This regulation centers on the cyclin-dependent kinase inhibitor p21(Cip1).
Area of Science:
- Developmental Biology
- Molecular Biology
- Genetics
Background:
- Embryonic stem cells (ESCs) possess unique self-renewal and differentiation capabilities.
- Cell cycle regulation is crucial for maintaining ESC pluripotency and genomic stability.
Purpose of the Study:
- To elucidate the regulatory mechanism of the mir-290 microRNA cluster in murine ESCs.
- To identify key targets involved in mir-290-mediated cell cycle control.
Main Methods:
- Analysis of microRNA expression patterns in ESCs.
- Functional studies involving mir-290 cluster manipulation.
- Western blotting and quantitative PCR to assess protein and gene expression.
Main Results:
- The mir-290 microRNA cluster was identified as a key regulator of the ESC cell cycle.
- Downregulation of p21(Cip1) by mir-290 was observed.
- Aberrant cell cycle progression was noted upon disruption of mir-290 function.
Conclusions:
- The mir-290 cluster plays a vital role in maintaining the cell cycle dynamics of murine ESCs.
- p21(Cip1) is a critical downstream target of mir-290 in this regulatory pathway.

01:14Maintenance of the ES Cell State
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...
00:58Embryonic Stem Cells
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.
00:57Embryonic Stem Cells
Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.

01:10Zygotic Development And Stem Cell Formation
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
01:28The Cell Cycle Control System
The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.

02:11The Cell Cycle Control System
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...
