A system of check and balances in the blood

Hematopoietic Stem Cells (HSCs) give rise to blood and immune cells of the body, and are therefore essential for our survival. Scientists have now shown how intracellular signalling can safeguard this delicate balance between activation and dormancy.

Flow of cerebrospinal fluid regulates neural stem cell division

Stem cells in the brain can divide and mature into neurons participating in various brain functions, including memory. In a new study, scientists have shown how this works. They found that ion channels play a key role in mediating force signals to the neural stem cells to activate them.

Study could explain link between high-cholesterol diet and colon cancer

Scientists discovered that boosting mice's cholesterol levels spurred intestinal stem cells to divide more quickly, enabling tumors to form 100 times faster. The study identifies a molecular pathway that could serve as a new drug target for colon cancer treatment.

Embryonic mammary gland stem cells identified

Added: 22.05.2018 23:46 | 11 views | 0 comments

Scientists have identified the mechanisms that regulate mammary gland development. Using a combination of lineage tracing, molecular profiling, single cell sequencing and functional experiments, they have demonstrated that mammary gland initially develops from multipotent progenitors during the early steps of embryonic mammary gland morphogenesis whereas postnatal mammary gland development is mediated by lineage-restricted stem cells.

Researchers report how the Spred1 molecule is involved in hematopoietic stem cell self-renewal. Experiments with mouse models show that under normal conditions, Spred1 acts as a negative regulator, while under diet-induced stress, it protects hematopoietic homeostasis.

Immune cell provides cradle for mammary stem cells

Added: 20.05.2018 16:46 | 20 views | 0 comments

Researchers have made new discoveries about how an immune cell known as the macrophage, which normally fights infection by swallowing foreign invaders, nurtures mammary gland stem cells through a chemical signaling molecule. The study may provide important clues about the roles of macrophages in breast cancer progression.

Ribosomes found to induce somatic cell pluripotency

In 2012, a Japanese research group discovered that human skin cells acquire pluripotency when introduced to lactic acid bacteria (Lactobacillus acidophilus). Now, the same group of researchers have found that the cause of somatic cell conversion into pluripotent stem cells is the ribosome, a protein synthesizing cellular organelle.

Researchers create first stem cells using CRISPR genome activation

Added: 19.05.2018 16:50 | 9 views | 0 comments

In a scientific first, researchers have turned skin cells from mice into stem cells by activating a specific gene in the cells using CRISPR technology. The innovative approach offers a potentially simpler technique to produce the valuable cell type and provides important insights into the cellular reprogramming process.
