Ribosomes found to induce somatic cell pluripotency

Added: 21.03.2018 2:07 | 7 views | 0 comments

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: 19.03.2018 15:48 | 7 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.

Stem cells sense neighborhood density to make decisions on their behavior

Added: 19.03.2018 15:48 | 1 views | 0 comments

Human skin is a remarkable organ serving as a barrier protecting us from pathogens, toxic substances and others. Our skin needs to constantly renew throughout our lifetime as well as change its size to perfectly fit and cover the body. To fulfill such a complex and dynamic behavior every cell within the skin has a specific task dependent on its position. Scientists have now shown that cell density and crowding play a critical role in instructing single stem cell fate decisions and movement of differentiating cells upwards within the tissue. This ensures that all cell types are correctly positioned within the tissue.

Unraveling how mesenchymal stem cells from gum tissue accelerate wound healing

Added: 19.03.2018 2:11 | 8 views | 0 comments

Researchers set out to determine whether and how gum-derived stem cells play a role in accelerated wound healing. Their results, indicating that these cells secrete tiny vesicles packed with signaling proteins, point the way forward for therapeutic strategies that aim to harness the prowess of stem cells to treat delayed wound healing as well as other conditions that involve an overactive inflammatory response, such as autoimmune diseases.
