Unraveling how mesenchymal stem cells from gum tissue accelerate wound healing

Added: 15.07.2018 18:25 | 4 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.

Turbulence allows clinical-scale platelet production for transfusions

Added: 13.07.2018 4:17 | 16 views | 0 comments

Turbulence is a critical physical factor that promotes the large-scale production of functional platelets from human induced pluripotent stem cells, researchers reportl. Exposure to turbulent energy in a bioreactor stimulated hiPSC-derived bone marrow cells called megakaryocytes to produce 100 billion platelets -- blood cell fragments that help wounds heal and prevent bleeding by forming blood clots.

Scientists create nano-size packets of genetic code aimed at brain cancer 'seed' cells

Added: 13.07.2018 0:17 | 18 views | 0 comments

In a 'proof of concept' study, scientists say they have successfully delivered nano-size packets of genetic code called microRNAs to treat human brain tumors implanted in mice. The contents of the super-small containers were designed to target cancer stem cells, a kind of cellular 'seed' that produces countless progeny and is a relentless barrier to ridding the brain of malignant cells.

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

Added: 11.07.2018 18:49 | 0 views | 0 comments

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.

Kidney podocytes, all grown up

Added: 11.07.2018 18:12 | 13 views | 0 comments

Unlike other human stem cells, Induced pluripotent stem cells (iPS cells) can be produced directly from adult cells. Now, researchers have shown that human kidney podocytes produced from iPS cells via a highly efficient, previously described protocol exhibit transcriptomic and protein expression profiles that match those of mature podocytes -- a feat that no other method has so far been able to achieve. This confirmation gives kidney researchers a tool for investigating human kidney development, function, and disease.
