How 'pioneer' protein turns stem cells into organs
03/04/2020 - Early on in each cell, a critical protein known as FoxA2 simultaneously binds to both the chromosomal proteins and the DNA, opening the flood gates for gene activation, according to a new study. The...
Old human cells rejuvenated with stem cell technology
03/04/2020 - Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study.
Seeing is believing: Visualizing differences in RNA biology between single cells
03/04/2020 - Researchers developed the novel and publicly available computational tool Millefy to visualize heterogeneity in RNA biology between single cells. Using mouse embryonic stem cells and cells from...
Hidden messages in protein blueprints
02/04/2020 - Scientists have identified a new control mechanism that enables stem cells to adapt their activity in emergency situations. For this purpose, the stem cells simultaneously modify the blueprints for...
Advances in production of retinal cells for treating blindness
02/04/2020 - Researchers have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly. Using the CRISPR/Cas9 gene editing, they have also managed...
For clogged and hardened hearts, a mussel is the solution
02/04/2020 - Researchers have developed a stem cell therapy on myocardial infarction, using proteins that can be found in mussels, mussel adhesive proteins.
Modeling the human eye in a dish
02/04/2020 - Researchers have developed and validated a novel PITX2-eGFP hiPSC reporter line to model the development of periocular mesenchymal cells. These findings could help understand how the eye develops...
Stem cells and nerves interact in tissue regeneration and cancer progression
02/04/2020 - Researchers show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem...
Immunotherapy using 'young cells' offers promising option against cancer
02/04/2020 - A new study suggests that the age of certain immune cells used in immunotherapy plays a role in how effective it is. These cells -- natural killer (NK) cells -- appear to be more effective the...
How skin cells prepare to heal wounds
02/04/2020 - Researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for...
Solving the riddle of superbug toxin damage to gut
02/04/2020 - Scientists have revealed that a bacterial superbug can prevent stem cells in the gut from carrying out their vital role of regenerating the inner lining of the intestine.
Inhalation therapy shows promise against pulmonary fibrosis in mice, rats
25/03/2020 - A new study shows that lung stem cell secretions -- specifically exosomes and secretomes -- delivered via nebulizer, can help repair lung injuries due to multiple types of pulmonary fibrosis in mice...
Cells carrying Parkinson's mutation could lead to new model for studying disease
25/03/2020 - Parkinson's disease researchers have used gene-editing tools to introduce the disorder's most common genetic mutation into marmoset monkey stem cells and to successfully tamp down cellular...
A molecular atlas of skin cells
25/03/2020 - Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far...
Bone or cartilage? Presence of fatty acids determines skeletal stem cell development
25/03/2020 - In the event of a bone fracture, fatty acids in our blood signal to stem cells that they have to develop into bone-forming cells. If there are no blood vessels nearby, the stem cells end up forming...
New technique 'prints' cells to create diverse biological environments
25/03/2020 - With the help of photolithography and programmable DNA, researchers have created a new technique that can rapidly 'print' two-dimensional arrays of cells and proteins that mimic a wide...
Blood stem cells boost immunity by keeping a record of previous infections
25/03/2020 - Scientists have uncovered a surprising property of blood stem cells: not only do they ensure the continuous renewal of blood cells and contribute to the immune response triggered by an infection, but...
How stem cells repair damage from heart attacks
25/03/2020 - Researchers have uncovered stem cell-activated mechanisms of healing after a heart attack. Stem cells restored cardiac muscle back to its condition before the heart attack, in turn providing a...
New method to grow human blood vessels
25/03/2020 - A team of researchers recently proved the ability to grow human-derived blood vessels in a pig -- a novel approach that has the potential for providing unlimited human vessels for transplant purposes.
Second patient has been cured of HIV, study suggests
25/03/2020 - A study of the second HIV patient to undergo successful stem cell transplantation from donors with a HIV-resistant gene, finds that there was no active viral infection in the patient's blood 30...
Producing human tissue in space
25/03/2020 - Scientists have sent adult human stem cells to the International Space Station (ISS). Researchers will explore the production of human tissue in weightlessness.
