Organ-on-a-chip
January 7, 2024 10:09 am | by Helen Knight, MIT News Correspondent | News | CommentsA new technique for programming human stem cells to produce different types of tissue on demand may ultimately allow personalized organs to be grown for transplant patients.
Researchers Help Cells Forget Who They Are
December 22, 2023 10:16 am | by Harvard University | News | CommentsResearchers have identified genes that, when suppressed effectively, erase a cell’s memory, making it more susceptible to reprogramming and, consequently, making the process of reprogramming quicker and more efficient.
Stem Cells Likely to be Safe for Use in Regenerative Medicine
December 18, 2023 11:02 am | by University of Cambridge | News | Commentsresearchers have found the strongest evidence to date that human pluripotent stem cells – cells that can give rise to all tissues of the body – will develop normally once transplanted into an embryo. The findings could have important implications for regenerative medicine.
Vitamin D Could Repair Nerve Damage in Multiple Sclerosis, Study Suggests
December 9, 2023 9:20 am | by University of Cambridge | News | CommentsA protein activated by vitamin D could be involved in repairing damage to myelin in people with multiple sclerosis (MS), according to new research.
Ancient Viral Molecules Essential for Human Development

Researchers Find New Way to Force Stem Cells to Become Bone Cells
November 13, 2023 10:47 am | by UNC | News | CommentsImagine you have a bone fracture or a hip replacement, and you need bone to form, but you heal slowly – a common fact of life for older people. Instead of forming bone, you could form fat. Researchers may have found a way to tip the scale in favor of bone formation.
The Life Story of Stem Cells
November 11, 2023 10:46 am | by Max Planck Institute | News | CommentsStem cells ensure the regeneration and maintenance of the body’s tissues. Diseases like cancer can arise if they spiral out of control. Scientists have designed a mathematical model for mapping the development of populations of haematopoietic, i.e. blood-forming, stem cells with advancing age.
Neurons Reprogrammed in Animals
November 5, 2023 9:42 am | by Harvard University | News | CommentsBuilding on earlier work in which they disproved neurobiology dogma by “reprogramming” neurons — turning one form of neuron into another — in the brains of living animals, researchers have now shown that the networks of communication among reprogrammed neurons and their neighbors can also be changed, or “rewired.”
How Specialized Cells Help Each Other Survive During Stress
November 3, 2023 9:50 am | by The Scripps Research Institute | News | CommentsA team has shown for the first time how one set of specialized cells survives under stress by manipulating the behavior of key immune system cells.
