For a while now, some plastic surgeons have been using stem cells to treat aging, sun-damaged skin. But while they’ve been getting good results, it’s been unclear exactly how these treatments – using adult stem cells harvested from the patient’s own body – work to rejuvenate “photoaged” facial skin.
In this study, researchers investigated if specific targeting of CD133+ glioblastoma with cutting-edge immunotherapy drugs could eradicate the most aggressive subpopulation of cells in the tumour. They also looked at the safety of CD133-targeting therapies on normal, non-cancerous human stem cells including hematopoietic stem cells which create blood cells and progenitor cells which can form one or more kinds of cells.
A recent study from the Mechanobiology Institute at the National University of Singapore has shown that rejuvenated fibroblasts can recover their ability to self-contract. This encouraging discovery holds great potential for applications in regenerative medicine and stem cell engineering.
Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in advanced drug screens and cell-based therapies. However, current image analysis techniques don’t allow researchers to analyze heterogeneous, multidirectional, striated myofibrils typical of immature cells. In the Journal of Applied Physics, researchers showcase an algorithm that combines gradient methods with fast Fourier transforms to quantify myofibril structures in heart cells with considerable accuracy.
EpiBone’s Craniomaxillofacial, or EB-CMF, product is a living, anatomically correct bone graft made from a patient’s own fat-derived stem cells.

As the COVID-19 pandemic enters its third month, businesses in the United States are marketing unlicensed and unproven stem-cell-based "therapies" and exosome products that claim to prevent or treat the disease. In Cell Stem Cell on May 5, bioethicist Leigh Turner describes how these companies are "seizing the pandemic as an opportunity to profit from hope and desperation."
A new study shows how stem cells – which can contribute to creating many parts of the body, not just one organ or body part – are able to postpone their own death in order to respond to an injury that needs their attention. The study was done in planarians, which are tiny worms used as model organisms to study regeneration because of their ability to recover from any injury using stem cells.
People with the genetic condition neurofibromatosis type 1 (NF1) are prone to developing tumors on nervous system tissue.

The findings point to potential new therapeutic targets for people with NF1.

Nicotinamide can inhibit aggressive cell transformations during wound healing and may be key to the development of therapies to treat fibrotic eye diseases
A new study from Washington University School of Medicine in St. Louis 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 earlier they are in development, opening the door to the possibility of an immunotherapy that would not utilize cells from the patient or a matched donor. Instead, they could be developed from existing supplies of what are called human pluripotent stem cells.

The findings from this experimental study, they say, advance regenerative medicine techniques aimed at reversing the course of diabetic retinopathy and other blinding eye diseases.
Stem cells involved in replenishing human tissues and blood depend on an enzyme known as telomerase to continue working throughout our lives. When telomerase malfunctions, it can lead to both cancer and premature aging conditions. Roughly 90% of cancer cells require inappropriate telomerase activity to survive. In a groundbreaking new study, an interdisciplinary team of Michigan State University researchers has observed telomerase activity at a single-molecule level with unprecedented precision – expanding our understanding of the vital enzyme and progressing toward better cancer treatments.
